Research Objectives: The bio-optical component of the Long Term Ecological Research (LTER) project focuses on the space/time variability of ecological processes. They also investigate the linkage between shipboard surface observations and satellite observations relevant to these various processes including sea ice coverage and phytoplankton biomass and production.

Field Season Overview:
Field work includes a Palmer Station program and a science cruise aboard the R/V Laurence M. Gould. During the Palmer Station program researchers will use autonomous profiling vehicles (APVs) to measure in-water bio-optical and hydrographic properties within LTER's small scale study area, 5 square kilometers around Palmer Station.

During the science cruise (LMG 03-01) they will make sea ice observations in accordance with international protocols and measure bio-optical properties using a free-fall profiling system. They make use of models and satellite data for the peninsula area including sea surface temperature, ozone concentration, cloud cover, and SEAWIFS.
