Metal contamination in soil from tailings induces risks for the ecosystem and for humans. In this study, the concentrations and ecological risks of Cd, Cu, Pb, and Zn in soil contaminated by a tailing from Yangshuo (YS) lead and zinc (Pb–Zn) mine, which collapsed for more than 40 years, were determined ...
Population densities and freshwater resources are not evenly distributed worldwide. This has forced farmers to use wastewater for the irrigation of food crops. This practice presents both positive and negative effects with respect to agricultural use, as well as in the context of environmental contamination ...
We have previously shown that K-selection and microbial stability in the rearing water increases survival and growth of Atlantic cod (Gadus morhua) larvae, and that recirculating aquaculture systems (RAS) are compatible with this. Here, we have assessed how water treatment influenced the larval microbiota ...
The dissemination of antibiotic resistant bacteria from anthropogenic sources into the environment poses an emerging public health threat. Antibiotic resistance genes (ARGs) and gene-capturing systems such as integron-associated integrase genes (intI) play a key role in alterations of microbial communities ...
Cystic fibrosis (CF) is a chronic disease in which the bacterial colonization of the lung is linked to an excessive inflammatory response that leads to respiratory failure. The microbiology of CF is complex. Staphylococcus aureus is the first bacterium to colonize the lungs in 30% of pediatric CF patients, ...
ABSTRACT Artificial habitats for animals have high commercial and societal value. Microbial communities (microbiomes) in such habitats may play ecological roles similar to those in nature. However, this hypothesis remains largely untested. Georgia Aquarium's Ocean Voyager (OV) exhibit is a closed-system ...
Flounder is a promising model species for environmental monitoring of coastal regions. To assess the usefulness of liver transcriptome profiling, juvenile olive flounder Paralichthys olivaceus were exposed to two pollutants, bisphenol S (BPS) and benzo[a]pyrene (BaP), which have different chemical characteristics ...
This study investigates the optical properties of oceanic waters around Tongyeong, where the aquaculture farms are repeatedly damaged by red tide since 1995. Through the field data sets obtained from a cruise campaign, absorption by optically active water constituents was obtained to analyze the spatial ...
This paper adresses underwater localization for an AUV using SLAM and Forward Looking Sonar (FLS) data. The proposed method is Rao-Blackwellized Particle Filter (RBPF) with grid mapping. The original RBPF uses multiple suggested trajectories, where each of which has a occupancy grid map. Analogously, ...
In this paper, a new form of multi-function offshore platform is introduced, and the power generation of wind turbine in swing situation is studied. The motion response of the platform under the influence of wave is solved by using the AQWA module of Ansys. Considering the relative geometric relationship ...
In this paper, we construct an enteromorpha remote sensing dataset. We take the eight channels data, from Band 1 to Band 8, in Landset 8 as spectral features of the dataset and consider the features extracted by Local Binary Patterns algorithm(LBP) and Gray-level Co-occurrence Matrix algorithm (GLCM) ...
We have succeeded in the development of an aquaculture tuna counting system using a multi-transducer and pinger. This newly developed multi-transducer sonar system is based on counting the individual fish that have passed through “the sound curtain” consisting of 15 transducers (460 kHz). In addition, ...
Aquaculture provides abundant food that directly consumed by humans. However, aquaculture cultivation is mainly replies on manual management. In order to improve the production efficiency and reduce the labor costs, numbers of recently developed techniques are applied to promote the automation level ...
The observation of marine life by autonomous underwater vehicle and the marine life counting and measurement system are highly required for the fisheries resources management. In this research, we propose an automatic flounder, which is valuable as a food resource, length measurement system. The proposed ...
Oceans covering 72% of the planet, commands the seventh position among the top ten economies. With the land based resources depleting fast, harvesting of the world's ocean resources are in the uptrend. Increased and sustained utilization of the blue economic resources has the potential to shift the ...
The hardware and software of the DHC sensor intended for investigation of plankton in a habitat, determination of its characteristics, and classification aimed at monitoring of species diversity are presented. Data of field measurements in the Kara Sea using the DHC sensor are considered and analyze...
In this study, the newly developed lightweight light-buoys, combined with 7 nautical mile self-contained power lantern, are firstly introduced. To reduce the total weight, EPP(Expanded polypropylene) and aluminum are applied for the buoyant body and tower structure, respectively. The new self-contained ...
