Picture of the Day for
Today, as we pulled away from ice
station “Rodin”, the ice team frantically scurried
about the ice, collecting the last cores and thickness measurements from the
piece of ice that we had called home for the last week. Other groups prepared
for getting underway in search of penguins and continued analysis of samples
already collected. Pictured here is
Kerry Claffey in the freezer van (-20ºC), preparing
some ice cores for structural analysis. The ice core is cut into sections and
melted onto glass plates. It is then planed to 2-3 mm thick. The photo on the
right shows three distinct ice types found in one 15 cm core: fine grained snow-ice
on the top, medium grained frazil in the middle, and larger grained columns of
ice at the bottom. (Photo by Paula Adkins and Kerry Claffey)
