Abstract:

Temperature profiles of the water column, extracted from Miniaturized Temperature Data-Logger (MTL) measurements collected during the deployment of the heat flow probe in the Bellingshausen Sea, cruise PS134. The depths were calculated from winch data and have an uncertainty of ~50 m.

Keyword(s):
