Sentences with phrase «warm surface waters northward»

In the Atlantic Ocean, the current known as the Atlantic Meridional Overturning Circulation (AMOC) ferries warm surface waters northward — where the heat is released into the atmosphere — and carries cold water south in the deeper ocean layers, according to the National Oceanic and Atmospheric Administration.

Not exact matches

In today's ocean, warm, salty surface water from the Caribbean, the Gulf of Mexico, and the equatorial Atlantic flows northward in the Gulf Stream.

It is a narrow (85 km) and very shallow (55 m) strait with a continuous northward flow (1 m / s) that siphons warm surface water from the Pacific.

The Atlantic Meridional Overturning Circulation (AMOC)- the transport of warm tropical surface water northward - is indeed propelled by dense water sinking in the North Atlantic and travelling equatorward in the deeper layers, but it also has a wind - driven component to it.

So warmer - than - normal surface waters in the South Atlantic created by the changes in atmospheric circulation during an El Niño should be transported northward into the North Atlantic (and vice versa for a La Niña).

You may be familiar with part of this circulation, the Gulf Stream, which brings warm, tropical surface water northward along the East Coast of the United States and funnels toward the poles.

ENSO (El Niño Southern Oscillation) variability is linked to the spinning up or down of the South Pacific gyre — as it brings more or less cold Southern Ocean water northward — along the Peruvian coast — to more or less displace warm surface water and initiate upwelling.

For example, reductions in seasonal sea ice cover and higher surface temperatures may open up new habitat in polar regions for some important fish species, such as cod, herring, and pollock.128 However, continued presence of cold bottom - water temperatures on the Alaskan continental shelf could limit northward migration into the northern Bering Sea and Chukchi Sea off northwestern Alaska.129, 130 In addition, warming may cause reductions in the abundance of some species, such as pollock, in their current ranges in the Bering Sea131and reduce the health of juvenile sockeye salmon, potentially resulting in decreased overwinter survival.132 If ocean warming continues, it is unlikely that current fishing pressure on pollock can be sustained.133 Higher temperatures are also likely to increase the frequency of early Chinook salmon migrations, making management of the fishery by multiple user groups more challenging.134

The Atlantic Meridional Overturning Circulation (AMOC)-- characterized by warm surface waters flowing northward and cold deep waters flowing southward throughout the Atlantic basin — is defined as the zonal integral of the northward mass flux at a particular latitude.

Cold water in the gyre then extends east and keeps warm salty surface currents from spreading northward towards Greenland.

More warm and salty subtropical surface water then can move northward into the eastern part of the North Atlantic basin.

In today's ocean, warm, salty surface water from the Caribbean, the Gulf of Mexico, and the equatorial Atlantic flows northward in the Gulf Stream.
