Lidar calibration of satellite sensed CDOM in the Southern Ocean

Chromophoric dissolved organic matter (CDOM) is a key parameter in the biogeochemical cycles affecting the oceansÂ’ contribution to the carbon budget of the Earth system. Despite its importance, important ocean colour satellite radiometers do not provide CDOM as a standard product.

Within this framework, we are presenting a lidar-calibrated CDOM algorithm for satellite imagery. It is based on the data collected by the ENEA Lidar Fluorosensor onboard the research vessel Italica during the 18th Italian Antarctic Oceanographic Campaign carried out from 5 January to 5 March 2003 in the Ross Sea.

Although the results are preliminary, they provide valuable information on distribution and dynamics of CDOM in the Southern Ocean, one of the less studied but more interesting zones of our planet from a biological point of view because of a series of circumpolar fronts that result in the definition of different oceanographic provinces, where the development of endemic phytoplankton is favoured.
