Overview
U.S. GEOTRACES is planning to extend its meridional transect, initiated on the 2018 GP15 Alaska-Tahiti expedition, south to the Antarctic ice edge and then east to Chile (GP17-OCE). Because of the potentially important TEI inputs and transformations occurring in Antarctic waters and shelves, GP17 will also have a second leg (GP17-ANT) into coastal and shelf waters of Antarctica’s Amundsen Sea.
The two legs of this section will:
- Complete the meridional transect of the Pacific Ocean begun on GP15 (2018)
- Capture deep Pacific Ocean inputs to the Drake Passage
- Further our understanding of shelf and slope processes in the Amundsen Sea
- Study the behavior and distribution of TEIs in the Amundsen Sea Polynya(s).
- Characterize TEI biogeochemistry in the Antarctic Circumpolar Current
Cruise Planning Workshops
Dates: 6-8 May, 2020
Information: This online planning meeting brought together researchers who expected to submit proposals for one or both of the GP17 expeditions. Link to the workshop announcement.

U.S. GEOTRACES GP17-OCE Pre-Cruise Planning Meeting
Dates: 17-18 March, 2022
Location: Old Dominion University, Norfolk, Virginia. Venue website and map.
Objective: Coordinate the scientific objectives and supporting logistics for the research cruise from Tahiti to Chile (GP17-OCE) planned for December 2022-January 2023. The GP17-OCE transect will include a nearly meridional section from 20°S to 67°S, a zonal section along 67°S from 135° to 100°W, and a margin section from 67°S 100°W to the Chilean margin. Cruise leaders: Ben Twining, Jessica Fitzsimmons and Greg Cutter.
