Cellular-level control on global ocean deoxygenation driven by phytoplankton ecophysiology Open
Phytoplankton elemental composition shapes the distribution of dissolved nutrient concentrations and thus plays a key role in ocean biogeochemistry. While the carbon-to-nitrogen-to-phosphorus ratio (C:N:P) in marine phytoplankton has been …

Predicting photosynthesis–irradiance relationships from satellite remote‐sensing observations Open
Photosynthesis–irradiance (PI) relationships are important for phytoplankton ecology and quantifying carbon fixation rates in the environment. However, the parameters of PI relationships are typically unknown across space and time. Here we…

A model of time-dependent macromolecular and elemental composition of phytoplankton Open
Phytoplankton Chl:C:N:P ratios are important from both an ecological and a biogeochemical perspective. We show that these elemental ratios can be represented by a phytoplankton physiological model of low complexity that includes major cell…
