Integral to the paleoclimate research has been glaciological and climate investigations. For example, numerous short cores have been drilled to depths of 10-20 m at several ice cap sites, over the past 30 years. Beginning in 1976, scores of ablation stakes and snow pits have provided a better understanding of variability in snow chemistry and accumulation. Also in the late 1970s, meteorological instrumentation was deployed at the summit to characterize the largely-unknown climate at high elevations in the Andes. This aspect was carried out collaboratively with Stefan Hastenrath, working with equipment considered incredibly primitive – and unreliable – by today’s standards.
During this 2003 expedition meteorological measurements resumed, with modern electronics and satellite telemetry. The University of Massachusetts automated weather station (AWS) continues to provide data from a comprehensive suite of sensors (see image below), helping to establish the climate of Quelccaya Ice Cap.
