Primary productivity estimates from the incubation of seawater collected at the Bermuda Atlantic Time-series Study (BATS) site from December 1988 through June 2024

Data presented are primary production estimates at the Bermuda Atlantic Time-series Study (BATS) site in the Sargasso Sea from December 1988 (BATS Cruise 10003) through June 2024 (BATS cruise 10416). The rate of carbon fixation by autotrophs in seawater was determined by tracing the uptake of radioactive 14C from the inorganic form to the particulate organic form. Incubations were performed in situ at depths ranging from the surface to 140 meters from dusk to dawn. Seawater samples were collected prior to sunrise, separated into three light bottles and one dark bottle, and a radioactive 14C tracer added. The bottles were then deployed on an incubation array at their collection depths, and allowed to drift on the array for the full light day. Samples were recovered after sunset and filtered for subsequent analysis on a liquid scintillation counter.本数据集呈现的是萨加索海（Sargasso Sea）百慕大大西洋时间序列研究（Bermuda Atlantic Time-series Study, BATS）站位的初级生产力估算数据，时间跨度为1988年12月（BATS航次10003）至2024年6月（BATS航次10416）。海水中自养生物的碳固定速率，可通过追踪放射性14C从无机形态向颗粒有机形态的摄取过程得以测定。培养实验以原位方式开展，实施时段为黄昏至黎明，水深覆盖表层至140米：于日出前采集海水样品，将其分装为3个光照瓶与1个黑暗瓶，并加入放射性14C示踪剂；随后将培养瓶部署至对应采样深度的培养阵列中，使其在阵列上随洋流漂移完整的白昼光照时长。样品于日落之后回收，经过滤后使用液体闪烁计数器开展后续分析。
