Climate Change: Realities, Surprises and Opportunities.
Sunday, 22 March. Time to be announced.
- Sea Level and Salt Marsh Ecogeomorphology.
Cosponsored by the Eastern Section SEPM (Society for Sedimentary Geology).
Beverly Johnson, Bates College; Julia Daly, University of Maine at Farmington.
Salt marshes provide a host of important ecosystem services, such as organic matter production and nutrient cycling, coastline protection, and carbon sequestration. Yet, they are highly vulnerable to sea-level rise and climate change. This session seeks papers that use a variety of techniques to explore the interactions between sea-level rise and the physical, geological, and ecological processes within salt marshes on a variety of time scales.
- Orogenesis and Arc Collisions: From Models to Observations of Modern and Ancient Orogens.
Tim Byrne, University of Connecticut; Cees van Staal, Geological Survey of Canada; Peter Koons, University of Maine.
Arc collisions have contributed to orogenic processes since the early history of plate tectonics on Earth, and geologists have appreciated their importance in the construction of continental crust for several decades. The complexities associated with arc collisions, however, have only recently been recognized as numerical and analytical models have been integrated with detailed studies of the temporal and spatial evolution of specific orogens. For example, the feedback between erosion, exhumation, metamorphism, and atmospheric processes has only recently been recognized, and the links between preexisting crustal-scale heterogeneities and orogenic processes appear to be fundamental to the orogen kinematics and dynamics. Finally, the relation between surface-lithosphere dynamics in collisions is a developing field of research. To better understand the role of arc collisions in orogenesis, we invite papers from a range of disciplines and field areas. Oral and posters.
- Aspects of Transatlantic Research on Magma Systems.
David Gibson, University of Maine at Farmington; Dan Lux, University of Maine; Martin Feely, National University of Ireland.
This session aims to bring together geologists from both sides of the Atlantic to exchange current ideas on integrated research on magma systems. Aspects of research include, but are not limited to, timing of igneous activity, pluton emplacement and assembly, magma sources in differing tectonic settings, crystallization history in magma chambers, post-crystallization mineralization studies, and the role of magmatism in crustal growth. In addition, we hope to organize an accompanying poster session where students can present their research on these topics.
- Climatic Change: Perspectives and Insights from Hothouse and Icehouse Climates in Deep Time.
Cosponsored by the Paleontological Society.
David Sunderlin, Lafayette College; Kira Lawrence, Lafayette College.
Because the instrument-produced record of climatic variations is short relative to the time scales on which many climate system processes operate, understanding the dynamics and effects of recent and future climate change requires a deep time perspective. Paleobiological and biogeochemical information in the terrestrial and marine stratigraphic record provide data for examining pre-Quaternary climate conditions and their variability at both local and global scales. We seek to convene a diverse session broadly encompassing studies that explore climate signatures preserved in the ancient biosphere and geologic record as well as the context those signatures provide for recent climate change. We invite papers that explore case studies in paleoclimatic analysis as well as those that consider new methodological approaches to the study of deep time climates.
- Modern Glacial Processes and the Glacial Sedimentary Record: In Honor of Joe Hartshorn. Cosponsored by the Eastern Section SEPM (Society for Sedimentary Geology).
Carl Koteff, U.S. Geological Survey; Tom Weddle, Maine Geological Survey; Michael J. Retelle, Bates College.
This symposium focuses on studies of modern glacial processes and implications for the glacial stratigraphic record. We are holding the session in honor of Joseph H. Hartshorn, friend, colleague, and mentor who passed away on 5 May 2008. After returning to the United States as a decorated Lancaster bomber pilot in World War II, Joe earned his Ph.D. in geology at Harvard, specializing in geomorphology. His keen perception of landscapes and landforms was put to use by the U.S. Geological Survey mapping glacial and Quaternary deposits in New England. Joe's experience in New England was greatly enriched by field work and excursions in modern glacial settings in Alaska, Greenland, Iceland, and Ellesmere Island. When Joe changed careers and brought his deep experience of the modern environments, field mapping, and stratigraphy to the University of Massachusetts, his teaching reached many, from introductory students to those with doctorates. We rest assured that his students still ponder some of the questions on terraces, two tills, and Dirt Machines that Joe planted as seeds in his lectures and at the outcrop.
