Core Ideas OZCAR is a network of sites studying the critical zone. covers various disciplines. will help disciplines to work together for better representation and modeling The French zone initiative, called (Observatoires de la Zone Critique–Application et Recherche or Critical Observatories–Application Research) National Research Infrastructure (RI). OZCAR‐RI instrumented sites, bringing 21 pre‐existing research observatories monitoring different compartments situated between “the rock...
Over the past two decades, La Soufrière volcano in Guadeloupe has displayed a growing degassing unrest whose actual source mechanism still remains unclear. Based on new measurements of chemistry and mass flux fumarolic gas emissions from volcano, here we reveal spatio-temporal variations features that closely relate to 3D underground circulation fluids, as imaged by electrical resistivity tomography, geodetic-seismic signals recorded over decades. Discrete monthly surveys plumes various...
Weathering of volcanic rocks accounts for approximately one third global CO2 consumption in the silicate weathering cycle1. Tropical islands contribute to this process due their extreme denudation rates, thought be mainly driven by high and episodic precipitation, which may sustain fluxes. However, how total (D) divides into erosion (E) (W) fluxes, factors governing long-term rates on tropical remain unclear. This uncertainty arises from lack methods quantify these over centennial millennial...
Abstract Atmospheric mineral dust deposition is an important source of nutrients for ocean and tropical island ecosystems. Direct measurements are generally more reliable at local scale than models, even those based on aerosol concentration measurements. Whatever the scale, relevant observations necessary model evaluation. We present here results obtained by direct measurement atmospheric aerosols total using a 14‐month time series from Caribbean region. Total velocity, lifetime, scavenging...
Abstract Catchments respond to rainfall by storing and releasing water according their internal dynamics. Groundwater had long been treated as the slow reservoir in this process, but isotopic measurements showed how responsive it can be. Here, we investigate mechanics of groundwater's contribution floods. To do so, monitored over 3 years shape table in, runoff out of, a small tropical catchment. We find that groundwater within minutes event. Using an asymptotic theory inspired recent...
Abstract Dust emitted from North Africa is transported over long distances and has a strong impact on large areas the Tropical Atlantic Ocean. Sea salt by sea surface second source of essential elements in atmosphere plays major role cycles alkaline‐earth metals ecosystems tropical Islands. The total atmospheric deposition fluxes were continuously sampled weekly basis Guadeloupe, Lesser Antilles, March 2015 to August 2018 (41 months). Elemental fluxes, including Al, Ca, K, Mg, Fe, Na, P, S,...
