Variable depth distribution of Trichodesmium clades in the North Pacific Ocean
Summary Populations of nitrogen‐fixing cyanobacteria in the genus Trichodesmium are critical to ocean ecosystems, yet predicting patterns of Trichodesmium distribution and their role in ocean biogeochemistry is an ongoing challenge. This may, in part, be due to differences in the physiological ecolo...
