Fortnightly tidal asymmetry inversions and perspectives on sediment dynamics in a macrotidal estuary (Charente, France)
Tidal asymmetry is a phenomenon that characterises estuarine hydrodynamics and has a strong impact on sediment dynamics. Extensive research has been dedicated to studying tidal dynamics in…
Sea level extremes in the Caribbean Sea
Sea level extremes in the Caribbean Sea are analyzed on the basis of hourly records from 13 tide gauges. The largest sea level extreme observed is 83 cm at Port Spain. The largest nontidal…
Storm impact on the seasonal shoreline dynamics of a meso- to macrotidal open sandy beach (Biscarrosse, France)
A three-year dataset (2007–2010) of shoreline and sandbar positions derived from video observations of an open sandy beach (Biscarrosse, France) is analyzed, to explore the impact of storms on the…
Levelling co-located GNSS and tide gauge stations using GNSS reflectometry
The GNSS reflectometry technique provides geometric information on the environment surrounding the GNSS antenna including the vertical distance to a reflecting surface. We use sea-surface…
Simulations of direct and reflected wave trajectories for ground-based GNSS-R experiments
The detection of Global Navigation Satellite System (GNSS) signals that are reflected off the surface, along with the reception of direct GNSS signals, offers a unique opportunity to monitor water…
Évolution des périodes de retour des évènements franchissant avec le changement climatique
L'une des conséquences du changement climatique est la remontée du niveau moyen des mers. C'est cette conséquence qui est prise pour hypothèse principale dans ce travail. La méthode utilisée pour…
Circulation around La Réunion and Mauritius islands in the South-Western Indian Ocean: a modeling perspective
The objective of this study is to document the circulation in the vicinity of La Réunion and Mauritius islands, i.e., within 500 km offshore, on the intraseasonal time scale, using a high-…
PREVIMER: Improvement of surge, sea level and currents modelling
The pre-operational system PREVIMER provides coastal observations and forecasts along French coasts. It provides, among other variables, currents, sea levels, surges and waves. This paper…
Trophic role of large benthic sulfur bacteria in mangrove sediment
Large filamentous sulfur-oxidizing bacteria belonging to the Beggiatoacae family can cover large portions of shallow marine sediments surrounding mangroves in Guadeloupe (French West Indies). In…
Atmospheric storm surge modeling methodology along the French (Atlantic and English Channel) coast
Storm surge modeling and forecast are the key issues for coastal risk early warning systems. As a general objective, this study aims at improving high-frequency storm surge variations modeling…
