California Current (IMAGE)
Caption
The researchers modeled the upper ocean off the West Coast, from Baja California to Canada's Vancouver Island. The top surface shows whether the upper ocean contains enough oxygen for a model marine animal: When the fraction is 1 (upper surface is blue), the animal could inhabit the entire upper ocean, from the surface to 200 meters depth. When the fraction is 0 (upper surface is red), the animal does not have enough energy for its normal activities in that part of the ocean. The water becomes uninhabitable when temperature (bottom left) is higher and oxygen concentration is lower (bottom right).
