Arctic cod... Scientists figure out beluga's Beaufort Sea menu cbc.ca The scientists realized that the Beaufort is actually a layer-cake of sea water with various temperatures and salinity. At about 200 metres down, water originating in the Pacific Ocean begins to give way to colder, saltier water coming from the Atlantic. "It's a mixing zone," said Reist. "Mixing areas tend to be very species-rich and they also tend to be very productive. It concentrates the food and productivity in the area." This zone was true to form. "It provides the larder for one of the key species in the area — the Arctic cod, a small fish but a very pivotal one," Reist said. Team members found the cod in "huge concentrations." They also found the answer to what the beluga have been eating. Although data about the size of the fish population is still being analyzed, Reist said calculations suggest it would take millions and millions of the 12-centimetre-long fish to support the area's beluga and seal numbers.
