Data and models show that Alaska waters are highly vulnerable to low saturation states of aragonite, an indicator of increasing ocean acidification conditions for this high-latitude region. With Alaskans heavily reliant on the ocean for their lives and livelihoods, both direct and indirect effects of ...
Nowadays, ocean observatory networks, which gather and provide multidisciplinary, long-term, 3D continuous marine observations at multiple temporal spatial scales, play a more and more important role in ocean investigations. In this paper, we try to develop a portable smart device with online fish detection ...
Studying fish recognition has important realistic and theoretical significance to aquaculture and marine biology. Fish recognition is challenging problem because of distortion, overlap and occlusion of digital images. Previous researchers have done a lot of work on fish recognition, but the classification ...
The development of revolutionary tools such as AUVs and other unmanned vehicles has offered oceanographers a chance to explore areas that are not easily accessible and address questions that have yet to be answered. The ability of unmanned vehicles to reach these under-sampled parts of the ocean is ...
Fish-as-a-Service (FaaS) is a business-to-business model offering monitoring services performed by a biomimetic fishlike drone. FaaS considers environmental, scientific, and business concerns when addressing marine monitoring, providing alternative methodology while preserving ocean resources. The key ...
A software tool has been developed to simulate the entanglement of leatherback sea turtles (Dermochelys coriacea) in fishing and aquaculture gear. Entanglements are well documented and are increasing in frequency due to greater fishing effort and with the use of synthetic materials in marine applications. ...
Marine aquaculture is deeply rooted in Norwegian national economics and traditions, especially in the MØre og Romsdal region. This paper presents the development of a novel ROV for aquaculture inspection in marine application to provide first-hand information in fishery nets. The ROV is a part of so ...
In this paper we present a proof-of-concept for an hydro acoustic fish-tag position estimation and tracking system. In our field-tested concept, a formation of Unmanned Surface Vehicles (USV) creates a mobile array of low-cost hydro acoustic fish-tag receivers. The array of receivers is able to estimate ...
This paper presents a study of numerical models used in Real-Time Hybrid Model (ReaTHM) testing, conducted in a still water basin at SINTEF Ocean. ReaTHM testing is a method where a system is divided into physical and numerical substructures to study complex hydrodynamics on the physical system. Basin ...
This paper examines actual data for recent trends in electric energy demand in North America. Despite the conception of many persons, the electrical demand, as measured as either annual electric energy use or annual peak demand, is not rising rapidly. The reasons for this failure to grow are discussed, ...
This study used a regression method to build model for predicting water quality for the fish pond. From aquaculture practitioners' point of view, how to effectively control the water quality for the fish pond is very important. In basis of the experience of aquaculture practitioners, temperature, pH, ...
Since 21st Century, wind energy has become the world's fastest growing energy due to its characteristics of safety, cleanness and abundance as the demand for energy has doubled. This paper firstly explicitly introduces the distribution of China's wind energy resources and the features of wind resources ...
Electrical power plants with dieselgenerator sets segregated (i.e., the diesel generator sets are divided into different power buses and physical stations on ships and rigs) on several power buses have become the preferred solution for ships with various operational profiles and corresponding power ...
Landsat satellite images are extensively used in land-use studies due to their relatively high spatial resolution. However, the number of usable data sets is limited by the relatively long revisit interval and phenology effects can significantly reduce classification accuracy. Moderate Resolution Imaging ...
La pesca è uno dei settori più pericolosi in cui il numero di incidenti si verifica con elevata probabilità. I tempi di risposta per i soccorsi in mare sono spesso peggiorati dall'accessibilità della barca, così come dall'isolamento in cui si trova. La conoscenza del comportamento dell'intero sistema ...
Some Marine Spatial Planning (MSP) case studies have been investigated in order to evidence the importance of highresolution Synthetic Aperture Radar(SAR) wind data in semi-enclosed coastal seas. The MSP technique consisted in the optimum location of mussel aquaculture farms, on the basis of a Sustainability ...
Rabies is a globally distributed virus that causes approximately 60,00 human deaths annually with >99% of cases caused by dog bites. Australia is currently canine rabies free. However, the recent eastward spread of rabies in the Indonesian archipelago has increased the probability of rabies entry ...
We study the waves and wave-making forces acting on ships travelling on currents which vary as a function of depth. Our concern is realism; we consider a real current profile from the Columbia River, and model ships with dimensions and Froude numbers typical of three classes of vessels operating in ...
Vessel Monitoring System (VMS) data provide information about speed and position of fishing vessels. This opens the door to methods of estimating and mapping fishing effort with a high level of detail. To addess this task, we propose a new method belonging to the class of hidden Markov models (HMM) ...
ABSTRACT Anamorphic ascomycetes have been implicated as causative agents of diseases in tissues and skeletons of hard corals, in tissues of soft corals (sea fans) and in tissues and shells of molluscs. Opportunist marine fungal pathogens, such as Aspergillus sydowii, are important components of marine ...
