Introduction
This page provides links to a variety of software resources that, I hope, will be useful in Geology, Geophysics and Astrobiology.
School Seismology Programme
The British Geological Survey’s schools’ seismology project is a programme to put affordable but effective earthquake detectors into schools across the country. My school seismology page contains a powerpoint presentation showing what the system can do and a computer exercise illustrating use of the associated software (no seismometer necessary).
My Software
I have developed a range of JavaScript-based programs for performing various modelling and analysis tasks in Geology and Geophysics. Using Javascript means that the resulting apps work equally well on PCs, Macs, Tablets or even Smart-Phones provided they are using modern browsers. If you experience problems with the appearance, try upgrading your browser. Currently available programs perform:
Milankovitch: Calculation of ancient Milankovitch cycle periods and their uncertainties.
Anthropogenic Climate Change: Test the hypotheses that humans are the cause of rising carbon-dioxide in the atmosphere and that this, in turn, explains rising temperatures.
DeltaModelling: Forward modelling of deltas to illustrate the effects of changing sea-level and sediment supply on the resulting stratigraphy.
HangingWall: Forward modelling of Hangingwall Deformation (deformation of strata during movement on faults).
ReservoirFlowModel: Forward modelling of hydrocarbon flow through the subsurface. Program demonstrates the effects of faults, channels and impermeable beds as well as the consequences of “upscaling”.
ShotRecordSimulator: Forward modelling of the acquisition of a Marine Seismic Shot Record. Program demonstrates the different events detected, the effects of ghosts and the influence of subsurface properties.
VelocityAnalysis: A program to illustrate the velocity analysis of a CMP gather. Program shows the effects of NMO/Stacking and allows the user to pick the best velocity and mute parameters.
All programs are released under a creative-commons Attribution-NoDerivatives licence. Further programs will be added to this list as they become available.
