Full-Depth Current Profiling Around the Global Ocean

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.

New F180 Lightweight Pre-Calibrated System

CodaOctopus unveiled a new F180 Lightweight Pre-Calibrated Housing designed for those who require a simpler, faster, more flexible solution for accurate marine positioning. This waterproof housing for the F180 and F180R series of GNSS aided inertial positioning devices fully integrates with CodaOctopus MOTION control to provide precise IMU to Antenna alignment without the need for calibration.This latest model is 25 percent smaller, more than 20 pecent lighter, and competitively priced, allowing customers to integrate their system faster and in more flexible ways than before, the manufacturer said.

NATO Uses IoT to Study the Oceans

of Oldenburg’s work monitoring plastic debris in the North Sea and Spain’s coastal authority, Salvamento Maritimo, using SPOT Trace to devise oil spill disaster recovery procedures. The National Institute of Oceanography and Experimental Geophysics and the “Istituto di Scienze Marine” of the Italian National Research Council use SPOT Trace to study surface currents in the Mediterranean and the University of Miami Rosenstiel School of Marine and Atmospheric Science has used large quantities of SPOT Trace satellite trackers also for oceanographic and oil spill research
