Warmer water temperature and decreased levels of oxygen in the ocean will act together to push marine animals away from the equator to places in the ocean where the oxygen supply can meet their future needs, says a study. The warmer water temperature will speed up the animals\' metabolic need for oxygen, as also happens during exercise, but the warmer water will hold less of the oxygen needed to fuel their bodies, similar to what happens at high altitudes, the researchers said.

Washington: Warmer water temperature and decreased levels of oxygen in the ocean will act together to push marine animals away from the equator to places in the ocean where the oxygen supply can meet their future needs, says a study. The warmer water temperature will speed up the animals' metabolic need for oxygen, as also happens during exercise, but the warmer water will hold less of the oxygen needed to fuel their bodies, similar to what happens at high altitudes, the researchers said.


About two thirds of the respiratory stress due to climate change is caused by warmer temperatures, while the rest is because warmer water holds less dissolved gases.The study centered on four Atlantic Ocean species: Atlantic cod that live in the open ocean, Atlantic rock crab that live in coastal waters, sharp snout sea bream that live in the subtropical Atlantic and Mediterranean, and common eelpout, a bottom-dwelling fish that lives in shallow waters in high northern latitudes. If current emissions continue, the near-surface ocean is projected to become warm by several degrees Celsius by the end of this century.
