TL;DR: Seagliders are small, reusable autonomous underwater vehicles designed to glide from the ocean surface to a programmed depth and back while measuring temperature, salinity, depth-averaged current, and other quantities along a sawtooth trajectory through the water as mentioned in this paper.
Abstract: Seagliders are small, reusable autonomous underwater vehicles designed to glide from the ocean surface to a programmed depth and back while measuring temperature, salinity, depth-averaged current, and other quantities along a sawtooth trajectory through the water. Their low hydrodynamic drag and wide pitch control range allow glide slopes in the range 0.2 to 3. They are designed for missions in a range of several thousand kilometers and durations of many months. Seagliders are commanded remotely and report their measurements in near real time via wireless telemetry. The development and operation of Seagliders and the results of field trials in Puget Sound are reported.

TL;DR: A new remotely operated underwater vehicle (ROV) designed to serve as a platform for rapid development and deployment of novel underwater vehicle systems and to enhance the ability to develop new underwater vehicle subsystems in the laboratory, and rapidly field-test these new systems.
Abstract: This paper reports the development of a new remotely operated underwater vehicle (ROV) designed to serve as a platform for rapid development and deployment of novel underwater vehicle systems. The goal is to enhance our ability develop new underwater vehicle subsystems in the laboratory, and rapidly field-test these new systems. Although a significant fraction of ONR and NSF sponsored underwater vehicle research is now directed towards AUVs, we argue that ROVs continue to provide a highly efficient platform for the research and development of advanced underwater technology. Once developed and validated on ROVs, numerous technologies have been readily transitioned for use in autonomous underwater vehicles (AUVs). Section 1.1 examines several contexts in which ROVs have served as development platforms for critical AUV technology. Section 1.2 reviews the desired performance specifications for the new vehicle.

TL;DR: The development of a prototype miniature low-cost autonomous underwater vehicle (AUV) was designed to explore technology for one-way military applications, including minefield mapping/tagging, and cooperative underwater activities with similar units, but could also find application in shallow water mapping and remote sensing.
Abstract: We announce the development of a prototype miniature low-cost autonomous underwater vehicle (AUV). The vehicle was designed to explore technology for one-way military applications, including minefield mapping/tagging, and cooperative underwater activities with similar units, but could also find application in shallow water mapping and remote sensing. The prototype vehicle measures approximately 24 inches long (61 m) by 3.5 inches in diameter (8.9 cm), displacing approximately 7 lbs (3.3 kg). We present the physical design of this vehicle, our findings from initial testing, including the performance of inexpensive sensors used for vehicle navigation.

TL;DR: Chemical detection underwater is playing increasingly important roles for both military and environmental applications, and use of unmanned underwater vehicles as sensor platforms allow extended ranges and greater area coverage with minimal risk to personnel and high-value assets.
Abstract: : Chemical detection underwater is playing increasingly important roles for both military and environmental applications. Use of unmanned underwater vehicles as sensor platforms allow extended ranges and greater area coverage with minimal risk to personnel and high-value assets. There are a variety of underwater platform types available including remotely operated vehicles (ROVs), autonomous underwater vehicles (AUVs), and crawlers. The benefits and tradeoffs of each platform type will be discussed with regard to the specific mission and environments. ROVs are the most mature of the platforms, with a wide range of systems in use in the Fleet and commercially. AUVs are becoming available and will provide extended capabilities in the future. State of the art systems and directions will be presented.
