Unformatted text preview: Gyre – large water-circulation system controlled by a balance between pressure-gradient force & Coriolis Effect. Thermohaline Circulation – Vent of water driven by water of different densities (cold and salty = mostly dense)-Driven mostly by North Atlantic o Ice forms & salty brine is left behind Denser water o This dense water sinks and draws water down quickly o Heats towards equator, and drives back towards arctic… has a slower effect than near the arctic Current take homes Surface Currents- Created mostly by wind, Coriolis Effect, &Gravity- Mostly in circular patterns- Big & Fast- Transports nutrients and organisms Deepwater Currents- Created by differences in densities of water (thermohaline circ)- Moves slowly, so does not transport most organisms- Transports massive amounts of heat throughout world’s oceans...
