Seismic stratigraphy, architecture and outcrop pattern of the Wenlock-Přidoli sequence offshore Saaremaa, Baltic Sea

►250-500 Hz seismic profiling allows to map Silurian regional stages offshore Saaremaa. ►Architecture of Silurian seismic units reveals basinal slope of Baltic Silurian Basin. ►Deeper/thicker facies varieties are exposed at seafloor from Saaremaa towards Gotland. ►Pattern of exposed units reveals Cenozoic cuesta and Pleistocene glacial erosion. ►These erosions have had essential role in formation of Baltic Sea depression.
