The cruise commenced with a series of stations at the southern end of CLIVAR/WOCE meridional section SR3, followed by work around and offshore of the former Mertz Glacier ice tongue and the Mertz Depression.

Brief description

Oceanographic measurements were collected aboard New Zealand’s National Institute for Water and Atmospheric Research (NIWA) research vessel RV Tangaroa, cruise ta1302 (i.e. NIWA cruise tan1302), from 3rd February to 13th March 2013, sailing from and returning to Wellington. The cruise commenced with a series of stations at the southern end of CLIVAR/WOCE meridional section SR3, followed by work around and offshore of the former Mertz Glacier ice tongue and the Mertz Depression. A series of stations were then taken along 150E and CLIVAR/WOCE zonal section S4, followed by a series of stations on the Campbell Plateau on the transit back to New Zealand.
