摘要：

Interzonal diel migrant plankton and nekton obtain organic carbon by feeding at night above the main pycnoline of subtropical and tropical oceans, and respire part of it by day in the interior of the ocean below the pycnocline. Using data from seven oceanic stations, and conservative models to compute respiration at depth, we show that this flux of respiratory carbon ranged from 20 to 430 mg C m-2 d-1 or 13-58% of computed particulate sinking flux across the pycnocline. If this flux occurs consistently between 50°N and 50°S, it will add about 5-20% (depending on method of calculation) to current estimates of global sinking flux of organic carbon across the pycnocline. © 1990.
