RESUMO
The database provides information on coastal protection structures (containing geosynthetic materials) located on the coast of the South-East Baltic, in the Kaliningrad Oblast (Russia) and the Pomeranian Voivodeship (Poland). The fragments of geosynthetics may enter the environment due to partial destruction and operational losses and become a new type of coastal pollution. The database contains the following sections: the tabular data about coastal protecting structures [ProtectingStructures_tab.xlsx]; the point vector geodata about these structures [ProtectingStructures_pnt.kmz] and used geosynthetic materials; the satellite images and photos [ProtectingStructures_images.pdf] demonstrated the general and close-up location of the coastal protecting structures in the satellite image, as well as their seeming. Information was collected during the ERANET-RUS_Plus joint project EI-GEO, ID 212 (RFBR 18-55-76002 ERA_a, BMBF 01DJ18005).
RESUMO
A webcam was installed on the shore of the South-Eastern Baltic (Kaliningrad Oblast, Russia) to monitor the beach dynamics and beach-cast (BC) daily from November 1, 2019, to October 31, 2020. The beach was formed not the whole year (77%). The most frequent BC residence time was one day (1-21, 4.1 on average, and 1-19, 4.3 on average days to the west and east of the groin, respectively). The BC consisted primarily of algae. Fresh BC occupied smaller area, and its layer was thicker than that of long-discarded and trampled BC. The specific amount of material (per m2) in a fresh BC was 3.7 times higher in volume and 2.6 times higher in weight than in long-discarded and trampled BC. For fresh and old BC, the specific volumes were 63 and 17 l per m2, respectively, and the specific masses were 48 and 18 kg per m2, respectively.
