Abstract

Comparison studies between satellite estimates and in situ measurements of primary production demonstrate that satellite chlorophyll-a bio-optical algorithms need regional calibrations, especially in the Southern Ocean. In this research, the data of the ENEA lidar fluorosensor collected during the 16th Italian Antarctic Oceanographic Campaign have been used to calibrate the chlorophyll-a algorithm of the Sea-viewing Wide Field-of-view Sensor in three hydrographic regions of the Ross Sea: Terra Nova Bay, Cape Adare zone and center of the Ross Gyre. The results show that non-regional calibrated chlorophyll-a algorithms could misestimate primary production up to 50% - 75%. Finally, the corrected values of primary production have been calculated monthly and yearly in each of the abovementioned hydrographic regions. The values are in agreement with those found by other authors and provide information on the spatio-temporal distribution of primary production.
