    String acquisition_description "Ice floes were accessed from the LMG throughout the cruise for snow and ice
studies that entailed ice and snow thickness transects, snow collections, ice
core collections and brine collections. In addition CTD deployments and
measures of bacterial and algal production were undertaken while on these long
term ice stations. Thickness transects and snow pits were accomplished in
conjunction with OG-241.
 
At the ice stations we measured ice thickness transects 20 m to 100 m in
length. These transects were often located in an area under which the divers
(BG-244) would be working. Along these transect lines we measured snow depth,
slush depth (if present), depth ofthe wicked layer (the layer of snow above
the slush layer which has absorbed moisture), ice thickness, freeboard (the
distance from sea level to the ice surface), and ice surface temperature.
 
When time and ice conditions permitted, surveys of snow depth and ice
thickness were conducted along 20 to 100-m-long lines. These survey lines were
laid out on the ice and snow depth, freeboard, and ice thickness were measured
every meter along the line. This was a team effort with individual people
working a 1 m auger, a 2 m auger, snow pits, and an ice thickness tape. Ice
cores were also taken to provide a detailed look at ice properties and
structure. These surveys were conducted at 10 sites in 2001 and are summarized
in the 2001 table. Surveys were conducted at 12 sites in 2002 and are
summarized in the 2002 table.

The Southern Ocean GLOBEC Program (SO GLOBEC) will investigate the dynamic relationship between physical processes and ecosystem responses through identification of critical parameters that affect the distribution, abundance and population dynamics of target species. The overall goals of the SO GLOBEC program are to elucidate shelf circulation processes and their effect on sea ice formation and krill distribution, and to examine the factors which govern krill survivorship and availability to higher trophic levels, including penguins, seals and whales. The focus of the U.S. contribution to the international SO GLOBEC program will be on winter processes. This component will focus on the distribution and activities of sea ice microbial communities. This will be accomplished using an integrated combination of sampling (vertical profiles, horizontal surveys, and under-ice surveys) and observational protocols. Experiments will be designed to estimate microbial activity within the sea ice and at the ice-seawater interface. The research will be coordinated with components studying the water column productivity and the sea ice habitat. The result of the integrated SO GLOBEC program will be to improve the predictability of living marine resources, especially with respect to local and global climatic shifts.";
