Extreme sea levels on the Atlantic coastline in France: model and observations
Extreme sea levels on the Atlantic coastline in France: model and observations By Etienne CHAUVEAU L'Atlas Bleu / Exploring Extreme sea levels, models and measurements, recent period, Atlantic coast of mainland France. The article identifies the 10 most important storms in terms of marine submersion that have occurred on the Atlantic coasts of mainland France since 1984. It indicates the maximum sea levels recorded during these events. These values are compared with the extreme sea levels (with a 100 years period) derived from the SHOM/CETMEF predictive model. Several observations are drawn
The El Niño phenomenon: a model of global ocean disruption
The El Niño phenomenon: a model of global ocean disruption By Jean-René VANNEY L'Atlas Bleu / Exploring El Niño, climatic disruption, oceanic phenomenon, devastating effect, South America. With two maps and a graph, the article summarizes the principle of El Niño – a climatic disruption whose geographical amplitude and environmental implication are major at a world scale. The sequence of the phenomenon (whose frequency remains poorly known), that occurred in 1982-1983 on the coasts and off the coast of South America, is mapped and analysed specifically.
Natural marine and coastal risks worldwide
What are the major natural risk the coastal zones cope at a global scale? What are their main drivers? The aim of this article is to propose a synthetic analysis and mapping of the different types of risks that occur in coastal zones.
Natural and anthropogenic hazards in tropical seas
This article proposes a synthetic visualisation of the risks weighing on the world intertropical zone. The interactive version of the map brings food for thought on each issue.
