The Gulf of Alaska (Tlingit: Yéil T'ooch’) [1] is an arm of the Pacific Ocean defined by the curve of the southern coast of Alaska, stretching from the Alaska Peninsula and Kodiak Island in the west to the Alexander Archipelago in the east, where Glacier Bay and the Inside Passage are found.
Winds and precipitation can both affect the Alaska Current. Winds are downwelling along the coastal area most of the year, which helps to keep the density contrast between central Gulf of Alaska water and fresher, lower density water on the shelf. The coastal current in the Gulf of Alaska is strongly baroclinic. Precipitation and coastal runoff ...
The primary focus was to study fronts, eddies, winds, waves, and tides; each of these processes produce a change in sea surface height of several meters. [5] In 1986, researchers Gower and Tabata observed clockwise eddies in the Gulf of Alaska using GEOSAT - the first satellite observation of Haida eddies.
The Alaska Current is the eastern boundary current of the subpolar Alaska Gyre, [18] while the California Current is the eastern boundary current that completes the North Pacific Gyre circulation. Within the North Pacific Gyre is the Great Pacific Garbage Patch , an area of increased plastic waste concentration.
Knowledge of surface ocean currents is essential in reducing costs of shipping, since traveling with them reduces fuel costs. In the wind powered sailing-ship era, knowledge of wind patterns and ocean currents was even more essential. Using ocean currents to help their ships into harbor and using currents such as the gulf stream to get back ...
The color of the ocean has changed significantly over the last 20 years and human-caused climate change is likely responsible, according to a new study.. More than 56% of the world’s oceans have ...
The Coast Guard announced the search Sunday morning, and responders could face tough conditions because part of the region, located in the Gulf of Alaska, is under a winter storm warning.
This is associated with a decrease in the speed of current; eastward directed speeds at the surface are typically less than 0.05 m/s (5 cm/s) in the central Pacific. As the NPC approaches the west coast of North America, it divides into two broad currents: the northward flowing Alaska Current and the southward flowing California Current.
