 top SYMPOSIA

Presentations for symposia are generally by invitation only, so if you are interested in participating, please contact session coordinators.

1. New England Hydrology: A Tribute to S. Lawrence Dingman.
Ellen Douglas, UMass-Boston[, +1-603-862-2730]
Matthew Davis, University of New Hampshire [, +1-603-862-1718]
Professor S. Lawrence Dingman, who will be honored in this session, devoted his career to studying New England hydrology and to promoting hydrology as a quantitative science. This symposium/session will highlight significant developments in our understanding of hydrologic processes particular to New England and the challenges that face the next generation of hydrologists in this region. We are particularly interested in presentations that highlight Larry's contributions through his research and mentorship.
2. Rev. James W. Skehan SJ — Geologist, Teacher, Mentor, Priest: A Jesuit Journey.
Walter Anderson, Maine State Geologist Emeritus [, +1-207-846-6434]
Chris Hepburn, Boston College [, +1-617-552-3640]
Father Jim, as he is known to one and all around the world, has had a long, distinguished, and varied career, extending for over half a century. This symposium is to recognize and commemorate his many contributions, particularly those to the geology of the northern Appalachians. He was one of the first to recognize the importance of plate tectonics in understanding this mountain belt and its differentiation into terranes, including the extent of the Avalon terrane in SE New England. We hope his colleagues, former students, and many friends will join in celebrating Father Jim's career by contributing modern work or summaries from areas of Jim's interests, tinged, perhaps, with personal recollections of this unique individual.
3. Geology in Service to the Public, and the Revival of State and Provincial Geological Surveys in the Northeast.
David Wunsch, New Hampshire State Geologist [, +1-603-271-6482]
Gary D. Johnson, Dartmouth College [, +1-603-646-2371]
The science of geology has played and will continue to play an important role in the identification, evaluation, utilization, and protection of energy, mineral, and water resources; in the assessment and mitigation of natural hazards; in the assessment and remediation of human impacts on the environment; and in informed planning. This symposium will consider the contributions that state and provincial geological surveys and other engaged earth scientists are currently making toward the challenges that lie ahead as we endeavor to apply our scientific expertise for the public good and the benefit of society.

1. From Rodinia to Pangea — The Lithotectonic Record of Plate Convergence in Eastern North America.
Dick Tollo, George Washington University [, +1-202-994-6960]
Paul Karabinos, Williams College [, +1-413-597-2079]
This session explores the rich record of plate tectonic convergence represented in the Grenville and Appalachian orogens. Ongoing research has documented important variations in the lithologic packages, structural style, metamorphism, plutonism, and duration of individual orogenic events that collectively led to assembly of the supercontinents Rodinia and Pangea. Such studies offer important insight into the character of colliding terranes and the timing, style, and geometry of convergence. We invite researchers to share their findings and contribute to a holistic discussion of convergent tectonics across the traditional boundaries of space and time. Contributions are encouraged across a broad range of topics, including studies concerned with elucidating aspects of the structural mechanics of deformation, nature and geometry of terranes, thermal history associated with the magmatic and metamorphic record of collision, formation and distribution of ores, and geochronological calibration of events and processes.
2. The Neo-Acadian Orogeny and Implications for Tectonic and Depositional Setting of Devonian — Carboniferous Rocks in the Appalachian Orogen.
M.D. Thompson, Wellesley College [, +1-781-283-3029]
C.E. White, Nova Scotia Department of Natural Sciences [, +1-902-424-2519]
Peter Robinson, Geol Survey of Norway []
Collisions between Avalonian and Laurentian elements during the Acadian cycle of Appalachian orogenesis were succeeded in Middle Devonian through Carboniferous time by activity for which the tectonic picture is not so clear. Northern Appalachian events during this interval include not only thick successor basin sedimentation in the Maritimes Basin of eastern Canada, but also "Neo-Acadian" granitoid magmatism and granulite facies metamorphism in central New England, intraplate volcanism and/or plutonism in Avalon terranes of Nova Scotia and southeastern New England, as well as widespread dextral transcurrent motions. Integrating these (and other?) events into the general framework of Meguma accretion and Rheic ocean closure will be the focus of this session, and we invite contributions from any geoscience subdiscipline relevant to this discussion. Also, though examples highlighted here are all from the northern Appalachians, we encourage workers from the southern Appalachians, Central America, and Europe to broaden the discussion with insights from their areas as well. Oral presentations and posters welcome.
