Performing reliable underwater localization and maneuvering of Remotely Operated underwater Vehicles (ROVs) and Autonomous Underwater Vehicles (AUVs) near nature protection areas, historical sites or other man-made structures is a difficult task. Traditionally, different sensing techniques are exploited ...
There is significant evidence that the low-frequency mean acoustic noise pressure level in the ocean has been constantly increasing in the last decades. The main noise sources responsible for this increase were identified as ship traffic, offshore construction and oil & gas surveying. The Portuguese ...
Abstract Adaptation to ecologically contrasting niches can lead to the formation of new species. Theoretically, this process of ecological speciation can be driven by pleiotropic “magic traits” that genetically link natural and sexual selection. To qualify as a true magic trait, the pleiotropic function ...
In order to further expand the sustainability of maritime operations the use of autonomous vehicles has been employed at an increasing scale. This natural increase comes not only in the form of the multiplication of the numbers of the same vehicle model, but also in diversifying the vehicle composition ...
This article describes the developing capabilities of the wave-propelled AutoNaut unmanned surface vessel (USV) in surveillance roles, and the cost-effective part USVs can play in the evolving challenge of policing marine areas.
The use of serious games in health care interventions sector has grown rapidly in the last years, however, there is still a gap in the understanding on how these types of interventions are used for the management of the Parkinson Disease (PD), in particular. Targeting intelligent early detection and ...
Over the last three decades, video games have evolved from a pastime into a force of change that is transforming the way people perceive, learn about, and interact with the world around them. Despite this increased interest, a significant number of people encounter barriers when playing games, due to ...
Incidental capture, or ‘bycatch’ in fishing gear is a major global threat to sea turtle populations. A recent study showed that underwater entrapment in fishing gear followed by rapid decompression may cause gas bubble formation within the blood stream (embolism) and tissues leading to organ injury, ...
As the need for a sustainable presence in maritime operations rises so does the application of teams of autonomous vehicles as a means to meet this challenge. Although these teams present a unique opportunity to explore more complex concepts of operation, as well as more complex scenarios, they invariably ...
The Arctic region is one of the most sensitive and vulnerable to climate change. The dramatic melting of Arctic ice has several negative consequences for the whole ecosystem as well as for a way of life of native people but it also creates new opportunities for the region. First, it opens up potential ...
This paper describes a new methodology to analyze the effect of a marine outfall and its toxic waste on the surrounding submarine ecosystems, combining divers and a lightweight Autonomous Underwater Vehicle (AUV) deployed and controlled from a small recreational boat. The innovation here is twofold: ...
Data in the maritime domain is growing at an unprecedented rate, e.g., terabytes of oceanographic data are collected every month, and petabytes of data are already publicly available. Big data from heterogeneous sources such as sensors, buoys, vessels, and satellites could potentially fuel a large number ...
In support of ecosystem and fisheries studies the CSIRO has deployed a variety of towed and tethered systems to collect quantitative data to understand the distribution and makeup of mid-water biota. A series of platforms have been developed at the CSIRO which incorporate both imaging and acoustics ...
Great significance of underwater environment was gradually attracting attention and many traditional methods showed obvious shortcomings in underwater exploration, while the ground penetrating radar (GPR), as a new method in this field, performed well in identifying suspended solid and underwater relic. ...
Maritime areas covers a large percentage of our world, being most of this area unexplored. Despite this, the sea has one of the most valuable and mostly exploited “economic platforms” of mankind, with applications in different sectors (as fishing industry, transportation cargo, etc.). Although this ...
Unauthorized and uncertified small seagoing fishing crafts are being widely used for illegal, unreported and unregulated fishing, especially in the Indian sub-continent. Nevertheless, the registration is mandatory; the display of the registration mark and its standards for the seagoing fishing craft ...
Many changes are occurring in the physical, chemistry and biology processes of the ocean. Understanding how these changes are driven is an element of the key environmental descriptors identified by the European Marine Strategy Framework Directive (MSFD) with the ultimate goal being to protect the resource ...
Marine biodiversity is increasingly affected by human activities such as climate change, habitat destruction and fishing. In this context a key challenge for marine biologists is to be able to monitor biodiversity at large scale and high temporal frequency. However, underwater observations of marine ...
Dumped chemical weapons that are corroding and exposed to the marine environment can cause contamination and health risks for marine fauna and humans. This paper describes some of the work that is done in the EU-DAIMON (Decision Aid for Marine Munitions) project including the development of a decision ...
This article describes the initial planning and outcomes of validation and demonstration efforts for oceanographic sensors in the EU-funded project NeXOS. The project has developed novel, multi-functional optical and acoustic sensors for environmental monitoring and mapping. These sensors are subject ...
