Councilor – Dan Brabander

Dan Brabander is a Professor of Geosciences, Frost Professor Environmental Sciences, at Wellesley College.

Fostering integration as a way of thinking. Brabander offers “Big Idea” courses that introduce systems thinking in applied and messy problem spaces. Course goals are centered on taking a crude look at the whole to determine a path of inquiry. Approach focuses on transdisciplinary theories (e.g., see open syllabus project: paradigms) while fostering intrinsic motivation through project based collaborative learning. Deliverables are aimed at de novo authorship of scientific narratives. Three recent courses have been designed with these goals as a framework: (1) SUST220(Wellesley) AHSE2199A/SCI2099A (Olin) Paradigms, Predictions, and Joules: A Historical and Scientific Approach to Energy and the Environment (2) GEOS/ES 201 (Wellesley) Environmental, Health, and Sustainability Sciences (3) ASTR/GEOS 120 (Wellesley) Planetary Habitability: Past, Present, and Future. These applied alternative on-ramps into STEM have attracted a higher percentage of both URM and first generation students. In 2010, Brabander was awarded the Wellesley College’s Pinanski Prize for Excellence in Teaching.

Integration leading to new disciplines. Informed by research experiences at both Parsons Lab at MIT and Harvard School of Public Health, Brabander’s current research is at the intersection of environmental health and medical geosciences and has helped shape and define an emergent new discipline: “geohealth.”

Professor Brabander’s research team comprises undergraduates learning science by doing science, citizen scientists, and not for profit organizations. Projects have been featured in numerous media outlets including NPR, ABC news, the Boston Globe, and Time Magazine. His current research focus is environmental geochemistry, health, and sustainable urban agriculture.

2018 CUR Conference

The theme of the 2018 CUR Conference was Creating Collaborative Connections in and through Undergraduate Research. Below are highlighted sessions by GeoCUR councilors and members. Please view the full conference program for a listing of all sessions.


PANEL PRESENTATION: Progress in Scaling Up an Innovative Evaluation Method: Perspectives from Pilot Implementation Sites and Next Steps

Jill Singer | Karen G. Havholm | Jennifer Harris
State University of New York- Buffalo State | University of Wisconsin – Eau Claire | University of Washington

Development and pilot testing of an evaluation method for summer research programs is discussed. The method involves multiple assessments of student knowledge and skills for 11 outcome categories each defined by multiple components. Mentors assess students, students self-assess, and mentor-student pairs experience repeated structured interactions to help students reflect and identify content knowledge and skills they desire to improve. A “dashboard” facilitates tracking. Panelists represent institutions that pilot tested the method. Discussion includes refinement of the method, the next round of pilot testing, and plans for eventual broader distribution.

 

PANEL PRESENTATION: Creating Successful Undergraduate Research Connections between Two-Year and Four-Year Colleges and Universities

Jennifer A. Lanter | Diana Spencer | Michelle Hayford | Prajukti Bhattacharyya | Jane Lehr
Moraine Park Technical College | Tulsa Community College | University of Dayton | University of Wisconsin – Whitewater | California Polytechnic State University- San Luis

This session will bring together individuals active in undergraduate research, scholarship, and creative activities at two-year colleges with those at four-year colleges and universities to discuss opportunities and pathways that allow student researchers to transition seamlessly from two-year to four-year institutions. The goal of this session is to share best practices, as well as the benefits and challenges, of connecting two-year and four-year undergraduate research experiences for students and related professional development for faculty.

 

PANEL PRESENTATION: Building Collaborative Relationships: Discussion of Vignettes Showcasing Innovative Relationships Designed to Support Student Learning

Jennifer A. Lanter | Aaron Richard Sakulich | Michael Jackson | Mark L. Lord
Moraine Park Technical College | Worcester Polytechnic Institute | Millersville University | Western Carolina University

The Council on Undergraduate Research’s Innovation and Collaboration Task Force, consisting of Councilors from several CUR divisions, has developed a website to collect, peer review, and share case-study examples of collaborations that support opportunities, resources, and/or success for undergraduates. In this panel we will discuss the information available on the website, as well as the vignette submission and review process. In all, our goal is that, through sharing these examples – both on the website and at the conference—we will inspire others to engage in innovative and collaborative activities.

