LARISSA - LARsen Ice Shelf System, Antarctica, a NSF-funded project.
We are conducting an integrated, multi-disciplinary field program to address the rapid and fundamental changes occurring in the Antarctic Peninsula region as a consequence of the abrupt collapse of the Larsen B Ice Shelf in the fall of 2002. A profound transformation in ecosystem structure and function is occurring in coastal waters of the western Weddell Sea. This transformation appears to be yielding a redistribution of energy flow between chemoautotrophic and photosynthetic production, and to be causing the rapid demise of the extraordinary seep ecosystem discovered beneath the ice shelf, providing an ideal opportunity to test fundamental paradigms in ecosystem evolution.

Meeting outside Verdemar Gym with our Punta Arenas friend, Juan Pedro Cuevas Cvetkovic, for a game of basketball.

3/8 – 3/10 -- Perhaps not everyone rubbed the brass toe of the Tierra del Fuegan. Our fuel issues have delayed our departure until the afternoon of March 11th. We have used the time for cruise planning meetings, and to have one last basketball game ashore. Pavica constructed her hula hoop, which she will use to maintain peak fitness while at sea! We had a last evening meal ashore; on our return to the ship in the evening, Commerson’s porpoises played around the ship in the moonlight, giving us a preview of the abundant marine mammals we should see at in the Southern Ocean.
