More than 56% of the world’s oceans have changed color to an extent that cannot be explained by natural variability, said a team of researchers, led by scientists from the National Oceanography Center in the UK and the Massachusetts Institute of Technology in the US, in a statement. Tropical oceans close to the equator in particular have become greener in the past two decades, reflecting changes in their ecosystems, according to the study published Wednesday in the journal Nature.
It will also affect the ocean’s ability to act as a store of carbon, Dutkiewicz said, as different plankton absorb different amounts of carbon. While the researchers are still working to unpick exactly what the changes mean, what is clear, they said, is that the changes are being driven by human-induced climate change. ‘Clear trend’ The researchers monitored changes in ocean color from space by tracking how much green or blue light is reflected from the surface of the sea.
