Examination of 40 processed cloud-free NIMBUS CZCS images over New Caledonia and Loyalty Islands provides a first view of the remotely sensed near-surface chlorophyll distribution. The major pattern of the phytoplankton abundance is the same as the one detected from the SURTROPAC survey : in winter, enrichment in the south of New Caledonia; in summer, extensive #Trichodesmium$ blooms in the north east of New Caledonia. Much newer is the detection of mesoscale gyres trapped on the coast, narrow island mass effects, and generally detailed observations on the small and mesoscale variability around the islands.
