Update on OneArgo and GO-SHIP: Sustained Ocean Observations for Heat, Freshwater, Biogeochemistry, and Tracers

Abstract

The Global Ocean Observing System (GOOS) is the international partnership of sustained ocean observing networks that provide data sets critical for a wide range of applications. We highlight the two GOOS networks providing deep interior ocean observations: Argo (Core, Deep, and Biogeochemical profiling floats) and GO-SHIP (ship-based measurements).

Argo is the dominant provider of data for tracking ocean heat content and the associated sea-level change, and is of growing importance for ocean carbon inventory, acidification and deoxygenation. Argo data are essential for ocean, climate and weather forecasting services. and are already transforming ocean biogeochemical and ecosystem state evaluation.

GO-SHIP data are the global reference source of traceable information about deep ocean warming, freshening, and biogeochemical change, on decadal time scales. GO-SHIP's highest-accuracy measurements complement and serve as a reference for other ship measurements and autonomous systems, including Argo.

This town hall will provide an update on the status of OneArgo and the upcoming decadal GO-SHIP survey, which will encompass the International Polar Year 5 (2032-2033).

We will seek feedback from the community regarding (1) status of current plans, (2) ease of access and interoperability of data, and (3) emerging issues that GO-SHIP and OneArgo are facing, including international funding pressures.
