On the basis of three expeditions’ data obtained using optical observation methods, the total suspended matter (TSM) concentration field structure regularities are considered depending on water column stratification at the site of waste water discharge of the Herakleian Peninsula southern coast region. It was revealed, that TSM field is extremely inhomogeneous in the studying area; its distribution is largely determined by the background density stratification. On the sea surface, against the background with low natural TSM concentrations, the individual TSM content spots of ten times higher concentration than the surrounding background were observed. It is shown that anthropogenic suspension spreads to a distances of 0.5-1.5 miles from the release site. The known sewages’ distribution regularities from the deepsea outlets, determined by the water column stratification, are confirmed.
Based on data of several oceanographic surveys and coastal observations, the structure and temporal variability regularities in colored dissolved organic matter (fDOM) field concentration in the waters of the Abram Bay (Crimea) in the dry summer season of 2020 were revealed. It is shown that the rains and storm runoff are the most significant factors causing the anthropogenic fDOM accumulation in the bay. The main factor contributing the investigated substance of anthropogenic nature minimum content is upwelling, which was observed in July 2019 and 2020. It was revealed that, under the typical summer season conditions, the fDOM field was relatively stable.
On the base of complex expedition data, information about the water circulation, its nature and local features, its role in the thermohaline, total suspended and dissolved organic matter waters’ structure distribution formation, in alongshore flow and coastal Ekman upwelling formation was obtained. The sources of their supply were identified, the factors determining their following distribution and sedimentation were evaluated.
A new fluorescence meter for dissolved oil in water environment measurement is presented. An error components are considered. Results of measurements in the surface layer of Sevastopol Bay (Crimea) are performed.
The main features of contaminated wastewaters' transformation, that manifest themself in the fields of hydro-optical characteristics under conditions of intensive upwelling development, based on total suspended, dissolved organic matter fields and thermohaline structure in situ monitoring are revealed for the coastal part of the Heracles Peninsula in conditions of wind driving.
Total suspended and dissolved organic matters' distribution in the Kerch strait as well as the factors they are formed by are considered. It is revealed that water circulation is caused by the wind regime and surges influence, the meridional winds are the most significant ones that determine the Black Sea and the Sea of Azov water masses transportation. The pollution sources’ location for the Kerch strait waters determine the hydrooptical fields' formation and their transformation.
Results of complex Balaklava Bay waters' (the Black Sea) investigations received by using the multiparametric optical and biophysical complex "Kondor" are presented. Information on total suspended and dissolved organic matter fields' structure is received. A new method of dissolved oil products content determining is proposed, results of data comparing with the direct analytical method are presented, measuring error is estimated.
