This year begins the so-called Decade of the Oceans, promoted by the United Nations with the slogan "The Science we need for the oceans we want". Based on the premise that global investment in marine science research is ...

Lagrangian Drifters are autonomous foating passive devices that provide oceanographic surface data. They are low-cost, low-power and easy-deployable marine instrumentation used in climate research. One of the main challenges ...

Estuaries are coastal indentations where freshwater mixes with seawater (Pritchard 1967), and are found everywhere in the world. Moreover, the estuarine ecosystems are usually characterized by high biological productivity ...

The development of new cabled oceanographic observatories is becoming of extreme importance to monitor in real-time a continuously changing environment. In this context, a local coastal network of fxed and mobile videomonitoring ...

All biological processes, from molecular to physiology and behavioural, are essential for organisms to regulate their survival in response to the environment (e.g., irradiance and temperature) and to intra- or inter- specifc ...

The global extent of macroalgae is declining with important consequences on marine biodiversity and ecosystem processes. Tracking the status and trends of macroalgal cover is, therefore, an emerging priority for ocean and ...

This communication describes a preliminary research on detection of big masses of plastic (marine litter) on the oceans and seas using EO (Earth Observation) satellite systems. Free images from the Sentinel 2 (Copernicus ...

The physical conditions of the Barents Sea, a note to fshing vessels. The conditions for fshing in the Barents Sea are excellent. An abundance of fsh and well-regulated agreements between Norway and the European Union ...

Monitoring plays a key role in all aspects of fsheries management, including those related to sustainable management of resources, the economic performance of the fshery, and the distribution of benefts from the exploitation ...

The monitoring of the environment is essential to know and study the diferent phenomena that occur in the natural environment. [1]. Atmospheric and oceanographic data sets share many characteristics. They can be very large; ...

A brief overview of Hercules Control’s ten years of existence as a marine technology developer. HCTech, with high impact developed products, is not able to bring them to the market. The people involved (research professor ...

Traditional drifting buoys have been designed to measure the surface currents at a nominal depth of 15m with drogues of 6m height. Herein, in order to assess the performance of HF Radars two designs of Lagrangian drifting ...

The Spanish Institute of Oceanography is responsible, among other aspects, for scientifc and technical advice for the Government’s fsheries policy as well as for the protection and sustainability of the marine environment. ...

The European Multidisciplinary Seafoor and water Column Observatory (EMSO, www.emso.eu) is a distributed research infrastructure (RI), composed of fxed-point deep-sea observatories and shallow water test sites at strategic ...

Human activities afects each environment, even the most remote, and the acoustic impact that these activities generate on the marine environment is not an exception. The Silencio project aims to developed innovative and ...

High-Frequency Non-Invasive (HFNI) instruments are currently used in bivalve mollusks in order to use them as bioindicators of the local conditions of the environment. Under the STRAUSS project an Arduino controlled equipment ...

Monitoring water transparency provides an indicator of the environmental status of the water body. One parameter to estimate the water transparency is the light difuse attenuation coefcient (Kd). In the framework of the ...

The identifcation of toxic microalgae is essential for the sustainable management of activities, such as aquaculture, being also relevant for environmental monitoring and marine research purposes [1]. For these reasons, ...

Here we present the development of a short range (0.5 to 20 m), low cost (< USD 5,000), three-beam, 1 MHz acoustic Doppler current profler called the Nortek ECO. The system employs a robust wideband velocity measurement ...

A fundamental component of the EMSO ERIC cyber-infrastructure that integrates multiple ocean variables from EMSO ERIC regional facilities is its data management platform. The EMSO data management platform transition to ...

The corrosion of steel due to seawater is a problem faced by all ships. In this work it has been analyzed two of the variables that most infuence the degradation process of carbon steels in marine environments (pH and ...

The development of straightforward tools in data analysis plays a signifcant role in the available accumulative data from marine observatories. A large number of diferent variables recorded with diferent formats in marine ...

The VENOM project has developed an unprecedented ultra-dense low-cost, and yet reliable, tide gauge network around the Balearic Islands to understand the very nature of the spatial variability of coastal sea level at ...

A portable module has been used to measure inorganic nutrients on the NW coast of the Iberian Peninsula during summer of 2019. The results allow us to know the variability of nutrient concentration and study the potential ...

The Guadalquivir River is dominated by the tidal fows coming from the Gulf of Cadiz, being the semidiurnal oscillation the most relevant in the area. Tidal constituents in the estuary are especially sensitive to variations ...
