Abstract:
In situ sediment temperatures measured during cruise PS134 on the Bellingshausen Sea Shelf. Five Miniaturized Temperature Data-Loggers (MTL) were mounted on a 5 m lance for measuring sediment temperatures. One MTL was mounted on the weight head (Sensor 0) and reports here the bottom water temperature.
