Antarctic - Warming seawater will push Antarctic krill farther south

Rising ocean temperatures will alter the distribution and life cycles of Antarctic krill in the coming decades, according to a new study led by the University of Tasmania.

Antarctic krill are ecologically and commercially important animals.  They are the main food source for hundreds of marine species, including whales, seals, ice fish, and penguins.

The researchers investigated how changing ocean temperatures will affect the habitat and preferred food of krill, which is phytoplankton.

The study showed that 85 percent of the Southern Ocean will be impacted, and krill will likely move farther south where conditions are more favorable.
