During the 2009-10 Antarctic field season, the UNAVCO polar group supported 23 individual PI-based science campaign projects. Forty five receivers were sent to the continent for campaign support, including ten NetRS systems. Nine of these NetRS receivers remain on the ice to support long term data collection at WAIS divide under the upcoming WISSARD project, including one configured to relay data back to UNAVCO via Iridium modem. Real Time Kinematic (RTK) capabilities were provided to accurately calibrate navigation control for two state of the art underwater ROV's (B-174, B-211). GPS instruments were provided for the ongoing deformation studies on Mt. Erebus (G-081) and in support of the Dry Valleys Long Term Ecological Research projects (Doran, McKnight, Fountain). Two projects were supported during the period prior to the station opening to the summer crew. Among these was one of two groups (O-400 Casano) requesting high rate base data for aircraft geo-referencing purposes. Six POLENET style continuously operating GPS systems were prepared for the LARISSA team (C-514/C515) for installation along the east side of the Antarctic Peninsula. Five of these were successfully deployed, despite difficult ice conditions. An effort was made this season to recover two continuously operating GPS stations on the Pine Island Glacier. These had been buried by two years of snowfall. One was recovered, the other found to be in a crevasse field, and not safely accessible.
This season saw heavy use of UNAVCO's terrestrial LiDAR system. The instrument has consistently proven itself a workhorse the frigid Antarctic environment. Data was collected in locations ranging from the McMurdo Dry Valleys to the top of Mount Erebus. Investigators taking advantage of the UNAVCO terrestrial LiDAR included Barrett (B-023), Doran (B-211), Lyons (B9420), McKnight (B-421), Fountain (B-425), Kyle (G-081), and Gilles (G-167).
Highlights from the season:
