Prediction of acoustic connectivity is the key to successful deployment of underwater acoustic communication systems, and in particular to deployment of multi-node networks. The connectivity is given mainly by the local sound propagation characteristics, which in turn are given by the spatial and temporal ...
The sustained and cost-effective monitoring of the water quality within European coastal areas is of growing importance in view of the upcoming European marine and maritime directives, i.e. the increased industrial use of the marine environment. Such monitoring needs mechanisms/systems to detect the ...
AUVs are self-propelled and able to navigate at an acceptable speed, but they need an electric motor and batteries that are limited in autonomy. Multivehicle fleet deployment can provide an adequate platform for conducting long term surveillance. Unexpected event detection can be more easily conducted ...
This paper will show how AUV and ROV can complement each other in a scientific mapping campaign in the Trondheim Fjord. To complete this survey, a multidisciplinary approach was necessary to adapt the industrial and military technology to identify and map object of interest (OOI) on the seafloor. NTNU ...
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 ...
The evolution of wetland of Nansi Lake was analyzed according to SPOT remote sensing data and its ecological environmental response was futher discussed with the wetland resource survey results, including benthonic animals, fish, and aquatic plants. It was characterized the reclamation in Nansi Lake ...
Based on the statistical data of 126 counties in Henan province, we described the spatial pattern and driving mechanism of per capita grain possession of Henan since the 1990s through the related analysis of spatial autocorrelation analysis, gravity center model and spatial econometric model. The results ...
With climate change programs such as REDD+, the ability to estimate biomass and carbon stock in juvenile plantings would be of high importance for auditing the contribution of the reforestation project by the relevant stakeholders. The ability of high spectral resolution imaging spectrometers to detect ...
Background Aquaculture is one amongst the growing and major food producing sectors. Shrimp culture is one of the subsectors of aquaculture that attracts more attention because of the economic interest. However, the shrimp culture systems have been facing severe consequences and economical losses due ...
Background & Objectives This paper describes chemical composition and antimicrobial activity of Cymbopogon nardus citronella essential oil against Edwardsiella spp. (n = 21), Vibrio spp. (n = 6), Aeromonas spp. (n = 2), Escherichia coli (n = 2), Salmonella spp. (n = 2), Flavobacterium spp. (n = 1), ...
Cichlid fishes constitute one of the most species-rich families of vertebrates. In addition to complex social behaviour and morphological versatility, they are characterised by extensive diversity in colouration, both within and between species. Here, we review the cellular and molecular mechanisms ...
The matching relationship between ship form, fishing nets and mean catch per haul of trawlers was investigated. According to the connection of these parameters, Index-weight method is used to formulated an optimization model of ship forms of trawler by taking the ship length, molded breadth and depth, ...
Malaysian fishing regulation prohibits any fishing activities using gill net since it frequently caused turtles captured in the net. In Malaysia only, the number of turtle landings has been decreasing every year while regulation enforced to prevent turtle extinction had affected fisheries production. ...
Underwater acoustics have been used for decades to observe and enumerate fish and other marine taxa. As early as 1935 the technique was used to observe fish vertical distribution, and techniques to quantify fish abundance followed. Today, these techniques are widely used to inform fisheries management. ...
An automatic method to compute resources estimation for coastal fishery was proposed by applying Information and Communication Technology (ICT) using real-time fishery information. The real-time fishery information used in the study is the location data of fishing vessels and the record of a catch in ...
Recent advances in information and communication technologies are leading to an environment where marine traffic (i.e., locate and track vessels) can be monitored in real time. For larger vessels, position information is collected by sniffing messages of AIS (Automatic Identification System), which ...
To date, the authors of this report have carried out estimations of initial stock size and catch per unit effort (CPUE) calculations in real time by collecting positional information and catch information from small fishing vessels using a sensor network system, and have facilitated fisherman-driven ...
Digital Ocean is of great strategic significance for the development of the country, its powerful data acquisition ability and spatial analysis ability to provide support and security to safeguard the national marine rights and interests, the reasonable exploitation of marine resources. Current situation ...
The development of cost-effective management strategies, including mapping of the submerged cultural heritage - potentially extensive even at quite great depths - is becoming ever more important, given increasing commercial activity in marine areas which may cause damage or prevent further investigation ...
Background We have developed a new paradigm that targets the recognition of facial expression of emotions. Here we report the protocol of a randomised controlled trial of the effects of emotion recognition training on mood in a sample of individuals with depressive symptoms over a 6-week follow-up ...
