Water temperature from XBT taken from research vessel Italica in the Southern Ocean and Southwest Pacific Ocean from 2012-01-13 to 2012-01-19 (NCEI Accession 0167834)

Vertical temperature profiles were taken in January 2012 from research vessel Italica during an oceanographic cruise between New Zealand and the Ross Sea in the framework of the Southern Ocean Chokepoints Italian Contribution (SOChIC) project of the Italian National Antarctic Research Programme (PNRA) using Sippican T7 Expendable Bathythermograph (XBT) with a vertical resolution of 65 cm and a maximum nominal depth of 760 m.

Ship speed lower than 15 kn allows the probe to reach about 900 m depth. The transects were completed during 6 days to provide a synoptic picture of the thermal structure of the upper Southern Ocean. A regular 15 nm spatial sampling rate was adopted across the frontal regions of the Antarctic Circumpolar Current.
