Abstract. Harmonic analysis of time series from 20 years of MODIS-Aqua ocean color observations (2002–2022) is conducted to identify periodic variability of near-surface chlorophyll (Chl-a) inferred from ocean color. As they are based on satellite imagery, the Chl-a observations are characterized by significant gaps in both spatial and temporal coverage due to the masking of clouds in the images. Results yield a coherent picture of surface Chl-a associated with the time mean, annual and semiannual cycles, and spring-neap tidal variability. Spring-neap variability is heterogeneous and associated with regions of significant baroclinic tides as well as coastal regions with strong tidal currents. The observations provide another line of evidence for the significant contribution of ocean tides to mixing in the Indonesian Seas.

Short summary
Phytoplankton in the upper ocean are food for fishes and are thus economically important to humans; furthermore, phytoplankton consume nutrients and generate oxygen by photosynthesis, just like plants on land. Vertical mixing in the ocean is responsible for transporting nutrients into the sunlit zone of the surface ocean. We used remotely-sensed data to quantify the influence of tidal mixing on phytoplankton through an analysis of ocean color, which we interpret as chlorophyll concentration.
