Providing Decision Support for Cosmogenic Isotope Dating
to AI. An automated tool can do boring and repetitive reasoning, freeing experts to do more difficult and creative work. Indirectly, it can make explicit the knowledge and reasoning used by experts in the field. Finally, an automated tool can consider all possibilities, sometimes exploring scenarios that human experts may miss. This article discusses automating reasoning for dating geological l...
متن کاملCalvin: A System for Automating Cosmogenic Isotope Dating
Scientific reasoning is a complex process, alternately requiring flashes of insight and tedious analysis. This dichotomy is evident in constructing a geologic timeline for a landform using cosmogenic isotope dating. Experts in this field frequently spend months on repetitive mathematical tasks, until they have gathered enough information to suddenly understand the data. The Calvin project 1 is ...
متن کاملEvidence of early Holocene glacial advances in southern South America from cosmogenic surface-exposure dating
Cosmogenic nuclide surface-exposure dating reveals that glaciers in southern South America (468S) advanced ca. 8.5 and 6.2 ka, likely as a result of a northward migration of the Southern Westerlies that caused an increase in precipitation and/or a decrease in temperature at this latitude. The older advance precedes the currently accepted initiation of Holocene glacial activity in southern South...
متن کاملDeciphering boulder mobility and erosion from cosmogenic nuclide exposure dating
[1] Large boulders are prominent features in many geomorphic systems and are frequently targeted for cosmogenic exposure dating. Presently, there are little data or theory predicting exposure age, erosion rate, and mobilization frequency of boulders in environments such as channels, talus slopes, or moraines. Here we explore the potential for cosmogenic isotope analysis to constrain the transpo...
