Satellite-derived Ocean color (water-leaving reflectances; Rrs) has a vital link with marine ecosystems and the carbon cycle, as each optically active water constituent (e.g., phytoplankton) absorbs and scatters solar radiation in its inherent wavelength ranges. In a warming climate, multi-decadal ocean color data records are the fundamental measurement in deriving bio-optical variables and diagnosing marine ecological impacts on a global scale. However, the typical trend analyses cannot distinguish natural inter-annual variability and anthropogenic warming effects, and the climate impacts on the marine ecosystem were currently concluded from future climate simulations. In this study, we apply Ocean Physical Modes Projections to Ocean Color (OPM-OC) data to assess the climate change impacts on ocean color and ecology. Here, we show the evidence of ocean color shift by global warming to be bluer in the Tropics and greener in the high latitudes. We show where and when various climate forcings (such as global warming, ENSO, AMO, and PDO) separately modulate the ocean color spectrum on a global scale.
