Recognizing a submerged body in turbid water is extremely challenging despite the clear necessity from a diver or a submersible. Above all, the water turbidity and limited light condition prohibit clean image quality. Even with a visible image, the conventional feature-based approaches would be limited ...
Autonomous underwater navigation presents a whole set of challenges to be resolved in order to become adequately accurate and reliable. That is particularly critical when human divers work in close collaboration with autonomous underwater vehicles (AUVs). In absence of global positioning signals underwater, ...
Competitive diving is a well recognized aquatic sport in which a person dives from a platform or a springboard into the water. Based on the acrobatics performed during the dive, diving is classified into a finite set of action classes which are standardized by FINA. In this work, we propose an attention ...
Background: Health disparities related to environmental exposure exist in different industries. Cancer is currently a leading cause of morbidity and mortality worldwide. Much remains unknown about the types of work and industries that face the greatest cancer risks. In this study, we aimed to provide ...
Population movement is a major driver for infectious disease transmission and can impact the success of disease control and elimination strategies. The relationship between disease transmission and permanent migration is well documented, but fewer studies have considered how different types of population ...
The Automatic Identification System (AIS) is widely used by mariners at sea as a compulsory collision prevention device on-board. Since the inception of collaborative platforms that gather AIS messages received by a network of stations, large worldwide AIS datasets can be assembled and enable a series ...
Vessel Monitoring Systems (VMS) offer trajectory data of fishing vessels to excavate spatio-temporal pattern of fishing activity and impact on resources. This paper proposes a spatio-temporal fine-grained density prediction model of fishing vessels, called ST-FiD. This model finds a data structure to ...
DARPA's Ocean of Things (OoT) program enables persistent maritime situational awareness over large ocean areas by deploying thousands of low-cost, intelligent floats that drift as a distributed sensor network. Each float manages a suite of commercially available sensors to collect environmental data ...
Several techniques have been studied, invented and reformulated to enhance automatic ships detection using SAR images. Depending on how the information is gathered and processed each technique presents different performances and results. Nowadays there are several missions on going, and the need to ...
The authors propose to improve litter and plastic pollution tracking in the Ocean through a combined solution that includes tracking from space and a drift modelling service based on surface currents derived from Earth Observations satellites. Tracking litter-like transmitters at sea helps in improving ...
Biofouling on deployed in-situ sensors without regular removal or cleaning can disrupt sensor data collected. The current replacement antifouling (AF) materials under development are largely unsuited to sensor technologies as they have been developed with large scale applications in mind, such as those ...
An eight-element oil-filled hydrophone array is used to measure the acoustic field in littoral waters. This prototype array was deployed during an experiment between Jeffrey's Ledge and the Stellwagen Bank region off the coast of Rockport, Massachusetts USA. During the experiment, several humpback whale ...
The overall aim of the GLIDER project is to demonstrate an innovative, flexible and cost-efficient offshore monitoring and data management approach. GLIDER consists in the deployment of 3 ocean autonomous and mobile platforms, a Sea glider (Kongsberg), a Sailbuoy (Offshore Sensing) and a Wave Glider ...
Global changes affect the entire planet at all scales, terrestrial and marine. The impact of anthropogenic pressures on marine ecosystems has been relatively little studied because of the lack of data and the difficulty to acquire it. Fine resolution cartographic data (1:10 000) of marine habitats on ...
Non-indigenous aquatic species (NIAS) are those that can be introduced outside of their natural range or dispersal potential through intentional or unintentional introduction resulting from human activities. NIAS may be brought into another country during shipping by becoming attached to the ship hull ...
Data assimilation (DA) and machine learning (ML) are empirically compared for automatic daily fish catch forecasting (DFCF). ML would be a promising approach if large-scale data are available for training. Otherwise, DA would perform well, where prior knowledge on a monitoring target is incorporated ...
In recent years, the study of organizational and employee happiness has become a prevalent and increasingly important research topic in the field of management science. At present, however, there are few studies that aim to examine the happiness of employees working in Industry 4.0 environments. Against ...
Fish processing industries involve the usage of energy-intensive equipment, such as refrigerators, air conditioners and ice making machines leading to high energy costs and, indirectly, to an increase of the carbon emissions. As most fish industries sites are old, there is a strong need to make them ...
As the marine industry moves towards the industry 4.0 era, the role of automated smart design is becoming increasingly significant. This offers an ability to produce highly customisable design and to integrate with the product-lifecycle process such as digitalised ship production and ship operations ...
The effective use and control of maritime routes in the commercial/military area is an increasing and important need for states. There are some motivations for this purpose: Safe traffic of the ships in narrow canals, avoiding illegal usage of anchoring areas of ships, monitoring fishing activities ...
