Winds, Waves, and Bubbles at the Air-Sea Boundary
JEFFREY L. HANSON WINDS, WAVES, AND BUBBLES AT THE AIR-SEA BOUNDARY Subsurface bubbles are now recognized as a dominant acoustic scattering and reverberation mechanism in the upper ocean. A better understanding of the complex mechanisms responsible for subsurface bubbles should lead to an improved prediction capability for underwater sonar. The Applied Physics Laboratory recently conducted a unique experiment to investigate which air-sea descriptors are most important for subsurface bubbles and acoustic scatter. Initial analyses indicate that wind-history variables provide better predictors of subsurface bubble-cloud development than do wave-breaking estimates. The results suggest that a close coupling exists between the wind field and the upper-ocean mixing processes, such as Langmuir circulation, that distribute and organize the bubble populations. INTRODUCTION A multiyear series of experiments, conducted under the that, in the Gulf of Alaska wintertime environment, the auspices of the Navy-sponsored acoustic program, Crit amount of wave-breaking activity may not be an ideal ical Sea Test (CST), I has been under way since 1986 with indicator of deep bubble-cloud formation. Instead, the the charter to investigate environmental, scientific, and penetration of bubbles is more closely tied to short-term technical issues related to the performance of low-fre wind fluctuations, suggesting a close coupling between quency (100-1000 Hz) active acoustics. One key aspect the wind field and upper-ocean mixing processes that of CST is the investigation of acoustic backscatter and distribute and organize the bubble populations within the reverberation from upper-ocean features such as surface mixed layer. waves and bubble clouds. -
Wetsuits Raises the Bar Once Again, in Both Design and Technological Advances
Orca evokes the instinct and prowess of the powerful ruler of the seas. Like the Orca whale, our designs have always been organic, streamlined and in tune with nature. Our latest 2016 collection of wetsuits raises the bar once again, in both design and technological advances. With never before seen 0.88Free technology used on the Alpha, and the ultimate swim assistance WETSUITS provided by the Predator, to a more gender specific 3.8 to suit male and female needs, down to the latest evolution of the ever popular S-series entry-level wetsuit, Orca once again has something to suit every triathlete’s needs when it comes to the swim. 10 11 TRIATHLON Orca know triathletes and we’ve been helping them to conquer the WETSUITS seven seas now for more than twenty years.Our latest collection of wetsuits reflects this legacy of knowledge and offers something for RANGE every level and style of swimmer. Whether you’re a good swimmer looking for ultimate flexibility, a struggling swimmer who needs all the buoyancy they can get, or a weekend warrior just starting out, Orca has you covered. OPENWATER Swimming in the openwater is something that has always drawn those types of swimmers that find that the largest pool is too small for them. However open water swimming is not without it’s own challenges and Orca’s Openwater collection is designed to offer visibility, and so security, to those who want to take on this sport. 016 SWIMRUN The SwimRun endurance race is a growing sport and the wetsuit requirements for these competitors are unique. -

The U.S. Navy is adapting by continuing its blue-water dominance while simultaneously building brown-water ca- pabilities. Unmanned systems, such as unmanned airborne drones, are proving piv- otal in facing new battlefield challenges. Unmanned underwater vehicles (UUVs) are emerging as the Navy's seaborne equivalent of the Air Force's drones. Representing a low-end disruptive technology relative to traditional shipborne operations, UUVs are becoming capable of taking on increasingly complex roles, tipping the scales of battlefield entropy. They improve mission outcomes and operate for a fraction of the cost of traditional operations. -

Sonar for Environmental Monitoring of Marine Renewable Energy Technologies
Sonar for environmental monitoring of marine renewable energy technologies FRANCISCO GEMO ALBINO FRANCISCO UURIE 350-16L ISSN 0349-8352 Division of Electricity Department of Engineering Sciences Licentiate Thesis Uppsala, 2016 Abstract Human exploration of the world oceans is ever increasing as conventional in- dustries grow and new industries emerge. A new emerging and fast-growing industry is the marine renewable energy. The last decades have been charac- terized by an accentuated development rate of technologies that can convert the energy contained in stream flows, waves, wind and tides. This growth ben- efits from the fact that society has become notably aware of the well-being of the environment we all live in. This brings a human desire to implement tech- nologies which cope better with the natural environment. Yet, this environ- mental awareness may also pose difficulties in approving new renewable en- ergy projects such as offshore wind, wave and tidal energy farms. Lessons that have been learned is that lack of consistent environmental data can become an impasse when consenting permits for testing and deployments marine renew- able energy technologies. An example is the European Union in which a ma- jority of the member states requires rigorous environmental monitoring pro- grams to be in place when marine renewable energy technologies are commis- sioned and decommissioned. To satisfy such high demands and to simultane- ously boost the marine renewable sector, long-term environmental monitoring framework that gathers multi-variable data are needed to keep providing data to technology developers, operators as well as to the general public. Technol- ogies based on active acoustics might be the most advanced tools to monitor the subsea environment around marine manmade structures especially in murky and deep waters where divining and conventional technologies are both costly and risky. -