 

POSTER: The Essential Role of Information Literacy in Basic Undergraduate Research Skills

Laura A. Guertin
Penn State Brandywine

As undergraduate student researchers, students are creators of new knowledge while at the same time are required to interact with existing information. Knowing how and where to find material and answers to questions in the earliest stage of the research process is not a skill we can assume students have when they arrive at our universities. Collaboration between a discipline faculty member and a faculty reference/instruction librarian can result in several possible approaches to establishing a foundation in information literacy for students to then pursue undergraduate research experiences.

 

POSTER: Integrating Student Feedback and Evaluation: A Different Approach to Identifying and Documenting the Impact of Undergraduate Research
Jill Singer | Jennifer Harris | Karen G. Havholm
State University of New York – Buffalo State | University of Washington | University of Wisconsin – Eau Claire

With funding from the NSF WIDER program, an evidence-based evaluation model for guiding undergraduate research is being piloted. The model involves progress assessments by faculty and students across a wide range of learning outcomes. Through repeated structured interactions between student and mentor at the beginning, middle, and end of research, the evaluation helps students recognize and better understand strengths and weaknesses, as well as providing institutional assessment data beyond that self-reported by students. Through collaborations with CUR and SERC at Carleton College, we currently are pilot testing and refining the evaluation model.

University of North Carolina at Greensboro | East Carolina University | Appalachian State University | High Point University

Public and private North Carolina colleges and universities work, collectively, to help promote undergraduate research and creative inquiry as a pathway to learning process through discovery. These efforts are coordinated by faculty/UR program directors from both state and independent institutions. The presenters will discuss the successful programs that have evolved from these collaborations and best and worst practices. Participants will be able to leave with models and ideas for developing or strengthening efforts to grow regional programs that forge collaborations among a variety of universities and colleges.

 

PRESENTATION: OUR Explorers: A Program to Expose Undergraduates to Research Opportunities across Campus

Allison Beauregard-Schwartz University of West Florida

The University of West Florida (UWF) Office of Undergraduate Research (OUR), recently launched the OUR Explorers program for underclassmen. The goals for this program are to encourage students to engage in research earlier, to increase engagement in undergraduates research, and to broaden the scope of potential mentors that students consider. OUR Explorers students are matched with three or four faculty “guides” from a broad range of research specialties to shadow for the spring semester, based on the student’s stated interests and career goals.

2016 CUR Conference

The theme of the 2016 CUR Conference was Advancing Undergraduate Research: Collaboration and Innovation in a Global Society. Below are highlighted sessions by GeoCUR councilors and members. Please view the full conference program for a listing of all sessions.


WORKSHOP: Facilitating Instruction and Research with Undergraduates Using Remotely Operable Microbeam Instrumentation

Presenters: Jeffrey G. Ryan | Sven Paul Holbik | James MacDonald | Mary Beck
University of South Florida | Florida International University | Florida Gulf Coast University | Valencia College

Making use of research instrumentation in undergraduate science courses is a common practice, but one that has historically been limited by access to instrumentation, which creates a range of challenges in providing a classroom of undergraduate students with substantive hands-on educational experiences. This NSF-TUES funded Expansion project is building on the success of a CCLI Program funded pilot effort at USF- Tampa in integrating the use of both electron probe micro-analysis (EPMA) and scanning electron microsocopy (SEM) into introductory and upper-level courses in the earth sciences via remote operation technologies. Students use these instruments (housed at the Florida Center for Analytical Electron Microscopy at FIU in Miami, FL) in real time in their classrooms, conducting both structured laboratory activities and open-ended investigations of collected samples. In this “workshop” you will get hands-on experiences with the FCAEM EPMA and SEM instrumentation as well as an overview of instructor and student instructional resources which are provided via the FCAEM website, and a summary of our salient results in terms of student engagement and facilitation of undergraduate research. You will have the opportunity to discuss with our investigator team how you might take advantage of the FCAEM instruments and resources in your own courses, and the chance to schedule mentored use time on one of the FCAEM instruments to familiarize yourself with the system, and try out your analytical/educational strategies. Our TUES project includes funding to support “tryout days” for new instructional users.

