Zooplankton fecal pellets, marine snow, phytodetritus and the ocean's biological pump
JT Turner - Progress in Oceanography, 2015 - Elsevier
The “biological pump” is the process by which photosynthetically-produced organic matter in
the ocean descends from the surface layer to depth by a combination of sinking particles …