3. Tectonic Setting of the Magmatic, Sedimentary and Metamorphic Record of the Alleghanian Orogeny in the Appalachian Mountains.
Bob Wintsch, University of Indiana [, +1-812-855-4018]
C. K. Kerwin, Keene State College [, +1-603-358-2405]
Evidence for the Alleghanian Orogeny in the Appalachians is well preserved in the foreland sediments shed from internal crystalline rocks to the west (e.g., Appalachian basins and beyond) and to the east (e.g., Narragansett basin) and in the structures and metamorphism of these sediments. However, direct evidence of the nature of the involvement of the crystalline rocks in the hinterland of the Alleghanian has been slow in coming. This session invites earth scientists from all disciplines to participate in this wide ranging topic that seeks to better understand what specific processes were activated in the hinterland by the assembly of Pangea and how these led to such extensive sedimentation in the forelands. The session will necessarily integrate many disciplines to identify the linkages between shortening, crustal-scale loading, and metamorphism in the internides with sedimentation and deformation in the foreland.
4. Caledonian Magmatism: Cross-Atlantic Connections — Again.
John Hogan, University of Missouri-Rolla [, +1-573-341-4618]
David Gibson, University of Maine-Farmington [, +1-207-778-7401]
Dan Lux, University of Maine-Orono [, +1-207-581-2152]
Martin Feely, National University of Ireland-Galway [, +353-91-492129]
J. Tuzo Wilson's comparison of the ages and patterns of rock types bordering both sides of the Atlantic led to his formulation of an orogenic cycle, the opening (continental rifting) and then closing (continental collision) of the proto Atlantic Ocean, to explain the geologic history of these regions. Directly and indirectly, the "Wilson Cycle," which originated from cross-Atlantic comparisons, provided the impetus for many studies that led to a refinement of our understanding of orogenic processes. In this spirit, we again (see NE-GSA 2001) invite contributions from researchers on both sides of the Atlantic to discuss similarities and differences in all aspects of igneous rocks associated with Caledonian Orogeny. Studies of igneous rocks provide tremendous insight into the orogenic processes that reshape the crust. For example, studies of igneous rocks can readily provide constraints on the timing of deformational events and motion along faults, characterize terrane boundaries in the upper and lower crust, define the extent of recycling of crustal source materials and juvenile contributions from the mantle, and have the potential to identify tectonic settings. This session is associated with the premeeting Field Trip 4, Igneous Rocks of the Easternmost Three Terranes in Southeastern New England: Examples from NE Massachusetts and SE New Hampshire, which will examine a variety of igneous rocks in eastern Massachusetts and southern New Hampshire and the constraints they place on the geologic history of this region and the processes that lead to the diversity of igneous rocks that characterizes these terranes. We encourage participation in both these venues to maximize discussion and renew productive cross-Atlantic connections. For further information regarding this session, please contact any one of the co-conveners.
5. Mesozoic Extension, Exhumation, Sedimentation and Magmatism in the Northern Appalachians.
Mary Roden-Tice, SUNY-Plattsburgh [, +1-518-564-4032]
Greg McHone, University of Connecticut [, +1-860-486-1391]
Tectonic activity, sedimentation, volcanism, plutonism, and regional uplift were all active in discrete episodes throughout the Mesozoic era in northeastern North America. Our present-day landforms, post-metamorphic rocks, and brittle structures might be better understood by bringing various disciplines into a common meeting with a Mesozoic theme. We invite everyone who is working on Mesozoic rocks, features, and events to participate in this session.
6. Isotopic and Other Indicators of Sediment Provenance and Basement Character.
Sandra Barr, Acadia University [, +1-902-585-1340]
Scott Samson, Syracuse University [, +1-315-443-2672]
Isotopic and other geochemical data are increasingly being utilized in sedimentary and metasedimentary units in the Appalachian orogen as we attempt to refine our understanding of the original relationships among the numerous accreted terranes, both peri-Laurentian and peri-Gondwanan. The intent of this session is to bring together those interested in knowing the sources of sediments deposited in the orogen throughout its history and in understanding what that information might tell us about the unexposed infrastructure of Ganderian and Avalonian terranes. Although the focus will be on sedimentary and metasedimentary rocks, other contributions related to the role of provenance in tectonic studies are also encouraged.
