Uncharted Depths: Exploring the Marianas with SuBastian

the submersible Alvin was the first to visit the nearby Mariana Back-arc, a zone of highly active submarine volcanism and hydrothermal vents hidden 13,000 feet below the ocean’s surface. After returning to the Back-arc 30 years later equipped with the Schmidt Ocean Institute’s new underwater vehicle SuBastian, scientists can now fill gaps in our understanding about the biogeography of these unique ecosystems and to identify possible new species thriving in this extreme deep-ocean environment.    Volcanic Zones - Mariana Region The Mariana region is home to a subduction system &ndash

The new FlowQuest 600 Micro acoustic current profiler operates at 600 KHz. It is similar to the standard FlowQuest 600 acoustic current profiler in terms of functions and performance, but is much smaller and lighter. The FlowQuest 600 Micro current profiler is 13 cm in diameter and 21.0 cm in length, and weighs less than 1.6 kgs in water. It will mainly be used for inland discharge measurements but will also be useful for oceanographic applications when smaller size and lighter weight are beneficial.   LinkQuest manufactures high-speed, power-efficient and robust 38,400 baud underwater acoustic

Multinational Task for Australian Mine Warfare Team

Australia, New Zealand, the United States, and Britain converged on Bland Bay, New Zealand for Exercise FULCRUM recently.   The contingent had to locate and dispose of 16 dummy mines of varying shape, size and weight, set throughout the bay.   Australian and British autonomous underwater vehicle teams used remote environmental monitoring units to scan the bay floor and identify mine-like objects.   The US and New Zealand then sent out divers to confirm whether or not they were mines, said Lieutenant Teina Hullena of the Royal New Zealand Navy Clearance Diving Group.   "

Planck Aerosystems builds unmanned aerial systems (UAS) for maritime professionals. Based in San Diego, Planck was founded on the idea that putting an aircraft on every boat would represent a transformational change to maritime industry through improved data acquisition, situational awareness and safety. Planck has built the technology to make the dream of putting a drone on every boat a reality.  Founder Josh Wells and lead engineer Allan Matthew conducted a series of technology demonstrations during Oceanology International North America (OINA), held in San Diego February 14-16, 2017.

US Navy Tests UUV for Mine-hunting Operations

The General Dynamics Mission Systems Knifefish team completed a comprehensive evaluation of Knifefish, an autonomous surface mine countermeasure (SMCM) unmanned undersea vehicle (UUV). In coordination with the U.S. Navy, the test events took place off the coast of Boston using submerged Navy mine test targets. The evaluation represents a significant milestone in the Knifefish program and demonstrates the UUV’s capability to detect and classify potential mines, at a variety of depths, each posing a unique threat to naval vessels operating in a mission area.   “The information and

production systems are the order of the day. They are easier and less expensive to install. Even though an optical fiber weighs much less than a comparable copper wire, there are practical limits to how small a connector should be. A subsea wetmate connector that will be deployed by a remotely operated vehicle (ROV) must be large enough to be clearly seen by ROV cameras, and sufficiently robust to be mated/unmated without damage by ROV manipulators. In this case, ROV-mateable connectors may have generous lead-ins to guide the mating halves together.   Connecting Traditional Packaging to Subsea
