Abstract:
This data set includes measurements from moored instruments, collected at the southern Weddell Sea continental slope, in the period between 10 January 2009 and 10 January 2010. The data set was collected as a part of the International Polar Year project entitled “Bipolar Atlantic Thermohaline Circulation (BIAC)”, under the working theme “Downslope processes, pathways, cascading and mixing”. The objective was to study the dynamics and mixing of the dense overflow plume on the continental slope of the Weddell Sea northwest of Filchner Depression. Due to difficult ice conditions, the Filchner outflow site could not be accessed. Moorings were instead deployed on the southeastern Weddell Sea, on the central Crary Fan and further to the east. The positions were chosen to capture the variability associated with the slope current in the region, basin-shelf exchange as well as the tidal band variability.
The data set includes time series of ocean temperature, salinity and currents on the continental slope of the southeastern Weddell Sea at five locations in the region 74-75°S; 29-33°W. The observations from these moorings were reported in Jensen et al. [2013] who discuss the subinertial mesoscale variability attributed to trapped vorticity waves. Complete set of mooring drawings and detailed description can be found in the report (Fer, 2016) under 'Further details'.

Comment:
The measurements delivered with this data set are not gridded, and are submitted at the sampled time resolution. Time series are quality controlled and suspect data are removed (not interpolated). Mooring knock down was not significant, and only a simple correction is made using the measured pressure time series (i.e., mooring dynamics is not modelled). Complete set of mooring drawings and detailed description can be found in the report (Fer 2016, PDF provided). The temperature measurements were made by accurate temperature sensors on Sea-Bird Electronics SBE39 and SBE37 instruments, as well as by the temperature sensors on current meters and current profilers. Current measurements were made by Anderaa current meters (RCM7/8), Nortek current meter (Aquadopp), and various Doppler current profilers (ADCPs, RD-Instruments 75/300 kHz Workhorse and Nortek Continental). Instrumentation and other details of the moorings can be found in the report. The sampling rate was 5 min for the Microcat and SBE39, 1 hour for the RCM-7/8, RDI 75kHz and Continental, and 20 min for the Aquadopp and RDI 300 kHz.
