Map Shows Vast Regions of Ocean Are Warmer -- 2013

Many parts of the Atlantic and Pacific are up by 1 degree Celsius or more

Most people equate global warming with the atmosphere, but detailed mapping shows that many regions of the world’s oceans are heating up, too. Data compiled and plotted by Marinexplore show that sea-surface temperatures across the Atlantic, Pacific and Indian oceans are up by about 1 degree Celsius and as much as 2 degrees C in certain spots.

The warming is not uniform, and parts of the Southern Ocean around Antarctica have actually cooled. Temperature changes are more mixed in the Arctic Ocean, up as much as 2 degrees C in some spots and down by 2 degrees C in others.

Roberto De Almeida, an ocean data engineer at Marinexplore, also notes that the Atlantic and Pacific oceans are heating up as deep as 700 meters and beyond. For graphics on that trend, see “Deep Heat Threatens Marine Life” in Scientific American.

Warming Ocean Threatens Sea Life Warming down to 700 meters could also affect currents, weather

... the data suggest that warming could affect most marine life, altering food chains and migrations. It could change the distribution of life—from tiny phytoplankton to big whales—across the seven seas. “The more the atmosphere warms up, the more heat it transfers to the ocean,” says Roberto De Almeida, an ocean data engineer at Marinexplore. “That heat propagates downward.”
