Fieldwork


Ross Sea, Antarctica (October - November 2012)

Two field sites (Butter Point and Iceberg) were chosen to represent different first-year sea ice environments within the Ross Sea. Blowing snow collection towers were erected at each site and collected snow samples during a period of four weeks. Weather permitting, each site was visited via helicopter every other day to collect surface snow and any blowing snow captured in the baskets. Sea ice cores of nearly 2 m length were also extracted from each site.

   

In addition to the main field sites, a 10-point transect sampled surface snow perpendicular to the ice edge. This transect also included the extraction of three sea ice cores. Sea ice cores were collected at several other points around Ross Island in conjunction with colleagues measuring tropospheric halogen gas concentrations.
