Comparative Data Analysis of Passive and Active Sounding of Biooptical Parameters of Sea Water Top Layer in Sea of Okhotsk and Sea of Japan in 2010
Abstract:An ASD upwelling sea radiation spectrometer and a FL3 lotic fluorometer were used for taking measurements during the expedition in 2010. The first apparatus obtains hyperspectral measurements of sea upwelling radiation, which make possible to calculate chlorophyll-A concentration and fluorescence, as well as concentration of dissolved organic matter. The second apparatus measures sea water fluorescence spectrums, which also allows estimating concentration of chlorophyll-A and dissolved organic matter. Comparison of such data will permit to directly develop regional biooptical algorithms without taking atmospheric correction into account. This in turn will allow for optimization of atmospheric correction processes used for ocean color satellite data.
Figure 1 shows the geographic location of analyzed data. White dots show measurements of the upwelling radiation radiometer, grey lines – lotic contact measurements of chlorophyll-A fluorescence. This chapter explores comparative data analysis of passive and active sounding of biooptical parameters of sea water top layer in sea of okhotsk and sea of japan in 2010.
