Solid Earth Teaching and Research Environment

A software product by USC Geodynamics. 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)

SEATREE is module based, and the current SVN version includes tools for computing 2D mantle convection, 3D body wave mantle seismic tomography, 3D 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 3D 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

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 is being developed mainly by a USC Geodynamics team since the Fall of 2007 thanks to NSF CAREER funding and the additional support of the Department of Earth Sciences at the University of Southern California, Los Angeles.
