Abstract

Now there are well known maps of vertical attenuation coefficient distribution over the World Ocean, which describe the upper 10 meters layer. For calculations the values of Kd from such maps are extrapolated usually to deep layers. But while the ocean is stratified optical characteristics may vary significantly in depth. So such approximation is not quite correct and calculation results, particularly for large depth, may have significant errors. For the last years with the use of a new device `Alfamer', a representative experimental array of data on vertical stratification of Kd was collected. The stratification data may improve an accuracy of E(Z) estimation. In this article Kd(Z) data are analyzed and generalized.
