U.S. JGOFS Antarctic Environment and Southern Ocean Process Study (AESOPS)
The Antarctic Environment and Southern Ocean Process Study (AESOPS) survey and process cruises took place over a period of approximately one and a half years and were designed to encompass two Austral spring-summer periods of maximum biological productivity.
Process study cruises began in
Austral spring of 1996 (e.g., October), and terminated in late summer (e.g., March) of 1998. Work during the first
field season was concentrated on the Ross Sea continental shelf, and during the second year the focus shifted to the Antarctic Polar Front Zone (APFZ).
The split field season design of the program yielded observations in both regions covering two years during periods of
maximum anticipated biological productivity.
The Southern Ocean Process Study Implementation Plan explains the program in greater detail.
The AESOPS effort consisted of 11 cruises aboard the R/V Nathaniel B. Palmer and the R/V Roger A. Revelle working out of either Lyttelton, New Zealand or McMurdo Station, Antarctica.
Merged hydrographic data products have been compiled from the eight process and survey cruises summarized in the table below.
