Sampling on the Ganges and Brahmaputra Rivers
The final phase of our revolves around visiting chars, sandy river islands, on the Ganges and Brahmaputra River. Chris and Dan are making measurements of soil salinity and moisture and spectra of the soil reflectance, while Liz and I collected samples for OSL dating and understanding the OSL properties of the river sediments here. This…