 

PANEL PRESENTATION: The Summer Undergraduate Research Fellowship in Earth and Environmental Sciences (SURFEES) Program: Targeting Community College Students through Research Experiences at 4-Year Colleges

Presenters: Christopher Kim | Hesham El-Askary | Rosalee Hellberg
Chapman University

Effectively recruiting and engaging diverse community college students in STEM research experiences is an increasingly important goal of the National Science Foundation, but has not historically been the primary focus of most NSF-REU (Research Experiences for Undergraduates) Site programs. The Summer Undergraduate Research Fellowship in Earth and Environmental Sciences (SURFEES) program at Chapman University, a primarily undergraduate institution in Southern California, is the site of the first NSF-REU program in NSF’s Division of Earth Sciences that selects participants exclusively from local partnering community colleges. The SURFEES program incorporates specific mentor and participant pre-experience training, pre-, mid-, and post-assessment instruments, and programming targeted to the earth and environmental sciences as well as to community college students. Perhaps most importantly, the application, selection and pairing of student participants with faculty mentors was conducted with specific goals of identifying those applicants with the greatest potential for a transformative experience while also meeting self-defined targets of under-represented minority, female, and low-income participants. In this panel discussion, the program’s principal investigator along with SURFEES faculty mentors from disciplines including biology, earth system science and food science will present initial assessment results of the first two participant cohorts from summer 2014 and 2015, discuss lessons learned for creating/adapting an NSF-REU site to involve community college students, and share individual observations about the student-faculty mentoring and research experience associated with this unique program.

 

PANEL PRESENTATION: Investigating the Earth and Other Planets Via Virtual Globes such as Google Earth, NASA World Wind, and Cesium

Presenters: Jeffrey G. Ryan
University of South Florida

Aside from serving as a widely used geospatial visualization platform, Google Earth provides ready access to a large and growing collection of earth and planetary observation datasets, as well as to “crowd-sourced” imagery and visualizations which students can investigate through course-based structured research experiences as well as via independent investigations. These and other geospatial visualization platforms (examples include GeoMapApp/Virtual Ocean, focused on observational data from the world’s oceans and seafloor; and Cesium, a new open-source virtual map and globe engine) present a wealth of opportunities for engaging undergraduates in the interrogation of global datasets. This set of Presentations will highlight investigations of Earth observation datasets accessible through Google Earth Engine, of the extensive NASA database for Lunar and Mars imagery accessible through the Planets option in GE, and of time-slider, Gigapan, and new 3D visualization resources available through the NSF-funded GEODE project (Google Earth in Onsite and Distance Education). Participants will have the opportunity to delve into and evaluate a range of open-source global geo-data resources and visualization tools.

 

PANEL PRESENTATION: Engaging Students in Course-Based Research: Reports from PCAST, NAS, and Examples from Earth/Environmental Sciences

Presenters: Laura A. Guertin | Mark L. Lord | Sarah K. Fortner
Penn State Brandywine | Western Carolina University | Wittenberg University

The national “Engage to Excel” PCAST report (2012) and “Integrating Discovery-Based Research into the Undergraduate Curriculum” NAS Convocation Report (2015) makes a strong call for using research in our courses. Course-based research offers students training and practice with what we do as scientists and helps to bridge the gap between our teaching and our research. In addition, course-based research is inclusive and supports student success. In this session, we will share information from these published reports, provide examples of successful undergraduate research projects in courses, and strategies for involving different components of research into courses at all levels. Participants will leave with a concrete plan for integrating research in one of their own courses.

 

WORKSHOP: Innovation and Collaboration: Creating Opportunities without Reinventing the Wheel

Presenters: Cynthia A Merriwether-DeVries | Sarah K. Fortner | Jon Grahe
Juniata College | Wittenberg University | Pacific Lutheran University

The session will begin with a brief introduction to the history of the Innovation and Collaboration Task Force and the activities conducted in support of the CUR Innovation and Collaboration Strategic Pillar. Participants will be introduced to the newly launched Case Studies in Innovation & Collaboration website to glean ideas for collaboration opportunities applicable to their home institutional environment. Participants will develop a preliminary plan to implement and analyze a project upon their return to their home campuses. Participants will interact with faculty who have successfully implemented demonstration projects presented on the case study website. Participants will be encouraged to consider supports and challenges related to the application of collaboration strategies in their specific discipline and in their specific community contexts. Participants are encouraged to come with specific illustrations of the corporate, public sector and social service organizations in their home communities that could serve as potential community partners. Project ideas generated by faculty or community partners should be summarized by participants prior to the workshop. PLEASE NOTE: If the participant does not have project ideas it is important to consider the unmet needs in their home community and or potential industry partners to approach on return to their home campus. Participants are encouraged to visit the Case Studies website in advance of the workshop.

