  abstract = {{T}wenty years of daily {MODIS}-{A}qua ocean color observations (2002-2022) are used to identify periodic variability of near-surface chlorophyll ({C}hl a) in the {I}ndonesian seas. {T}he frequency spectrum of {C}hl a is dominated by the mean and low-frequency monsoonal variability; however, a prominent peak around the fortnightly tidal period, {MS}f, is present. {H}armonic analysis is used to quantify and map the fortnightly {C}hl a signal, which is discovered to be significant along the continental shelves of {NW} {A}ustralia and at several sites associated with narrow passages between the {L}esser {S}unda {I}slands, within the {S}ulu {A}rchipelago, and at a few other sites in the {P}hilippines {A}rchipelago. {F}ortnightly variability at the shallow coastal sites is attributed to the spring-neap cycle of barotropic ocean currents, while we hypothesize that the variability in deeper water near the island passages is due to the modulation of vertical nutrient fluxes by baroclinic tidal mixing. {T}he results document the significance of tidal mixing and highlight the heterogeneous character of biophysical processes within the {I}ndonesian seas.},
