Using stable water isotope composition (δ18O and δ2H) to track the interannual responses of Arctic and tropical Andean water bodies to rising air temperatures
Lakes in the Arctic and tropical Andes are experiencing some of the largest temperature increases on the planet with coeval marked limnological changes, but little data exist on water balance parameters from these regions. Here, we present a unique data set of water stable isotope composition (δ18O...
