Abstract The transport of pollutant is an important topic for self-purification capability and environment evaluation of ocean. Chemical oxygen demand (COD, determined by potassium permanganate) is selected as a key parameter to indicate the water pollution degree. This study employs field measurements ...
Abstract Red tides off the Japanese coast caused serious damages to aquaculture industries in every year (Honjo 1994). To reduce fisheries damage due to red tide, it is important to inform aquaculturist of red tides in short-term scale distribution. We developed a monitoring system which collects real-time ...
Abstract In this paper, results from comparisons of simulations and measured offshore data from a floating combined wind and wave energy conversion system are presented. The device is a downscaled prototype that consists of a floating platform equipped with ten wave energy absorbers and three wind ...
Abstract Naturally occurring shoals and near-shore reefs act as good wave attenuators. Artificial creations of such nature identical attenuators are called artificial reefs. They are being increasingly deployed since the past decade, as artificial reefs may be included under soft engineering approach ...
Abstract The aim of this paper is to study anchor handling vessel (AHV) thrust capacity during anchor deployment. The thrust utilisation plot, a concept widely used in the Dynamic Positioning (DP) system, is used to illustrate the positioning capability of an AHV. Bollard pull reduction due to heavy ...
Abstract This paper investigated the performance of sustainability of a conceptual offshore platform that integrated renewable energy utilization and microalgae bio-fuel production in East China Sea. Triple I light (III light), which is calculated based on ecological footprint, bio-capacity, cost and ...
Abstract Benten River has a floodgate for disaster prevention. We have investigated the effect of the water supply from Benten River due to the floodgate opening on the water qualities in Shido Bay. Average values of salinity, turbidity and chlorophyll a to the deep direction at the inner bay were ...
Abstract Aquaculture cage systems are affected by various external forces from the ocean environment. Movements and deformation of netting can damage its structure and rearing species. Biofouling on synthetic fiber nets is a major concern for marine aquaculture systems because, it increases the net ...
Abstract This paper describes online simultaneous underwater image gathering, utilizing stationary camera node and movable camera node. We consider applying them to investigate the conditions of marine ecosystem around coral leaf at Okinawa, Japan. The framework of our proposed underwater image gathering ...
Abstract Offshore cages are designed to avoid further negative environmental damage in the coastal area while enable sustainable aquaculture growth. However, little is known about the environmental impact from this culturing activity in China. The objective of this study is to simulate the environmental ...
Abstract Recent years, the single-point mooring cage system has received much more attention because of their eco-friendly characteristics. Numerical simulation is performed to analyze the hydrodynamic behavior of a self-submersible single-point mooring gravity cage in waves and current. The effect ...
Background The aim of this study was to investigate the prevalence and characterization of Listeria species and Listeria monocytogenes isolated from raw fish and open-air fish market environments. Eight hundred and sixty two samples including raw fish and fish market environments (samples from workers’ ...
In deep-sea hydrothermal environments, most invertebrates associate with dense populations of symbiotic microorganisms in order to obtain nutrition. The molecular interactions between deep-sea animals and environmental microbes, including their symbionts, have not yet been elucidated in detail. Hemagglutinins/lectins, ...
Background Ostreid herpesvirus-1 (OsHV-1) is the major bivalve pathogen associated with severe mortality events in a wide host range. In the early summer of 2012 and 2013, mass mortalities of blood clam (Scapharca broughtonii) broodstocks associated with a newly described variant of OsHV-1 (OsHV-1-SB) ...
Fish lice (Argulus spp.) are obligate ectoparasites, which contrary to most aquatic parasites, retain the ability to swim freely throughout the whole of their life. In fish farms, they can quickly increase in numbers and without effective control cause argulosis, which results in the reduced growth ...
Underwater applications of photogrammetric measurement techniques usually need to deal with multimedia photogrammetry aspects, which are characterized by the necessity of handling optical rays that are refracted at interfaces between optical media with different refractive indices according to Snell’s ...
Ecological systems are dynamic and policies to manage them need to respond to that variation. However, policy adjustments will sometimes be costly, which means that fine-tuning a policy to track variability in the environment very tightly will only sometimes be worthwhile. We use a classic fisheries ...
Xenoturbella is a strange marine worm that can be collected regularly only off the west coast of Sweden. Due to its simple morphology, which lacks a centralized nervous system, coelom, anus, or reproductive organs, its phylogenetic position has long remained obscure. Recent phylogenomic analyses suggest ...
Abstract Tropidacris Scudder, 1869 is a genus widely distributed throughout the Neotropical region where speciation was probably promoted by forest reduction during the glacial and interglacial periods. There are no cytogenetic studies of Tropidacris, and information allowing inference or confirmation ...
Urothelial carcinoma (UC) comprises a heterogeneous group of epithelial neoplasms with diverse biological behaviors and variable clinical outcomes. Distinguishing UC histological subtypes has become increasingly important because prognoses and therapy can dramatically differ among subtypes. In clinical ...
