Ocean deserts are expanding much faster than expected, according to the National Oceanic and Atmospheric Administration. These deserts are felt to be created by warming ocean temperatures and may negatively affect the populations of many fish species trying to survive. Between 1998 and 2007, the area of saltwater with low surface plant life in the Pacific and Atlantic Oceans grew by 15 percent. This expansion of ocean deserts is correlated with an annual one percent rise in the sea surface temperature since 1998. The research showed that the areas of low productivity in the Pacific Ocean are expanding
from the center toward Hawaii. The least productive areas of the Atlantic Ocean are expanding at an even more rapid rate eastward across the Caribbean toward Africa.
