Abstract This paper describes how Ocean Power Technologies (OPT) successfully transferred technology developed in the Renewables sector to Defence and is currently repeating this process for the Oil & Gas (O&G) market, providing solutions that could drive down project OPEX & CAPEX to help ...
Aromatase, the key enzyme responsible for estrogen biosynthesis, is present in the brain of all vertebrates. Much evidence has accumulated that aromatase is highly and exclusively expressed in proliferating mature radial glial cells in the brain of teleost fish even in adulthood, unlike in other vertebrates. ...
Marine fish and shellfish are primary sources of human exposure to mercury, a potentially toxic metal, and selenium, an essential element that may protect against mercury bioaccumulation and toxicity. Yet we lack a thorough understanding of Hg and Se patterns in common marine taxa, particularly those ...
Abstract The scale of current marine stakeholder activity in the North Sea is such that considerable effort is required to minimise the impact of operations conducted adjacent to one another. Impacts are typically spatial – vessels wanting to work in the same physical space at the same time, or acoustic ...
Marine invertebrates commonly have a biphasic life cycle in which the metamorphic transition from a pelagic larva to a benthic post-larva is mediated by the nitric oxide signalling pathway. Nitric oxide (NO) is synthesised by nitric oxide synthase (NOS), which is a client protein of the molecular chaperon ...
Abstract The learning from incidents and subsequent improvements made for the protection of people and integrity of offshore installations over the last 25 years has no doubt saved numerous lives. Places of refuge, blast protection, rapid isolation processes, offshore survival training and improved ...
Background Arrays of passive receivers are a widely used tool for tracking the movements of acoustically-tagged fish in marine ecosystems; however, the spatial and temporal heterogeneity of coral reef environments pose challenges for the interpretation of tag detection data. To improve this situation ...
The odorant partition coefficient is a physicochemical property that has been shown to dramatically influence odorant deposition patterns in the mammalian nose, leading to a chromatographic separation of odorants along the sensory epithelium. It is unknown whether a similar phenomenon occurs in fish. ...
In this paper we present an algorithm for visual object detection in a underwater real-life context which explicitly models both the background and the foreground for each frame - thus helping to avoid foreground absorption into similar background -, and integrates both colour and texture features (which ...
In this work a new concept of the system entrepreneurial approach to the organization of maritime engineering education in the Russian Federation is offered. The basis of this approach is the maritime entrepreneurial universities in the regions of Russia having access to the Atlantic, Arctic and Pacific ...
In this paper we have shown how to monitor the water level of water systems such as water tanks, rivers, ground water table, and bore wells remotely. We have also shown that how to control the working of pump automatically and remotely. It can also be used to remotely monitor the flood areas wirelessly ...
This study presents the effect of source-drain metal shield in FET structure on drain leakage current. The FET structure was fabricated on the wafer by using MIMOS's standard fabrication process. Aluminum (Al) was sputtered with thickness of 400 nm as metal shield layer at the source and drain area ...
We propose an approach for the analysis of fish trajectories in unconstrained underwater videos. Trajectories are classified into two classes: normal trajectories which contain the usual behavior of fish and abnormal trajectories which indicate the behaviors that are not as common as the normal class. ...
Environmental Microorganisms (EMs) are currently recognised using molecular biology (DNA, RNA) or morphological methods. The first ones are very time-consuming and expensive. The second ones require a very experienced laboratory operator. To overcome these problems, we introduce an automatic classification ...
According to The State of World Fisheries and Aquaculture 2012, a publication of the Food and Agriculture Organization of the United Nations, five Asian nations topped the world ranking of mariculture producers in 2010. In order, they were China, India, Vietnam, Indonesia, and Bangladesh. Asia's maricultural ...
Comprehensive ocean planning must account for the diversity of human uses that converge in coastal waters and their potential impacts on marine ecosystems. Ocean plans have been developed at the federal, regional, and state level to address these issues; however, the under-documentation of human activities ...
Oceanic intrusions of dense, hypoxic water regularly occur at the entrance to Puget Sound, WA (USA), and may be significant to regional dissolved oxygen levels. Seabed observations at Admiralty Inlet from 2009 to 2013 show a strong correlation of low dissolved oxygen concentrations with high salinity, ...
The energy and data hybrid transmission technology is one of the most important technologies in the field of submarine investigation and exploitation. It is urgent to study high-power and high-speed hybrid transmission technology. All kinds of submarine equipments, using electric motor to drive the ...
Mini-ROVs have been accepted as a mainstream tool and the demand for them has increased rapidly. This success may be attributed to excellent ease of use, the availability of advanced new capabilities and an attractive price/performance ratio.
Conference proceedings front matter may contain various advertisements, welcome messages, committee or program information, and other miscellaneous conference information. This may in some cases also include the cover art, table of contents, copyright statements, title-page or half title-pages, blank ...
