From: On the generation of internal waves by river plumes in subcritical initial conditions
Map of the study area off Douro River; (b) Douro River Plume (Sentinel 2A 16 Mar 2017); (c) IW generation at the plume front (green-channel); (d) Transect corresponding to the red line in (c) with evidence of 5 internal solitary waves between A′ and A″; (e) TerraSAR-X (German remote sensing synthetic aperture radar) image acquired on April 23, 2017. The reference AUV tracks (data showed in Fig. 2) are demonstrated by the green line. Image (b,c) processed using SNAP v6.0 (http://step.esa.int/main/download/snap-download/). Data of the image (d) were obtained through SNAP v6.0 and processed using Matlab (R2017a, https://www.mathworks.com/products/new_products/release2017a.html). Image (e) was processed using Matlab (R2017a). The figure composition and the image (e) were created in ArcGIS v10.5 (https://desktop.arcgis.com/en/quick-start-guides/10.5).
