- Abstract
-
The Observatory of Water and Erosion in the Antilles (Observatoire de l’Eau et de l’éRosion aux Antilles - ObsERA) is a National Observation Service (SNO) of the CNRS-INSU, and one of the components of the OZCAR Research Infrastructure. ObsERA involves teams from the Institut de Physique du Globe de Paris and the Laboratoire de Géologie de Lyon, Terre Planètes Environnement (UMR 5276, Observatoire des Sciences de l'Univers de Lyon).
ObsERA has the following objectives : (1) to monitor physical and chemical erosion and investigate how they influence biogeochemical cycles, in the specific context of a tropical volcanic island; (2) to understand how extreme events (flash floods, tropical storms, earthquakes...) influence biogeochemical cycles (such as the carbon cycle), denudation rates and landscape morphology; (3) to document the response of tropical watersheds to the ongoing climate change; (4) to promote the development of new tools and methods to survey the evolution of the critical zone.
To achieve these objectives, ObsERA monitors the evolution of environmental variables (rainfall, river discharge, dissolved and solid transport in rivers, chemical composition of soils, river and rainfall…) in four catchments of Basse-Terre Island, a volcanic island in the Guadeloupe archipelago (Lesser Antilles). ObsERA also documents the evolution of the sediment grain size and the morphology of several rivers, based on aerial images acquired with a drone. The data produced by ObsERA are made freely available to the scientific community through the webobsera platform : http://webobsera.ipgp.fr/. - Creators
