Acoustic midwater data from the Southern Quark, Baltic Sea, 2017
Martin Jakobsson, Christian Stranne
Acoustic midwater data from the Southern Quark, between Sweden and Åland, collected with a Simrad EK80 sonar in August 2017. Midwater echo sounders permit remote observations of changes in the water column, e.g. thermohaline stratification, turbulence, and suspended particles, as well as individual fish, fish schools, and zooplankton.

Data description
Midwater data from a Simrad EK80 wide-band split-beam sonar with center frequancies at 70 kHz and 200 kHz. The data are logged in Kongsberg's raw format (.raw), which is described by Kongsberg.
Comments
Data was collected from the ship R/V Electra in the region of the Southern Quark between Sweden and Åland (from Aug 6 to 17, 2017). The data corresponds to the two transects shown in Figure 8 in Jakobsson et al. (2019).
Project
The data was logged within a project supported by the Swedish Radiation Safety Authority aiming to investigate mass wasting and tectonic movements in the Southern Quark.
