abstract
Results are presented from a hydrographic survey of the Prince Edward Island group (46�'S; 37�'E) during September 1982. These provide additional information about the hydrodynamics of this little-studied region. The distribution of conservative properties (temperature, salinity, density and oxygen) showed little vertical stratification, indicating that water around the islands is well mixed. It is postulated that topographical effects and the close proximity of the islands to the Antarctic Polar Front may combine to influence significantly biogeographic affiliations nearby. Such effects may also operate in concert with ephemeral run-off from the islands (particularly of nitrates) to affect marine productivity in the region.
