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.