- Lakes and Environmental Change.
Brad Hubeny, Salem State College; Lisa Doner, Plymouth State University.
Lakes are sensitive to changing environmental conditions, and accumulated sediments can preserve high-resolution records of this variability. Such environmental change can result from a variety of forcings at a variety of timescales. This session welcomes all contributions associated with lake responses to and sedimentary records of environmental change at any time scale. Studies associated with developing or refining proxies are especially encouraged.
- Provenance and Orogenic History of Ganderia: Key Element in the Mid-Paleozoic Accretionary History of the Appalachian Orogen.
Sandra Barr, Acadia University; Cees van Staal, Geological Survey of Canada.
Provenance and orogenic history of Ganderia are key elements in the Mid Paleozoic accretionary history of the Appalachian orogen. Ganderia, a composite peri-Gondwanan domain, forms a large part of at the least the northern Appalachian orogen. This session will focus on where Ganderia came from, its defining characteristics, the nature of its basement, and how it interacted with other Appalachian elements during the construction of the orogen.
- The Boston Basin and Beyond: In Honor of Margaret D. Thompson.
Jean Crespi, University of Connecticut; Cathy Summa, Winona State University.
This session is in honor of Margaret D. Thompson's career as a mentor and scientist. We seek talks on (1) the Neoproterozoic and Paleozoic history of the Boston Basin and broadly related aspects of Appalachian paleogeography and Acadian/neo-Acadian orogenesis; (2) topics of general scientific interest by former students of Meg Thompson; and (3) the importance of undergraduate research and mentoring in motivating students to pursue careers in geoscience. Meg has advanced understanding of the tectonics of southeastern New England through careful combination of stratigraphic, paleomagnetic, and geochronologic analyses. Contributions that highlight multidisciplinary and collaborative approaches to scientific research are especially welcome.
- Maine Groundwater: Sustainable Aquifer Use through Monitoring and Regulation.
Robert Marvinney, Maine Geological Survey; Carol White, C.A. White & Associates.
This session will cover four topics: (1) the characteristics of Maine water resources; (2) site-specific examples of detailed hydrogeologic analyses used in permitting and monitoring; (3) an overview of Maine's regulations that protect groundwater and dependent resources while allowing sustainable withdrawals; and (4) the value of groundwater to Maine's economy.
- Natural Hazards: Supporting Mitigation to Avoid Future Costs.
Laurence Becker, Vermont Geological Survey.
Many natural hazards affecting northeastern North America have a foundation in geology: landslides, earthquakes, coastal erosion, fluvial erosion, and flooding. This session will cover a broad spectrum of hazards and will address the many contributions geologic mapping and research make to understanding and avoiding the impacts of these hazards.
- Mineral Resources of the Northeastern United States and Eastern Canada.
William Kelly, New York State Museum-New York State Geological Survey; Marian Lupulescu, New York State Museum-New York State Geological Survey.
- Geologic Maps as Tools for Resource and Environmental Issues (Posters).
Robert G. Marvinney, Maine Geological Survey.
Geologic maps are essential tools for land use and management decisions of all kinds, from the analysis of water resources to mineral resources and geologic hazards. This poster session seeks contributions from all sectors that highlight the role of basic geologic maps, and specialized maps derived from them, toward addressing important societal issues.
- From Road Salt to Arsenic and Other Environmental Contaminants in Hydrologic Systems.
Rudi Hon, Boston College; Bill Brandon, U.S. Environmental Protection Agency; Joseph Ayotte, U.S. Geological Survey.
Environmental contaminants in both groundwaters and surface waters are a concern to researchers, regulatory agencies, health organizations, public policy groups, and to the general public as well. We seek a spectrum of presentations that focus either on a single aspect of environmental contamination or are cross-disciplinary, involving several subdisciplines of interest to a wider group of professions.
