Additionally, video visualisations of the acoustic midwater data are provided. Co-located with the acoustic broadband observations are in situ data from a free-falling microstructure profiler (MSS) from Sea&Sun Technology, ship Acoustic Doppler Current Profiler (ADCP) data that show current velocities in the upper 40 m of the water column and moored ADCPs showing the lower 100 m of the water column.\r\n\r\nMidwater echo sounders permit remote observations of changes in the water column, including turbulence microstructure, thermohaline stratification, and suspended particles, as well as individual fish, fish schools, and zooplankton.\r\n\r\nThe microstructure profiler (MSS) provides oceanographic data from two shear probes (from which energy dissipation rates are inferred), two fast FP07 thermistors as well as conductivity, oxygen, turbidity, and depth.\r\n\r\nData were collected with R\/V Electra.","url":"http:\/\/bolin.su.se\/data\/muchowski-2023-aland-sea-2019-2020-1","keywords":["Marine","Observations","Turbulent mixing","Diapycnal Mixing","Broadband acoustic observations","R\/V Electra","Microstructure profiler","Simrad EK80","\u00c5land Sea","Baltic Sea","Stratified Overflow","Earth science > Oceans > Ocean acoustics"],"creator":{"@type":"Person","name":"Julia C.
