Solid Earth Teaching and Research Environment
Partial support through NSF-CAREER.
SEATREE is a modular and user-friendly software to facilitate using solid Earth research tools in the classroom and for interdisciplinary, scientific collaboration. We use python wrappers and make use of modern software design concepts, while remaining compatible with traditional scientific coding. Our goals are to provide a fully contained, yet transparent package that lets users operate in an easy, graphically supported "black box" mode, while also allowing to look under the hood. In the long run, we envision SEATREE to contribute to new ways of sharing scientific research, and making (numerical) experiments truly reproducible again (Eos Article). For the current development status, see the main software download page.
SEATREE is module based, and the current Github version includes tools for computing 2-D mantle (thermal) convection, 3-D body wave mantle seismic tomography, 3-D spherical mantle flow, for inverting for Earth structure by means of surface wave, phase velocity tomography, and a two-dimensional synthetic tomography teaching module. A rudimentary module for earthquake location inversions is also available. The main software design consists of transparent python wrappers that drive the modules, including a GMT plotting tool, a VTK/Paraview 3-D visualization interface, and a graphical user interface.
SEATREE is freely available under the GNU license; a desktop installation is required to use SEATREE right now but we are planning on a web-based version as well. We encourage you to take the software for a test drive. If you want to use SEATREE in a classroom setting, we might be able to offer you some installation support and always welcome your feedback. Also, if you like to add your own module to SEATREE, please let us know; we might be able to provide some assistance.

Modules
The SEATREE graphical user interface and our python wrappers provide access to the following computational tools which are provided and shared by different groups of researchers.
Geodynamics
- hc
- A Hager & O'Connell (1981) mantle flow computation tool for spherical mantle circulation that allow computing flow velocities, tractions, and the geoid given different tomographic models.
- conman
- 2D thermal convection module based on ConMan
Seismology
- larry3d
- a toolkit for performing 3-D, global body wave tomography for the Earth's mantle
- larry
- a toolkit for performing 2-D, global, surface wave phase velocity tomography
- Syn2D
- a synthetic 2-D seismic tomography tool
- Modules under development
-
- nonlinloc: non linear earthquake relocations using NonLinLoc (initial stages)
Visualization
SEATREE provides access to different ways of visualization computational module output, some modules support more than one way of plotting results.
- GMT
- many modules use GMT for plotting geographic data (as for hc and larry), we wrote a simple python interface.
- MatplotLib
- Matlab-like output, used for syn2d and ConMan
- Paraview
- Interactive 3-D output via VTK, now available for latest version of the hc module, and in the works for larry3d
Contributors
SEATREE has been developed since the Fall of 2007 thanks to NSF CAREER funding and the additional support of the Department of Earth Sciences at USC, Los Angeles, and now from UT Austin.
SEATREE design and coding
- Kevin Milner (main Python code design and support)
- Thorsten Becker (project lead, module and some python programming)
- Francois Cadieux (larry3d python module and VTK interfacing)
- John Yu: Distributed Linux cluster installation, UGESCE implementation, and additional coding
- Hannah Waterhouse and Jared Sain (python code contributions)
- Danijel Schorlemmer: design advice
Module contributors
The meat of SEATREE lies in the underlying research software. Please see the individual module documentation for full references and copyright notices. In particular,
- Larry, larry3D, and Syn2D source codes were generously contributed by Lapo Boschi.
- Surface and body wave velocity measurements were generously contributed by Goran Ekstrom, Christine Houser, Michael Antolik, and Jeroen Ritsema. Original references to the data are provided on the module pages.
- hc is mainly based on advect by Bernhard Steinberger, which was rewritten in C by Thorsten Becker and Craig O'Neill, and the original routines are by Hager & O'Connell (1981).
- nonlinloc uses Anthony Lomax's freely available software packages including NonLinLoc
- conman uses Scott King's software ConMan
