WATER TEMPERATURE, salinity, and others collected from PUERTO DESEADO 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 with the spatial distribution shown in Figure 2. At each of these locations Conductivity/Temperature/Depth (CTD) and Lowered Acoustic Doppler Current Profiler (LADCP) profiles were taken, together with water samples collected through the full water column for physical/chemical analysis.

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 This report presents the main science activities carried out during a cruise onboard B.O. Puerto Deseado, departing from and returning to Ushuaia, Argentina [17 February – 12 March, 2009]. The cruise was the first on the Antarctic CRossroad Of Slope Streams (ACROSS) program, an international scientific collaboration between Texas A&M University (U.S.), Earth & Space Research (U.S.), Institut Mediterrani D’Estudis Avançats (Spain) and the Instituto Antartico Argentino (Argentina). U.S. activities on this cruise were funded by the National Science Foundation. The Direccion Nacional del Antartico provided funds for this cruise’s ship time and logistics, as part of their Campaña Antartica de Verano 2008/2009. ACROSS is a U.S. contribution to the Synoptic Antarctic Shelf-Slope Interactions program, International Polar Year. 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. This particular Antarctic cross-slope contribution to the deep ocean will be monitored with an array of three moorings using direct current and temperature-conductivity measurements from a 1-year deployment. 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. Observational programs for ACROSS on this cruise consist of mooring deployments; a regional survey of hydrographic measurements of temperature, salinity, dissolved oxygen, oxygen isotopes, and lowered acoustic current profiling; transects of expendable bathythermographs; and deployment of satellite-tracked surface drifters (Figure 2). Data collection and processing on this cruise were mostly done by personnel (Table 1) from the Department of Oceanography and the Geochemical and Environmental Research Group of Texas A&M University; the Institut Mediterrani D’Estudis Avançats; the Instituto Nacional de Investigacion y Desarrollo Pesquero and the Centro Nacional Patagonico. All cruise data will be presented in a separate technical report after final error inspection, quality control and adjustments are carried out at Texas A&M University. Digital forms of all hydrographic and CTD data will be contributed to the National Oceanographic Data Center. Collateral biological activities included water sampling for microbiology and chlorophyll, benthic nets, and visual census of marine birds and mammals. These activities are not documented here.
