The pacific decadal oscillation (pdo) refers to the seesaw oscillation in sea-surface temperatures across the north pacific ocean.
The top few millimeters of the ocean's surface are considered to be its sea surface temperature (SST). All physical, chemical, and most biological processes taking place in the ocean are influenced by this temperature either directly or indirectly. Global SST monitoring is carried out by sensors aboard satellites, buoys, ships, ocean reference stations, autonomous underwater vehicles (AUVs), and other devices.
In addition to giving us important information about the global climate system, SST monitoring explains how the ocean and atmosphere interact. This knowledge helps us predict the weather by allowing us to spot the beginning of the multiyear shifts in atmospheric pressure and wind speed known as the El Nio and La Nia cycles. Global weather patterns, ocean circulation, and marine ecosystems are all impacted by these changes. Anomalies in the SST have been connected to changing marine resources. We notice fish and other animals moving poleward as a result of rising temperatures. Coral bleaching, fisheries and aquaculture mortality, as well as ocean heatwaves and cold snaps, have all been connected to temperature extremes. At the Large Marine Ecosystem scale, we show the SST average for the entire country.
