Purpose
Abstract The cruise M74/1b dealt with the topic of the influence of the seasonal changing monsoon on the circulation, upwelling and productivity in the Arabian Sea. The aim of the work in the Arabian Sea is a detailed investigation of the processes determining nitrogen cycling in the oxygen minimum zone and to study its susceptibility to global change and variations during the recent geological history (paleo-nitrogen-cycle). Though multibeam data and CTD data were recorded, it was not the main focus of the cruise and no further information have been provided by the responsible party.
