In a sea of bad there’s some really good news: Krill and the cold currents that helps sustain this valuable food source is finally showing some improvement. Krill is integral to the ocean food chain as its the primary food source for many marine mammals and fish.
In a recent San Francisco Chronicle story, scientists studying the Northern Pacific Ocean currents are seeing an abundance of nutrient rich currents:
For the time being, many species of sea birds, fish and marine mammals are flourishing, and the reason lies largely in an unexpected change in two features of the ocean: The California current, flowing down the Pacific coast from Canada to Mexico, is colder than it has been in years, and strong northwest winds have increased the upwelling of cold water from just above the sea floor to the surface.
