Reconstructing central African hydroclimate over the past century using freshwater bivalve shell geochemistry by Z. Kelemen, D. P. Gillikin, S. Bouillon

“…Thus, while the freshwater shell <span class="inline-formula"><i>δ</i>¹⁸O</span> patterns are consistent with the documented long-term <span class="inline-formula"><i>Q</i></span> changes in the Oubangui, the shells show that the most pronounced changes in hydroclimate over the past century are expressed in low-flow sections of the hydrograph and likely result from a combination of changes in the rainfall regime, aquifer recharge, and/or vegetation cover in the upper catchment. …”
