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.本数据集包含美国GEOTRACES GP17-OCE科考航次在太平洋与南大洋海域从圣迭戈至蓬塔阿雷纳斯航段采集的走航观测温度、海水盐度、溶解氧（O₂）、卫星反演叶绿素a浓度、净初级生产力，以及收支模型推导的净群落生产力（NCP）。本研究通过整合走航溶解氧观测数据、全球溶解氧数据产品与卫星数据，约束了表层氧收支的全部组成组分，并以残差项形式估算得到净群落生产力。研究结果不仅显著提升了对不同生物地球化学区域海洋生物泵（BP）的科学认知，还可为基于卫星反演的生产力算法所得到的碳输出通量估算值提供验证支撑。鉴于多数科考航次（如全球船舶水文调查计划（GO-SHIP））均会采集走航溶解氧数据，本研究所提出的净群落生产力估算方法可推广至全球尺度，这有助于更全面地解析海洋生物泵强度的区域差异，尤其是在亚季节时间尺度上的变化特征。
