- S1. Contributions to New England Stratigraphy & Structure: In Honor of Robert Moench & Douglas Rankin.
Greg Walsh, U.S. Geological Survey, gwalshusgs.gov; Wally Bothner, Univ. of New Hampshire, wally.bothnerunh.edu; Mark Van Baalen, Harvard Univ., mvbharvard.edu.
- The careers of Doug Rankin and Bob Moench span the full 50-year history of the Northeastern section of GSA. Their contributions to the tectonics, stratigraphy, and evolution of the Appalachians and beyond will be honored at this symposium, which will include both oral and poster sessions. A reception will follow. Please help us pay tribute to two iconic geologists who have led us to paradigm shifts in earth science in the Northeast.
- S2. Coastal and Glacial Processes from Alaska to New England: In Honor of Jon Boothroyd.
Bryan Oakley, Eastern Connecticut State Univ., oakleybeasternct.edu; Mark Borrelli, Center for Coastal Studies, mborrellicoastalstudies.org.
- This symposium is being held in honor of Jon C. Boothroyd, research professor emeritus, Department of Geosciences, University of Rhode Island, and Rhode Island State Geologist. The focus of Jon’s career at URI has been on the coastal and glacial processes within Rhode Island, throughout New England and beyond, including Ecuador, Madagascar and the Azores, and of course he did extensive fieldwork in Alaska. Beyond a wide geographic scope, Jon’s career spanned many depositional environments, and so we invite talks focusing on modern coastal, glacial, estuarine, and shoreface processes throughout the world. We are particularly interested in presentations from colleagues and former students who have collaborated with or been influenced by Jon.
- S3. Climate Change in Space & Time: An Update.
P. Thompson Davis, Bentley Univ., pdavisbentley.edu; Jeremy Skakun, Boston College, jeremy.shakunbc.edu.
- Human-induced climate change is superimposed on myriad natural climate changes on a variety of spatial and temporal scales. Proxy-based reconstructions of past environmental and climatic change provide critical data for assessing current and future environmental and climatic conditions. This symposium will examine the history of climate and environmental change recorded in physical, chemical, and biologic proxy records. The development of new proxy indicators of global change and new methodologies will also be considered. We seek oral and poster presentations that address any aspect of climate change on any time scale, not necessarily restricted to northeastern North America.
- S4. Contributions of Cosmogenic-Nuclide Geochronology to Glacial Geology and Geochronology in northeastern North America—and Vice Versa.
Greg Balco, Berkeley Geochronology Center, balcsbgc.org; John Gosse, Dalhousie Geochronology Centre, john.gossedal.ca.
- This session is intended to highlight the mutually beneficial interaction between glacial geologists and cosmogenic-nuclide exposure-dating specialists in the past several years. The detailed deglaciation chronology for northern New England and adjacent regions facilitates accurate calibration of cosmogenic-nuclide production rates, and exposure-dating techniques, in turn, provide a new means of extending the chronology of Laurentide Ice Sheet deglaciation to times and places lacking radiocarbon or varve age constraints. We invite contributions from anyone working to calibrate production rates against existing deglaciation chronologies; use exposure-dating methods to fill gaps in understanding of LGM and late-glacial ice sheet-climate interactions; or apply cosmogenic-nuclide methods to quantify rates of glacial or postglacial erosion and landscape formation.
- T1. Updating the Orogen: Along- Strike Tectonic Correlations and Comparisons in the Northeastern Appalachians.
Jon Kim, Vermont Geological Survey, jon.kimstate.vt.us; Craig Dietsch, Univ. of Cincinnati, dietsccucmail.uc.edu.
- Well-established terrane correlations and tectonic models in the northeastern Appalachians have recently been challenged by new geochemical and geochronologic data. The focus of this session is to highlight research bearing on along-strike correlations and comparisons with the goal of improving our geodynamic interpretation of the orogen. Contributions bearing on tectonostratigraphy, terrane provenance, structural geology, petrology, geochemistry, and geochronology are encouraged.
- T2. Northeastern North American Volcanic Successions and Their Tectonic Context.
Sheila Seaman, Univ. of Massachusetts, sjsgeo.umass.edu; Christopher Koteas, Norwich Univ., gkoteasnorwich.edu.

- T3. Terrane Forensics—Where Did They Come From and Which Are Related?
Sandra Barr, Acadia Univ., sandra.barracadiau.ca; Scott Samson, Syracuse Univ., sdsamsonsyr.edu.
- This session is intended to focus on the bigger picture implications of the detailed data bases that have been built over decades of work in the Appalachian orogen and elsewhere but which still do not seem to answer the fundamental questions of “how different is different, and how similar is similar?” We hope to attract presentations that investigate the questions from all subdisciplines, including but not limited to paleontology, geochronology, isotope geology, and geochemistry, and from a global perspective.
