<p>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.

<p>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.

U.S. GLOBal ocean ECosystems dynamics
U.S. GLOBEC (GLOBal ocean ECosystems dynamics) is a research program organized by oceanographers and fisheries scientists to address the question of how global climate change may affect the abundance and production of animals in the sea.
The U.S. GLOBEC Program currently had major research efforts underway in the Georges Bank / Northwest Atlantic Region, and the Northeast Pacific (with components in the California Current and in the Coastal Gulf of Alaska). U.S. GLOBEC was a major contributor to International GLOBEC efforts in the Southern Ocean and Western Antarctic Peninsula (WAP).

<p>The fundamental objectives of United States Global Ocean Ecosystems Dynamics (U.S. GLOBEC) Program are dependent upon the cooperation of scientists from several disciplines. Physicists, biologists, and chemists must make use of data collected during U.S. GLOBEC field programs to further our understanding of the interplay of physics, biology, and chemistry. Our objectives require quantitative analysis of interdisciplinary data sets and, therefore, data must be exchanged between researchers. To extract the full scientific value, data must be made available to the scientific community on a timely basis.</p>

GLOBEC: Sea Ice Microbial Communities
<p>The U.S. Global Ocean Ecosystems Dynamics (U.S. GLOBEC) program has the goal of understanding and ultimately predicting how populations of marine animal species respond to natural and anthropogenic changes in climate. Research in the Southern Ocean (SO) indicates strong coupling between climatic processes and ecosystem dynamics via the annual formation and destruction of sea ice. 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.</p>

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 foraging behavior of adult female crabeater seals, using a combination of satellite-linked tracking, specialized diver recorders, and stable isotopic tracers. This research will be coordinated with components focused on prey (krill) distribution and the physical environment. The results will be analyzed using an optimality model. 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.</p>

<p>These observations are being analyzed in conjunction with those collected by personnel on the <em>N.B. Palmer</em> to yield a regional ice maps. The summary data from the observations on the <em>Gould</em> show substantial amounts of open water were encountered during cruise as was evident from a large amount of time spent in the vicinity of the southern end of Adelaide Island where the reoccurring polyna predominated. Because of these operations, the operations are highly biased and significant editing of observations has to occur to account for reoccurring observations in the same region. Such editing and analysis are underway. Despite these known biases, the observations yield useful information in regards to the types of ice encountered. For instance, the average estimated ice thickness on ridged ice types was 54 cm while the average level ice thickness encountered was 38 cm (below). Snow thickness estimates yielded an average snow thickness of 11 cm with only 70.8% of the ice observed had snow (the remainder of the ice observed being nilas or young gray ice with new snow cover).</p>
