Research Objectives:
The zooplankton component of the Long Term Ecological Research (LTER) project is concerned with investigating and defining seasonal scale processes in krill demography and distribution in relation to the abiotic and biotic environment.
|
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 travel by Zodiac inflatable boats to local sampling stations. In the lab, the group will perform process-level experimental research on antarctic krill (ingestion, growth).
During the science cruise (LMG 03-01) they will deploy a variety of nets at LTER grid stations to collect zooplankton, including antarctic krill and fish larvae. Bioacoustic surveys will be conducted with a towed BioSonics 120 kHz transducer to document spatial patterns in krill distribution. Other studies of the growth and spawning behavior of antarctic krill will be conducted in the vessel aquarium room.
