U.S. Global Ocean Ship-based Hydrographic Investigations Program
US GO-SHIP is part of the international GO-SHIP network of sustained hydrographic sections, supporting:
- Physical oceanography
- The carbon cycle
- Marine biogeochemistry and ecosystems
- Global ocean/climate observing system
The US program is sponsored by US CLIVAR and OCB.
Funded by the National Science Foundation and NOAA.
2023: NOAA GO-SHIP A16N (March-May) two legs South to North along ~25°W in the Atlantic.
2023: NSF GO-SHIP I05 (July-Sept. 20223) East to West along 32°S in the Indian Ocean.
2024: Up next: A13.5 (Langseth, Jan.-Mar.) & I08S (Thompson, Feb-Mar.). Also being considered, but as yet unconfirmed - ARC01 (Healy, summer) and A16S (late fall).
I09N is likely in early 2025 (Thompson), but plans for the P04 reoccupation remain on hold.

Austral Summer 2024 A13.5 along ~0°E in the Atlantic
Peviously occupied in 1983/84, 1995, & 2010, the 2024 Jan-March occupation will be 4th repeat. See ads for open positions under "News & Jobs" above. Stay tuned for links to weekly reports from sea and the cruise blog.
Summer 2023 I05 Occupation in Indian Ocean along 32°S
July 2023, the R/V Revelle has departed Fremantle heading toward South Africa along approximately 32°S in the next occupation of the I05 line
This will be the fifth occupation of this transect that was also sampled in 1987, 1995 (occupied in 3 legs), 2002 and 2009. It is also the first time the line will be occupied heading from east to west. Weekly reports from sea can be found here. The cruise blog is here.
GO-SHIP Easy Ocean
Katsumata et al. (2022) present GO-SHIP Easy Ocean, a climate quality gridded synthesis of the land-to-land surface-bottom hydrographic observations from International GO-SHIP repeat occupations. It is intended to be simple to navigate and to have a multitude of uses such as numerical model validation, process study comparison, and decadal-scale quantification of ocean change.
