英文摘要	Exchange across the surf-zone and inner-shelf affects coastal water quality and larval recruitment. Surf-zone generated transient rip-currents (TRC) exchange shoreline released tracers onto and across a stratified inner-shelf. Surface heat fluxes (SHF) modify inner-shelf stratification and surf-zone temperature, relative to the inner-shelf, inducing nearshore thermally driven exchange. The coupled effect of TRC and diurnal SHF forcing on cross-shore exchange is evaluated using idealized model surf-zone tracer releases with TRC-only, SHF-only, and combined SHF+TRC forcing. For conditions representing Fall in Southern California, the TRC mechanism dominates cross-shore exchange, relative to SHF, to 12LSZ offshore (LSZ = 100 m is the surf-zone width). Tracer and velocity derived estimates of exchange velocity indicate that the TRC cross–inner-shelf exchange mechanism is due to an alongshore mean baroclinic flow setup by TRC vertical mixing of inner-shelf stratification. ©2020.
