Dead or alive, plankton support marine ecosystems

As tiny as they are, marine plankton play pivotal roles in biogeochemical cycles and sustaining aquatic ecosystems, producing around half of the oxygen on Earth and also acting as carbon sinks. When they die, their decomposing cells produce dissolved organic carbon that can be transformed and stored in the ocean for thousands of years, so understanding plankton mortality is essential for uncovering the mechanisms behind marine ecosystems.
