Data sets

EMODnet Digital Bathymetry (DTM) EMODnet Bathymetry Consortium

Calculated seafloor ruggedness index (TRI) of the Baltic Sea M. Jakobsson

Acoustic midwater data from the Southern Quark, Baltic Sea, 2017 C. Stranne

Short summary
The bottom topography of the Baltic Sea is analysed using the digital depth model from the European Marine Observation and Data Network (EMODnet) published in 2018. Analyses include depth distribution vs. area and seafloor depth variation on a kilometre scale. The limits for the Baltic Sea and analysed sub-basins are from HELCOM. EMODnet is compared with the previously most widely used depth model and the area of deep water exchange between the Bothnian Sea and the Northern Baltic Proper.
