CTD and Moored Current Meter and Hydrographic Measurements in the Southern Weddell Sea
Listed in NASA Earthdata CMR
This data set consists of data from ~120 CTD profiles collected over the southern Weddell Sea during the ROPEX-98 cruise on HMS Endurance, and data from current meters and (T,S) sensors on 4 moorings across the shelf break and upper slope, just west of the Filchner Depression.
Description
The hydrographic data are archived by the British Antarctic Survey (Cambridge, UK; contact Keith Nicholls), and data from moorings are archived by the Alfred-Wegener Institute (Bremerhaven, Germany; contact G. Rohardt).
The CTD data were obtained in February/March 1998 over the Ronne Depression and adjacent shelf regions in the southwestern Weddell Sea, an area that is usually inaccessible due to multi-year ice. Additional profiles were obtained in support of the current meter moorings. The 4 current meter moorings were deployed along a line across the shelf break west of the Filchner Depression, to monitor dense water outflow of Ice Shelf Water.

The sensors are in the lower water column, from ~9 m to ~400 m above the seabed. Current meters recorded hourly data from deployment in February 1998 to recovery by R.V. Polarstern in March 1999.
