“The Whale pump” by Roman J., McCarthy JJ (2010) :
A study in 2010 has attributed to whales a positive influence on the productivity of ocean fisheries, in what has been termed a “whale pump.”
Whales carry nutrients such as nitrogen from the depths back to the surface. This functions as an upward biological pump, reversing the assumption of some scientists that whales accelerate the loss of nutrients to the bottom.
They note that this nitrogen input in the Gulf of Maine is “more than the input of all rivers combined,” some 23,000 metric tons each year.
