Underway net community production from the US GEOTRACES GP17-OCE cruise on R/V Roger Revelle (RR2214) in the Pacific and Southern Oceans from November 2022 to January 2023

These data include underway temperature, salinity, dissolved oxygen (O2), satellite-derived chlorophyll a and net primary production, and budget-derived net community production (NCP) collected during the US GEOTRACES GP17-OCE cruise from San Diego to Punta Arenas in the Pacific and Southern Oceans. By integrating underway O2 measurements with global O2 data products and satellite data, all components of the surface oxygen budget were constrained, with NCP estimated as the residual term. Our results not only significantly advance understanding of the ocean's biological pump (BP) across diverse biogeochemical regimes but also help validate export estimates from satellite-based productivity algorithms. Since underway O2 data are commonly collected on most research ships, such as during the Global Ship-Based Hydrographic Investigations Program (GO-SHIP), our method for estimating NCP can be applied on a global scale, which contributes to a more comprehensive understanding of the regional variations of the strength of the BP, especially at sub-seasonal time scales.
