Palmer Long-Term Ecological Research (PAL-LTER) started in 1990 to address the hypothesis that the annual sea ice cycle may be the major determinant of spatial/temporal changes in the structure and function of Antarctic marine communities. Research now includes bacteria, viruses, phytoplankton, krill, macrozooplankton, penguins, seabirds, and marine mammals. The PAL-LTER model traces the effects of changing climate, and the extent, duration, and seasonality of sea ice on ecosystem composition and dynamics in the Western Antarctic Peninsula, where satellite observations over the past 35 years indicate the average duration of sea ice cover is now about 90 days shorter. Six collaborative projects deploy on January’s ARSV Laurence M. Gould cruise and/or to Palmer Station. Team members use airborne and underwater vehicles, moorings, numerical modeling, oceanographic cruises, and environmental sampling to address core hypotheses.

Field Season Overview

One component of the C-019 science team will sail on the January to mid-February cruise aboard the ARSV Laurence M. Gould (LMG) to the LTER research grid west of the Antarctic Peninsula. The team will use a variety of techniques while at sea including net and acoustic tows, CTD casts, Slocum gliders, and other profiling sensors.

The other component will be based at Palmer Station from October through March. The team’s main research objectives while at Palmer Station are to: (1) maintain the Palmer phytoplankton time series measurements at LTER stations B and E; (2) launch of two gliders; (3) define temperature impact on overall community ecology and physiology of phytoplankton populations collected from stations B and E; and, (4) continue to conduct several videoconferences with classrooms and other groups as part of the LTER mandated educational outreach effort.
