A review from the International Programme on the State of the Ocean (IPSO), warns that the oceans are facing multiple threats.
They are being heated by climate change, turned slowly less alkaline by absorbing CO2, and suffering from overfishing and pollution.
The report warns that dead zones formed by fertiliser run-off are a problem.
It says conditions are ripe for the sort of mass extinction event that has afflicted the oceans in the past.
It says: “We have been taking the ocean for granted. It has been shielding us from the worst effects of accelerating climate change by absorbing excess CO2 from the atmosphere.
IPSO, funded by charitable foundations, is publishing a set of five papers based on workshops in 2011 and 2012 in partnership with the International Union for Conservation of Nature (IUCN’s) World Commission on Protected Areas.
