Location
Guadeloupe is a volcanic island submitted to humid tropical climate. Geology is pyroclastics, basalts and andesites. Age of rocks ranges from modern to 3 Ma according to a South-North age (and elevation) gradient. A strong precipitation gradient occurs between the East Coast (exposed to trade winds) and the mch more drier West Coast. Max. precipitations are 10 m at the top of the volcanoe, La Soufrière. The Capesterre watershed is monitored automatically and two lysimeter systems are ued to monitor soil solution profiles in Capesterre and Bras David Watersheds. Bras David watershed and Vieux Habitant watershed are sampled regularily. Analyses include major cations and anions, silica, organic matter, trace elements and a couple of isotopic ratios.
