The relationship between climatic/environmental signals from high resolution snow pit studies and meteorological conditions
Listed in NASA Earthdata CMR
Metadata record for data from ASAC Project 1172 See the link below for public details on this project. ---- Public Summary from Project ---- The aim of ice core drilling is to extract information which aids in the reconstruction of past climatic conditions.
Description
There has been limited research, however, towards calibrating records preserved in the ice sheet with atmospheric conditions. The intention of this project is to conduct a detailed study of individual snowfall events in the upper few meters of snow and their relationship with observed meteorological conditions during the events.
Na, Ca, Cl, K, Mg are all sea salt indicator species. NO3 is a summer marker (debate exists on the primary source of this species). Work has been carried out over three field seasons to date. 1999/2000, 2001/2002, 2004/2005.
