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 repeat A13.5 (Jan.-Feb.) along 0E in the Atlantic has been canceled.

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

2023: Up next: NOAAs repeat of A16N and the NSF repeat of I05. Reoccupation of P04E is presently on hold.

A13.5 Canceled

January 2022 - In spite of the best laid plans, the A13.5 expedition set to sail from Cape Verde was canceled. The student blog intended to highlight GO-BGC & SOCCOM float deployments instead introduces this island nation off the coast of Africa.

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 Now Underway

The 2022 reoccupation of the P02 transect along 30°N began in April. There are two legs: 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 with another 4 deployments planned for leg 2. This expedition includes the first bio-only casts for BIO GO-SHIP, which is also performing underway genetics & image sampling throughout the cruise. In addition, it is the first time that GO-SHIP will collect EK-80 observations in tandem with SADCP and LADCP data on every cast. Be sure to check out our student blog here.
