The equipment represents the achievement of a joint work from different scientific and technological disciplines as electronics, mechanics, acoustics, communications, information technology, marine geophysics, etc. This easy to handle and sophisticated equipment allows to record useful active and passive seismicity information, as well as other

Cabled observatory video monitoring allows such a sampling at a high frequency. Unfortunately, automated animal visual counting is still a major bottleneck. We developed a new automated video-imaging protocol for the 24-h continuous counting of fishes in calorimetrically calibrated time-lapse photographic outputs, taken by a shallow water (20 m depth) cabled video-platform, the OBSEA. All the images were acquired within a standardized Region Of Interest, represented by a 2 x 2 m methacrylate panel, endowed with a 9-colour calibration chart, and calibrated using the recently implemented “3D Thin-Plate Spline” warping approach.

In the past two decades, as interest in exploring the oceans for valuable resources and in protecting these resources from overexploitation have grown, the number of cabled (permanent) submarine multiparametric platforms with video stations has increased. Prior to the development of seafloor observatories, the majority of autonomous stations were battery powered and stored data locally. The recently installed low-cost, multiparametric, expandable, cabled coastal Seafloor Observatory (OBSEA), located 4 km off of Vilanova i la Gertrú, Barcelona, at a depth of 20 m, is directly connected to a ground station by a telecommunication cable; thus, it is not affected by the limitations associated with previous

This has direct implications on ocean observing systems, including scientific planning and technology. For instance better knowledge implies that data on health, climate and overall dynamics of our oceans have a known level of quality, be up-to-date, be easily discoverable, be easily searchable both in time and space, and be human-and machine-readable in order to generate faster decisions when and where needed. Requirements with respect to spatial regions and scales (seas and ocean basins, from millimeters to hundreds of kilometers), time scope and scales (past, present, future, from microseconds to decades) indeed have direct implications on observing systems' spatio-temporal sampling capabilities. Possibly high spatial and temporal resolution also means unprecedented amounts of data, communication bandwidth and processing power needs. Technological implications are thus quite substantial and in this short article we will try to provide a review of some initiatives of global and local focus that are aiming to respond to at least some of these needs, starting with the application of the Global Earth Observation System of Systems (GEOSS) guidelines to ocean observatories. Then we will address real scenarios in real ocean observing facilities, first with the European Seas Observatory Network and the European Multidisciplinary Seafloor Observation(ESONET-EMSO), then two recently associated Spanish initiatives, the Oceanic Platform of the Canary Islands (PLOCAN) infrastructure and deep sea observatory in the Canary Islands, and the Expandable Seafloor Observatory (OBSEA) shallow water Western-Mediterranean observatory of the Technical University of Catalonia, one of the first real-time ocean observatories implemented with state-of-the-art interoperable concepts, down to the sensor interface.

La buena acogida que tuvo esta iniciativa nos ha animado a continuar la experiencia y durante este curso 2002-2003 se ha desarrollado el segundo trabajo conjunto de investigación, titulado ‘Meteorología y clima en la comarca del Garraf’. El objetivo del proyecto ha sido formar un grupo de trabajo interdisciplinario, tutorizado por la EUPVG, con estudiantes de los diferentes centros de secundaria que están cursando las modalidades de bachillerato tecnológico, científico y social. La elaboración de los trabajos ha hecho posible un acercamiento de estos estudiantes que estan finalizando el bachillerato al mundo universitario. Al mismo tiempo ha permitido la utilización por parte de éstos de ...

Theses power cables are exposed to the dynamic behaviour of the platform movements due to waves, currents and wind. Preliminary simulations of the static and dynamic behaviour of a power cable moored at small depth are done. The study is focused on a static study of cables about 0.1 m diameter in a catenary mooring under different seabed conditions, bending stiffness and cable length. A preliminary dynamic study is also done: the trajectory, tensions and deformation or curvature of such a power cable under a specific periodic wave conditions characteristics of catalan coast, in Mediterraneum, are shown. The static study gives useful information to be used when a dynamic mooring is build. The simulations are done under OrcaFlex software (license N1594).

It consists of different controllers which handle different RFID antennas. The controllers send the data received from its antennas to a host computer that computes the tracking of the different individuals. The system has a tracking resolution of centimetres and was specifically designed to respond in hostile environments and to allow an easy configuration and expansion.

They are also used to detect tsunamis and generate warning alarms. This paper presents a data acquisition system built for an OBS with capability to synchronize time through IEEE-1588 protocol. This acquisition system provides real time data through the Ethernet making it suitable for OBSs deployed at seafloor observatories. Peer Reviewed Postprint (published version)

This was the rst underwater research project using autonomous underwater vehicles in Spain. One of the participants was the SARTI group, with the AUV “Guanay II”. This paper presents the salinity results obtained with Guanay II, and the operational methodology followed to achieve these results.

In fact, CORBA, Java and RMI include base technologies, the mobile agents make the distributed calculation for the local real time processing easy and the configurable processes without prerequisite and Web Services provides a distributed, open and secure architecture. Web Services is a software environment in which the services are provided by URI identified applications, whose interfaces and methods are explained using XML. The users are capable of finding them and learn how to use them. With this new architecture, we achieve a totally distributed system since users can be distributed in a intranet or in internet, the applications can be distributed and they can be found thanks to the UDDI and LDAP services, the process can be distributed using Java Beans and RMI, data are distributed using RMI and all that in a secure environment thanks to SOAP and HTTPS (
