if we shut down photosynthesis in the ocean's euphotic zone, it's game over.

Once these leave the euphotic zone, sinking into the ocean depths, the carbon can be sequestered for a season or for centuries.

The scientists focused on the ocean's biological pump, which exports organic carbon from the euphotic zone — the well - lit, upper ocean — through sinking particulate matter, largely from zooplankton feces and aggregates of algae.

The export POC flux at the seafloor was then calculated using an equation from Lutz et al. (2007) based on the mean and seasonality (standard deviation / mean) of primary production, as well as the mean export depth below the euphotic zone over a 12 - year period.

The euphotic zone was calculated from the mean surface chlorophyll concentrations using the Case I model of Morel and Berthon (1989), while the export depth was calculated by subtracting the euphotic zone depth from the water depth.

This same «web of life» was thought to exist in the sea, whereby the carcasses or feces of organisms living in the euphotic, or lighted, region of the seas, descended to the bottom where they became a source of food for bottom dwellers.

euphotic zone the upper layers of a body of water into which sufficient light penetrates to permit photosynthesis
