Abstract. During the last 15 years, substantial progress has been achieved in altimetry data processing, now providing data with enough accuracy to illustrate the potential of these observations for coastal applications. In parallel, new altimetry techniques improve data quality by reducing land contamination and enhancing the signal-to-noise ratio. Satellite altimetry provides more robust and accurate measurements ever closer to the coast and resolve shorter ocean signals. An important issue is...

Twenty-year coastal altimetry data set (X-TRACK) is used, for the first time, to gain insight into the long-term inter-annual variations of the surface circulation in the Sicily Channel. Firstly, a spectral along with a time/space diagram analysis are applied to the monthly means of the X-TRACK geostrophic currents over the period 1993-2013. They reveal a regionally coherent current patterns from track to track with a marked inter-annual variability that is unequally shared between the Atlantic ...

The use of High Frequency ocean Radars (HFR) as a research and monitoring tool for the observation of the coastal ocean has steadily developed throughout the world over the last decades, especially in the US where more than one hundred sites are currently maintained in a multi-purpose operational network (https://ioos.noaa.gov/project/hf-radar/) all over the country coasts. Such a networking effort is currently being built at the EU level through the JERICO-Next H2020 program in link with Euro-G...

Technological advances in the recent satellite al-timeter missions of Jason-2, SARAL/AltiKa and CryoSat-2 have improved their signal-to-noise ratio, allowing us to observe finer-scale ocean processes with along-track data. Here, we analyse the noise levels and observable ocean scales in the northwestern Mediterranean Sea, using spectral analyses of along-track sea surface height from the three missions. Jason-2 has a higher mean noise level with strong seasonal variations, with higher noise in w...

This work is the first study exploiting along track altimetry data to observe and monitor coastal ocean features over the transition area between the western and eastern Mediterranean Basins. The relative performances of both the AVISO and the X-TRACK research regional altimetric data sets are compared using in situ observations. Both products are cross validated with tide gauge records. The altimeter-derived geostrophic velocities are also compared with observations from a moored Acoustic Doppl...

A Mediterranean Ocean Observing System for the Environment (MOOSE) has been set up as an interactive, distributed, and integrated observatory system of the North West Mediterranean Sea in order to detect and identify long-term environmental anomalies. In this framework, the Mediterranean Institute of Oceanography (MIO) operates two couple of High Frequency Surface Wave Radars (HFSWR). HFSWRs provide synoptic observations of sea surface currents with high temporal (0.25-1 h) and spatial (1-3 km) ...

In the framework of the French MOOSE project (Mediterranean Ocean Observing System on Environment), the Mediterranean Institute of Oceanography is operating HF radars on the North Western Mediterranean coast. The surface circulation in this region is characterized by a large-scale flow (Northern Current) and by a broad range of other scales of variability induced by meteorological and tidal forcing. The ability of HF radars is to provide synoptic observation as sea surface current map every hour...

The Northern current is the main circulation feature of the North-Western Mediterranean Sea. While the large-scale to mesoscale variability of the northern current (NC) is well known and widely documented for the Ligurian region, off Nice or along the Gulf of Lions shelf, few is known about the current instabilities and its associated mesoscale dynamics in the intermediate area, off Toulon. Here, we took advantage of an oceanographic cruise of opportunity, the start of a HF radar monitoring prog...

Cet article a pour but de presenter les grandes lignes du fonctionnement de la circulation marine et atmospherique de la Mediterranee, afin de mieux comprendre les phenomenes physiques qui affectent les iles d'Hyeres, d'optimiser la gestion de leur environnement et le cas echeant des risques potentiels. Mots-cles : Mediterranee, iles d'Hyeres, Port-Cros, circulation des masses d'eau, courant, vent, etat de mer, circulation atmospherique, moyenne echelle. Abstract. The Hyeres Archipelago in the m...

We present a first attempt of simulating the sympagic and planktonic production cycles in the Hudson Bay marine system (HBS) driven by ice cover duration and local hydrodynamics with the help of a 3D coupled biological–physical model. The simulation shows a marked spatial variability of ice and planktonic production and associated carbon fluxes, suggesting the co-existence of several sub-systems in the HBS. Among these, the “low ice–high mixing” Hudson Strait sub-system is characterized by high ...
