Three Decades of High Pressure for Lowered ADCPsIntroductionEver since the unexpected motions of the first deep-drifting floats, oceanographers have worked to lift the veil on deep currents. Direct current measurements have come in various guises. Neutrally-buoyant floats and their profiling offspring revealed deep pathways. Current meters on moorings showed changes in time. Free-falling probes allowed a profile view—closely-spaced measurements showing water current velocity versus depth. And lowered ADCPs (LADCP) have provided well-resolved, full-depth current profiles since the early 1990s.

Port of Antwerp Tests Autonomous Sounding Boat

Port of Antwerp has reached a new milestone with the introduction of a fully automatic sounding boat that employs unique technology. The vessel, named the Echodrone, is a prototype that is currently being developed to supplement the other operational sounding boat, the Echo.Both of these carry out measurements of the water depth everywhere in the port so as to guarantee safe passage for shipping. The cloud-based technology – a first – has been developed in partnership between the Port Authority and dotOcean and is only one of the many initiatives being taken by the Port Authority in the
