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: In progress (Feb.-Apr.): NOAA A13.5 (Langseth) and NSF I08S (Thompson)
Up next: ARC01 (Healy, late Aug. through Oct.). As yet unconfirmed: NOAA A16S (late fall).
I09N is likely in early 2025 (Thompson). P04E may also occur in 2025.

Feb to March 2024 I08S (~90°E in Southern Ocean)
Departing from and returning to Fremantle, Australia, the R/V Thomas G. Thompson is undertaking the 4th full occupation of I08S (previously occupied in 1994, 2007, & 2016). I08S begins on the shelf south of the Antarctic Circle before heading north across the multiple fronts of the ACC. Find weekly reports & cruise blogs here.
Fall 2024 ARC01 (North Pole Crossing)
Departing from Tromsø, Norway, the USCGC Healy will make the first ever single ship, single season trans-Arctic crossing. These high-resolution surface to bottom multidisciplinary observations will be compared to earlier datasets (1987, 1994, 2005, 2015 ) to better understand Arctic change.
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.
