Ocean gliders are quiet, buoyancy-driven, long-endurance, profiling autonomous platforms. Gliders therefore possess unique advantages as platforms for Passive Acoustic Monitoring (PAM) of the marine environment. In this paper, we review available glider and passive acoustic monitoring systems, explore current potential uses monitoring-equipped study physical oceanography, biology, ecology regul...

Today, underwater acoustic communication is developing for its various applications. For signal transmission in underwater using ocean/ sea/lakes/rivers as a medium an appropriate underwater acoustic system is required. The significant characteristic of ocean makes the underwater communication difficult using electromagnetic waves. The characteristics of an acoustic signal make a good candidate...

We introduce for the first time a new product line able to make high accuracy measurements of number water chemistry parameters in situ : i.e., submerged environment including deep sea (to 6,000 m). This is based on developments lab chip technology at National Oceanography Centre (NOC), and University Southampton produced under license by Clearwater Sensors Ltd., start-up industrial partner bri...

Abstract. Ocean gliders enable us to collect the high-resolution microstructure observations necessary calculate dissipation rate of turbulent kinetic energy, ε, on timescales weeks months: far longer than is normally possible using traditional ship-based platforms. Slocum have previously been used this end; here, we report first detailed estimates ε calculated Batchelor spectrum method collect...

During the 1990s, numerous worldwide research and development activities have occurred in underwater robotics, especially in the area of autonomous underwater vehicles (AUVs). As the ocean attracts great attention on environmental issues and resources as well as scientific and military tasks, the need for and use of underwater robotic systems has become more apparent. Great efforts have been ma...

In the world of underwater robotics, fish-like structures are able to accelerate and maneuver better than most other artificial underwater vehicles. For these reasons, fish-like robots are well suited for submarine exploration tasks. However, a complete understanding of mechanisms governing the swimming movements of fish-like robots remains elusive, limiting the performance of such underwater r...

In recent years underwater robotics has become a major area of research owing to the development of many diverse technologies. Autonomous underwater vehicles (AUVs) are used today for exploration, pipeline monitoring, military reconnaissance and other scientific tasks. AUVs can also be used effectively to teach principles in many disciplines of science ranging from physics to robotics. Any good...

Underwater robotics addresses the problem of object detection apparatus. Offers a probabilistic formulation of the problem, which uses the reduction of the detection task to a classical task of Buffon. This formulation arises naturally in the formulation of the problem in the coordinate system associated with the apparatus. It is shown that the problem allows analysis in the presence of an asym...