 

PRESENTER: Teaching Through Research in the Sciences: a Student Cohort Model

Presenter: Weston Dripps
Furman University

All Bachelor of Science students within the Department of Earth and Environmental Sciences are required to complete a senior thesis based on original research completed during the summer prior to the senior year. During fall of their senior year, students enroll in a course designed to methodically guide them through the process of writing their senior thesis. Students meet as a cohort with an instructor twice a week and then individually with their thesis advisor on a weekly basis. The course provides detailed instruction on writing the various components to a thesis and requires that students generate multiple drafts of each section of their thesis with set deadlines. Upon completion of the course, students have written a full draft of their thesis, and have submitted an abstract to a professional meeting. The spring term is used to further revise the thesis, present the work at a professional meeting, and defend the thesis at a public departmental defense. The recent addition of this course to the curriculum has provided substantially more instruction, structure, and collaboration within the research process, has significantly improved the quality of the research work, and has enhanced the thesis learning experience. The cohort model has changed what was previously an individual, independent, fairly isolating thesis experience to a peer supported, communal, collaborative bonding endeavor. This model requires a significant time commitment and active participation by all faculty overseeing thesis projects in order for it to be successful. From a curriculum development standpoint, the course has allowed the department to identify the core skills students need to successfully complete the senior thesis as well as exposed some competency weaknesses (e.g. graphing skills, hypothesis development, managing large datasets), which have subsequently been scaffolded throughout the curriculum, so that students build these skills prior to engaging in the senior thesis.

Poster Title: Analyzing Tornadic Debris Signatures by Integrating Aerial Imagery and Polarimetric Radar Data in GIS
Funding Agency: NOAA OAR Office of Weather and Air Quality
Grant #: NA16OAR4590210

Abstract:The historic April 27th tornado outbreak of 2011 produced 62 tornadoes in Alabama, with the one of the strongest being the EF-5 Hackleburg-Tanner tornado. The UAH Department of Atmospheric Science contracted the Atlantic Group to fly the Hackleburg-Tanner EF-5 tornado track and capture high-resolution swaths of the damage path, as well as the paths for the violent Cullman and Cordova tornadoes.This case study involves detailed analysis of the aerial imagery, including digitizing tree-falls and damage points, and outlining a damage path for the tornado. These analyses are then merged with georeferenced TIFF files (GeoTIFF) of UAH ARMOR (Advanced Radar for Meteorological and Operational Research) polarimetric radar scans of Reflectivity Factor, Radial Velocity, Correlation Coefficient, Differential Reflectivity, and Spectrum width to analyze dual-polarization radarTornado Debris Signature (TDSs) associated with the Hackleburg-Tanner tornado.An analysis ofTDSs from this tornado allows for the characterization of the effects of debris loading as the tornado passed over different types of terrain. Additionally, a large gap in damage from Harvest, AL, to theTennessee state line is being investigated to determine the possibility that the Hackleburg-Tanner tornado dissipated before Franklin County,TN,and another formed along the same path.The combined analysis of aerial imagery and radar data will provide a detailed picture of how the physical damage and radar signatures correlate and the effects of debris loading over different terrain, which will add confidence to future forecasting of tornadic events.

Poster Title: A Reconstr uction of Fire Histor y of the San Juan Islands, Washington
Funding Agency: BLM National Landscape Conservation System Research Support Program (BLM OR-WA District)
Grant #: L14AC00205