- T4. Ages and Origins of Intrusive Rocks in the New England Appalachians.
Dyk Eusden, Bates College, deusdenbates.edu; Dwight Bradley, U.S. Geological Survey, dbradleyusgs.gov.
- The New England Appalachians are host to intrusive rocks that range in age from Mesoproterozoic to Cretaceous. Recent advances in geochronology, geochemistry, and petrogenesis have shed new light on the origins of these igneous suites, which number at least a dozen. In addition, the list of possible triggers for magma genesis has grown to include not only subduction, crustal thickening, lithospheric extension, and mantle plume activity, but also orogenic collapse, lower-lithosphere foundering or detachment, ridge subduction, and slab breakoff.
- T5. The Role of Interacting Processes in Deformation.
Jeff Marsh, Queens College, jhmarsh00gmail.com; Chris Gerbi, Univ. of Maine, christopher.gerbimaine.edu; Scott Johnson, Univ. of Maine, johnsonsmaine.edu.
- Deformation of Earth’s lithosphere commonly involves a number of complex, interrelated geological processes, including metamorphic transformations, fluid transport, melting, and microstructural change, with each capable of operating over different timescales and causing significant changes in bulk rheology. This session invites theoretical, experimental, field-based, and modeling studies on those and related topics at all scales. We encourage a broad range of contributions, with the goal of providing a forum for multidisciplinary conversations discussing emerging ideas about the chemical-mechanical nature of the lithosphere, integrating aspects of structural geology, metamorphic and igneous petrology, geochronology, geophysics, and other fields.
- T6. Retracing the Steps of Northeastern U.S. Geologists in the Past 50 Years.
Jeri Jones, Jones Geological Services, jonesgeocomcast.net.
- With the complex geology of the Northeastern United States, some of the most famous geologists ever to lay their hammer on a rock researched this region. As the theory of plate tectonics was in its infancy 50 years ago, their research laid the foundation of establishing early reconstruction models of the development of the Northeast bedrock. Papers or posters are invited to honor these researchers who published classical reports that are still used as reference material today.

- T9. New Perspectives on Paleoclimate from Advances in Glacial Geology.
Meredith Kelly, Dartmouth College, meredith.kellydartmouth.edu; Alice Doughty, Dartmouth College, alice.doughtydartmouth.edu; Margaret Jackson, Dartmouth College, margaret.s.jackson.grdartmouth.edu.
- Glacial landforms and erosional features provide valuable evidence for past glacial extents. Identifying, mapping and dating these features form the framework for many paleoclimate interpretations. Recent advances in geomorphic mapping using LiDAR and high-resolution satellite imagery enable the documentation of past glacial extents worldwide. Applications of numerical modeling provide further insight into the paleoclimate conditions that influenced past glacial extents. We seek to bring together new research from around the world on glacial geomorphology, absolute dating techniques, and glaciological modeling that elucidates the relationships between past glacial fluctuations and paleoclimate.
- T10. Holocene Paleoclimate Perspectives on Present-Day Arctic Change.
Erich Osterberg, Dartmouth College, erich.osterbergdartmouth.edu; Karl Kreutz, Univ. of Maine, karl.kreutzmaine.edu; Lisa Doner, Plymouth State Univ., ladonerplymouth.edu.
- Paleoclimate studies play essential roles in understanding current and future rapid changes in the Arctic. The Holocene presents an opportunity to develop uniquely diverse, widespread and highly resolved paleoclimate and paleoenvironmental reconstructions characterizing the arctic system during conditions both warmer and colder than today. This session aims to explore the patterns, causes and impacts of Holocene climate change across the Arctic. We seek to bring together Arctic paleoclimate datasets from a wide range of archives including lake and marine sediments, ice cores, tree-rings, landscape morphology, and marine organisms, as well as climate model analyses. We encourage research that addresses aspects of the arctic system (e.g., sea ice, ocean/atmosphere modes of variability, and glacier mass balance) that play important roles in present-day global change.
- T11. Limnological Records in Past, Present, and Future Climates.
Lisa Doner, Plymouth State Univ., ladonerplymouth.edu; Julia Daly, Univ. of Maine, julia.dalymaine.edu; Bradford Hubeny, Salem State Univ., bhubenysalemstate.edu.
- Geologic archives in lakes have long been used to infer past climates. Recently, the urgent need to identify changes in lake systems due to anthropogenic climate forcing and feedback has led to an increase in lake surveying and monitoring. These include data from sediment traps, GPR and seismic surveys, and aspects of lake functioning, such as nitrogen and carbon cycling, identification of isotopic pathways and molecular biomarkers, like GDGTs. These approaches, utilizing the past and the present, are essential aspects of modeling how future climate might impact lake systems, including their watershed services. This session explores ongoing efforts in this direction.
