What is the global ocean conveyor belt?

Jun 25, 2018 · The ocean is not a still body of water. There is constant motion in the ocean in the form of a global ocean conveyor belt. This motion is caused by a combination of thermohaline currents (thermo = temperature; haline = salinity) in the deep ocean and wind-driven currents on the surface.

Shutdown of thermohaline circulation - Wikipedia

A shutdown or slowdown of the thermohaline circulation is a hypothesized effect of global warming on a major ocean circulation. Data from NASA in 2010 suggested that the Atlantic Meridional Overturning Circulation had not slowed down, but may have actually sped up slightly since 1993. A 2015 study suggested that the AMOC has weakened by 15-20% in 200 years.

Thermohaline Circulation - Global Ocean Conveyor System

Thermohaline Circulation - Global Ocean Conveyor System. At that time, glaciers of several kilometers in thickness, covered large areas of Europe and North America, reaching as far south as New York and the Ohio River Valley. The temperatures in Greenland were 10°C (18°F) lower than today and tropical temperatures were 4°C (7°C) lower.

How long does it take for the ocean conveyor to circulate?

According to NOAA It takes almost a 1000 years to complete a cycle. I am not sure how accurate, or where the citation came from their information so take it with a grain of salt. Lecture notes from one of Columbia University's 2007 "The Climate System" class suggests this process takes between 100-1000 years. This paper says Thermohaline Circulation overturns deep water every 600 years or so.

Sep 13, 2010 · They found that ocean circulation was far from the uniform, smooth motion a "conveyor belt" model might indicate, and that over the past 50 years ocean circulation had grown weaker near the Equator but stronger in the northern regions. As Lozier told Adam Mann of Nature: "The more we look, the more complicated the ocean is." Mann went on:

Thermohaline Circulation - Fact Sheet by Stefan Rahmstorf

What is the thermohaline circulation (THC)? As opposed to wind-driven currents and tides (which are due to the gravity of moon and sun), the thermohaline circulation (Fig. 1) is that part of the ocean circulation which is driven by density differences. Sea water density depends on temperature and salinity, hence the name thermo-haline.
