Baroclinic variations of the southward flow in the interior region of the North Pacific subtropical gyre are presented with five hydrographic sections from San Francisco to near Japan during 2004-2006. The volume transport averaged temperature of the interior flow, which varies vigorously by a maximum of 0. 8°C, is negatively correlated with the transport in the layer of density 24. 5-26. 5σ θ, associated with changes in the vertical current structure. Transport variation in this density layer is thus mainly responsible for the thermal impact of the interior flow on the heat transport of the subtropical gyre.
