Temperature and salinity profiles collected from CTD and XBT casts from the PUERTO DESEADO in the Southern Ocean from 2009-02-17 to 2009-03-12 (NCEI Accession 0164567)
This cross-slope survey of the western South Scotia Ridge and nearby Scotia Sea consists of fifty-seven hydrographic stations. At each of these locations Conductivity/Temperature/Depth (CTD) were taken. The horizontal resolution of the upper layer thermal structure along the longest two CTD sections was highly improved with the aid of data collected from sixty Expendable Bathythermograph (XBT) probes launched at intermediate locations.

Purpose | The overarching goal of ACROSS is to better understand the causes of the observed rapid freshening and cooling of the deep water of the Antarctic Circumpolar Current as it transits the deep Scotia Sea (Figure 1). Among its objectives are to demonstrate that ventilated water from the Antarctic Slope Current of the Weddell Sea flows northward across the western section of the South Scotia Ridge east of Elephant Island, continues westward along the northern flank of the Ridge towards the Shackleton Fracture Zone, and is exported offshore and mixed with the Circumpolar Deep Water along isopycnals. The ultimate objective of the ACROSS program is to identify the optimal site and to design a cost effective long-term monitoring of the active intermediate-depth ventilation of the deep ocean by Antarctic slope waters exported at the South Scotia Ridge. |
