New research has shown that carbon in feces, respiration, and other excretions from fishes make up about 16% of the total carbon that sinks below the ocean’s upper layers.
Ecosystems provide a huge range of benefits and services to humans – one of these is the extraction of carbon dioxide from the atmosphere and its burial either in sediments or in the deep ocean.
Now a team of scientists lead by Dr Grace Saba at Rutgers University and including Dr Clive Trueman from Southampton have amalgamated their existing knowledge to estimate the contribution of fish to the global export of carbon.
