Collaborative Research in IPY: Abrupt Environmental Change in the Larsen Ice Shelf System, Antarctic (LARISSA)
The goal of this collaborative project is to investigate the modern geology, glaciology, oceanography, and biology of the Larsen-B Ice Shelf system, and apply the modern system relationships to the interpretation of paleorecords (sediment cores and ice cores) of ice shelf behavior and stability. This project includes scientists and students from Montclair State University, Berkeley Geochronology Center at the University of California, Byrd Polar Research Center at Ohio State University, Colgate University, Duke University, Hamilton College, Lamont Doherty Earth Observatory of Columbia University, National Snow and Ice Data Center at the University of Colorado, SCRIPPS Institute of Oceanography, Southern Illinois University, University of Alaska, University of Hawaii, University of Houston, and international collaborators from Ghent University, Belgium, the Korean Polar Research Institute, and Loughborough University, United Kingdom.
Our first field season, cruise NBP10-01, took place during January-February 2010. Unusually thick sea ice prevented the Palmer from reaching the Larsen Ice Shelf system. We therefore shifted to back up plans. The Montclair State University group has focused its efforts on three of the back-up sites, Barilari Bay, Hugo Island Trough, and Jun Jaegyu Seamount. Barilari Bay and Hugo Island Trough provide an opportunity to examine the timing and rate of deglaciation across the western Antarctic Peninsula continental shelf. Barilari Bay is located immediately upwind of the Byrd Polar Research Center's ice core site on the Bruce Plateau, providing the opportunity to develop parallel records of atmospheric and oceanographic controls on Holocene events in the Antarctic, for example the early Holocene warmth that followed deglaciation, the middle Holocene climatic optimum, which is observed on both sides of the Peninsula, and examine whether or not a clear Little Ice Age signature exists in the Antarctica Peninsula region. Jun Jaegyu Seamount is a newly discovered seamount located in an area far from the nearest site of recent volcanic activity. MSU personnel examined the benthic organisms and geochemistry of basalts collected in a dredge samples. A second field season is planned for 2012, during which we will again attempt to access the Larsen-B embayment in order to study the long-term behavior of the Larsen Ice Shelf system and its evolution following the 2002 collapse.

Static and shock pressure treatment of synthetic Mars basalts: Implications for understanding the evolution of crustal magnetic anomalies
This project investigates the origin and subsequent modification of strongly magnetized regions on Mars via collaboration between Montclair State University, Harvard University, the University of Hawaii, and the University of Minnesota. This works builds on previous studies in which basalts were synthesized using experimental parameters that bracket the range of potential chemical compositions, oxygen fugacity, and cooling histories expected for Martian lavas. The mineralogy, mineral textures, magnetic recording assemblage, and remanence carrying properties of the run products were characterized. We found that oxygen fugacity dominated over cooling rate in controlling magnetic properties (Brachfeld and Hammer, 2006; Bowles et al., 2009). Samples synthesized at QFM buffer conditions and moderate to high cooling rates optimized TRM acquisition, displaying stable-single-domain behavior, TRM intensities up to 40-200 A/m, and possessing moderate to high Curie temperatures that imply stable magnetizations at burial depths of several 10s of km in the Martian crust. Three new lines of inquiry will be added: 1. Inclusion of a basalt composition observed by the Mars Spirit Rover at the Gusev Crater site that is consistent with global elemental abundance data provided by the Gamma Ray Spectrometer aboard the Mars Odyssey orbiter. 2. Inclusion of sulfur in the starting materials for dynamic cooling experiments to assess the partitioning of iron into ferrimagnetic oxide and sulfide minerals and subsequent effects on rock magnetic properties. 3. Application of static pressure and shock pressure treatments to these experimental run products to assess the modification of a primary TRM by impact events.
Enhancing Holocene Ice Sheet and Ice Shelf Geochronology using Geomagnetic Paleointensity Variations
The goal of this project is to measure geomagnetic inclination, declination, and intensity of remanence in the Shallow Drilling Program (SHALDRIL) Maxwell Bay sediment core. This record, collected from the South Shetland Islands, Antarctic Peninsula, possess terrigenous silty-clay lithology and a calcite-based radiocarbon chronology, which is a rare combination for Antarctic margin sedimentary records. The Maxwell Bay site will be used to generate regional reference records of geomagnetic paleosecular variation (PSV) and relative paleointensity (RPI). These geomagnetic reference curves will be applied to tune and date other Holocene paleoclimate records in the Antarctic Peninsula region that lack suitable materials for dating.
