WebOcean circulation derives its energy at the sea surface from two sources that define two circulation types: (1) wind-driven circulation forced by wind stress on the sea surface, inducing a momentum exchange, and (2) thermohaline circulation driven by the variations in water density imposed at the sea surface by exchange of ocean heat and water with the … WebMar 15, 2024 · Summary. Schematic diagram of the thermohaline circulation in the North Atlantic. In this module, students first review some background material on density-driven deep currents in the oceans, and then create a STELLA model of the thermohaline circulation in the North Atlantic Ocean. The model is based on a classic 1961 paper in …

WebJun 6, 2024 · The warm salty water travels up the U.S. east coast, then crosses into the North Atlantic region where it releases heat and warms Western Europe. Once the water releases its heat and reaches the North Atlantic, it becomes very cold and dense again, and sinks to the deep ocean. The cycle continues. WebThe Thermohaline Circulation (THC) also referred to as the “Great Ocean Conveyor” or the Meridional Overturning Circulation (MOC), can be defined as the density-impelled circulation of the oceans. Thermohaline is derived from the Greek: thermo- for heat and -haline for salt, which constitute the density of water. irvine baxter online

WebThe circulation of the ocean is usually divided into two parts, a wind-driven circulation that dominates in the upper few hundred meters, and a density-driven circulation that dominates below. The latter is called the ‘thermohaline’ circulation because of the role of heating, cooling, freshening, and salini- WebAntarctic Sea ice is a critically important component of our Climate system. It is at once habitat for penguins, a moderator of the largescale atmospheric circulation and an influence on the global thermohaline circulation. While similar in many respects to Arctic sea ice, there are distinct differences.

WebThe thermohaline ocean currents have a strong effect on the Earth System. This “conveyer belt” type circulation moves heat around the Earth through all of the ocean basis; the interconnected process of “overturning circulation” helps to regulate Earth’s climate. WebThe thermohaline circulation is mainly triggered by the formation of deep water masses in the North Atlantic and the Southern Ocean caused by differences in temperature and salinity of the water. The great quantities of dense water sinking at polar ocean basin edges must be offset by equal quantities of water rising elsewhere.

WebStudents record their expectations and observations of water properties using a physical demonstration. Next, they watch a video and read an article to label a simple model of thermohaline circulation. Finally, students predict how the movement of water in ocean currents via thermohaline circulation might contribute to or interact with global warming …

WebIt is the movement of these density layers that create the deep water circulation. Since seawater density depends mainly on temperature and salinity (section 6.3), this circulation is referred to as thermohaline circulation. The main processes that increase seawater density are cooling, evaporation, and ice formation.