- T12. Pleistocene to Anthropocene Landscape Evolution in the Northeastern U.S.
Will Ouimet, Univ. of Connecticut, william.ouimetuconn.edu; Noah Snyder, Boston College, noah.snyderbc.edu.

Devon Renock, Dartmouth College, devon.j.renockdartmouth.edu; Nathaniel Warner, Dartmouth College, nathaniel.r.warnerdartmouth.edu.
- This session will highlight research on the produced water that flows out of oil and natural gas-bearing Utica and Marcellus Shales. “Life cycle” includes topics ranging from the formation of basin brines to the disposal/treatment of produced water. Specific topics include basin brine formation, water-rock interactions, microbial processes, isotope tracer studies, recycle and reuse, and disposal/remediation practices.
- T22. State and Fate of Urban Watersheds in the Northeast.
Jonathan Gourley, Trinity College, jonathan.gourleytrincoll.edu; Suzanne O’Connell, Wesleyan Univ., soconnellwesleyan.edu.
- Urbanization, increased impervious surfaces, and storm-water runoff have had, and will continue to have, serious impacts on many watersheds throughout the northeastern U.S. and adjoining parts of Canada. This session features research that focuses on the environmental issues that currently face urban watersheds.
- T23. Morphological and Hydrological Responses of Salt Marshes to Anthropogenic and Natural Stressors.
Beverly Johnson, Bates College, bjohnso3bates.edu; Kristin Wilson, National Estuarine Research Reserve, krwillsgmail.com.
- Salt marsh morphology and hydrology are influenced by climate change, sea-level rise, eutrophication, land-use change, and biotic interactions, among others, and are critical components of coastal ecosystems. Morphological and hydrological changes to these habitats may alter salt marsh extent, form, or function, in turn modifying ecosystem services. This session shares new insights into how these stressors and interactions between them, shape salt marsh geomorphology and hydrology.
- T24. Groundwater in the Shallow Coastal Aquifers of the Northeast.
Denis LeBlanc, U.S. Geological Survey, dleblancusgs.gov.
- The shallow unconsolidated coastal aquifers of the northeastern United States are important sources of drinking water and provide critical freshwater discharge to coastal streams, wetlands, and marshes. Land disposal of wastewater has decreased water quality of many coastal aquifers and resulted in excessive nitrogen loads to adjacent coastal waters. Climate change and sea level rise may affect groundwater levels, flow patterns, and the position of the freshwater-saltwater interface. Addressing these challenges will require a sound scientific understanding of the hydrogeology and geochemistry of these aquifers. Presentations are solicited on the hydrogeologic characterization of the shallow coastal aquifers, including groundwater-flow patterns, locations and rates of fresh groundwater discharge to coastal water bodies, the transport of wastewater nitrogen and other groundwater contaminants to coastal discharge locations, and the potential effects of the predicted climate change and sea-level rise on the groundwater systems.
- T25. River Restoration in New England.
Frank Magilligan, Dartmouth College, magilligandartmouth.edu; Carl Renshaw, Dartmouth College, renshawdartmouth.edu; Anne Lightbody, Univ. of New Hampshire, anne.lightbodyunh.edu.
- With its long history of anthropogenic impacts, such as dam construction, urbanization, channelization, and logging, many river systems in New England are far removed from their natural condition. Although river restoration has become an important regional and national strategy to rehabilitate degraded or disturbed river systems, the science of river restoration lags behind its application. To better understand the science of river restoration, we seek oral presentations and posters that address the type, magnitude, and processes of channel adjustment to and recovery from both anthropogenic and natural disturbances. Topics include, but are not limited to, channel recovery to Tropical Storm Irene, the function of large woody debris (LWD) on channel morphology and hydraulics, the impact of (legacy) sediments on reach and watershed scales, geomorphic adjustments to dams and dam removal, the role of river restoration in nutrient retention, and the role of land use and climate change on river dynamics. We welcome research from field studies, modeling, lab experiments, remote sensing and GIS, or other geomorphological, geotechnical, or geochemical approaches.
- T26. Advances in Topobathymetric Mapping, Models, and Applications.
John Brock, U.S. Geological Survey, brockusgs.gov; C. Wayne Wright, U.S. Geological Survey, wwrightusgs.gov.
- Detailed knowledge of temporally varying subaerial and submerged topography is needed by scientists and policy-makers in heterogeneous coastal zones with high-energy physical processes, complex habitats, steep ecological gradients, focused societal infrastructure investments, and concentrated human populations vulnerable to a range of inundation hazards. The latest topographic and topographic-bathymetric (topobathymetric) LiDAR systems and other new techniques offer greatly enhanced littoral zone, estuarine, and inland river channel mapping capabilities and facilitate generation of merged multi-sensor, multi-temporal coastal zone elevation models. Presentations are invited on all aspects of the use of topobathymetric data in mapping and monitoring diverse components of coastal systems, hydrodynamic modeling of tsunamis, improved prediction of storm surge, and in modelling impacts of sea level rise, and other related applications.
