During March/April 1976 the small-scale structure of the Antarctic Polar Front was observed in the Drake Passage. The
observations were part of the International Southern Ocean Studies (ISOS) program called FDRAke 76. The purpose of the
program was to obtain densely sampled measurements of temperature,
salinity, dissolved oxygen, and chemical nutrients in
the Polar Front Zone (PFZ) and pilot measurements of horizontal
and vertical velocities in order to explain the above scalar
variability. The PFZ is a region where Antarctic and sub-Antarctic waters intermingle and presumably mix to affect the
properties of Antarctic Intermediate Water. A report on the
third leg of Cruise 107 of the R. V. THOMPSON is presented as
well as a description of the measurements and a preliminary
report of the data. A feature of interest is the pinching off
of a northward meander of the circumpolar current system into
a cyclonic ring of Antarctic Waters.
