Datasets for the Study 'Long-term Decline of Planktonic Biomass in a Hotspot of Nitrogen Fixation

This collection of datasets accompanies the study “Long-term Decline of Planktonic Biomass in a Hotspot of Nitrogen Fixation” and contains all the data necessary to reproduce the main analyses and figures presented in the paper.It includes in situ biogeochemical observations, satellite-derived optical properties, and algorithm-based estimations of particulate organic nitrogen (PON) in the western tropical South Pacific Ocean.本数据集合集配套于题为《热带南太平洋西部固氮作用（Nitrogen Fixation）热点海域浮游生物生物量长期下降》的研究，包含复现该论文中所有主要分析与图表所需的全部数据。本合集涵盖热带南太平洋西部的原位生物地球化学观测数据、卫星反演光学特性数据，以及基于算法估算的颗粒有机氮（particulate organic nitrogen, PON）数据。
