Overview

GO-SHIP P16N is tentatively scheduled for mid-June to late July 2027, following NOAA OAR operations, with about 35 to 45 days at sea. This includes a 4-day allocation for reoccupying stations across the Gulf of Alaska, mirroring the 2015 occupation.

The cruise is slated to mobilize out of Kodiak, Alaska (or Seattle), and terminate in Honolulu, Hawaiʻi.

Ship and crew

R/V Ronald H. Brown (NOAA OAR), with about 28 science berths.

Operations

North-to-south occupation of the northern Pacific line, completing repeat hydrography across the Gulf of Alaska spur, core carbon and tracer measurements, Bio-GO-SHIP/eDNA sampling supported by NOAA PMEL/AOML, and associated float deployments.

Planning information

Data management and archival. All core hydrographic data are processed and submitted to the CCHDO (CLIVAR and Carbon Hydrographic Data Office) following standard GO-SHIP guidelines.

Logistics and compliance.

Strict biosecurity regulations apply (e.g., New Zealand biosecurity clearance, ISPM-15 compliant treated wood standards for shipping containers).
All participating personnel must complete required onboarding profiles (such as UNOLS Marine Facilities Planning) and review the US GO-SHIP Code of Conduct.
Mandatory pre-cruise training (such as joint Bystander Intervention Training) is coordinated ahead of field operations.
