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

2023: Look for the NOAA repeat of A16N and the NSF repeats of I05 and P04E.
