Environmental Records In A High-Altitude Low-Latitude Glacier, Sierra Nevada, California, Alison J. (Alison Jane) Gillespie

Glaciers are sensitive and detailed recorders of changes in local, regional, and global climate. Stable isotope variations reflect seasonal temperature changes, physical stratigraphy relates to net precipitation, and trace element concentrations mark seasonal surfaces in the ice. Previous studies have largely focused on polar ice cores because cold, dry conditions in such locations are ideal for preserving ice stratigraphy. Conversely, low-latitude alpine glaciers have been generally ignored because warmer, wetter conditions in them have been presumed to destroy or obscure the original stable isotope stratigraphy. Here, I evaluate the potential to obtain viable environmental records from an ice core of …