7. Strain Partitioning and Rheological Evolution in Orogens.
Dyk Eusden, Bates College [. +1-207-786-6152]
Scott Johnson, University of Maine [, +1-207-581-2142]
We are seeking presentations on the topic of strain partitioning and rheological evolution in mountain belts. Papers from the northeastern Appalachians as well as those from other orogenic belts worldwide are encouraged. If you or your collaborators or students have been evaluating the distribution of strain, changes in rheology over time, the absolute amounts of strain, or have combined natural observations with numerical or analog modeling experiments, we encourage you to submit an abstract. Broadly structural in topic, this session encourages papers reflecting work at any scale of observation, as well as those that are part of the complex continuum of deformation, metamorphism, and magmatism during orogenesis.

8. Sedimentological and Stratigraphic Studies in the Gulf of Maine.
Sponsored by the Eastern Section of the Society for Sedimentary Geology (SEPM).
Larry Ward, Jackson Estuarine Laboratory, University of New Hampshire [, +1-603-862-5132]
A number of extensive, high-resolution studies examining the sedimentology and stratigraphy of the estuaries and inner shelf environments in the Gulf of Maine and adjacent areas have been conducted. As a result, advances in the understanding of nearshore deposits and controlling processes are emerging. The purpose of this session is to highlight that work. Although the results of recent studies are sought, papers synthesizing work that furthers an understanding of general depositional environments and large scale controls are welcome. Also, papers reviewing work supported by the Minerals Management Service are strongly encouraged.
9. New Insights in Atlantic Continental Margin Processes.
Sponsored by the Eastern Section of the Society for Sedimentary Geology (SEPM).
Joel Johnson, University of New Hampshire [, +1-603-862-4080]
Jim Gardner, Center for Coastal and Ocean Mapping, University of New Hampshire [, +1-603-862-3473]
Studies of the U.S. Atlantic continental margin extend back almost to the beginning of modern marine geology. In fact, the term continental margin was coined from early studies of the U.S. Atlantic margin. Recently, an increase in research of the U.S. Atlantic margin has focused on new techniques, including drilling, 3-D high-resolution seismic-reflection profiling, and multibeam mapping, that have shown a new level of complexity to the margin. We invite papers that present these new insights in depositional processes, stratigraphic history, and margin evolution.
10. Geologic Records of Biotic Change.
Sponsored by the Eastern Section of the Society for Sedimentary Geology (SEPM).
Will Clyde, University of New Hampshire [, +1-603-862-3148]
The geological record preserves the only empirical evidence of how the biosphere changed over long time scales. This session welcomes contributions that utilize innovative stratigraphic, geochronologic, and paleontologic approaches to investigate the causes and effects of past biological change. Presentations that integrate geological evidence to evaluate the relationship between biotic, climatic, and tectonic change are particularly encouraged.
11. Teleconnecting Paleobasins Using Stratigraphic and Paleontological Approaches for High Resolution Intra- and Inter-basin Correlations.
Sponsored by the Eastern Section of the Society for Sedimentary Geology (SEPM).
Sean Cornell, Shippensburg University [ , +1-315-229-5236]
Diane Burns, St. Lawrence University [, +1-315-229-5248]
Alex Bartholomew, SUNY New Paltz [ , +1-518-388-6770]
The widespread implementation of modern stratigraphic techniques, including sequence stratigraphy, event stratigraphy, and chemostratigraphy, coupled with a range of quantitative paleontologic analyses have enabled geoscientists to revisit and/or establish new higher-order correlations both within and between depocentral basins. The increased resolution of these new stratigraphic syntheses allows for a more refined analysis of spatial and temporal changes in both the environments and biotas within regional and subregional basins. In most cases, these analyses suggest that the processes driving environmental and biotic transitions in local to regional settings may indeed be connected to coeval transitions elsewhere. Ultimately, these changes may be tied to a range of processes active outside the immediate basin and perhaps even on a global scale. This session will encourage submission of research that delves into the application of various high-resolution analyses in intra and inter basinal studies. Research topics can range from establishing local geochronologies to the construction of more regional stratigraphic syntheses that have over-arching implications for regional to global processes.
12. Atmospheric–Earth Surface Interactions: Solid, Liquid, and Gas.
Rob Griffin, University of New Hampshire and Climate Change Research Center [7 January, 2010", "edu"); // End --> , +1-603-862-2021]
This session will focus on interactions between the atmosphere and various aspects of Earth's surface. Relevant topics could include, but are not limited to, air-sea exchange (gases and particles), surficial weathering, dry and wet deposition of atmospheric trace species, climate effects on the hydrologic cycle, and emissions of trace gases from terrestrial ecosystems. Field-based, laboratory-based, and theoretical investigations are all welcome.

