GeoChronR and ChronRater: New tools for quantifying, analyzing and visualizing the impacts of age uncertainty of time-uncertain geoscientific data (Nick McKay, Northern Arizona University)
GeoChronR is a new project that is developing an integrated framework that allows scientists to generate state-of-the-art age models for their records, create time-uncertain ensembles of their data, analyze those ensembles with a number of commonly-used techniques, and visualize their results in an intuitive way. The code will be developed as a package in the open-source and community-supported R platform. ChronRater is a complementary tool that aims to quantify the factors that scientists understand to influence age uncertainty, but that are difficult or impossible to quantify using available statistical procedures. This flexible algorithm provides a semi-quantitative rating of an entire chronology, which is particularly useful when applied uniformly to a large database to stratify the records by their qualitative age certainty.
GeoSoft - a community software commons for the geosciences (Yolanda Gil, University of Southern California) http://www.geosoft-earthcube.org/ Geosciences software embodies important scientific knowledge that should be explicitly captured, curated, managed, and disseminated. Recurring issues of provenance and uncertainty in the context of data could be better addressed with improved treatment of geoscience software: it is easy to see that nothing describes data more precisely than the software that generates or uses the data. The goal of the GeoSoft project is to enable the creation of a germinal ecosystem for software stewardship in geosciences that will empower scientists to manage their software as valuable scientific assets in an open transparent mode that enables broader access to that software by other scientists, software professionals, students, and decision makers.
