... continuity, global coverage, and high temporal and spatial resolution of ocean color products make remote sensing a critical tool for monitoring and characterizing ocean biology 1 An algal bloom is defined as a rapid accumulation of algal biomass.

... For the first time, scientists have been able to obtain a global synoptic view of the biomass of phytoplankton in the ocean. This unique observing platform has also allowed scientists for the first time to visualize and study dynamic features, such as mesoscale eddies and ocean fronts, and their impact on ocean biology.

Only since the availability of ships or moorings, demonstrates the incomparable value of ocean color satellites have scientists been able to routinely remotely sensed ocean color data for tracking phytoplankton estimate global net primary production on weekly to interbiomass variability in different ocean regions over time. Sus annual time scales and thus to detect global trends (NRC, taining this record is essential to test many hypotheses about 2008a)

The discovery highlights how data with CZCS observations from 1979 to 1983, and SST little we know about the open ocean and how our understand- observations from both periods, suggest that the basin-scale ing of the complexity of marine ecosystems evolves. Ocean phytoplankton responses were related to the Pacific Decadal color data have played and will play a crucial role in the Oscillation and the Atlantic Multidecadal Oscillation with discovery process.

To sustain fisheries, management practices does environmental variability affect annual recruitment?
