Abstract We present a global compilation of in situ marine particulate organic carbon, nitrogen, and phosphorus concentrations (POC, PON, and POP, respectively), from multiple sources to provide one of the most comprehensive collections of marine particulate organic matter (POM) to date. The dataset includes 155137 measurements (70586 POC, 69290 PON, and 15261 POP) from 25944 independent stations, more than doubling the number of previously available observations.
Abstract Mathematical models of photosynthesis–irradiance relationships in phytoplankton are used to compute integrated water-column photosynthetic rates and predict primary production. Models typically ignore an important phenomenon observed in most experiments: photosynthetic rate remains constant over a range of irradiances before declining due to photoinhibition. Here we develop an approach that captures both photoinhibition and this plateau.
