Ocean current the windthe Coriolis effect plays a role in their behaviours. The thermohaline circulation is a part of the large-scale ocean circulation that is driven by global density gradients created by surface heat and freshwater fluxes. The adjective "thermohaline" derives from "thermo-" referring to temperature and "" referring to salt content, factors which together determine the density of sea water. Wind-driven surface currents (such as the Gulf Stream) travel polewards from the equatorial Atlantic Ocean, cooling en route, and eventually sinking at high latitudes (forming North Atlantic Deep Water). This dense water then flows into the ocean basins. While the bulk
Drift Creek Bridge Drift Creek Bridge The Drift Creek Bridge is a covered bridge in Lincoln County in the U.S. state of Oregon. Built in 1914, the structure originally carried Drift Creek County Road over Drift Creek. The creek flows into Siletz Bay of the Pacific Ocean south of Lincoln City. The original bridge, about from the ocean, once carried the main north–south route along the coast. Newer bridges later carried most of the north–south traffic and, after a concrete bridge bypassed the Drift Creek Bridge in the 1960s, Lincoln County preserved it as a pedestrian crossing and a monument to 19th-century pioneers.
