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.

2022: NOAA GO-SHIP A13.5 (Jan.-Feb.) along 0E in the Atlantic - canceled.

2022: NSF GO-SHIP P02 (Apr.-Jul. 2022) along 30N in the Pacific - complete.

2023: Up next: NOAA's repeat of A16N (spring) and the NSF repeat of I05 (summer). Reoccupation of P04E is presently on hold.

Spring 2023 A16N

With 10 partial occupations since 1988, the third complete occupation of the Atlantic 20W line known as A16N (first two 1993 and 2013 ) is set to sail this coming spring . Leg 1 will depart Brazil in early March heading for Spain. Leg 2 will follow, departing in mid-April to arrive in Iceland in May. Stay tuned for links to the student blog and weekly reports.

Global Compilation of Dissolved Organic Matter

Measurements of dissolved organic matter (DOM) in the open ocean have increased greatly since the late 1980's.

2022 U.S. GO-SHIP P02 Completed

The 2022 reoccupation of the P02 transect along 30°N took place between April and July. Leg 1 (Guam to Honolulu, April to June, black crosses) and Leg 2 (Honolulu to San Diego, June to July, blue crosses). Ten GO-BGC floats were released on leg 1 and another 4 deployments on leg 2. This expedition included the first bio-only casts for BIO GO-SHIP, which also performed regular underway sampling including genetics and imaging. Full-depth UVP imaging took place at each station. In addition, it is the first time that GO-SHIP collected EK-80 observations in tandem with SADCP and LADCP data on every cast. Be sure to check out our student blog here. Find the weekly reports for both legs under our News Section. The data as they become available are here.
