GSA2015 ANNUAL MEETING & EXPOSITION
This session seeks to highlight recent advances in the study of
karst systems, with emphasis on process studies, method develop-
ment, modeling advances, instrumentation innovations, long-
term monitoring, and more.
T121. New Perspectives in Karst Geomicrobiology and Redox
Geochemistry: Advances from 20 Years of Interdisciplinary
Research and Exploring Our Future Frontiers
Disciplines: Karst; Geomicrobiology; Geochemistry
Advocates: Annette Summers Engel; John R. Spear; Sarah K.
Carmichael; Hazel A. Barton; Philip C. Bennett
Twenty years after the Karst Waters Institute–sponsored
symposium, “Breakthroughs in Karst Geomicrobiology and
Redox Geochemistry,” we welcome contributions that highlight
major achievements and latest advances in karst research.
Interdisciplinary participation is encouraged.
T122. Remote Sensing and Geophysical Imaging in Karst
Disciplines: Karst; Geophysics/Geodynamics
Advocates: Lewis Land; Daniel H. Doctor
Geophysics and remote sensing tools are frequently used for
investigations of karst phenomena. We welcome papers that
address the use of remote sensing and geophysical imaging in karst
regions, including both airborne and ground-based methods.
Limnogeology
T123. Carbon Cycling in Lakes
Disciplines: Limnogeology; Geochemistry; Sediments, Clastic
Advocates: Johan C. Varekamp; Amy Myrbo
Lakes cycle carbon through photosynthesis or as depocenters
for terrestrial particulate carbon. We seek abstracts that deal with
carbon inputs, outputs, or cycling processes in lakes. We have a
special interest in lakes with a volcanic or geothermal carbon input. Integrating the Past and Present to Inform the Future
T124. Hot or Cold, Wet or Dry: The Diachroneity of Late
Pleistocene and Holocene Lacustrine Climate Events
Disciplines: Limnogeology; Paleoclimatology/Paleoceanography;
Quaternary Geology
Advocates: Scott W. Starratt; Michelle F. Goman
Climate events (e.g., the YD and MCA) are identified at
numerous sites across North America, but their timing varies with
local conditions. Using a range of lacustrine proxies, this session
focuses on the reasons for this variability.
T125. Lakes of the World
Disciplines: Limnogeology; Sediments, Clastic; Geochemistry
Advocates: Scott W. Starratt; Johan C. Varekamp
“Lakes of the world” celebrates lake science for and from a
worldwide audience. Lakes are important fresh water reservoirs
and their sediments contain records of global change, pollution,
and ecological successions.

T126. Bathymetric Analysis of Axial Seamount’s Southeastern
Flank, Juan de Fuca Ridge (Posters)
Disciplines: Marine/Coastal Science; Volcanology
Advocate: Anna DeGeorge
The bathymetry of the southeastern flank of Axial Seamount
was analyzed for the purpose of better understanding the
dynamic morphology of underwater volcanoes molded by basaltic
eruptions over time.
T127. Continental Shelf and Estuarine Seafloor Mapping and
Shallow Stratigraphy on the North American East Coast
Disciplines: Marine/Coastal Science; Geomorphology;
Quaternary Geology
Advocates: Joseph Kelley; Laura Brothers
This session focuses on seafloor mapping using geophysical
remote sensing tools, supported by groundtruth observations to
provide new insights into processes acting on the East Coast shelf
and in estuaries, and the resulting stratigraphy.
T128. Field and Modeling Approaches to Understanding
the Response of Coupled Barrier-Backbarrier Systems to
Coastal Change
Disciplines: Marine/Coastal Science; Geomorphology;
Sediments, Clastic
Advocates: Christopher J. Hein; Jorge Lorenzo Trueba
This session encourages papers on field modeling and inte-
grated studies of barrier-backbarrier evolution as coupled,
dynamic systems in response to sea-level and climate change over
the Holocene and future projections.
T129. Forecasting the Coastal Response to Sea-Level Rise:
Disciplines: Marine/Coastal Science; Quaternary Geology;
Paleoclimatology/Paleoceanography
Advocates: Erika E. Lentz; Benjamin T. Gutierrez;
Simon E. Engelhart
This multidisciplinary session examines new observation and
modeling research exploring the response to sea-level rise across
coastal landscapes over a variety of timescales, and includes
examples of decision support applications for management.
T130. Sediment Transport Processes and Patterns on the
Inner Continental Shelf
Disciplines: Marine/Coastal Science; Sediments, Clastic
Advocates: E. Robert Thieler; George Voulgaris
Sediment transport in inner shelf environments occurs on a
variety of timescales and can generate distinct sedimentary
records. We seek field, laboratory, or modeling contributions that
explore storm-event to millennial-scale forcing and response.
