Summary

(Summary adapted from the LTER Palmer Station web site)

The Palmer LTER focuses on the pelagic marine ecosystem in the
Antarctic, and the ecological processes which link the extent of
annual pack ice to the biological dynamics of different trophic
levels. Pack ice may be a major physical factor affecting the
structure and function of polar biota. ... Interannual cycles and/or
trends in the annual extent of pack ice are hypothesized to
impact all levels of the food web, from total annual primary
production to breeding success in seabirds.

Both a regional grid 900kmx200km West of the Antartic peninsula
as well as a palmer basin grid have been established as part of
the yearly sampling strategy. An overview of the Palmer LTER
field program involves both ship cruises and station
sampling. The ship cruise frequently occurs in January to match
the penguin nesting period and covers approximately an area of
several hundred km alongshore by two hundred km offshore. The
seasonal station sampling uses zodiacs to sample a series of
stations within a 2 mile boating limit of Palmer Station and
occurs October/November through March/April in order to sample
the biologically active spring through summer months.

A cruise or a station season of DATASETS is gathered into
related groups called a STUDY. Each study is summarized in the
catalog-by-study which is comprised of a study form, a
participant list, a cruise table, an eventlog and a map. While
the cruise table gives an overview summary of cruise activities,
the eventlog is a sequential list by time of all activities
performed on board ship. Each dataset is summarized in the
catalog-by-study by a dataset form or info file. A dataset may
include one or many files.
