Preliminary results from the ecosystem model application to the northwestern Pacific

Abstract

A coupled 3D physical-biological model based on the POLCOMS and the ERSEM models has been as an initial attempt applied to the region. The model domain covers the sea region between 117.5° to 164.7° E in longitude, and 22.4° to 62.7° N in latitude with 1/10° horizontal resolution on a regular spherical coordinate and 42 s-coordinate levels in the vertical. Preliminary results from the numerical simulation are presented. The monthly variability of physical (temperature, salinity) and biogeochemical (chlorophyll-a, nutrients) variables simulated on the past10 years from 1992 to 2001 are compared with SeaWiFS Chlorophyll-a over the period of 1998 to 2001, climatological nutrients(nitrate, phosphate and silicate) data from WOA09(World Ocean Atlas 2009) and observations at the Korea Strait (129.098 and 34.790N) from 2006 to 2011.in latitude with 1/10° horizontal resolution on a regular spherical coordinate and 42 s-coordinate levels in the vertical.
