Antarctic Research (SCAR) and convened the Scientific Research Program on Sub-glacial Antarctic Lake Environments (SALE). Dr. Priscu earned his Ph.D. in microbial ecology in 1982 from the University of California at Davis.

Rosanne D’Arrigo is a Lamont Research Professor at the Tree-Ring Laboratory of the Lamont-Doherty Earth Observatory (LDEO) in Palisades, New York. She is also the Associate Director of the Biology and Paleoenvironment Division at LDEO. Her field of study is dendrochronology, specifically the development and analysis of paleoclimatic reconstructions based on tree-ring data. Her research interests include the generation of large-scale reconstructions of Northern Hemisphere temperatures, analysis of the “divergence problem” in tree-ring records from northern latitudes, and the reconstruction of the climate dynamics of Monsoon Asia. Dr. D’Arrigo received her Ph.D. in Geological Sciences from Columbia University in 1989.

Hugh W. Ducklow is the Director of the Ecosystems Center at the Marine Biological Laboratory. Dr. Ducklow is a biological oceanographer and has been studying the dynamics of plankton foodwebs in estuaries, the coastal ocean, and the open sea since 1980. He and his students have worked principally on microbial foodwebs and the role of heterotrophic bacteria in the marine carbon cycle. Dr. Ducklow has participated in oceanographic cruises in Chesapeake Bay, the western North Atlantic Ocean, the Bermuda and Hawaii Time Series stations, the Black Sea, the Arabian Sea, the Ross Sea, the Southern Ocean, the Equatorial Pacific, and the Great Barrier Reef. Much of the work was done in the decade-long Joint Global Ocean Flux Study (JGOFS), which he led in the late 1990s. He has been working on various projects in Antarctica since 1994. Currently, Dr. Ducklow leads the Palmer Antarctica Long Term Ecological Research Project on the west Antarctic Peninsula, where he is investigating the responses of the marine ecosystem to rapid climate warming. Although his research is primarily experimental and observational, he utilizes mathematical models and collaborates with modelers to gain deeper understanding and derive maximum benefit from the data we collect. Dr. Ducklow received his PhD from Harvard University in 1977.
