Exocetus Delivers Glider to Johns Hopkins APL

Connecticut-based Exocetus Autonomous Systems said it has delivered its first MOD2 Glider to Johns Hopkins University Applied Physics Laboratory (APL). The vehicle was purchased as part of an internal research and development project which intends to explore a diverse set of applications for the vehicle.“Johns Hopkins APL was looking for a vehicle that could provide endurance and easy modification, and the MOD2 Glider was the only vehicle out there that provided those capabilities,” said Joe Turner, Exocetus COO & General Manager.    The delivery took place at the end of July

Wave Gliders to Study Arctic and Southern Oceans

robots called Wave Gliders as a sensor platform to conduct advanced scientific research in inhospitable and remote regions of the Arctic and Southern Oceans.Using Liquid Robotics’ wave and solar powered Wave Gliders, scientists from Scripps Institution of Oceanography (Scripps) and the Applied Physics Laboratory of the University of Washington (APL-UW) will obtain real time data and rare insights into the dynamic conditions that drive the world’s weather and climate. This data is critical for scientists to understand and improve global ocean weather modeling and climate prediction.The oceanographe

periods. Some supply continuous real-time data via a cable connection to shore.   A prime example is the Cabled Array in the NE Pacific Ocean. This observatory is part of the Ocean Observatories Initiative (OOI), funded by the US National Science Foundation (NSF). Engineered by the Applied Physics Laboratory / University of Washington (APL / UW), the Cabled Array uses dedicated telecoms cables. They provide a high voltage supply and high-speed communication links to nodes as far as 500 km from shore.   Besides its high-tech infrastructure, the Cabled Array holds 150 instruments. Included

Riptide looks to outfit a growing market: smaller UUVs   Unmanned undersea vehicles (UUVs) trace their history to the Special Purpose Underwater Research Vehicle (SPURV) developed by the University of Washington’s Applied Physics Laboratory in 1957. While the UUV was conceived decades ago it was the remotely operated undersea vehicle (ROV) market, with offshore oil and gas providing a significant driver, which initially saw significant technical and product developments.    It was not till the late 1980s and early 1990s, that UUVs began to be noticed again.   New

The National Oceanic and Atmospheric Administration, the National Science Foundation, the National Ice Center, Space and Naval Warfare Systems Command, the University of Cambridge (U.K.) and the University of Washington’s Applied Physics Laboratory will provide personnel, unmanned technologies and resources to help the RDC better understand how a simulated oil spill moves in the water near the ice edge over a 48-hour period. Alaska Department of Environmental Conservation will have an observer aboard for this effort as well. &ldquo

Huge Waves Measured for First Time in Arctic Ocean

waves during a September 2012 storm. The results were recently published in Geophysical Research Letters. "As the Arctic is melting, it's a pretty simple prediction that the additional open water should make waves," said lead author Jim Thomson, an oceanographer with the UW Applied Physics Laboratory . His data show that winds in mid-September 2012 created waves of 5 meters (16 feet) high during the peak of the storm. The research also traces the sources of those big waves: high winds, which have always howled through the Arctic, combined with the new reality of open water in summer

DeepWater Buoyancy Chosen for Ocean Observatories Initiative

DeepWater Buoyancy has been awarded a major contract to supply flotation to the University of Washington’s Applied Physics Laboratory for the cabled observatory component of the Ocean Observatories Initiative (OOI). The OOI, a project funded by the National Science Foundation (NSF), is planned as an integrated infrastructure of science-driven platforms and sensor systems to measure physical, chemical, geological and biological properties and processes from the seafloor to the air-sea interface. The company was selected after a competitive bidding and assessment process that evaluated product

Under a contract issued to Boeing Research & Technology (BR&T), OceanGate, the Applied Physics Laboratory at the University of Washington (APL-UW) and Boeing have validated the basic hull design for a submersible vehicle able to reach depths of 3,000m.

Cyclops: A Revolutionary Hull Design

OceanGate Inc. announced the completion of the initial carbon fiber hull design and feasibility study for its next generation manned submersible – Cyclops. Under a contract issued to Boeing Research & Technology (BR&T), OceanGate, the Applied Physics Laboratory at the University of Washington (APL-UW) and Boeing have validated the basic hull design for a submersible vehicle able to reach depths of 3,000m. With its large 180-degree borosilicate glass dome, the new vehicle will offer a chance to examine the environment, collect samples, and deploy technology in subsea settings in person

Johns Hopkins University Orders Second Iver2 Research AUV

OceanServer Technology announced that the Johns Hopkins University Applied Physics Laboratory (APL) has agreed to purchase another Iver2 AUV for delivery this summer. This second system provides additional capability for APL’s general research, including the development of underwater sensor systems.   Founded in 1942, APL is a not-for-profit center for engineering, research and development, and solves complex problems that present critical challenges to the nation.   Johns Hopkins APL will be taking delivery of an Iver2 EP42 platform that includes a second (user) CPU and intuitive
