Implementation Plan
The U.S. Southern Ocean JGOFS program, called Antarctic Environment and
Southern Ocean Process Study (AESOPS), began in August 1996 and continued
through March 1998. The U.S. JGOFS AESOPS program focused on two regions
in the Southern Ocean: an east/west section of the Ross-Sea continental
shelf along 76.5°S, and a second north/south section of the Southern
Ocean spanning the Antarctic Circumpolar Current (ACC) at ~170°W (identified
as the Polar Front). The science program, coordinated by Antarctic Support
Associates (ASA), comprised eleven cruises using the R.V.I.B Nathaniel
B. Palmer and R/V Roger Revelle as observational platforms and for deployment
and recovery of instrumented moorings and sediment-trap arrays. The Ross-Sea
region was occupied on six occasions and the Polar Front five times. Mapping
data were obtained from SeaSoar, ADCP, and bathymetric systems. Satellite
coverage was provided by the NASA SeaWiFS and the NOAA/NASA Pathfinder
programs.
A full description of the U.S. JGOFS AESOPS program and initial scientific
results, appear in a series
of Deep-Sea Research Part II volumes.