- GIS Applications in Geoscience Teaching, Research, and Map Production.
Dykstra Eusden, Bates College; Mark Swanson, University of Southern Maine.
The explosion of new GIS methods courses in the geoscience curriculum and the dramatic increase in the use of GIS by researchers in state, federal, private, and academic settings have led to a wealth of new geologic applications in digital technology. The purpose of this session is to showcase (1) the wide variety of digital GIS methods used in geoscience research; (2) new teaching pedagogies used in developing GIS-based courses; and (3) the wide range of digital GIS-based maps being produced by geologists. This session seeks contributions from geoscientists in academia, the private sector, and government agencies who use and/or teach about GIS. Undergraduate and graduate students doing research using GIS methods as a major focus of their study are also strongly encouraged to submit an abstract. Users of any type of GIS platform are encouraged to submit (i.e., not just ArcGIS but also Google Earth and others). Oral presentations will focus on teaching pedagogies used in GIS, new GIS methods in research, and strategies for the use and production of GIS-based maps. Poster presentations will focus on specific research projects that use GIS and that are amendable to that style of presentation.
- Remote Sensing Applications to Geomorphology.
Patrick A. Burkhart, Missing Affiliation; Jack Livingston, Slippery Rock State University.
LIDAR and other remote sensing technologies provide an unprecedented opportunity to investigate landforms and landscapes. Please submit recent discoveries that reveal the power of these developments for the study of geomorphic systems.
- Geoarchaeology: Sites, Substrate, Sources, and Context.
Cosponsored by the Eastern Section SEPM (Society for Sedimentary Geology).
Alice R. Kelley, University of Maine; Allen Gontz, University of Massachusetts-Boston.
Geoarchaeology is a diverse field that combines techniques from geology and archaeology to better understand human societies, culture, and their environment. This session welcomes oral and poster presentations that address terrestrial and underwater geoarchaeological methods, sites, geological resources, or other uses of geology to address archaeological questions.
- Glacial and Paraglacial Coasts: Stratigraphy, Processes, and Geomorphology. Cosponsored by the Eastern Section SEPM (Society for Sedimentary Geology).
Dan Belknap, University of Maine.
Glaciated coasts, past and present, comprise a diverse mix of processes and environments affected by glacial landforms, sediment sources, and isostatically influenced sea-level changes. Coastal landscapes of the northeastern U.S. and Canadian Maritimes are profoundly influenced by glacial history, as are many other populated regions around the world.
- Rheology, Kinematics, and Strain Localization in Faults and Shear Zones.
Scott Johnson, University of Maine; Michael Williams, University of Massachusetts-Amherst; Christopher Gerbi, University of Maine.
We are seeking presentations on the topics of strain localization, kinematic analysis, and rheological evolution in zones of high strain spanning the upper to lower continental crust. Papers from the northeastern Appalachians as well as those from other orogenic belts and plate boundaries are encouraged. If you or your collaborators or students have been evaluating rheological variation in space and time, the amounts and distributions of kinematic quantities like vorticity, and the distribution and magnitude of strain, we encourage you to submit an abstract. We are particularly interested in hearing from workers who have conducted multidisciplinary studies — for example, combining structural geology and petrology to better understand chemical-mechanical coupling leading to localization or-for another example — those who have combined natural observations with numerical or analog modeling experiments. Broadly structural-tectonic in context, 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.
- Advances in Stratigraphy and Paleontology of Paleozoic Dark Shales.
Cosponsored by the Paleontological Society.
Alex Bartholomew, SUNY-New Paltz; Diana Boyer, SUNY-Oswego.
Amongst the vast array of paleoenvironments preserved in the rock record, dysoxic to anoxic, shale-dominated facies remain some of the most poorly understood. At the same time, these rocks preserve many resources that have recently become economically attractive. Recent investigations into a broad spectrum of shallow- to deep-water, low oxygen paleoenvironments have brought about a much better understanding of processes that dominated ecology and deposition in this important suite of sedimentary facies.
