  abstract = {{A} full two-way nesting approach for split-explicit, free surface ocean models is presented. {I}t is novel in three main respects: the treatment of grid refinement at the fast mode (barotropic) level; the use of scale selective update schemes; the conservation of both volume and tracer contents via refluxing. {A}n idealized application to vortex propagation on a beta plane shows agreement between nested and high resolution solutions. {A} realistic application to the {C}alifornia {C}urrent {S}ystem then confirm these results in a complex configuration. {T}he selected algorithm is now part of {ROMS}_{AGRIF}. {I}t is fully consistent with {ROMS} parallel capabilities on both shared and distributed memory architectures. {T}he nesting implementation authorizes several nesting levels and several grids at any particular level. {T}his operational capability, combined with the inner qualities of our two-way nesting algorithm and generally high-order accuracy of {ROMS} numerics, allow for realistic simulation of coastal and ocean dynamics at multiple, interacting scales.},
