Alaska Current, surface oceanic current, a branch of the West Wind Drift that forms a counterclockwise gyre in the Gulf of Alaska.

Is the Alaska current warm or cold?

The Alaska Current is a southwestern shallow warm-water current alongside the west coast of the North American continent beginning at about 48-50°N.

What is the Alaskan coastal current?

The Alaska Coastal Current is a narrow, intense coastal current hordering the southern coast of Alaska. It is characterized by relatively low salinities and its transport is significantly influenced by the regional freshwater discharge.

Where does the Alaskan current originate?

The strong variability of flow through the passes has time scales which vary from weeks to years. The source of most of the flow into the Bering Sea basin is the Alaskan Stream, the northern boundary of the cyclonic North Pacific subarctic gyre. It provides relatively fresh surface waters and warm subsurface water.

Is the Gulf Stream current warm or cold?

Originating at the tip of Florida, the Gulf Stream is a warm and swift Atlantic Ocean current that follows the eastern coastline of the US and Canada before crossing the Atlantic Ocean towards Europe. It ensures that the climate of Western Europe is much warmer than it would otherwise be.

What are seas facing Alaska?

Most of Alaska is surrounded by water. To the north and northwest, respectively, are two Alaska bodies of water, the Beaufort Sea and the Chukchi Sea, both of which merge into the Arctic Ocean. To the southeast is the Gulf of Alaska, which blends into the Pacific Ocean. The Bering Sea is to the southwest.

What are equatorial waters?

The water mass of the permanent or oceanic thermocline (100–600 m) in the tropical Pacific from 20°S to 15°N. North Pacific Equatorial Water (NPEW) is found north of the equator; it is formed by subsurface mixing between SPEW and central water. …

How cold is the water in the Gulf of Alaska?

Sea water temperature all along the Gulf of Alaska coast is not yet warm enough for swimming and does not exceed 20°C. The warmest water temperature Gulf of Alaska now is 10.2°C (in Prince Rupert), and the coldest sea surface temperature today is 8.2°C (in Kodiak).

For what is the Gulf Stream famous?

The Gulf Stream is a powerful warm ocean current affecting the climate of the eastern coast of North America and the western coast of Europe and it is an important source of tidal energy.

Why is Alaska current warm?

Because this portion of North America lies between 30 and 60 degrees N latitude, the warmth associated with the north-flowing Alaska Current is spread to the adjacent landmass by the Prevailing Westerlies wind belt.

Which longitude is the Alaska Current located?

Alaska, USA Lat Long Coordinates Info

Is Anchorage on the Gulf of Alaska?

Rising from the gulf’s shores in Alaska are the high Chugach, Kenai, Fairweather, and St. Elias mountains. Ports along the gulf include Anchorage, Seward, and North America’s northernmost ice-free harbour, Valdez, which is the trans-Alaskan pipeline terminal.

How does the Alaska current affect fishing?

If you have anomaly warm water that’s in the southern part of these currents, it will work its way northward and spin its way into the gulf. … But when the currents shift, as they are now, fish that aren’t normally seen in Alaska are swimming north.

Where do warm ocean currents generally come from?

Warm ocean currents originate near the equator and move towards the poles or higher latitudes while cold currents originate near the poles or higher latitudes and move towards the tropics or lower latitudes. The current’s direction and speed depend on the shoreline and the ocean floor.

Where do cold ocean currents generally come from?

The cold currents often form when the air on the subtropical high blows over a cold mass of water, then the cold air is dragged to the equator. Warm currents, on the other hand, are large masses of warm water moving further away from the equator, at higher temperatures.

How far off Florida is the Gulf Stream?

The Gulf Stream stretches 40 to 50 miles wide off the coast of southeast Florida as it chugs and snakes, ultimately toward Iceland, at a clip of 2 to 4 miles per hour. First charted in 1770, the Gulf Stream is of huge importance globally and locally. The current is a kind of global weather machine.

What would happen without the Gulf Stream?

It would disrupt monsoon seasons and rains in places like India, South America and West Africa, affecting crop production and creating food shortages for billions of people. The decline of the Amazonian rainforest and the Antarctic ice sheets would also be put into fast forward.

What happens if the Gulf Stream collapses?

If the Gulf Stream slows, it could spell disaster. The lack of that consistent and predictable current shifting around water could lead to dramatic sea level rises across the east coast of the U.S., extremely cold winters in Europe, and devastating disruptions during monsoon season in the tropics.

Where is the barren straight?

Located between Alaska and Russia, the Bering Strait is the only marine gateway between the icy Arctic and the Pacific Ocean.

Can you see Russia from Alaska?

But it’s much easier to get a view of Russia view by heading out into the Bering Strait to one of America’s weirdest destinations: Little Diomede Island. …

Why is bering sea so rough?

The Bering sea, near the chain of the Aleutian Islands, is one of the most intense patches of ocean on Earth. Strong winds, freezing temperatures, and icy water are normal conditions. The combination makes for some of the most ferocious waves on the planet, where the water can rise and fall 30 feet on a normal day.

Why there is counter equatorial current?

Theoretical Background. The NECC is a direct response to the meridional changes in the coriolis parameter and the wind stress curl near the Intertropical Convergence Zone (ITCZ). In part the NECC owes its existence to the fact that the ITCZ is not located at the equator, rather several degrees of latitude to the north.

What is known as the Equatorial Counter Current?

equatorial countercurrent, current phenomenon noted near the equator, an eastward flow of oceanic water in opposition to and flanked by the westward equatorial currents of the Atlantic, Pacific, and Indian oceans. … The Pacific Equatorial Countercurrent is very strong and is definable year-round.

Where does the Benguela current flow?

South Atlantic Ocean Flowing along the coast of South Africa, Namibia, and Angola, the Benguela Current is the eastern boundary of a large gyre in the South Atlantic Ocean. The current mixes water from the Atlantic and Indian Oceans as they meet off the capes of South Africa.

Can you swim in Alaska ocean?

The ocean in Alaska is never going to be warm, which is a good thing in retrospect. But when it comes to swimming, you’ll probably be much more comfortable with a wet suit on. If you are a true water baby, grab a snorkel and check out all the beautiful underwater sea creatures while you’re at it!

Does the ocean freeze in Anchorage Alaska?

During most of winter, the sea temperature at Anchorage hovers just below the freezing point of fresh water. But over the long northern days of summer, water in Anchorage’s sheltered inlet of Knik Arm warms rapidly.

Does the Gulf of Alaska freeze?

These warm, open oceans must release this heat before ice can form. The waters will need to drop to about 28.5 degrees Fahrenheit — the freezing point of salty ocean water — to do that.

Can you swim in the Gulf Stream?

Yes, it is completely safe to swim in the Gulf of Mexico. Very rarely do we experience red tide or any other issues.

What warm current keeps Australian?

The East Australian Current sweeps warm water down the east coast of Australia. Like the Gulf Stream, the East Australia Current is pushed to the western edge of the ocean by the rotation of the Earth.

Is the Gulf Stream weakening?

The Gulf Stream has weakened substantially in the past decades, as new data and studies show. Weather in the United States and Europe depends strongly on this ocean current, so it’s important we understand the ongoing changes and what they will mean for our weather in the future.
