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.
- GP17 Statements of Interest: Links to all the submitted statements of interest to aid in the management proposal preparation for each cruise.
