The SEATONOMY methodology is a systematic approach to make efficient the design, development and verification and validation of autonomous systems. The relationship between levels of autonomy (LOA) and availability of communication is an important factor for underwater drones. Underwater autonomous ...
One of the main issues for using autonomous underwater vehicles in fish pen inspections is the pose estimation of the vehicle with respect to the fishnets. In this paper, a novel X-junction detector (Fast-Cross) is proposed, which is able to detect fishnet knots and their topology in camera images. ...
A Malaysian state of Sabah is blessed with natural deep sea water (DSW). The presence of these DSW's offers a potential for OTEC power plant to be installed and operated using warm surface sea water (SSW) as a heat source and the cold DSW as a heat sink. In the operation, the power plant may need to ...
Rural areas in South Africa and Zambia face a number of similar issues in the domains of agriculture, connectivity, water, transport, health and education etc., which calls for potentially similar solutions to be directed towards solving these issues. The intention of this research is to investigate ...
Urban sprawl/urbanization has large impacts on the structure and function of terrestrial ecosystems. Net primary production (NPP) is an important indicator for estimating the earth’s ability to support life and aids the evaluation of sustainable development of the terrestrial ecosystem. In this study, ...
The Blue Economy, also referred to as the ocean or maritime economy, is a concept that simultaneously encourage social inclusion, environmental sustainability, strengthening of maritime ecosystems, transparent governance as well as economic growth and development. This developing world initiative is ...
In the last decade, the use of underwater systems of all kinds has seen a steady increase. In this publication, we advocate the use of such systems in a complementary, collective, and networked manner. Even though today's achievements of such systems look impressive, the level of autonomy and networking ...
The proposed low cost systems shows the results obtained in the implementation and testing in marine environment of a Innovative Monitoring Underwater Buoy Systems for Marine and Rivers installation with IR-Cam, Instrumental Telemetry and Acoustic Data Acquisition Capability (MUnBuS). This concerning ...
A few diatom species produce toxins that affect human and animal health. Among these, members of the Pseudo-nitzschia genus were the first diatoms unambiguously identified as producer of domoic acid, a neurotoxin affecting molluscan shell-fish, birds, marine mammals, and humans. Evidence exists indicating ...
The overall objective of this proposal is to build an advanced and original prototype specifically devoted to seafloor and water-column monitoring as starting Italian contribution to the further development of the EMSO Ligurian Sea node. In detail the aim of the observatory is to ensure realtime continuous ...
Multibeam Echosounder (MBES) is increasingly becoming suitable for marine habitat mapping and various classification methods, diversifying in terms of classification algorithms, automation and MBES involved data features, are requiring scientific attention. On the other hand, the improved quality and ...
The proposed project shows the results obtained in the implementation and testing in lacustrine and marine environment of a nautical remote controlled vehicle with surface navigation and innovative features Semi-Immersible (SI-USV). This vehicle is based on a pending patent belonging to Palermo University ...
The proposed project shows the results obtained in the implementation and testing in lacustrine and marine environment of an innovative laterals hydro floating tilting systems control for USV or remote/autonomous surface nautical vehicles. This vehicle is based on a pending patent belonging to Palermo ...
This paper describes the development of cost-efficient, innovative and interoperable ocean passive acoustics sensors systems deployable from multiple platforms in the European FP7 project NeXOS (Next generation Low-Cost Multifunctional Web Enabled Ocean Sensor Systems Empowering Marine, Maritime and ...
There is a rising concern about the environmental status of the seas of our planet. Such concern regards several kinds of anthropogenic activities and their impact on the marine ecosystems. Part of the adverse effects are recognised to be due to various forms of acoustic emissions generated by human ...
New alliances between public and private partners at local, national and international level are needed to unlock the potential for growth from the maritime economy, boost green and blue technology development, and turn the environmental challenges into opportunities for innovation and sustainable development. ...
Nutrient pollution is one of worldwide most diffused, expensive and challenging environmental issues. The monitoring of nutrients in coastal areas is a complex task, due to the fact that the available methods reaching the required sensitivity are based on optical wet chemistry measurements. In order ...
The Environmental Impact Assessment (EIA) is an environmental management instrument implemented worldwide. In the last years the development of Wave Energy Converter (WEC) influenced environmental research to quantify impacts on marine life. In this paper we present a case study of EIA: a real application ...
A robust, reliable, small, light and low consumption water collecting device, or Sampling System (SS), is a fundamental part of any physical chain and any functional process aiming at automatically monitor or measure chemical or biological water parameters in-situ. Autonomous aquatic vehicles (ASV and ...
The interest in off-shore multi-purpose platforms resides in the wide opportunities involved in it, for example considering the development of large marine infrastructure in the near future. An available off-shore site where testing marine energy converters (exploitation of wave, tidal and hydrokinetic ...
