Messor, a simple but efficient towed vehicle have been built to obtain high-resolution data on the physical environment, phytoplankton, zooplankton, nekton and fish through a variety of sensors allowing multiple data acquisition with a near identical resolution in time and space. A multitude of towing ...
In recent years, all kinds of marine oil spill pollution events occur frequently. Marine oil pollution in the coastal ship oil spill accidents not only bring huge economic losses, but also directly destroy the marine ecological environment [5]. For sudden marine oil spill pollution events, simulating ...
A fuzzy rough set model was developed to assist in the fisheries management of bull shark nursery grounds located on the Texas & Louisiana Gulf of Mexico coastline. The results of the fuzzy rule-based model conform to the present plan but refine the environmental parameter ranges based on data accumulated ...
A new meta-heuristic algorithm, called Co-Operation of Biology Related Algorithms (COBRA), for solving real-parameter optimization problems is introduced and described. The algorithm is based on cooperation of biologically inspired algorithms such as Particle Swarm Optimization (PSO), Wolf Pack Search ...
This paper reports on a hydrophone based on a structure in which liquid was used to bridge the gap between a piezoresistive cantilever and the surrounding walls. Due to surface tension, the liquid filled the cantilever's gap while it did not leak through the microscale gap. Evaluation experiments showed ...
Social media is increasingly being used during crises. This makes it possible for crisis responders to collect and process crisis-related user generated content to allow for improved situational awareness. We describe a methodology for collecting a large number of relevant tweets and annotating them ...
The following topics are dealt with: power electronics; intelligent system; artificial neural network; electrical design; remote sensing; robotics; image processing; audio-video processing; and data mining.
At present, nanoparticles are beginning to influence our lives in many ways and understanding the environmental health and safety aspect of nanomaterials has become a crucial issue. The aim of the work was to assess and compare the acute toxicity of 31 different nanomaterials to fish mature individuals ...
CD79α (also known as Igα) is a component of the B cell antigen receptor complex and plays an important role in B cell signalling. The CD79α protein is present on the surface of B cells throughout their life cycle, and is absent on all other healthy cells, making it a highly reliable marker for B cells ...
Continuous marine environment monitoring is one of the main scientific topic for the oceanographic community involved in the analysis of climate changes and in the implementation of coupled ocean-atmosphere models. However, the space-time scale of the physical phenomena to be investigated, the need ...
Vessel Monitoring Systems (VMSs) are mainly meant to monitor and control fishing activity in ocean areas. VMSs have been realized and used in many ways, their principal aim being the monitoring, controlling and surveillance of fishing activity. The term VMS may refer to electronic or software systems ...
Synthetic Aperture Radar systems are powerful observation tools for maritime surveillance applications such as fisheries monitoring or pirates detection and oil slick detection. It is an important problem that has not been completely solved. In order to perform those detections, a search area is needed. ...
Acoustics resolve components of the ecosystem in time and space better than other methods. Additional sensors are needed to support the acoustic information with respect to identifications of specific targets and for including the biological information in the context of their physical environment. ...
The United States Integrated Ocean Observing System (IOOS®) is a user-driven, coordinated network of people, organizations, and technology that generate and disseminate continuous data about our coastal waters, Great Lakes, and oceans supported by strong research and development activities. IOOS® is ...
In Brazil, islands and areas surrounding the reservoirs of hydroelectric plants are often occupied by people that, if well managed, can be benefited from the economic activity related to the lake. Among these activities are: the agriculture, fishing industry, tourism, etc. As a result, a better organization ...
Prototype broadband split-beam echo sounder transceivers from Kongsberg Maritime have been used for about 3 years in a fishery research project. Linear chirp signals of different bandwidths and shapes have been transmitted and received on standard split-beam composite element transducers (nominal frequencies ...
The objective of the present study is to investigate the load effects due to sloshing impact on the fatigue assessment of an independent type B LNG tank. The selection of the cargo containment system type for an FLNG (Floating LNG) is mainly related to the sloshing problem. FLNG are considered to be ...
The high-risk nature of SCUBA diving activities is usually dealt with by pairing up divers and adopting well defined rules for diving operations to reduce the chance of accidents. However, during more challenging dives (such as technical dives) these procedures may not be sufficient to ensure almost ...
Age-structured demographic models were constructed based on empirical estimates of longevity and maturity for five deepwater Bering Sea skates to investigate how observed differences in life history parameters affect population growth rates. Monte Carlo simulations were used to incorporate parameter ...
Copper is essential for healthy cellular functioning, but this heavy metal quickly becomes toxic when supply exceeds demand. Marine sediments receive widespread and increasing levels of copper contamination from antifouling paints owing to the 2008 global ban of organotin-based products. The toxicity ...
