The mysterious disappearance of the sardines has marine experts investigating why they aren't populating the British Columbia coast
The Kuroshio current is a relatively warm and therefore shallow Current that sweeps past the Japanese coast then
The bulk of the Kuroshio turns east to receive the southward-flowing Oya Current. This flow, known as the Kuroshio Extension, eventually becomes the North Pacific Current(also known as the North Pacific West Wind Drift).
The north pacific current then sweeps past the Canadian coast around British Columbia and the Sardine fishery
At this point, some of this water then finds its way down the North American west coast likely effecting Calfornia etc and becomes the California current in the figure below
The water then gets pushed back along the tropic of cancer to flow through South East Asia and along the Northern Coast line of Australia
This link will fill in the blanks if you're interested in how it all works but it doesn't look good for Americas West coast, or Australias North. I should add it takes many years for these Gyres to do a full circuation, i'd be surprised if someone didn't see this coming.
Just Sayin :) BM
