This paper describes the development of the Unmanned Port Security Vessel (UPSV), a small autonomous surface vehicle designed to support maritime domain awareness in port and harbor environments. The UPSV is capable of rapidly producing fine resolution, shallow-water bathymetry maps using a multibeam sonar, detecting chemical threats using an on board mass spectrometer and monitoring oceanographic parameters using off-the-shelf instruments.

The design, testing, and mission execution of a network of autonomous underwater vehicles (AUV) is a difficult process. The design of low-level controllers requires high-fidelity hydrodynamic models for simulation, but the testing of a large network of AUVs with high-order models is computationally challenging. Also, efficiency is achieved when developers can reuse components already implemented and tested by others in the community. An integrated development system is discussed where the Robot Operating System (ROS) is used to interface a number of individual systems that could not natively communicate. The system integrates the low-level controller simulation, mission planning, and mission execution processes. Most importantly, ROS was integrated with the Mission Oriented Operating Suite (MOOS), which allowed for the use of both ROS and MOOS applications within the same robotic platform via the MOOS/ROS Bridge application. Also, the 3D globe mapping program, NASA WorldWind, was interfaced to ROS via rosjava. The target AUV for the ROS implementation was the GTRI Yellowfin, which was developed for multiple AUV collaborative missions.

President Barack Obama announced, in April 2009, the completion of the Final Renewable Energy Framework to govern the management of the Outer Continental Shelf (OCS) Renewable Energy Program. Examples of the general types of renewable energy project activities the Bureau of Ocean Energy Management, Regulation and Enforcement (BOEMRE) has the discretion to authorize include, but are not limited to: wind energy, wave energy, ocean current energy, solar energy and hydrogen production. The BOEMRE is actively implementing the program in the Atlantic and Pacific OCS Regions. In July 2011, Secretary of the Interior Ken Salazar agreed to establish a BOEMRE-Hawaii OCS Renewable Energy task force and to work collaboratively to identify appropriate opportunities for research and commercial renewable energy leasing on the OCS off Hawaii. The BOEMRE has begun to work closely with state and federal agencies and local government representatives to plan and coordinate the implementation of the program in Hawaii.)

This paper introduces a new type of kinetic hydropower generator, ideally suited to relatively small shallow rivers and channels. The design utilizes rectangular hydroplanes (‘sails’) moving around the device. The device extracts energy from a flow of water using an elongated vertical axis turbine, where a series of sails are mounted between two belts at the top and bottom of the device, rotating in the horizontal plane.

The optical properties of both phytoplankton and zooplankton were investigated in this study. The absorption spectrums of planktons were measured using an UV-visible spectrophotometer. An absorption peak was found at 670 nm for the phytoplankton. A particle detecting system for an optical plankton counter (OPC) was designed and built with a red LED as a light source based on the optical characteristics of plankton. In order to observe underwater environment, the embedded system was developed. The autonomous float is controlled by embedded system composed of field-programmable gate array (FPGA) and CPU to perform image signal processing, data compression, power management and satellite communication. Embedded system acquires high-resolution particle image using a linear-CCD for counting particles in underwater environment. On-board signal processing reduces amount of particle image data for good performance in satellite communication. Using OPC and the embedded system, scanning images of brine shrimp was acquired.

This paper proposes a new normal mode algorithm based on Finite-Difference Time-Domain (FDTD) scheme. The proposed method can efficiently predict the wideband path-loss of the underwater acoustic channel through only one simulation, while the conventional normal mode theory based on frequency-domain analysis should be repeated many times over wideband frequency points. To validate the proposed method, a 40% bandwidth at 20 Hz has been simulated using a Gaussian pulse excitation and compared with the known normal mode solution, the Kraken, and the ray theory solution, the Bellhop.

This paper discusses opportunities to parallelize graph based path planning algorithms in a time varying environment. Parallel architectures have become commonplace, requiring algorithm to be parallelized for efficient execution. An additional focal point of this paper is the inclusion of inaccuracies in path planning as a result of forecast error variance, accuracy of calculation in the cost functions and a different observed vehicle speed in the real mission than planned. In this context, robust path planning algorithms will be described. These algorithms are equally applicable to land based, aerial, or underwater mobile autonomous systems. The results presented here provide the basis for a future research project in which the parallelized algorithms will be evaluated on multi and many core systems such as the dual core ARM Panda board and the 48 core Single-chip Cloud Computer (SCC). Modern multi and many core processors support a wide range of performance vs. energy tradeoffs that can be exploited in energy-constrained environments such as battery operated autonomous underwater vehicles. For this evaluation, the boards will be deployed within the Slocum glider, a commercially available, buoyancy driven autonomous underwater vehicle (AUV).

Underwater vehicles have recently become more useful in ecological monitoring, largely in part to advanced processing capabilities enabled by modern computers. Most underwater vehicles are torpedo shaped and non-holonomically controlled, which makes them efficient, but they lack precise maneuverability. Some cube-shaped vehicles are used when more exact navigation is necessary; however they cannot take advantage of gliding motions and hydrodynamic lift as their vehicles have a large amount of drag. The Stingray Autonomous Underwater Vehicle (AUV) is a compact, lightweight AUV with a unique design implementation. The hull of the Stingray is a carbon fiber shell with a biomimetic design reminiscent of its ocean-dwelling namesake. This streamlined profile provides very low drag and allows the vehicle to glide through the water. The Stingray also uses a unique propulsion system, combining three vertical thrusters on the wings and tail for roll and pitch with two Voith-Schneider propellers mounted underneath for yaw and surge. In addition, these two propellers provide the ability to strafe, allowing the vehicle to move with six degrees of freedom. This enables the Stingray to easily maneuver at slow speeds and hover in a similar fashion to a helicopter, while also being able to take advantage of the lift generated by its wings to glide like a fixed-wing aircraft.

The hydraulic power takeoff converter has been commonly applied to the rotating body type wave energy converters. It is because the hydraulic converter is more suited for dealing with periodic oscillating property of the body in a cost effective way. In order to extract wave energy effectively, the pressure and flow rate of the working fluid in the hydraulic converter should be kept adequately reflecting the period and height of given ocean wave. The pressure and the flow rate of the working fluid have effects on providing desired phase between incident wave and rotating body, and achieving optimum amplitude for the rotating body, respectively. To accomplish these objects together, a flexible controller is required reflecting the large variety of real ocean wave conditions. If the desired flexibility is limited, this may seriously affect the energy absorbing efficiency. The controller is designed to maintain the pressure and the flow rate of the working fluid at an optimum condition according to the given incident waves.

The U.S. Integrated Ocean Observing System (IOOS®) partners have begun an effort to extend the use of high frequency (HF) radar for U.S. Coast Guard (USCG) search and rescue operations to all U.S. coastal areas with HF radar coverage. This project builds on the success of an IOOS and USCG-supported regional USCG search and rescue product created by Applied Science Associates (ASA), Rutgers University and University of Connecticut for the mid-Atlantic region. We describe the regional product and the expanded national product's two main components: optimally-interpolated velocity fields and a predicted velocity field.
