Sentences with phrase «euphotic zone»

The term "euphotic zone" refers to the upper layer of water in a body of water, such as the ocean or lake, where sunlight can penetrate and support photosynthesis. It is a zone where plants and organisms that rely on sunlight for energy can thrive. Full definition
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.
Phages and viruses Diel cycling and long - term persistence of viruses in the ocean's euphotic zone — Frank O. Aylward — PNAS
if we shut down photosynthesis in the ocean's euphotic zone, it's game over.
euphotic zone the upper layers of a body of water into which sufficient light penetrates to permit photosynthesis