Abstract: Coast Salish peoples in the San Juan Islands have traditionally used fire in the grasslands as a way of managing native plant communities for agriculture. Natural fire frequency in the islands is among the lowest in Washington, suggesting that historical fire regimes reflect human influence. As Indigenous groups have largely been displaced since the arrival of Neo-Europeans in the archipelago, fire frequency has decreased, which has impacted the productivity of grassland flora. Using macroscopic charcoal as a proxy for fire frequency and radiocarbon analysis to approximate when these fires occurred, I attempted to reconstruct the fire history of San Juan Islands. I took my samples from four sites that were adjacent to the historical grasslands of Iceberg Point, Lopez Island, and Cattle Point, San Juan Island. Peaks in the macroscopic charcoal count signified unique fire events that were used to create mean fire return intervals (MFRIs).The site that was closest to the historical grasslands had the lowest MFRI of 42 years and the site furthest from historical grasslands had the greatest MFRI of 133 years. I also conducted interviews with Coast Salish individuals to glean more knowledge of traditional management techniques through the use of fire. Since there is a general concern about the encroachment of shrubs and invasive species into highly diverse grasslands not only in the San Juan Archipelago but throughout the Pacific Northwest, data on previous management techniques using fire could inform current management solutions.

Poster Title: Magmatic Timing in an Ancient Rift

Abstract:The Wichita Mountains in southwestern Oklahoma expose approximately a dozen granite intrusive bodies (plutons), all part of magmatism within an ancient tectonic rift known as the Southern Oklahoma Aulacogen, a feature that stretched from Dallas, Texas, across Oklahoma, past Amarillo to eastern Utah. At the margin of one of the intrusive bodies, the Quanah Granite Pluton, we noted three rock types.These are (1) the typical coarse-grained facies (CF), (2) fine-grained facies (FF), and (3) porphyritic facies (PF).They are distinguishable based on grain size and mineral content. CF has 6mm mineral grains, FF has 2mm mineral grains, and PF has 5mm larger alkali- feldspar grains with a sub-millimeter matrix. Additionally, the intrusive margin contains several pegmatite bodies, these are coarse-grained igneous pods and linear, intrusive features. Mapping the FF and PF revealed these to have linear, intrusive geometries that cut the CF.To resolve relationships, we assessed the mineral content of the three rock types through petrological and geochemical techniques. Prior researchers noted CF’s distinct mineral populations, which include the sodic amphiboles. PF contains the minerals biotite and/or calcic amphibole. FF contains only biotite.The pegmatite bodies contain quartz ± orthoclase ± biotite or sodic amphibole.,The textures and mineral assemblages imply that the voluminous CF magma first intruded this area, followed by distinct magma(s) that gave rise to the FF and PF.The difference in texture suggests the FF and PF record the last gasps of magmatism in the rift.

Poster Title: “Bioavailability of Pb in Urban Soils”

Abstract: Children living in urban areas continue to have a higher risk of lead poisoning than those living in rural areas. An often overlooked source of lead exposure is found in urban soils, which store lead introduced to the environment as a result of the past use of leaded gasoline and leaded paints, as well as industrial emissions of lead. While many studies have quantified the distribution of lead across urban areas, few studies have assessed the bioavailability of lead in these urban soils.The samples used in this study were collected in Terre Haute, Indiana.Total lead concentrations for most of the surface soil samples were previously determined, although additional samples were collected in May 2016 from a historical residential district in Terre Haute.Two different geochemical approaches were used to evaluate the lead bioavailability. Samples were identified with soil lead >200 ppm (n = 210) and subjected to an extraction using a simulated gastric solution to measure what could be absorbed in the stomach during digestion.These samples are currently being subjected to an extraction using simulated bile and porcine pancreatin to measure lead that could be absorbed in the intestines. Samples with lead > 1200 ppm (n= 50) were subjected to a sequential extraction that isolates Pb that is associated with different soil components.The results suggest that soil lead previously considered to be not biologically available could be absorbed in significant quantities during digestion.

Poster Title: “Utilizing Landslides in Lake Champlain as Paleoseismic and Paleohazard Indicators”
Sponsoring Agency: Middlebur y College Senior Research Fund, Lake Champlain Research Consor tium, and Lintilhac Foundation

