Abstract

Surface chlorophyll-a concentration were measured in the Ross Sea and in the Antarctica-New Zealand transect by the lidar fluorosensor aboard the research vessel Italica during the 13th Italian Antarctic Oceanographic Campaign (December 1997-January 1998). The lidar measurements were compared to the data collected by the Sea-viewing Wide Field-of-view Sensor (Sea WiFS). The study area contained four distinct regions: coastal waters located east of Terra Nova Bay (chlorophyll-a 0.2-9 mg m-3), offshore waters of the Ross Sea (chlorophyll-a 0.03-7 mg m-3), offshore waters of the Ross Sea-New Zealand transect (chlorophyll-a 0.1-2 mg m-3) and coastal waters located south of New Zealand (chlorophyll-a 0.2-9 mg m-3). In coastal waters, lidar values were significantly higher than those of Sea WiFS. In offshore waters the discrepancy was lower and the experimental points were enough to calibrate the Sea WiFS chlorophyll-a algorithm against the lidar fluorosensor measurements in the Ross Sea.
