  1. CRONUS Web Calculators(formerly ‘Stone Age’) • Important need at present: • Rate of publication of exposure-dating papers is big. • most present applications by nonspecialists are exposure ages and erosion rates. • these lack a common basis for the calculations: results in proliferation of inconsistent results. • many users aren’t familiar with the basic calculation tools. • Rapid and useful deliverable to user community

  2. Initial goals: • 1. Compute P(z) for Al-26, Be-10, Cl-36, (and He-3) • 2. Compute simple exposure ages and/or steady-state erosion rates therefrom. • Summary: provide basic functions to satisfy majority of straightforward applications. Make framework that can be expanded to include improvements in future years.

  3. Design -- • Running on MATLAB web server • Easy language to learn • Ingests and regurgitates basic HTML • Eliminates unpleasant CGI/Java/whatever coding • Already in use by most CRONUS folks • Modular design -- • All functions replaceable with improved versions • Anyone can contribute a function with specified I/O • Well-documented • Emphasis on organization, documentation, clarity, separability rather than computational speed

  4. Example -- P(z) for Cl-36

  5. Plan -- • Buy LINUX server -- housed/maintained at UW • Implement basic Be-10, Al-26, Cl-36 production rate, exposure age, and steady erosion rate calculators • Mainly relies on pre-existing code at UW; contributions solicited • Target spring/summer 2005 • Circulate internally • CRONUS folks to test; discussion of model/parameter choices • Notify public via publication (in online journal), and open web site to users. Release all MATLAB functions to public. • Target summer/fall 2005…

  6. Issues…. • Data reporting and referencing in published work. • Suggestion: Calculations receive unique number when requested, at which point the data and calculation parameters are archived on the web site, and can be referenced in the publication/retrieved by readers. • Archived data/parameters can be recalculated later to reflect improvements. How to handle this? • Basin-averaged production rates. • High demand. Much bigger challenge to centralise. Maybe just offer MATLAB/ARC/GMT/whatever code to do this offline. • Where does the calculation start? • 10/9 ratio or atoms/g Be-10? • (problem: correlated [Cl], [Cl-36] errors…) • Coordination with PRIME/LLNL reporting schemes?
