A high-density genetic map is essential for quantitative trait locus (QTL) fine mapping. In this study, 4,508 effective single nucleotide polymorphism markers (detected using specific-locus amplified fragment sequencing) and 475 microsatellites were mapped to 19 linkage groups (LGs) using a family with ...
This paper presents our preliminary geoacoustic inversion results of the ship noise data collected by a vector sensor in 2008, Dalian, China. For the at-sea measurement, a fishing boat was served as a passive source passed by the receiver boat deploying a vector sensor, which collected the pressure ...
We have constructed an algorithm that is able to classify generic sonar objects as divers or not divers. This process was made difficult by the fact that human divers produce amorphous blobs when ensonfied with 2D imaging sonar, which makes it difficult to use state-of-the-art Computer Vision classification ...
This paper presents a novel scheme for the three-dimensional (3D) reconstruction of underwater objects by using multiple acoustic views based on geometric and image processing approaches. Underwater tasks such as maintenance, ship hull inspection, and harbor surveillance require accurate underwater ...
Modern electronic devices are constructed using a large palette of materials, some of which are considered “critical,” meaning that their supply-chains are tenuous to some degree and they cannot easily be substituted. The rare earth crisis of 2010–'11 brought worldwide attention to the challenge of ...
This research investigates the management functions and skills required for co-operative development within the agri-business value chain in South Africa. The study was conducted in Mpumalanga province within South Africa. The province spent close to ZAR50 million through the Comprehensive Rural Development ...
The need for inspection of subsea infrastructures - ranging from ship hulls to pipelines - have led to development of various underwater vehicles specifically geared towards such missions. One such example is the EVIE (Ellipsoidal Vehicle for Inspection and Exploration) robot developed by the d'Arbeloff ...
With recent developments in battery technology and ocean energy harvesting systems, biological fouling, or biofouling, a process referring to the gradual accumulation of organisms on underwater surfaces, has gained a foothold as the primary adversary in long-duration autonomous underwater vehicle (AUV) ...
The accelerated life test (ALT) is a tool used by cable manufacturers and cable end-users to determine how long a given piece of hardware will last once deployed into the marine environment. To conduct an ALT, the failure mechanism for the hardware in question must be known, and the kinetics of that ...
This paper presents the details of the development of an underwater camera for monitoring the habitats of red snow-crabs. Because the red snow crabs inhabit the deep waters in the east sea of South Korea, where the depth is approximately between 1,000 m and 1,800 m, and underwater camera that can endure ...
IN THIS presentation we will argue that Big Data technologies can contribute in an important way to an unprecedented breakthrough in the understanding of oceans as a factor in climate change, in transportation, and in supplying humanity with its important food component.
A pod is a propeller propulsion device installed externally to the ship's hull. The pod system comprises a short propulsion shaft, on which the propulsion electric motor is mounted. In most cases, propulsion is achieved by means of fixed pitch propellers powered by an AC synchronous motor (conventional, ...
Marine pollution by antifouling paints is becoming a serious environmental problem due to anthropogenic activities. Antifouling paints have a very harmful efect not only on marine organisms but also, through the food chain, on humans. Although the ban on tributyltin (TBT) has resulted in significant ...
There are only vague ideas on what social innovations actually are, how they evolve and how they work in comparison to technical understandings of innovation management. In a comparative analysis of two case studies of two non-profit organizations advancing social innovation in Germany we investigate ...
The Alaska Ocean Observing System (AOOS) is the Integrated Ocean Observing System (IOOS) Regional Association (RA) responsible for coordinating statewide monitoring for Alaska's nearly 44,000 miles of coastline and offshore environments. The Alaska coastline is larger than that of any other RA territory ...
The National Oceanic and Atmospheric Administration (NOAA) employs many technologies in its diverse missions. NOAA challenges include monitoring the atmosphere and predicting the weather, charting the Nation's waterways, protecting marine sanctuaries, managing fisheries resources and exploring and understanding ...
Understanding the marine soundscape is of growing importance to the National Marine Sanctuaries. In the center of Monterey Bay National Marine Sanctuary, a new Passive Acoustic Monitoring (PAM) project has begun. Using the power and communications infrastructure of the Monterey Accelerated Research ...
The Wave Glider is a unique wave and solar energy powered Unmanned Surface Vessel (USV). Its two-part design makes it well suited for towing instruments at depth. Deploying a towed payload from a Wave Glider results in a three body, two tether, configuration. Technical considerations for towing payloads ...
The Texas coast represents an area of interest for a wide variety of stakeholders, including the oil industry (for both, exploration and operation purposes), fisheries and living resource management, ecosystem, coastal hazard mitigation and planning, and ocean and coastal education. For more than twenty ...
This paper presents a novel integrated approach of creating a 3-D surface map of seabed terrain using an Autonomous Underwater Vehicle (AUV) equipped with various sensors such as multi-beam sonar sensors, DVL, and IMU. The underwater terrain map is useful for various applications like fishery, search ...
