2023 GO-SHIP P14N

JAMSTEC re-occupation of P14N (approximately north of 12°N) in 2023 boreal autumn

Our planet and oceans are both variable and rapidly changing, and the Global Ocean Ship-based Hydrographic Investigations Program (GO-SHIP) seeks to document how the Earth is changing from one decade to the next. The program makes high quality measurements of seawater chemistry, heat, and freshwater content from the ocean surface to the seafloor along specified lines that cross entire ocean basins, and seeks to repeat these measurements each decade. GO-SHIP is an international effort with contributions from many nations.

GO-SHIP P14N will leave Dutch Harbor, Alaska in October 2023 and arrive in Shimizu, Japan in November 2023.
