During the 2010-11 Antarctic field season the UNAVCO polar group supported an unprecedented 33 individual PI-based science campaign projects. One hundred twenty receivers and 28,000 pounds of supporting gear was sent to the continent for campaign support, including thirty five new NetR9 systems and twelve netR8's. Nineteen of the NetR9 receivers remain on the ice to support long term data collection at the Whillans Ice stream (WISSARD) and the Byrd Glacier. The WISSARD project also deployed a third continuous site with Iridium comms this season, bringing the total telemetered stations to three for that project. A continuously operating GPS station with Iridium comms was installed on the Ross Ice Shelf for the ANDRILL project in an area known as Coulman High. This site is transmitting valuable information about the behavior of the ice shelf near the grounding line.
The WAIS Divide site was rebuilt this season after failing late last year. 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 B-426, McKnight B-421, Fountain B-425). Six teams were supported in the central Transantarctic Mountains near the Beardmore glacier as part of a multidiscipline effort in the region.
This season saw expanding interest in UNAVCO's growing suite of terrestrial LiDAR scanners and nine separate Antarctic projects were given TLS support. The instruments continue to work well in the frigid Antarctic environment. Data was collected in locations ranging from the McMurdo Dry Valleys to the top of Mount Erebus. One TLS instrument traveled aboard the icebreaker ODEN as it made its way to McMurdo Sound and was used to scan sea ice surface features in the Bellinghausen, Amundsen and Ross Seas.
