This paper introduces the Smart Electronic Interface for Web Enabled Ocean Sensor Systems of the NeXOS project as example how interoperable standards help, to facilitate the creation of an infrastructure for sharing oceanographic observation data and the integration of sensor into marine installations. A given kind of sensor may be deployed on various platforms such as floats, gliders or moorings,...
To educate undergraduate and graduate students in the fundamentals of robotics focused engineering science, it is necessary to provide hands-on laboratory experiences that illuminate the theories and show their practical applications. Through a program of courses and real world applications it is possible to extend a students knowledge and expertise in areas of relevance and get students on the cutting...
Underwater sensors of water flow share issues addressed independently by manufacturers. Power has become the most demanding concern since availability of cheap memory has removed data storage as the limit for self-contained current meters. Neither power nor memory is a limit with cabled observatory instruments but for autonomous installations, improvement in batteries is valuable but not sufficient...
This paper describes the motivations and main components of MEUST (Mediterranean Eurocentre for Underwater Sciences and Technologies), a permanent deep sea cabled observatory being deployed off shore of Toulon, France.
The Oceanographic Systems Laboratory at Woods Hole Oceanographic Institution has developed a low-power multi-frequency sonar board capable of operating at a wide range of frequencies from 200 KHz to 2 MHz and suitable for a wide range of applications. Its features include a transmitter, a receiver with gain control, a 24 MHz analog-to-digital converter, a programmable down converter capable of demodulating...
The growing use of robotics in the maritime domain is about to pose questions on legal fallouts of autonomous systems to the international community. Unmanned maritime systems (UMS) such as autonomous underwater vehicles (AUVs) and unmanned surface vehicles (USVs) are being increasingly employed for environmental and scientific studies. Applications of not weaponized robotic platforms for maritime...
The SN1 observatory is a cabled deep-sea observatory operating in real-time since 2005 in Southern Italy (East Sicily), at 2100 m water depth, 25 km from the harbor of the city of Catania. A structural enhancement of the SN1 observatory is undergoing in the framework of the Italian EMSO MedIT project, including the implementation of a multi-parametric monitoring system for observation in the water...
The paper gives a brief account of the essential steps integrated and relevant to ocean observation systems, namely: a). development of a series of new sensors and measurement techniques, b). commercialization of the technology, c). implementation of the technology in more than 100 institutions, d). training to the end users and finally e). raising the technology as important part to the syllabus...
The hovering type AUV Tri-TON 2 was developed by the Institute of Industrial Science, The University of Tokyo in 2013. The AUV was constructed as a test bed for a national project to develop instruments to estimate ore reserves in underwater hydrothermal deposits. In order to estimate its position and orientation in real time, the AUV uses a SBL-based acoustic localization device instead of a conventional...
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 (Patent Pending RM2012A000209 and RM2012A000209) concerning innovative semi-immersible vehicles...
It is known that there are mineral deposits below seafloor. Gravity survey is one of powerful methods for exploration of underground deposits. A new system is needed to survey a wide area quickly with a higher resolution. Recent technology of an autonomous underwater vehicle (AUV) enables us to measure gravity in underwater environment. We have developed an underwater gravity measurement system for...
The Deep Gen project aims at defining a generator that powers the typical mooring of instruments used for data acquisition purpose in both the deep and the shallow water environment. The generator itself is named Deep Gen. The Deep Gen exploits the marine currents to produce electrical power. Thus, instead of using only a fixed energy storage (batteries) to power the underwater instruments, here the...
The high-quality backscattered spectra provided by the WERA HF radar systems in the Wave Hub area are used to estimate different wave parameters at the location of a wave buoy. The HF radar estimations are done using three different wave estimation algorithms: the standard WERA software, the software provided by Actimar and the software provided by Seaview Sensing. The data obtained with each methodology...
The currents measured by a SonTek Acoustic Doppler Current Profiler (ADCP) mounted on an Iver2 Autonomous Underwater Vehicle (AUV) are compared to those measured by a bottom-mounted Acoustic Wave and Current Meter (AWAC), taken as a reference, in an attempt to evaluate the AUV's performance as a current meter instrument. In October 2013, the AUV performed 3 short missions navigating over the AWAC...
Marine survey provides many kinds of oceanic samples and large volume of corresponding data, which are treasurable materials for further scientific researches, and should be shared among scientists, agents or organizations from different areas. In this paper, we contribute to the design of a domain-specific provenance model based on the PROV-DM model for Marine survey project. We start from an analysis...
The process of ocean turbulence mixing generally exists in the ocean. Time series of turbulent fluxes for several months' duration can serve to understand the role of ocean mixing. In view of this, the Mooring Turbulence Measuring Instrument (MTMI) developed by Ocean University of China (OUC) had been deployed in the South China Sea for about 110 days to obtain long duration data. In this experiment,...
The GUARD1 system is a low-cost stand-alone instrument for underwater image acquisition and recognition of gelatinous zooplankton. It is designed for installation and autonomous operation on different platforms (e.g. fixed, towed, mobile). Its low cost, small size and low power consumption coupled with a long-life battery pack equipment, make it an ideal system for long lasting deployments. The system...
The design of an existing in-house scientific instrument was used as a basis to create a new model suitable for deployment onto a fishing industry vessel, with a reduced need for specialized technical support. Some of the planned developmental goals were met directly, whilst others resulted in intermediate problems that required remedial action in order to deliver the desired outcome. The developmental...
