It’s hard to overstate the importance of our oceans. They cover nearly three-quarters of the globe, represent a major food source, and regulate our climate. By 2030, the Organization for Economic Cooperation and Development estimates ocean-based industries will generate $3 trillion of economic activity. But in a world where data has become critical to manage every challenge and ...
Repeated bathymetric surveys with a multibeam echosounder system reveal that the artificial supply of sediment provoked significant morphological changes in the dune field, including the infill of dune troughs and even the complete burial of individual dunes. ...
However, not even an echo-sounding frequency of 1 MHz can give a resolution better than a few millimeters, which is not always quite adequate (e.g., in areas of low intensity processes, plane bed transport, or when studying ephemeral mud blankets). Both the echosounder and the cameras are quite bulky and will disturb the flow pattern if they are put too close to the point of ...