Abstract: Lacustrine landslides have been identified in Lake Champlain via Multibeam and CHIRP (compressed high-intensity radar pulse) seismic profile imagery. Previous studies show that several of these landslides are coeval occurring ~4500 – 5500 cal yr BP.This study focuses on a series of four overlapping landslide deposits on the western side of the main section of Lake Champlain between Bouquet River Delta and Essex, NY, where nearly the entire slope has failed with the exception of a few locations where intact blocks of slope sediment remain. Utilizing radionuclide dating on sediment from the unfailed slopes, sedimentation rates were determined and used to calculate the approximate failure ages for each of the four landslides studied.,The northernmost failure occurred about 950-1200 cal yr BP, and is the first mass wasting event of this age to be recorded on Lake Champlain.The remaining regions failed about 4500-5200 cal yr BP, and agree with the previously studied landslides within Lake Champlain. In the nearbyWestern Quebec Seismic Zone (WQSZ),clusters of terrestrial landslides have occurred at 1000 and 5000 cal yr BP,and are triggered by large earthquakesThe 5000 cal yr BP event has been attributed to a M 6.4 or greater earthquake within the WQSZ.The landslides observed in Lake Champlain are likely triggered by this same earthquake. Additionally, lake tsunami models show that these simultaneous landslide failures can generate a surface water wave of 30 feet that can impact the shoreline within 3-10 minutes after the earthquake.

Poster Title: “Establishing an Environmental Baseline for Surface and Groundwater Chemistry in Western Wisconsin: Key to Developing Reasonable and Responsible Regulations”

Abstract:The high demand for silica sand by the petroleum industry has led to a dramatic expansion of silica sand mining in westernWisconsin.That has generated immense public concern about the potential environmental impact to surface water and groundwater.TheWisconsin Department of Natural Resources has proposed water quality regulations on silica sand operations that the industry considers onerous. Documentation of the natural concentration and mobility of trace elements in the environment is a critical first step in the development of environmental safeguards.This investigation will establish a comprehensive environmental baseline documenting background variations of ~25 trace metals in natural waters throughout the region.This study will constrain the concentration and mobility of trace metals that occur naturally in geologic formations. Chemical analysis of ~70 surface water, 50 municipal groundwater, and 50 whole rock, mine tailings, and wasterock storage pile samples will constrain the relationship between the bedrock trace metal content and the composition of natural waters. Preliminary results suggest limited trace metal mobility between geologic formations and surface water and groundwater, and trace metal values (e.g., arsenic, lead, cadmium, zinc) are well below federal drinking water standards. Integrating these data with site-specific analyses of surface water and groundwater at mine sites will permit quantification of potential contaminants generated during the mine process. These data are vital to the development of reasonable and responsible environmental safeguards that will facilitate economic growth and sustainable development of the silica sand industry, while safeguarding water resources and public health in western Wisconsin.

Title: Obser vations and Simulations of Whistler Waves in the Van Allen Radiation Belts

Abstract:When the first American satellite, Explorer I, was launched into space it inadvertently discovered one the most significant features of our local space environment: the Van Allen Radiation Belts. This region contains highly energetic particles which are trapped in the geomagnetic field. These particles are extremely hazardous for spacecraft, causing damage to electronics and endangering astronauts on the International Space Station. Certain natural or artificial events, such as coronal mass ejections or high-altitude nuclear explosions, can enhance the Radiation Belts and decrease satellite lifetimes from years to months.Therefore, one of the most critical national defense objectives is to develop a process to remediate the radiation and protect our assets in space from this threat. Our research involves one promising remediation mechanism based on the interactions between these particles and very-low-frequency electromagnetic waves known as whistlers. One important property of whistler waves is that they can be guided along narrow inhomogeneities of plasma density called ducts.To understand the ducting mechanism one needs to compare theoretical predictions with in-situ observations of waves and particles in the magnetosphere. We have analyzed several events of ducted whistlers observed by the Van Allen Probes satellites and reproduce them with numerical simulations based on whistler theory.We demonstrate good, quantitative agreement between our simulations and the observations, indicating that our model successfully explains a majority of the existing satellite observations and can be used to predict the results from future experiments of launching whistler waves into the Radiation Belts from ground transmitters and spacecraft.

