, $8 million project to place two turbines on the sea floor off Whidbey Island.The project was terminated in 2014, six months after the Federal Energy Regulatory Commission had given a green light to install the turbines.The PUD had been working with local, state and federal agencies, the University of Washington, research labs and others, but progress stalled under ballooning costs and disagreements with the DOE.When the DOE decided not to fund a full 50% of the project, the PUD announced that it could not move forward without that funding.Surrounded by tidal races 160 miles north of San Juan County

community in the USA and Canada to share insights, experiences and how its GNSS-A and AZA instruments can be further improved to meet future needs.These included; Ocean Networks Canada, U.S. Geological Survey (USGS), Georgia Institute of Technology, Woods Hole Oceanographic Institution and the University of Washington, as well as our hosts Scripps Institution of Oceanography in California. As well as providing the stunning backdrop for this event, Scripps Institution of Oceanography furnished instruments for the workshop from the large pool of our equipment.GNSS-A and AZA are two independent technologies

. Science instruments like the WIMBO are individual components of a greater project, the Arctic Mobile Observing System (AMOS), a network of robotic oceanographic instruments making years-long autonomous observations of ocean and sea ice physics.The science party, headed by Dr. Craig Lee of the University of Washington’s Applied Physics Laboratory is comprised of the foremost leaders in the field of oceanographic science.“The ONR AMOS program focuses on developing technologies for making continuous, long-term scientific observations of the Arctic marine environment,” said Lee. &ldquo

Back to the Future: Blended Wing Gliders Could Redefine Undersea Warfare

magazine article, the underwater glider has become a mainstay of ocean scientific research. The Teledyne Marine Slocum glider(named for Joshua Slocum, the first to solo circumnavigate the globe in a sailboat),along with its cousins the Kongsberg SeaGlider, originally developed by the University of Washington, and Spray Glider, jointly developed by Woods Hole and Scripps Institute of Oceanography, have been at the forefront of the marine robotics revolution. Gliders are unique among autonomous underwater vehicles (AUVs). Rather than use thrusters or propellers for propulsion, they rely on changes

involves developing and demonstrating modular optical camera systems, imaging sonar software, an instrument integration hub, and an automated, cloud-based data management system to create lower-cost instrumentation and user-friendly environmental monitoring tools. These tools are based on the University of Washington’s Adaptable Monitoring Package, which has been tailored for long-term monitoring at marine energy sites.Subseasail, California, is working on ASGUARD, an "Advanced Sea Going and Underwater Autonomous Research Device".

NOC-led Study Paves the Way for Future Climate Models

(NOC) has led a study to investigate gaps in knowledge of the biological carbon pump, in the hope of prioritizing which aspects should be included in future climate model developments, and the observations necessary to achieve that. The study, which was carried out with the Imperial College, University of Washington, University of Bern and Boston College is aiming to pave the way for more accurate modelling of future ocean carbon storage.Climate models aim to inform us about how the world will respond to climate change caused by increasing carbon dioxide in the atmosphere. A critical part of the Earth&rsquo
