The physics of our oceans, with Craig Stevens of NIWA

2015 was the hottest year on record. So what does that mean for our oceans, which capture 90 percent of that energy?

Craig Stevens, a physical Oceanographer from NIWA specialises in looking at just how the ocean works, and the role it plays in climate change.  He believes at present climate change is 90 percent an ocean story - as scientists grapple with just how much the oceans can handle the extra heat, and what that will mean for the planet.

Craig Stevens also specialises in ocean turbulence, stratification and waves - including the undersea tsuanmis which transfer energy around the world.
