High resolution snow pit sampling at Victoria Lower and Evans Piedmont Glacier
High resolution snow pit sampling at Victoria Lower and Evans Piedmont Glacier
Intermediate length cores were recovered from Victoria Lower Glacier and Evans Piedmont Glacier in 2001/02 and 2004/05, respectively. High resolution samples from shallow snow pits are used to update the records and to investigate post-depositional changes in the snow signal, such as isotopic diffusion or nitrate loss. Furthermore, meteorological data recorded at Evans Piedmont Glacier and re-analysis data are used to calculate transfer functions and establish seasonality in the ice core record. In order to estimate the influence of small-scale local page 3 influences such as sastrugi features, we investigate spatial variability by studying physical properties of multiple snow pits at each location.
