net ecosystem production (NEP)

Earth science; Physical oceanography

The rate at which carbon from the atmosphere (as CO2) is accumulated in the biosphere. It is equal to the NPP minus heterotrophic respiration.

emittance

Earth science; Physical oceanography

The rate at which radiation is emitted from a unit area.

temperature lapse rate

Earth science; Physical oceanography

The rate of decrease of temperature with height.

lapse rate

Earth science; Physical oceanography

The rate of decrease of temperature with height. This can be either an environmental or a process lapse rate. An environmental lapse rate is a static measure of the state of the ...

effective scattering cross-section

Earth science; Physical oceanography

The ratio of backward scattering intensity to density of irradiation flux.

chlorosity

Earth science; Physical oceanography

The number of grams of chloride and chloride equivalent to the bromide in one liter of sea water at 20° C.

nutrients

Earth science; Physical oceanography

The nutrients used as tracers in physical oceanography are essential dissolved chemicals eaten by plants in the ocean, i.e. phytoplankton. The basic nutrients are carbon, nitrogen ...
