The Northwest Pacific Basin is a region of the Pacific Ocean. To its west is the Kuril-Kamchatka Trench, which links Russia, Korea, and Japan; to its east is the Emperor Seamount Chain, an underwater mountain range that reaches Hawaii. Its southern border is near the Hawaiian islands of Necker Island and Marcus Island. It is one of the ocean regions where cyclones and typhoons form.
Its primary seas include:
- Sea of Okhotsk
- Kamchatka Shelf
- Bering Sea
- Northern Honshu
- Sea of Japan
- Yellow Sea
- East China Sea
Some of the chief islands of the Northwest Pacific are:
- Aleutian Islands
- Puget Sound
- Kuril Islands
- Japanese Islands
- Vancouver Island
The Northwest Pacific’s range includes tropical islands, but the water in its northern regions is cold. Fish that thrive in these cold waters include the Pacific halibut, salmon of all varieties, and gold country pollock. There are 13 whale species native to the Northwest Pacific.
Its marine life includes gray whales, humpback whales, blue whales, minke whales, and sperm whales. The waters are home to killer whales, bottlenose dolphins, and Pacific white-sided dolphins. Porpoises include the Ball’s porpoise and harbor porpoise.
Its waters are important fishing grounds for mackerels, tunas, shrimps, sardines, milkfish, sea breams, croakers, and seaweed.
One of the most important fish of the North Pacific is the herring. Like sardines and anchovies, herrings are forage fish. They are a vital food source for a huge number of larger fish and endangered marine mammals. Salmons, porpoises, seals, and other animals swarm the waters during herring spawning seasons.
Unfortunately, herring populations have dropped in recent years. Conservation groups along the Northern Pacific coastline are working to restore the population of these critical fish.
Millions of seabirds make their home on the coastlines of the Pacific Northwest. These include auklets, puffins, fulmars, terns, and almost all of the world’s 250,000 red-legged kittiwakes (Rissa brevirostris).
