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 would also have a second leg (GP17-ANT) into coastal and shelf waters of Antarctica’s Amundsen Sea.
The two legs of this cruise 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).
