New Research on Gulf of Mexico Loop Current

More than $10 million in grant funding has been awarded for a group of new projects that aim to fill research gaps in order to help improve understanding and prediction of the Gulf of Mexico Loop Current System (LCS).As the Gulf of Mexico's dominant ocean circulation feature, the LCS has far-reaching implications for a wide range of human and natural systems, including oil and gas operations, yet knowledge about the underlying dynamics that control its behavior is limited.Following recommendations from a National Academies of Sciences, Engineering, and Medicine (NASEM) report released earlier this

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.

Acteon Acquires Deepwater Corrosion Services

Acteon Group Ltd has acquired subsea corrosion specialist Deepwater Corrosion Services Inc. in a move to strengthen the group's ability to help customers manage the integrity of subsea infrastructure throughout the life of a field.Deepwater has designed, built and installed more offshore cathodic protection systems than any other company and provides corrosion investigation and subsea inspection services. It operates from facilities in the U.S., the U.K., Brazil, Norway and Australia.Acteon said the acquisition broadens its technical knowledge of corrosion engineering, problem solving and retrofit

ROVs and Surveying Harbor Pollution

Norway’s Agder Dykk, is extending its scope of operations in the region with a new Saab Seaeye Falcon.An early task for Agder Dykk’s Falcon is a survey of Norway’s harbors to provide data for the authorities on the status of sediment built up over decades of environmentally polluting activities.In addition to this task, Agder Dykk will extend itsFalcon’s role across a wide scope of operations in the region to include multibeam survey, construction work support and inspection of cables, pipes and moorings, together with inspection of infrastructure for the Norwegian authorities.

Sea Level Variation Study Using GPS and an Ice Profiling Sonar

Dr. David Holland of New York University, in collaboration with Dr. Natalya Gomez at McGill University, is leading an investigation of sea level variations in the Disko Bay region of western Greenland.  A shore-based system compares the direct arrival of GPS signals to the signals reflected off the sea surface to obtain sea level. The presence of sea ice and icebergs complicate the measurements. A shore-mounted camera provides information about the surroundings and the presence of sea ice and icebergs when there is daylight.  Underwater sonar devices can supplement the camera-based
