The biological pump is not so much the result of a single process, but rather the sum of a number of processes each of which can influence biological pumping. Overall, the pump transfers about 10.2 gigatonnes of carbon every year into the ocean's interior and a total of 1300 gigatonnes carbon over an average 127 years. [3]
The oceanic whale pump where whales cycle nutrients through the water column Once this carbon is fixed into soft or hard tissue, the organisms either stay in the euphotic zone to be recycled as part of the regenerative nutrient cycle or once they die, continue to the second phase of the biological pump and begin to sink to the ocean floor.
Whale pump "Whale pump" – the role played by whales in recycling ocean nutrients. ... One exception is French Polynesia, where, in many parts, cetaceans are met ...
The diagram illustrates the material fluxes, populations, and molecular pools that are impacted by five cryptic interactions: mixotrophy, ontogenetic and species differences, microbial crossâfeeding, auxotrophy and cellular carbon partitioning. These interactions may have synergistic effects as the regions of the food web that they impact ...
Unlike the other large filter feeders, it relies only on the water that is pushed through the gills by swimming; the megamouth shark and whale shark can suck or pump water through their gills. [6] Manta rays can time their arrival at the spawning of large shoals of fish and feed on the free-floating eggs and sperm. This stratagem is also ...
Diagram featuring the typical skeletal of a toothed whale (top) and a baleen whale (bottom) The cetacean skeleton is largely made up of cortical bone , which stabilizes the animal in the water. For this reason, the usual terrestrial compact bones, which are finely woven cancellous bone , are replaced with lighter and more elastic material.

The model shown in the diagram at the right attempts to capture some of the predominant features that influence the shape of the sinking flux profile (red line). [21] The sinking of organic particles produced in the upper sunlit layers of the ocean forms an important limb of the oceanic biological pump, which impacts the sequestration of carbon ...