- Bioevents, Tectonics, and Sea-Level Change in Marine to Non-Marine Strata of Northeastern North America.
Cosponsored by the Paleontological Society.
Sean Cornell, Shippensburg University; Patrick McLaughlin, Wisconsin Geological Survey.
In recent years, the Paleozoic marine to non-marine intervals of eastern North America are being reexamined from the perspective of paleontology, event stratigraphy, sequence stratigraphy, etc. These analyses are shedding significant insight into multiple types of biotic events and a range of environmental disturbances, especially within the Ordovician through Devonian succession. These studies are also contributing to the understanding of tectonic events and the timing of tectonism within the Paleozoic of eastern Laurentia. An increasing number of studies show that the stratigraphic record is punctuated by environmental disturbances on multiple spatial and temporal scales. These disturbances evidently had significant yet differing degrees of impact on marine and non-marine organisms, and they have been attributed to fluctuations in sea level, climate, sea water chemistry, primary productivity, etc. Nonetheless, the linkages between each disturbance event and their specific effect on marine and non-marine floras and faunas are challenging to unravel. This session will focus on highlighting the range of approaches used to explore critical environmental, biotic, and tectonic changes during this time interval in order to demonstrate the major strides that have been made.
- Habitat Restoration in North Atlantic Watersheds.
Karen Wilson, Univ. of Southern Maine; Noah P. Snyder, Boston College ; Ellen Douglas, University of Massachusetts.
- Land Conservation and Management Strategies for Protecting Water Quality.
David Hart, Senator George J. Mitchell Center for Environmental & Watershed Research, University of Maine.
The first part of this session will examine watershed-level water quality protection strategies. In New England, water quality and point-source protection is generally pursued by three distinct constituencies: water district professionals, non-governmental organizations, and government. A proliferation of sometimes competing state mandates and an absence of uniform information and expectations has resulted in a patchwork of protection and management strategies that often lack watershed-wide cohesion. We will first explore best practices for supporting comprehensive watershed-level protection strategies and implementation. The second part of this session will examine community-based conservation models as management tools. Community-based research has become a continuum that ranges from a top-down citizen science–participant methodology to a bottom-up collaboration between community members and a variety of stakeholders. We will look at how these programs affect the environment, the stakeholders, the community, local governments, and future policy decisions. What makes a program successful; how is success defined; and how can it be replicated and/or sustained?
- Using Monitoring Data to Influence Management and Conservation of Aquatic Ecosystems.
Tom Danielson, Maine Dept. of Environmental Protection-Bureau of Land and Water Quality.
This session will focus on the importance of using monitoring data to inform and improve the management and conservation of aquatic ecosystems. This session will provide examples of well-designed integration of sound science into management decisions leading to tangible improvements in aquatic ecosystems. Large or long-term studies, in particular, can be difficult to sustain, but can provide invaluable information to base difficult management decisions. In other cases, discrete datasets can be the basis of good management decisions or can be used to determine if previous decisions led to desired environmental results.
- Competitive Demands for Groundwater Resources in the Northeast.
Martha Nielsen, USGS–Maine Water Science Center.
- State of Maine’s Environment.
John Peckenham, Senator George J. Mitchell Center for Environmental & Watershed Research, University of Maine.
This session highlights ongoing water-related research in Maine, including presentations on the consequences of climate change on water resources, practices for restoring the quality of Maine’s urban impaired streams, and a comparison of brook trout populations in Maine’s lakes and streams from a regional perspective.
- Chemical, Biological, Hydrological, and Geochemical Aspects of Surface Waters and Groundwaters and Their Policy and Economic Implications (Posters).
Ruth Hallsworth, University of Maine.
This session includes submission of abstracts for the Maine Water Conference juried student poster competitions. The abstract should state clearly that it is a student submission and reference the judging category (high school, undergraduate, graduate). Abstracts for this session will address one or more aspects of water quality or quantity issues. These may include chemical, biological, hydrological, and geochemical aspects of surface- and groundwaters and their policy and economic implications.
