The data comprise hydrometric data and stable isotope data for streamflow and rainfall from the Marolaona catchment in the Ankeniheny-Zahamena Corridor on the Eastern escarpment of Madagascar between February 2015 and March 2016. Rainfall and streamflow were measured at 2 locations, perched water tables at 10 locations, and soil moisture at 3 locations (1 – 3 depths). Samples were taken from streamflow and rainfall for stable isotope (delta-2H and delta-18O) analyses.

Provenance & quality

Stream and groundwater levels were measured with pressure transducers. Precipitation was measured with tipping bucket rain gauges and checked with manual measurements. Soil moisture was measured with capacitance/frequency-domain reflectometry sensors. The water samples were analysed on a Cavity Ring-Down Spectroscope.
The methods are described in more detail in the metadata file (Metadata_Methods_Marolaona.pdf).
