A “mass balance” station will be established on the sea ice of McMurdo Sound in July 2017. A hole will be drilled through 1m thick ice and a temperature probe will be inserted through the ice and into the ocean in order to measure ice and ocean temperature. An acoustic sensor will record the thickness of the snow on top of the sea ice. The data will be transmitted to New Zealand on a daily basis and interpreted to help us to understand how sea ice forms throughout winter
