2. 1. Uncovering Ocean Mixing near Rough Bathymetry : Using Broadband Acoustics

   Author : Julia C. Muchowski; Christian Stranne; Martin Jakobsson; Lars Umlauf; Lars Arneborg; Fer Ilker; Stockholms universitet; []
   Keywords : NATURVETENSKAP; NATURAL SCIENCES; ocean mixing; diapycnal mixing; broadband acoustics; turbulence microstructure; rough bathymetry; stratified flow over obstacles; observations of turbulent mixing; Baltic Sea research; maringeologi; Marine Geology;

   Abstract : Ocean mixing related to rough bathymetry is highly dynamic and exhibits large spatial and temporal variability. Therefore, established in-situ methods as well as numerical models often lack the resolution to capture this type of mixing. In this thesis, acoustics are used to observe, map and quantify stratified mixing at unprecedented resolution. READ MORE

4. 2. Spiritum sidus : The star of our life – On internal tides in the ocean

   Author : Gaspard Geoffroy; Jonas Nycander; Christian Stranne; Aurélien Ponte; Stockholms universitet; []
   Keywords : NATURVETENSKAP; NATURAL SCIENCES; Internal waves; Tides; Argo floats; Time series analysis; Flow-topography interaction; Atmospheric Sciences and Oceanography; atmosfärvetenskap och oceanografi;

   Abstract : Tidal currents flowing over rough bathymetry generate internal tides. These internal waves with tidal frequency can be decomposed into vertical modes. Low modes generally travel thousands of kilometers, until they break due to shear flow instabilities, while high modes are believed to break close to the generation site. READ MORE
