Antarctic Intermediate Water formation in the Southeast Pacific
APEX Profiling Floats


Principal investigators: Lynne Talley and Teresa Chereskin, Scripps Institution of Oceanography, UCSD
Overview: AAIW profiling floats


Two websites contain the information for the AAIW APEX profiling floats:
  • Primary data acquisition site: University of Washington
  • Processed and plotted data: Scripps Institution of Oceanography (this site)

    We have deployed 3 APEX-SBE profilers with oxygen sensors to provide background profile context for the AAIW formation experiment. The floats are parked at 500 dbar and alternately profile from 500 dbar and 1800 dbar to the surface every 5 days.

    The first figure shows the current position of the floats.
