applications. In August 2018, the companies participated in the US Navy’s Advanced Naval Technology Exercise, an annual invitation-only event that was created by the U.S. Navy to see the future of naval technology in action today.Karl Kenny, Kraken’s President and CEO, said, “Seafloor mapping is one of the oldest professions known to humankind. For thousands of years, mariners have been measuring the seabed under their vessels. Today’s ocean surveying market is valued at over US$3 billion per year. Kraken’s customers have requested a high speed, ultra-high resolution

vehicles (ROV) and unmanned surface vehicles (USV).UMVs can range from very small vessels to that of a mid-sized ship or small submarine and are equipped with a variety of mapping, communications and navigation sensors. These systems are used in multiple applications such as naval mine detection, seafloor mapping, underwater asset infrastructure inspection, environmental characterization and others.Kraken President & CEO, Karl Kenny (Photo: Eric Haun)“The global UMV market is experiencing significant growth and investment in both military and commercial markets,” said Karl Kenny, Kraken&rsquo

Typically, SSS presents a “gap” in the coverage it offers, as in Figure 4.  This gap, or “Nadir” separates the left side sonar from the right to avoid interference.Because DOLPHIN enables transmission

These capabilities enable the precise control required for remotely operated vehicles, CTD casts, mooring deployments, and other operations required for science.The vessel's scientific equipment includes a seafloor mapping system, a knuckle crane that enables the vessel to deploy and recover autonomous vehicles, a stern A-frame with hydraulic hoist, a hand-deployable remotely operated vehicle, a hull-mounted transducer for underwater communications, and ample facilities for securing and integrating a wide variety

many science missions including under-ice work in the Arctic and oceanography in the Antarctic. A key program supported by these vehicles, sponsored by the Office of Naval Research (ONR), was known as the Autonomous Ocean Sampling Network. This pioneered designs for docking AUVs. Experiments in seafloor mapping and mine hunting were also conducted during the first ten years of the AUV Lab. In 1997 Bluefin Robotics was founded to transition these ideas into industry, the first of many commercial AUV manufacturers to follow.The Odyssey technology developments touched upon all domains. The core developments

Previous interns have worked on cruises to support science projects ranging from chemical oceanography, marine biology, GIS/bathymetric surveys (seafloor mapping), geological studies, work with ROVs and much more! The position will last approximately six months and the intern will receive a stipend of $500 per week, plus reimbursement for travel expenses and housing - mostly aboard one of the research vessels. Many successful internships result in a

Taani will have a range of greater than 5,000 nautical miles, with berths for 16 scientists and 13 crew members, a cruising speed of 11.5 knots and a maximum speed

Ocean Discovery XPRIZE Finalists to Compete off Greece

XPRIZE competition, which challenges teams to advance ocean technologies for rapid, unmanned and high-resolution ocean exploration and discovery.In this final field-testing round starting in November and running through December, finalists competing for the $4 million grand prize will put their seafloor mapping technologies to a real-world test off Kalamata, Greece.Each team will launch and recover their autonomous underwater technologies from XPRIZE’s Mission Control in Kalamata. The competition area is approximately 500 km2 and includes a number of underwater features. Finalist teams have to

Alumni Team, USV Maxlimer is based on a brand new USV called SEA-KIT, which can carry a deployable and retrievable payload of up to 2.5 tons – in this case, a Hugin AUV from Kongsberg Maritime. It’s a unique AUV-USV concept, designed to enable more efficient, safer and cost-effective seafloor mapping operations, as well as providing a platform for numerous applications in a wide range of maritime sectors.The SEA-KIT vessel itself provides a next generation, long-range, long-endurance ocean capability that is not available today. It is able to operate without assistance for months at a time