13. Glacial and Paraglacial Coastal Systems.
Sponsored by the Eastern Section of the Society for Sedimentary Geology (SEPM)
Dan Belknap, University of Maine [, +1-207-581-2159]
Duncan Fitzgerald, Boston University [, +1-617-353-2530]
We seek papers from modern glaciated coasts, as well as formerly glaciated coasts and coasts influenced by glacial systems (thus, paraglacial). In New England and other cool-temperate regions, the signature of former glaciations is paramount in the Holocene evolution of coastal systems. Formerly glaciated coasts may be controlled by glacially eroded landscapes. Glacial sources of fine and coarse-grained sediment dominate open coastal systems, while fine-grained glaciomarine deposits may dominate estuarine settings. The morphology and distribution of sources help control morphodynamic responses and rates of change. Glacio-isostatic responses create complex relative sea-level curves. Study of these complex and highly variable coasts is important to understanding land use, geohazards, and the fundamental processes of coastal morphodynamics, sedimentology, and stratigraphy.
14. Contaminants in Groundwater–Surface Water Systems: Sources, Pathways, and Toxicities.
Rudi Hon, Boston College [, +1-617-552-3656]
Joe Ayotte, U.S. Geological Survey [, +1-603-226-7810]
Bill Brandon, EPA-Boston [, +1-617-918-1391]
Numerous natural and anthropogenic contaminants in natural waters present an increasing concern to humans regarding water quality and aquatic habitats. Contributions on subjects of arsenic, uranium, mercury, salinization by deicers, and other contaminants in various geologic settings, from characterization to fate and transport, including their transport as dissolved species or as nanoparticles, are strongly encouraged. In addition, topics on toxicities and threats to aqueous habitats are considered essential. We anticipate multiple sessions, both oral and poster.
15. Characterization and Remediation of Contaminated Bedrock Aquifers.
Nancy Kinner, University of New Hampshire, Civil/Environmental Engineering [ , +1-603-862-1422]
Many New England communities use water derived from bedrock aquifers as a potable supply. Previously, when contamination of these aquifers occurred, an alternative water supply was often the solution because of the difficulty in characterizing the scope of the problem and remediating it with available technologies. Indeed, until recently, little was known about the biogeochemistry of bedrock aquifers, and detection and tracking of contaminants in them was nearly impossible without huge expenditures, if at all. This session will explore recent developments in hydrogeologic, geophysical, and biogeochemical characterization of contaminated bedrock aquifers and the use of these tools in planning and implementing remediation strategies.
16. Treated Wastewater and Urban and Suburban Runoff as Aquifer Recharge: Issues for Protection of Groundwater Quality.
Denis R. LeBlanc, U.S. Geological Survey, Northborough, Mass. [, +1-508-490-5030]
There is considerable interest, even in the humid Northeast, in the recharge of treated wastewater and urban and suburban runoff to maintain groundwater levels and baseflow to streams in hydrologically stressed basins. Municipal and community wastewater treatment facilities are increasingly being required to discharge treated water to the ground through infiltration basins or leaching fields rather than directly to streams. Low-impact development designs are being required in new developments to recharge runoff locally rather than transporting runoff offsite through collection systems. There are concerns, however, about the long-term effects on groundwater quality of the recharged water because of nutrient and organic loads, trace organics such as PAHs, and other emerging contaminants. This session will focus on field studies of these water-quality effects, including the nature and types of contaminants from these recharge sources, the transport and persistence of the contaminants in the subsurface, and natural restoration of groundwater contaminated by recharge from wastewater and runoff.
17. Glacial and Postglacial Environments on the Frontier: Quaternary Studies in the New England–Canadian Border Region.
Woody Thompson, Maine Geological Survey [, +1-207-287-2211]
P. Thompson Davis, Bentley College [, +1-781-891-3479]
Brian Fowler, Fowler Management Resources [, +1-603-524-8969]
This session will focus on glacial and climatic events in northern New England, along with neighboring Quebec, New Brunswick, and northeastern New York. Topics may include the sequence and chronology of glaciations and ice retreat, and the relation of glacial events to climate oscillations in the North Atlantic region. Age determinations for these events and correlations with the New England varve chronology will also be discussed.
