Macro-scale patterns in upwelling/ downwelling activity at North american west coast
"The seasonal and interannual variability of vertical transport (upwelling/downwelling) has been relatively well studied, mainly for the California Current System, including low-frequency changes and latitudinal heterogeneity. The aim of this work was to identify potentially predictable pattern...
