| In marine sciences, many fields display high variability over a large range of spatial and temporal scales, from seconds to thus ousands of years. The longer and longer recorded time series, with an increasing sampling frequency, in this field are often nonlinear, nonstationary, multiscale and noisy. Their analysis faces new challenges and thus requires the implementation of adequate and specific methods. The objective of this paper is to highlight time series analysis methods already applied in econometrics, signal processing, health,etc. to the environmental marine domain, assess advantages and inconvenients and compare classical techniques with more recent ones. Temperature, turbidity and salinity are important quantities for ecosystem studies. The... |

| The JERICO European research infrastructure (RI) is integrating several platform types i.e. fixed buoys, piles, moorings, drifters, Ferryboxes, gliders, HF radars, coastal cable observatories and the associated technologies dedicated to the observation and monitoring of the European coastal seas. The infrastructure is to serve both the implementation of European marine policies and the elucidation of key scientific questions through dedicated observation and monitoring plans. It includes observations of the physical, chemical and biological compartments and aims at a better integration of marine biology with physical and chemical oceanology, through specific interactions with other relevant ocean observing systems that provide complementary observations.... |

| Six Joined Research activity Projects (JRAPS have been achieved within JERICO-NEXT. These projects have been set up to tackle some of the complex technical and scientifical issues associated with the implementation of Coastal Ocean Observing over a wide range of environmental conditions and spatiotemporal scales. The topics of these projects have been defined in relation with some of the Marine Strategy Framework Directive: JRAP 1: Biodiversity of plankton, harmful algal blooms and eutrophication, JRAP 2: Monitoring changes in microbenthic biodiversity, assessing potential environmental controls and functional consequences JRAP 3: Occurrence of contaminants in Northern coastal waters and biological responses JRAP 4: 4D characterization of trans-boundary... |

| The Network of Excellence ESONET started on 1st March 2007. The kick off meeting was held in Brest on 21-22-23 March 2007. Long term monitoring of environmental processes related to ecosystem life and evolution, global changes and geohazards, is now recognized as a necessary by the scientific community. To better understand geophysical, biogeochemical, oceanographic and biological active phenomena scientists need long time series of data coming from the deep sea and the seafloor at key provinces in the world. The objective of ESONET NoE is to prepare at European level the implementation of a network of deep sea observatories around Europe. The structures of ESONET have been constructed during the first year through the main meetings (Kick off meeting... |

| The objectives of JERICO are to address the challenge of observing the complexity and high variability of coastal areas at Pan-european level, in the framework established by European Directives (WFD, MSFD) and the operational marine services (GMES) by: - setting up an European Research Infrastructure for coastal observations based on existing systems in European coastal and shelf seas. - supporting standardization of methodologies for the benefit of data quality, data availability and cost efficiency. - promoting the cost-effective use of the facilities. - stimulating the development of new automated systems for the operational monitoring of the coastal marine, environment, with focus on the biochemical, compartment. To reach these objectives the JERICO... |

| A synthesis of 9 years of hydrographic measurements, acquired during approximately 25 cruises (1992-2000) on the French continental shelf of the Bay of Biscay, is presented. The main focus is upon salinity distribution, as it is little known in this area. The whole of the data set covers I I months of the year, with some sampling fields repeated several times a year, for multiple years. This time-series allows temperature and salinity distributions to be studied together with their seasonal, inter-annual and mesoscale variability. The seasonal trend in temperature can be described in three stages, which are in agreement with past studies. Thermal stratification occurs between May and mid-September in a layer similar to 50 m in thickness, whereas the... |

| Time-series analysis is one of keys opening towards the future for marine sciences and industry to understand ocean processes and their dynamics. It not only helps identifying the phenomenon represented by sequences of observations, but also helps forecasting events by feeding models. Thanks to technological progress, marine scientists are benefiting from longer and longer data timeseries with higher acquisition frequency, but they are also challenged by the need to optimize the analysis of these time-series in the face of the increasing amount of data. These considerations raised the idea that sharing time-series analysis methods across marine science topics would help scientists and engineers to improve their knowledge of existing methods, optimize the... |

| JERICO Research Infrastructure (RI) is the coastal component of the European marine observing system, and is funded by the FP7 program and recently extended through a newly awarded H2020 project (JERICO-NEXT). It gathers 33 partners from 15 European countries. This research infrastructure aims at further developing, harmonizing and integrating nationally funded marine observing systems, collecting physical, chemical and biological parameters from different platforms (ferryboxes, fixed platforms, gliders, HF radars, benthic systems …). The General Assembly was the first part of this “JERICO week”. In this report will be listed all relevant information (agenda, participant list, etc) and the slides of each presentation. The JERICO Management Team would like... |

| A workshop was held on October 16th to 18th 2013 at the Villefranche observatory to outline progress on emerging technologies within the JERICO FP7 project (Work-package 10). A particular focus of the workshop was to invite researchers outside the project consortium to: • Learn of technology developments within JERICO and • Present results of their own experiments and technology development The workshop was a mixture of invited talks and practical demonstrations of some of the technologies involved. There were a total of 24 invited talks and 2 additional practical demonstrations. The talks focused on 5 key tasks within the emerging technologies area: 10.1 Biological compartments 10.2 Contaminants 10.3 Profiling technologies 10.4 Ships/vessels of... |
