Astoria and ocean currents
Readers comments about Astoria s warmer waters caused by the warmer Columbia river are indeed correct. The west coasts cool waters are due to upwelling and the flow of colder North Pacific waters moving south. There is no Alaskan Current moving south however. It is the California Current which flows south. The Alaska current flows north. I pay attention to these sort of things as a former N Pacific and Alaskan commercial fisherman.
