The present work explores the use of a numerical model to predict the barotropic tide along the West-Iberian region, extending from the Gulf of Cadiz to the Bay of Biscay and from the shelf to nearby seamounts (Gorringe and Galicia banks). The model is used, in a single isopycnal layer, to simulate the 2D propagation of the following eight principal tidal constituents: M2, S2, N2, K2, K1, O1, P1 and Q1. Astronomical tide-raising force is introduced into the equations of motion in order to improve model results. Recently updated global tide solutions are optimally combined to force a polychromatic tidal spectrum at the open boundaries. New bathymetry is built from hydrographic databases and used to increase the accuracy of the model, especially over the Portuguese continental shelf. Data from several tide gauges and acoustic Doppler current profilers are used to validate the numerical solution. Tidal amplitude and tidal current velocity solutions are evaluated by classical harmonic analysis of in situ and simulated time-series. Model outputs demonstrate the improvement of the regional hydrodynamic tide solution from earlier references. The harmonic solutions highlight small-scale variability over the shelf, and over nearby seamounts, due to the generation of diurnal continental shelf waves and topographic modulation of the semi-diurnal tidal ellipses. The barotropic forcing term is calculated over the study region and the main internal tide generation "hotspots" are revealed. © 2011 Elsevier B.V. Source

The Co-ReSyF project will implement a dedicated data access and processing infrastructure, with automated tools, methods and standards to support research applications using Earth Observation (EO) data for monitoring of Coastal Waters, leveraging on the components deployed SenSyF. The main objective is to facilitate the access to Earth Observation data and pre-processing tools to the research community, towards the future provision of future Coastal Waters services based on EO data. Through Co-ReSyFs collaborative front end, even young and/or inexperienced researchers in EO will be able to upload their applications to the system to compose and configure processing chains for easy deployment on the cloud infrastructure. They will be able to accelerate the development of high-performing applications taking full advantage of the scalability of resources available in the cloud framework. The included facilities and tools, optimized for distributed processing, include EO data access catalogue, discovery and retrieval tools, as well as a number of pre-processing and toolboxes for manipulating EO data. Advanced users will also be able to go further and take full control of the processing chains and algorithms by having access to the cloud back-end and to further optimize their applications for fast deployment for big data access and processing. The Co-ReSyF capabilities will be supported and initially demonstrated by a series of early adopters that will develop new research applications on the coastal domain, will guide the definition of requirements and serve as system beta testers. A competitive call will be issued within the project to further demonstrate and promote the usage of the Co-ReSyF release. These pioneering researchers in will be given access not only to the platform itself, but also to extensive training material on the system and also on Coastal Waters research themes, as well as to the projects events, including the Summer School and Final Workshop.

AW Energy Oys WaveRoller is the original concept to tame the surge in the nearshore areas. Although the major wave energy potential is clearly offshore in larger depths, apparently there still exist major drawbacks for the commercial-scale deployment of offshore devices, due to the necessity to rely on offshore maritime technologies, which on one hand are rather expensive and on the other hand are yet to prove their suitability for wave energy applications. For this reason, it shall be worth while to assess the value of on- and near-shore devices in particular in the present development phase: it is possible to use lower-cost modular technology and the devices are also much easier to maintain due to the proximity to the shoreline. WaveRoller is a unique, proven and patented product design for near-shore bottom wave (surge) energy conversion, and it was the first solution of its type (invented 1993 by Finnish professional diver). The detailed engineering, construction, deployment and monitoring of the simple and robust near-shore wave energy concept WaveRoller north of the Portuguese coastal town Peniche is an important step towards the large-scale reality of submerged near-shore wave energy utilisation. In addition to of the robust component and structural design, easy manufacturability and assembly, extensive technical and environmental monitoring activities will assure the appropriate assessment of the demonstaration plant .

The overall objective of the SeaDataNet II project is to upgrade the present SeaDataNet infrastructure into an operationally robust and state-of-the-art Pan-European infrastructure for providing up-to-date and high quality access to ocean and marine metadata, data and data products originating from data acquisition activities by all engaged coastal states, by setting, adopting and promoting common data management standards and by realising technical and semantic interoperability with other relevant data management systems and initiatives on behalf of science, environmental management, policy making, and economy. SeaDataNet is undertaken by the National Oceanographic Data Centres (NODCs), and marine information services of major research institutes, from 31 coastal states bordering the European seas, and also includes Satellite Data Centres, expert modelling centres and the international organisations IOC, ICES and EU-JRC in its network. Its 40 data centres are highly skilled and have been actively engaged in data management for many years and have the essential capabilities and facilities for data quality control, long term stewardship, retrieval and distribution. SeaDataNet II will undertake activities to achieve data access and data products services that meet requirements of end-users and intermediate user communities, such as GMES Marine Core Services (e.g. MyOcean), establishing SeaDataNet as the core data management component of the EMODNet infrastructure and contributing on behalf of Europe to global portal initiatives, such as the IOC/IODE Ocean Data Portal (ODP), and GEOSS. Moreover it aims to achieve INSPIRE compliance and to contribute to the INSPIRE process for developing implementing rules for oceanography.

The coastal area is the most productive and dynamic environment of the world ocean with significant resources and services for mankind. JERICO-NEXT (33 organizations from 15 countries) emphasizes that the complexity of the coastal ocean cannot be well understood if interconnection between physics, biogeochemistry and biology is not guaranteed. Such an integration requires new technological developments allowing continuous monitoring of a larger set of parameters. In the continuity of JERICO(FP7), the objective of JERICO-NEXT consists in strengthening and enlarging a solid and transparent European network in providing operational services for the timely, continuous and sustainable delivery of high quality environmental data and information products related to marine environment in European coastal seas Other objectives are: Support European coastal research communities, enable free and open access to data, enhance the readiness of new observing platform networks by increasing the performance of sensors, showcase of the adequacy of the so-developed observing technologies and strategies, propose a medium-term roadmap for coastal observatories through a permanent dialogue with stakeholders. Innovation JERICO-NEXT is based of a set of technological and methodological innovations. One main innovation potential is to provide a simple access to a large set of validated crucial information to understand the global change in coastal areas. Although JERICO-NEXT already includes industrial partners, it will be open to other research institutes, laboratories and private companies which could become associated partners to the project. Added values of JERICO NEXT JERICO-RI shall send data and information in an operational mode to European data systems, with dedicated service access. One of the strengths of JERICO-NEXT lies in the fact that technological and methodological developments shall be deployed in natural environment.
