However, the robustness of this method across a wide range of systems remains to be shown. We measured CDOM fluorescence and DOC concentration in four tropical freshwater and coastal environments (estuary and coastal, tropical shallow lakes, water from the freshwater lens of two small islands, and soil leachates). We found that although this method can provide an estimation of DOC concentration in sites with low variability in DOC and CDOM sources in systems where the variability of DOC and CDOM sources are high, this method should not be used as it will lead to errors in the estimation of the bulk DOC concentration. specialized Chromophoric dissolved organic matter Dissolved organic carbon Ecosystem Fluorometer VIET NAM ZIMBABWE NOUVELLE CALEDONIE 036 186 1 589-596 2014 0167-6369 https://www.documentation.ird.fr/hor/fdi:010061365 10.1007/s10661-013-3401-2 0167-6369 [F B010061365] https://www.documentation.ird.fr/hor/fdi:010061365 https://www.documentation.ird.fr/intranet/publi/depot/2014-05-22/010061365.pdf Accès réservé (Intranet de l'IRD) IRD - Base Horizon / Pleins textes 2014-02-05 2017-08-23 fdi:010061365 fre
