Lidar fluorosensor seawater monitoring during the Antarctic oceanographic campaign

oceanographic campaign (RN Italica, Nov'97-Jan'98). Sea water quality parameters (phytoplankton and yellow matterconcentration, turbidity and biomass productivity) have been remotely and in situ monitored during the cruise in the Rosssea and along the Southern Ocean transects up-to New Zealand. Georeferenced data have been collected and released onthematic maps. Algal blooms and temporal variations of the monitored quantities have been reported. Seawaters detailedspectroscopic analyses were carried out to distinguish among natural seawater components (tyrosine and tryptophan protein-like substances) and to identify phytoplankton pigments (Chl-a, b, c, carotenoids, phycoerithrin, and phaeopigments).Keywords: phytoplankton, fluorescence, chlorophyll-a, DOM, lidar, Ross Sea
