Researchers in Alaska are studying a shift in shark populations due to climate change, with salmon sharks and Pacific sleeper sharks increasing in numbers. The declining number of sea lions, seals, and other pinnipeds suggests that top predators have shifted from orcas and pinnipeds to orcas, sharks, and decreasing numbers of the latter.
Research teams have discovered oxygen decreases of 10-15% in the upper thermocline, a layer 100-600 meters deep. Slower ocean circulation and increased plant productivity may be contributing factors, potentially linked to climate shifts and global warming.