Poster Title: “Monitoring Increased Nutrient Loads on a Lake Acting as a Heavy Metal Reservoir”

Abstract: GreenValley Lake State Fishing Area in west-central Indiana once served as a water supply reservoir for the adjacent and now abandoned GreenValley Coal Mine (operated from 1948-1963).The mine property continues to discharge acidic drainage despite reclamation efforts into GreenValley Lake and the connected Scott Lake Fish and Wildlife Areas.To evaluate the variability of metal and nutrient loads over time, two short sediment cores were collected from Green Valley Lake in spring 2014 (38cm) and spring 2015 (39cm). Metal concentrations were determined by a portable X-ray fluorescence analyzer after the cores were separated into 0.5 cm samples. Approximately 20% of the metal concentrations will be verified by ICP-OES following extraction in 50% aqua regia. Detailed phosphorus (P) geochemistry was determined using a sequential extraction technique (SEDEX).The sediments in the lake are characterized by heavy metal concentrations elevated above typical background levels. These metals tend concentrate near the sediment water interface, often 2-5 times greater than the average for the sediments below.This suggests they are diagenetically mobile, possibly diffusing out of the sediments under low oxygen conditions and returning to the sediments when oxygen returns.The most dramatic shift in the detailed P geochemistry is the significant reduction of mineral P at 15 cm and increasing importance of oxide-associated and adsorbed P upcore. Diatom assemblages suggest increasing eutrophication. As nutrient loads continue to increase, the oxygen depleted zone may expand impacting fish populations and change water geochemistry significantly, in particular by mobilizing heavy metals.

Poster Title: “Is cycling as an active transpor tation more than environmentally friendly?—Impacts of bicycle networks on property values in Madison,WI”

Abstract: Whether it is a simple bike path in a park or a complex network of trails and bike lanes, bicycling infrastructure positively impacts the economy. Networks promote active transportation which results in both public and personal economic benefits.The community benefits from reduced infrastructure and health costs, reduced vehicle emissions, and increased revenues to local businesses. Individuals benefit through a healthier lifestyle as well as reduced transportation and medical expenses.There is also an economic effect on property values. Opinions vary whether a bike trail will increase or decrease the value of properties near it.While opponents feel that privacy decreases and crime increases near a bike trail, most studies have shown that bike trails will increase property values. ,This study focuses on the effect bicycle trails have on property values in Madison, WI. Madison has a well-developed cycling network which acts as a corridor for transportation and recreation. While only 0.6% of workers in the U.S. commute to work by bicycle, the percentage is much higher in Madison at 5.3%. In this study, through the use of geographic information system (GIS), maps were created and statistical analyses were run to determine how assessed values of single family residential properties vary by the home’s proximity to the nearest off-street, paved bike trail.

Incredible! #Repost @cofcnaturalhistory with @get_repost ・・・ Student volunteers and researchers revealing the past - as recently highlighted by @postandcourier! There is so much to do in order to keep CCNHM running that we rely on a small corps of student volunteers, docents, and junior scientists to maintain CCNHM as a center of natural history at @collegeofcharleston. Visitors are most familiar with our student docents - but may not be as familiar with the behind the scenes activities. Our volunteers are primarily students and retirees, and are responsible for cleaning fossils off, reassembling broken fossils, and producing mounts that keep the fossils safe during long term storage. Geology Junior Suzanne Grantham (top) is currently working on reassembling a fossil dolphin - well, it's actually two dolphins that died near eachother, and their bones became fragmented and the fragments mixed together. (...fun) We have one student researcher at present: Bailey Fallon (bottom), a junior in Biology, who is studying fossil leatherback sea turtles from the Charleston area, and has already had her first research manuscript go through peer review! Next semester Suzanne is considering joining the research team, as is another student, Nathan McCuen - they will be studying South Carolina cetaceans and mosasaurs (respectively).

#Repost @americangeophysicalunion with @get_repost ・・・ To round out women’s History Month, AGU is celebrating the geoscience discoveries and advances made by women. Here’s the second of ten: Inge Lehman discovers Earth’s inner core is solid in 1936, which helps explain how the core generates Earth’s magnetic field. #agu100 #women #womenshistorymonth#womenempowerment #geoscience #science#womeninstem #earth #discovery
#Repost @usinterior with @get_repost ・・・ One of the longest continuously inhabited landscapes in North America, Canyon de Chelly National Monument is a place of natural beauty and living legends. A dry climate, sheltering cliffs and the watchful eyes of local residents protect the distinctive architecture, artifacts and rock imagery. Completely within the Navajo Nation in #Arizona, the park’s signature vista is looking down at Spider Rock, an 825-foot-tall sandstone spire that got its name from the Navajo story of the Spider Woman. Rangers and #Navajo guides share these stories to connect visitors to this special place.
