内容記述 |
Lake Abashiri is a brackish lake under the stability of upper oligohaline water and lower polyhaline water. The boundary of two layers has gradually decreased with time. At the same time, this has led to an increase in salinity and eutrophication in the upper layer and to an acceleration of deoxygenation of the lower layer, attributed to occurrence of algal bloom and upwelling of bluish water. In this paper spectral reflectance of water surface was formulated by using NOAA/AVHRR data received in Kitami Institute of Technology, horizontal global and scattered solar radiation. In order to correlate the spectral radiance of NOAA/AVHRR Ch.1 with the spectral radiance emitted from water surface, transmittance and path radiance were calculated approximately by using the horizontal global and the scattered solar radiation. Finally, the chlorophyll-a concentration in the center of Lake Abashiri was estimated by the regression line of the chlorophyll-a concentration on the difference of spectral reflectance between fluorescence and absorption zone of phytoplankton. |
