Acquisition Description:

Sea ice observations on the Southern Ocean GLOBEC cruises were conducted according to standardized protocols developed and utilized by members of the Antarctic Sea Ice Processes and Climate working group (co-sponsored by SCAR and GlOCHANT).

Routine observations of sea ice and snow characteristics were routinely collected on an hourly basis while the L.M. Gould was actively steaming throughout the cruise. These observations began on 26 July 2001 and continued through 27 August 2001. The observational protocol followed during the cruise was the protocol that is formally endorsed by the SCAR ASPeCt (Antarctic Sea ice Processes and Climate) program for observing sea ice characteristics. In short, our program (combined efforts of BG-244 as well as OG-241) was able to gather the information that will be used to characterize the predominate types of ice in the region according to parameters, such as areal coverage, floe size, ice thickness, snow type, snow thickness and deformation.
