Review of dense shelf water observations around Antarctica (presence or absence)

Shapefile with a review of georeferenced water column observations of dense shelf water flows around Antarctica, including observation number (N), location, type of observation (T; A: active, P: passive, N: Nil), date of observation, method of acquisition and reference. Different publications that refer to the same station site are grouped under the same observation number while stations separated by less than 1º of arc are coded with the same number but different letter. B&C (following Baines and Condie, 1998). ADCP is Acoustic Doppler Current Profiler; LADCP is Lowered ADCP; CTD is Conductivity Temperature Depth; XCTD is expandable CTD; XBT is Expandable Bathy Thermograph; SACM is Smart Acoustic Current Meter (suspended through the ice); CTD-ES is CTD installed on elephant seals. Moorings include current meters, and temperature and salinity sensors. For details about the instrumentation see the original references.