18. Advances in Paleoclimate from the Terrestrial Realm to the Deep Sea.
Amy Frappier, Boston College [, +1-617-552-1296]
Jon Woodruff, Woods Hole Oceanographic Institution [, +1-508-289-3437]
Proxy records of past environmental change provide critical hindsight for assessing current trends and projecting future environmental conditions. We invite papers presenting new paleoclimate records and techniques from terrestrial and aquatic depositional environments, including lacustrine, spelean, wetland, fluvial, and marine deposits as well as tree-ring, coralline, molluscan, microfossil, and other biologic archives. Studies of modern processes and past environmental changes (Recent, Quaternary, and deep time) are welcome, especially those investigating new techniques, high-resolution or multi-proxy records, and/or multiple sites.
19. Earthquakes and Volcanoes — Past, Present, and Future, Regional and Global.
Jeffrey B. Johnson, University of New Hampshire, Earth Sciences [, +1-603-862-0711]
Pedro de Alba, University of New Hampshire, Civil Engineering [, +1-603-862-1417]
Research groups in the northeast are focused on local, regional, and global seismicity as well as active and extinct volcanoes. We seek to convene a diverse session related to the understanding of the causes of East Coast earthquakes, the implications for hazard mitigation, and the interpretation of teleseisms recorded locally. We also wish to involve scientists who monitor active eruptive processes. Theoretical and field/lab-based studies of earthquake physics and eruption dynamics are particularly encouraged in this session.
20. Mineral Properties: Geochemical, Petrological, and Environmental Applications.
Bruce Watson, RPI [, +1-518-276-8838]
Jonathan Price, RPI [, +1-518-276-6000]
This session will focus on mineralogical investigations applied to the understanding of geochemical phenomena ranging from petrological to environmental in nature. The intent is to bring together researchers with a common interest in characterization of specific mineral properties, including chemical variations, stability, solubility, and kinetic behavior. Contributions from both field- and laboratory-based researchers are encouraged.
21. Elemental Cycling within Terrestrial Environments.
Julie Bryce, University of New Hampshire [, +1-603-862-3139]
Scott Bailey, USDA Forest Service, NE Research Station and Center for the Environment [, +1-603-535-3262]
Kevin McGuire, Plymouth State University [, +1-603-535-3250]
Steve Kahl, Plymouth State University, Center for the Environment [, +1-603-535-3154]
For this session, we seek contributions on applications of trace element and/or isotope geochemical techniques to quantify processes within terrestrial watersheds and ecosystems. We welcome field-based or experimental approaches to outstanding problems in biogeochemistry, hydrogeology, and environmental geochemistry.
22. Innovative Teaching Methods in the Earth Sciences (Posters).
Frank Revetta, SUNY-Potsdam [, +1-315-267-2289]
This session provides the opportunity for teachers at all levels to share their innovative and creative methods for teaching concepts in the earth science to K-12 students.
23. Health and Geology in the Northeast.
Co-sponsored by GSA Geology and Health Division.
Catherine Skinner, Yale University [, +1-203-432-3787]
Nelson Eby, University of Massachusetts-Lowell [, +1-978-934-3907]
This session will focus on the relationship between geological factors (both natural and anthropogenic) and disease, pathology and death in modern and fossil humans, animals and plants. This is an eclectic field and the intent of the session is to bring together researchers with various backgrounds and interests in order to facilitate discussion of the interrelationships between geology and health.
24. History of Geological Ideas and Understanding of the Northern Appalachians.
Sponsored by GSA History of Geology Division.
William R. Brice, University of Pittsburgh-Johnstown [, +1-814-269-3950]
This session will focus on our understanding and interpretation of the geology of the northern Appalachian Mountains and on the people who developed these ideas.
25. Google Earth Science: Geological Applications of Interactive Web-Based Maps.
Declan G. De Paor, Worcester Polytechnic Institute [, +1-508-831-5116]
Steve Whitmeyer, James Mason University [, +1-540-568-7119]
In 2005, Google Inc. launched the revolutionary map service called Google Earth™. Building on previous Keyhole™ technology, it permits ordinary web-users to study the planet with a sophistication previously available only on high-end graphics workstations. Other services quickly followed, including MSN Virtual Earth™, NASA World Wind, Earth Browser, Zoomify™, etc. This theme session will showcase earth science applications of Google Earth or equivalent web-based mapping software. Appropriate topics would include direct viewing of geomorphic features on Google Earth, draping of geological data layers, virtual field trips, lesson plans, etc. The aim is to bring together early adopters in all aspects of the geosciences and encourage brainstorming.
