We'll want to implant the awareness of the importance at measurement's quality that must have with systems acquisition own design. The choice of system acquisition will be very important because this system will must fulfill ...

This paper describes the principle of operation of the fluxgate sensors. The effect of the magnetic hysteresis was specially taken into account. It was found that the hysteresis does not distort the linear characteristic ...

Several Low-Coast Drifting Buoys (LCDB) have been designed and constructed at ICMAN-CSIC to determine flow characteristics of The Guadalquivir Estuary. Position and velocity of the driftes can be sent to a local server ...

The OBSEA observatory, for its construction, characteristics and loation in the seafloor, needs a cabling and connections structure capable to satisfy its finality and to resist the adverse conditions of thes sea environment.

The aim of this paper is to present the design and construction process of the power supply needed for a remote data acquisition system. It is based on twuelvw AC to DC switching converters in a serial connection and a ...

TEMPO-Mini is a new custom-designed instrument package created by IFREMER for real-time monitoring of hydrothermal faunal assemblages.

The Canary Islands Oceanic Platform (PLOCAN) is a public infrastructure for research, development and innovation in the fields of ocean science and technology at increasing depths. Located East of Gran Canaria Island ...

During the past decades, Ocean Bottom Seismometers (OBS) have played a key role in permanent seismic activity monitoring at sea as well as allowing a better understating of the earth interior. Data collected by the ...

This work verifies and validates the calibration in a marine geophone by means of a hyperbaric chamber before and after the pressure underwater laboratory test. The objective is to characterise the transfer function ...

This paper proposes a pose-based algorithm to solve the full SLAM problem for an Autonomous Underwater Vehicle (AUV), navigating in an unknown and possibly unstructured environment. The technique incorporate probabilistic ...

This paper describes the design and construction of the pressure hull of Ictineu 3, a manned submersible with a maximum operative depth of 1200m. The design and manufacturing process of a pressure hull is a cumbersome ...

In this paper offers a comparative analysis and classification of mathematical models and the Saint-Venant ARMAX model, and determine which is more useful for the computation applied to control systems in the first section ...

This paper describes a new control surface actuating design for the Monterey Bay Aquarium Research Institute (MBARI) Dorado class AUVs. The intent was to increase reliability as part of obtaining the goal to greatly ...

The dredging is a process that intrinsically damages the aquatic environment. Suctioning part of the aquatic bottom surface suppose not only change the ecosystem but it endanger the life of the animal and plant species. ...

We will explain the first interpretations from a marine refraction and wide-angle reflection seismic profile acquired in the outer part of the Gulf of Cadiz in November 2008, in the framework of the Nearest-Seis cruise.

The study of active structures offshore requires very-high resolution seismic imaging in order to observe the most recent layers below sea floor. In the other hand, high penetration methods are necessary to observe deeper ...

Within the tasks devoted to operational oceanography, Coastal Ocean Observatory at Institut de Ciències del Mar (CSIC) has acquired an European Organisation for the Exploitation of Meteorological Satellites (EUMETSAT) ...

The TT-transform stands for time-time transform and has been derived as an inverse Fourier transform of the time-frequency S-transform. So far, it has been proposed that the diagonal of the TT-transform can be used for ...

A method for improve the reliability in a gas liquefied plant using Hotelling T2 is showed in this paper. The stationery work in this manufacture facilities during a few moths in a year involve a heavy duty service of ...

The length scale and the spatio-temporal variation of turbulence intensity has relevant implications on phytoplankton dynamics. Thus, it is important to estimate the relevant parameters that characterize the turbulence ...

The aim of this paper is to propose a method of source localization using a single hydrophone in shallow water. To perform this localization, modes are first filtered in the time-frequency plane and then used in two ...

We explored telemetry of transmitter tagged fishes from an autonomous underwater vehicle with a hydrophone/ datalogger processing code-division-multiple- access acoustic signals. Geolocation estimates used synthetic ...

Evaluation of phytoplankton communities is an important task to characterize marine environments. Fluorescence spectroscopy is a powerful technique usually used for this goal. This study presents a comparison between two ...

Since January 2008, The Guadalquivir Estuary has been equipped with a large amount of instrumentation performing an intensive collection of meteorological, hydrodynamic, hydrological and water-quality parameters. An ...

IEEE-1451[1] and OGC Sensor Web Enablement (OGC SWE)[2] define standard protocols to operate instruments, including methods to calibrate, configure, trigger data acquisition, and retrieve instrument data based on specified ...

In this work a Geographic Information System Architecture for Oceanographic Data is presented. This has been designed by the Unidad de Tecnología Marina to be used into an Oceanographic Data Acquisition System implemented on ...

In this paper will be presented an overview of the information treatment servers structure used in the OBSEA project explaining and justifying the chosen topology.

While noise is now considered a marine hazard that can directly affect cetaceans and induce a stranding, no clinical approach has yet introduced the detection of a possible hearing loss at a stranding site as a necessary ...

Hydrophone arrays permit to localize populations of cetaceans in realtime so as to study their behaviour in a non-invasive way and to work on their conservation. The most commonly used method based on time-difference-o ...

The control of noise interaction between artificial and biological sources is essential to assess the development of sustainable marine technologies. Therefore, there is an emergent need to conduct morphological analysis ...

The automated, real time classification of acoustic events in the marine environment is an important tool to study anthropogenic sound pollution, marine mammals and for mitigating human activities that are potentially ...
