Description

The U.S. GEOTRACES GP17-OCE expedition departed Papeete, Tahiti (French Polynesia) on December 1st, 2022 and arrived in Punta Arenas, Chile on January 25th, 2023. The cruise took place in the South Pacific and Southern Oceans aboard the R/V Roger Revelle with a team of 34 scientists led by Ben Twining (Chief Scientist), Jessica Fitzsimmons, and Greg Cutter (Co-Chief Scientists). GP17 was planned as a two-leg expedition, with its first leg (GP17-OCE) as a southward extension of the 2018 GP15 Alaska-Tahiti expedition and a second leg (GP17-ANT; December 2023-January 2024) into coastal and shelf waters of Antarctica's Amundsen Sea.

The GP17-OCE section encompassed three major transects:

(1) a southbound pseudo-meridional section (~152-135 degrees West) from 20 degrees South to 67 degrees South;

(2) an eastbound zonal transect from 135 degrees West to 100 degrees West;

(3) and a northbound section returning to Chile (100-75 degrees West).
