which of the following is true of north atlantic deep water course heri

What determines the water mass at depth in the ocean?

Jul 02, 2020 · North Atlantic Deep Water is MORE dense than surface water. Surface water absorbs most of the radiation from the sun, consequently it warms up, making the particle to have more space between each other. It causes the surface water to become less dense than NADW, so it is located on top of NADW.

Which latitudes have a heating deficit over the course of year?

of Antarctic Bottom Water and North Atlantic Deep Water. Associated with the Circumpolar Current is the Antarctic Convergence encircling Antarctica, where cold northward-flowing Antarctic waters meet the relatively warmer waters of the subantarctic, Antarctic waters predominantly sink beneath subantarctic waters, while associated zones of ...

What direction do Southern Hemisphere winds move the surface water?

Aug 06, 2020 · 2 .Would you expect the North Atlantic Deep Water to be more or less dense than the surface water? Why? More dense. It is because, NADW is located at the bottom of surface water, the liquid on the bottom indicates that it is most dense while the liquid on the top is least dense. 3.Which do you think has a greater effect on ocean water density ...

What does the North Atlantic Deep Water contain?

Globally, the North Atlantic deep waters are warm, saline, oxygen-rich, and nutrient ones whereas the South Atlantic ones are cooler, lower in salinity and oxygen and higher in nutrients.

What does North Atlantic deep water do?

NADW and its formation is essential to the Atlantic Meridional Overturning Circulation (AMOC), which is responsible for transporting large amounts of water, heat, salt, carbon, nutrients and other substances from the Tropical Atlantic to the Mid and High Latitude Atlantic.

Which of the Atlantic ocean water masses would you expect to find at the very bottom of the ocean?

The Antarctic Bottom Water (AABW) is the only natural water mass in the bottom layer, and this water mass is redefined as Northeast Atlantic Bottom Water (NEABW) in the north of the Equator due to the change of key properties, especially silicate.Mar 15, 2021

What is Atlantic deep water formation?

The Gulf Stream carries salt into the high latitude North Atlantic where the water cools. The cooling and the added salt cause the waters to sink in the Norwegian Sea. This is the formation of Atlantic Deep Water. Places where the water is cold enough and salty enough to form bottom water.

Which of the following is true of surface water circulation near Antarctica quizlet?

Which of the following is true of surface water circulation near Antarctica? The circulation of water around the Antarctic continent is driven by density differences. The surface ocean has no strong currents.

Where does North Atlantic Deep Water develop?

Formation and sources. The NADW is a complex of several water masses formed by deep convection and also by overflow of dense water across the Greenland-Iceland-Scotland Ridge.Nov 30, 2021

How deep is the North Atlantic Ocean?

The North Atlantic covers 41,490,000 km2 (16,020,000 sq mi) (11.5%) and the South Atlantic 40,270,000 km2 (15,550,000 sq mi) (11.1%). The average depth is 3,646 m (11,962 ft) and the maximum depth, the Milwaukee Deep in the Puerto Rico Trench, is 8,376 m (27,480 ft).

What are deep water masses?

Deep-water masses are produced at the surface of the ocean and transported to depth via downwelling. Generally, downwelling occurs where the surface ocean is cool, or, rarely, unusually saline.

What is the deepest point of the Atlantic Ocean?

27,841′Atlantic Ocean / Max depth

What is the name of the deep water current that begins in the North Atlantic Ocean adjacent to Greenland?

This very large, slow current is called the thermohaline circulation because it is caused by temperature and salinity (haline) variations. This animation shows one of the major regions where this pumping occurs, the North Atlantic Ocean around Greenland, Iceland, and the North Sea.

Which of the following is true of surface water circulation near Antarctica?

Which of the following is true of surface water circulation near Antarctica? Two circumpolar currents dominate it, one current that moves water to the east and one current that moves water to the west.

Why does water in the North Atlantic sink into the deep ocean quizlet?

In the Earth's polar regions ocean water gets very cold, forming sea ice. As a consequence the surrounding seawater gets saltier, because when sea ice forms, the salt is left behind. As the seawater gets saltier, its density increases, and it starts to sink.Jan 4, 2022
