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. NSF GO-SHIP I05 (July-Sept. 2023) East to West along 32°S in the Indian Ocean.
2024: (Feb.-Apr.): NOAA A13.5 (Langseth) and NSF I08S (Thompson)
Up next in 2024: ARC01 (Healy, late Aug. through Oct.) AND NOAA A16S (late Oct. to late Dec.).
Up next in 2025: I09N is likely in early 2025 (Thompson). P04E may also occur in 2025.

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.
Austral Summer A16S along ~30°W
Leaving from Brazil in fall 2024, the NOAA Ship Ronald H. Brown will extend the A16N completed early this year occupying stations from 6°N to 60°S in the South Atlantic. This will be the 3rd full occupation of this line.
Stay tuned for the blog and weekly reports!

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.

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.
The DOI for the GO-SHIP Easy Ocean dataset and a requested statement of acknowledgement can be found here.
