In this chapter we report on the RepTool, a computer based tool for the collection, analysis, and presentation of data about " workscapes ". Users of the tool collect relevant information about workplaces and workpractices in a central data structure on which the tool provides different views. Physical, social, and cognitive spaces in users' or customers'(More)
In recent decades the West Antarctic Ice Sheet has experienced warming and glacial retreat. Despite receiving growing attention, knowledge of glacial dynamics in this region remains limited. Snow accumulation data is sparse and fails to capture true spatial variability. A shallow firn core, drilled at the triple ice divide between Pine Island Glacier,(More)
The spatial representation of accumulation measurements is a major limitation for current glacier mass balance monitoring approaches. Here, we present a method for estimating annual accumulation rates on a temperate Alpine glacier based on the interpretation of internal reflection horizons (IRHs) in helicopter-borne ground-penetrating radar (GPR) data. For(More)
Exploitation of the extensive polymetallic deposits of the Andean Altiplano in South America since precolonial times has caused substantial emissions of neurotoxic lead (Pb) into the atmosphere; however, its historical significance compared to recent Pb pollution from leaded gasoline is not yet resolved. We present a comprehensive Pb emission history for(More)
The importance of metallurgy for social and economic development is indisputable. Although copper (Cu) was essential for the wealth of pre- and post-colonial societies in the Andes, the onset of extensive Cu metallurgy in South America is still debated. Comprehensive archaeological findings point to first sophisticated Cu metallurgy during the Moche culture(More)
