Statistical analysis of the spatial distribution of oil spills detected using Synthetic Aperture Radars (SAR) in 2004-2015 at the sea surface in the Southeastern Baltic Sea was conducted. Number, area, and shape of oil pollution division between Exclusive Economic Zones (EEZ) of Poland, Russia, and Lithuania were estimated for the first time. The most polluted area of the Southeastern Baltic Sea is Russian EEZ, where 55% of the total amount of detected oil spills, and 52% of the total area of oil pollution were located. The average area of an oil spill detected within Territorial Sea (TS) and EEZ was estimated. Tail-shaped spills associated with oil discharge from the moving vessels are prevailed, and their amount and area within TS and EEZ were estimated.

“…Most of the observed oil spills do not result from accidents but from intentional discharges. According to the HELCOM data for the whole Baltic Sea, data of other authors, and our own data for the southeastern Baltic Sea, oil spills are mainly located along the main shipping routes in the Baltic Sea (Figure 1) [3,[6][7][8][9][10][11][12][13][14][15][16][17]. The concentration of oil spills close to the shore in the Exclusive Economic Zone (EEZ) of Latvia is the result of aerial observations predominantly within its territorial waters [6] (Figure 1).…”

“…Analogs of this system do not exist for other seas of the Russian Federation. Since 2004, the data obtained within the framework of this satellite monitoring is the only source of continuous information on the sea surface oil pollution in the southeastern Baltic Sea [9][10][11][12][15][16][17].…”

The results of long-term satellite monitoring of oil pollution of the sea surface in the southeastern Baltic Sea (SEB) are discussed in this paper. From June 2004 to December 2020, in total, 2780 Synthetic Aperture Radar (SAR) images from different satellites were received and analyzed. There were 788 oil spills detected in the study area. The oil spills were concentrated along the main shipping routes in the SEB. The volume of the detected oil spills was estimated. The average size of the spill was about 2 km2 or 0.8 m3. Seasonal variability of oil pollution shows a decrease in the number of oil detections in the autumn–winter period, which is associated with the prevalence of unfavorable wind conditions that limit the use of SAR technology for oil spill detection and navigation for small ships. In situ measurements show that seasonal variation in the concentration of oil products in seawater is characterized by a maximum in April and a minimum in July. Since 2007, a decrease in oil detections has been observed for the entire Baltic Sea, including the study area. The interannual variability also shows a decrease in the concentration of oil products in the water column. In the southeastern Baltic Sea, the volume of oil products released yearly to the sea surface from ships does not exceed 0.1% of the average instantaneous presence of oil products in the water column.

“…From 2004 to present, in the framework of the complex environmental monitoring of oil field Kravtsovskoye (oil ice-resistant fixed platform (OIFP) D-6) LUKOIL-KMN, Ltd. and a number of Russian and international research projects the satellite monitoring of oil pollution at the sea surface of the Southeastern Baltic Sea is carried out (Kostianoy et al, , 2005(Kostianoy et al, , 2006 Bulycheva et. al., 2016).…”

The results of satellite monitoring of oil pollution in the Southeastern Baltic Sea in 2004-2015 are discussed in the paper. Interannual and seasonal variability of oil pollution is investigated. A steady decrease in total oil pollution was observed from 2004 to 2011. After a sharp increase of oil pollution in 2012, oil pollution level has established at 0.39 PI Index. Maximum of oil spills is observed in the spring and summer, which is probably due to favorable weather conditions for the detection of oil spills on radar images. According to the analysis of the shapes of the detected oil spills, it was concluded that the main polluters of the sea surface are vessels. No oil spills originated from the oil platform D-6 was detected in 2004-2015. Results of numerical experiments with the Seatrack Web oil spill model show that in the case of potential discharge of oil from the D-6 platform, oil will not reach the Curonian Spit beaches during 48 h after an accident.
