Document Summary
Gulf stream & kuroshio current (both warm) most rapidly lose heat to the atmosphere, (warm current flowing north under colder atmosphere -> net heat loss); equatorial pacific & atlantic take up heat from atmosphere. Sea ice formation can remove salt from the ocean (salt trapped in ice) Temperature more useful for identifying arctic water masses (more obvious change) though the water is salinity stratified. Potential density is defining property of water column stability (cannot increase with depth if water column in unstably stratified) Colder water has larger pressure change when brought down to the same depth as warmer water alpha gets larger at higher pressure. Medditeranrea water not found in south atlantic. Nadw formed in na but spreads through most of atlantic. Highest sea surface onshore asf, (coriolis force points southward, pgf points. Thermal wind relation: ocean current velocity decreases with depth. Eddies are generated by instabilities of large-scale ocean flows.