- T27. Potential for Geothermal Energy in New England.
Matt Davis, Univ. of New Hampshire, matt.davisunh.edu; Rick Chormann, New Hampshire State Geologist; frederick.chormanndes.nh.gov; Steve Mabee, Massachusetts State Geologist, sbmabeegeo.umass.edu.
- Recent efforts associated with a federal initiative to create a National Geothermal Data System enlisted the state geological surveys in the collection and compilation of data relevant to the potential for geothermal energy development, largely with an emphasis on enhanced geothermal systems. At the same time, demand has been growing for installation of ground source heat pump systems to meet the heating/cooling needs of homes, businesses, and institutions. This session will explore the potential for both electricity production and heat pump applications in the Northeast, given what is currently known about the geologic, geochemical, hydrologic, and climatic conditions, as well as the remaining questions that need to be addressed.
- T28. Disruptive Technology and Geoscience Education.
Declan DePaor, Old Dominion Univ., ddepaorodu.edu; Steve Whitmeyer, James Madison Univ., whitmesjjmu.edu; Callan Bentley, Northern Virginia Community College, cbentleynvcc.edu.
- Professors often complain about disruptive students. Here’s your chance to get even by becoming disruptive yourself—but in a good way! We encourage presentations showing ways that colleagues are disrupting traditional geoscience classrooms to enhance learning by: (1) breaking the lecture/lab/day-trip model; (2) breaking the homework/mid-term/final exam model; (3) facilitating authentic undergraduate research opportunities; and (4) making curricular changes that attract non-traditional students. Suitable topics include technologies for novel presentations and student-professor interactions in large general education and smaller major classes; strategies that attract underrepresented minorities to sign up as geoscience majors—“Failure is not an option!”—and experience offering courses with no D/F grades; virtual apparatus— successes/failures; remote environmental monitoring; augmented reality in the geoscience lab and in the field; virtual field trips on Earth and other planets and their moon systems; data mining and student analysis of Big Geodata; geo–crowd sourcing; digital mapping.
- T29. Innovative and Multidisciplinary approaches to Geoscience Education.
Jennifer Hanselman, Westfield State Univ., jhanselmanwestfield.ma.edu; Jennifer Sliko, Penn State Univ.–Harrisburg, jls1093psu.edu.
- This session focuses on novel pedagogical practices in geoscience courses. Submissions should include practices that promote a deeper understanding of geoscience concepts while considering best practices. Courses may vary in geoscience content, format (online or traditional), and audience.
- T30. Application of Digital Terrain Analysis in Geology, Hydrology, and Geoarchaeology.
Rick Chormann, New Hampshire State Geologist, frederick.chormanndes.nh.gov.
- The increasing availability and accessibility of high-resolution topographic datasets combined with the robust functionality of both open source and proprietary spatial analysis software have created unprecedented opportunities for quantifying land surface characteristics. This session will highlight the use of digital terrain analysis and geomorphometry in studying landforms and earth surface processes from the scale of individual features to entire landscapes. Presentations are invited that demonstrate novel approaches, provide compelling insights and findings, and/or point the way to the future development of tools and techniques.
- T31. Hydropedology at Hubbard Brook Experimental Forest: Landscape Patterns and Hydrologic Processes.
Scott Bailey, U.S. Forest Service, swbaileyplymouth.edu.
- Knowledge of the character of the geologic substrate and processes by which water and biota interact with geologic materials is critical to understanding ecosystem processes, development of soils, stream drainage networks, and groundwater resources, and geographic distribution of plants and other organisms. This session invites presentations that stretch the boundaries of geologic disciplines to develop new ways to analyze environmental patterns and responses to change and disturbance.
- T32. Pegmatite Processes and Problems.
Paul Tomascak, SUNY-Oswego, paul.tomascakoswego.edu; Marin Lupulescu, New York State Museum, mlupulesmail.nysed.gov.
- Recent improvements in the interpretation of some of the mystifying internal features of granitic pegmatites have coupled with increased global interest in strategic metal resources to generate a swell of interest in granitic pegmatites. We seek submissions that highlight research on these important rocks, emphasizing how modern methods are paving the way to new understanding of pegmatite-generating processes, the development of pegmatitic textures, and the sometimes spectacular enrichments of rare elements. We hope that the session will spur discussion on the future research directions that will lead to clearer solution of the persistent problems in pegmatite study.
