These are regions of warm water at the centers of the world's oceans. Scientists often refer to them as the ocean's biological deserts. Polovina has seen these biological deserts in the oceans expand by 15%, or 6.6 million square kilometers, over the past 9 years. To see a similar and persistent expansion of the regions that have the least productivity was quite surprising. These regions in the ocean, places lacking in ocean life, happen naturally. They occur when nutrients from the bottom of the sea are not mixed up towards the surface. It's thought that warming ocean surface temperatures, or changes in wind patterns, could keep nutrients in nearby waters from mixing. If so, that could explain why these ocean deserts are expanding. It's consistent with what we know about global warming, that as the oceans warm, we would expect this phenomenon to happen.
