The Arabian Sea process cruise field work focused on an area extending from the southeast coast of Oman toward India (15 °N  69 °E) and southward into the central northwestern Indian Ocean (10 °N  65 °E).   Station locations were selected with the primary goal of investigating regions of seasonal upwelling associated with the Southwest Monsoon and determining the spatial extent of the influence of this upwelling; to sample the area of the Arabian Sea experiencing intense oxygen deficiency; and to sample far enough from the anticipated upwelling to include a site with minimal wind-driven, seasonal effects.   Research cruises were scheduled in July, August and September to coincide with the Southwest Monsoon; December, January and February to coincide with the Northeast Monsoon; and March/April to study the region during an intermonsoon period.

The entire Arabian Sea Process Study effort consisted of approximately 17 cruises aboard the R/V Thomas Thompson based from Muscat, Oman.   Merged hydrographic data products have been compiled from the six process cruises summarized in the table below.   Detailed cruise reports can be displayed by selecting the info button.
