Valuable Pacific Dataset Expanded
NCEI has published an updated version of the Northeast Pacific (NEP) Regional Ocean Climatology. This product describes the long-term state of essential environmental ocean variables. The updated NEP climatology is a subset of the World Ocean Atlas based on the World Ocean Database archive of temperature and salinity observations, which span more than a hundred years. The new climatology incorporates a significant amount of new, previously unavailable data. What is a Climatology? A climatology, as defined by the World Meteorological Organization, refers to the long-term average of a given variable—typically temperature—over various time periods. In oceanography, "ocean climate" specifically describes ocean parameters averaged over a decade or longer. For instance, a monthly decadal ocean climatology provides a value for each month, averaged over a selected decade. Ocean climatologies focus on long-term averaged oceanic parameters such as temperature, salinity, and oxygen. There are global climatologies that cover the entire World Ocean, as well as regional ones for specific ocean regions. NCEI develops ocean climatologies for annual, seasonal, and monthly periods. This supports scientific analyses and investigations into interannual-to-decadal ocean climate variability using historical oceanographic data. The NEP climatology's initial version utilized data from the World Ocean Database 2018 (WOD18). Significant advancements
