Comparative analysis of chlorophyll-a concentrations obtained using flow fluorometric measurements carried out on the
board vessel, and chlorophyll-a concentrations calculated by MODIS-Aqua and VIIRS satellite data of ocean color was
conducted. The ship data were adjusted to standard spectrophotometric measurements and vertical depth distribution of
phytoplankton. Investigations were done in the Bering and Chukchi Seas, De Long Strait in August 2013. In waters of
the Russian Eastern Arctic satellite radiometers versus ship-borne measurements of chlorophyll-a concentration were
overestimated, which was associated with relatively high content of colored dissolved organic matter at upper layers. In
De Long Straight satellite estimation didn't reflect overall viewing on the depth integrated chlorophyll-a concentration,
as in this area the bulk of the phytoplankton with chlorophyll-a concentration around 10-20 mg/m3 was located in the
depth layer with 3-5% illumination relative to the surface light level. In the analyzed waters VIIRS gave more accurate
measurements of chlorophyll-a concentration as compared to using MODIS-Aqua satellite data with processing
procedures № 2013.1.
The Information Telecommunication System "Solaris" was created to solve the actual problems of navigation. The
system allows analyzing an operational local and synoptic hydrometeorological situation on a vessel route to issue
recommendations to navigators about the optimization of the movement from the point of view for the safety of
navigation and economic efficiency. ITS "Solaris" represents a combination of two hardware-software complexes one of
which is fitted on the vessel, and the other one ashore. The ship complex is based on the use of regular ship radar station
to which AD converter and the computer with the software is connected. The coastal complex is a server that collects,
processes, analyzes stores and transmits satellite and ship information. To operate the system on a particular ship the
proposed model calculates the speed of the vessel, depending on the direction and speed of meteorological parameters
such as wind, waves and currents, of ice conditions. The system can be used in the initial planning of the route on the
basis of operational and climatic data according to the seasonal variability of the weather conditions. The created system
improves the safety of navigation and increase economic efficiency.
The estimation of the two most intensive climatic factors impacting on phytoplankton communities was carried out for
marginal seas of western Pacific. Influences of some tropical cyclones on chlorophyll "A" concentrations (obtained by
SeaWiFS) in 2001 were considered. It is shown that tropical cyclones cause local algae blooming at some regions. Also
influence of dust storms from Gobi desert on phytoplankton at the area of the Sea of Japan was analyzed for the spring of
2006. Vladivostok lidar station data and MODIS data were applied for the analysis. Ground lidar data have shown that
the most aerosol mass was in lower atmosphere layer (0-3 km). So dust storm could influence on the element
composition of surface seawater layer. The high correlation coefficient between time series of chlorophyll A
concentration and of aerosol optical thickness (at the 869 nm) was detected.
The investigation of the bio-optical features distribution in the upper ocean layer is one of the objectives of the satellite remote sensing. But, very often it is necessary to compare satellite data with simultaneous shipborne measurements to interpret some processes more definitely. The statistical processing of the chlorophyll (alpha) concentrations simultaneously measured by SeaWiFS and by the shipborne fluorometer installed on the training sailboad 'Nadezhda' in the sea of Tasmania is presented in this paper. It is shown that in both cases we have detected characteristic scales in the chlorophyll (alpha) space distribution caused by the internal Rossby scales.
