We present the results of measurements of optical characteristics of waters (the beam attenuation coeffi-
cient, volume scattering function, sea water reflectance, and Secchi depth) and optical characteristics of
the atmosphere (aerosol optical thickness, content of vapors, and the Ångström exponent) carried out in
September 2008 on the oceanographic platform near Katsiveli. We carried out the comparative analysis
of hydrooptical characteristics measured in various years. The optical type of sea waters in the period of
observations is determined.
In September 2008, the staff of the Sea Optics Department of the Marine Hydrophysical Institute of the Na-
tional Academy of Sciences of Ukraine performed optical studies on the oceanographic platform located near the
South shore of the Crimean peninsula in the region of Katsiveli. The purposes of the studies were:
(i) determination of basic hydrooptical characteristics and the estimation of the biooptical state of sea wa-
ters by them;
(ii) study of regularities of the formation of radiation rising from the sea, which are used in algorithms for
the processing of measurements by satellite-borne optical scanners;
(iii) determination of optical characteristics of the atmosphere, which are needed for the optimization of a
regional algorithm for the atmospheric correction of remote sensing data.
Content of Measurements and Facilities
On the platform, we performed the measurements of the coefficients of beam attenuation, Secchi depth and
the color of water, volume scattering function (VSF), sea water reflectance, and optical characteristics of the
atmosphere in the period from September 9 till September 15.
We also carried out the corresponding hydrometeoobservations of cloudiness, wind, swell, and currents on
the sea surface.
Below, we present the data on the facilities used in the measurements on the oceanographic platform.
