Sea surface temperature the passing of a hurricane primarily as the result of mixed layer deepening and surface heat losses. In the wake of several day long Saharan dust outbreaks across the adjacent northern Atlantic Ocean, sea surface temperatures are reduced 0.2 C to 0.4 C (0.3 to 0.7 F). Other sources of short-term SST fluctuation include extratropical cyclones, rapid influxes of glacial fresh water and concentrated phytoplankton blooms due to seasonal cycles or agricultural run-off. The Atlantic Multidecadal Oscillation (AMO) is important for how external forcings are linked with North Atlantic SSTs. El Niño is defined by prolonged differences in Pacific Ocean
Pacific Marine Ecozone (CEC) coast, so there is little oceanic water exchanged between the Arctic and Pacific ecozones. The moderating effect of the Pacific Ocean results in a nearly constant year-round temperature in this ecozone. The Alaska Peninsula also inhibits the flow of cold Arctic currents from entering this zone, ensuring that throughout its extent, there is little variation in temperature. In fact, there is little exchange of oceanic waters between the Pacific Ocean and the Arctic Ocean. Ice forms here infrequently, and only in its northern areas in the Bering Sea and the Sea of Okhotsk. Pacific Marine Ecozone (CEC) The Pacific Marine
