[CIG-ALL] SELEN 2.9 Release

[Eric Heien]

Greetings,

I am pleased to announce the release of SELEN 2.9: a program for solving the “Sea Level Equation”. This is the first release of SELEN through Computational Infrastructure for Geodynamics (CIG).

The open source program SELEN solves numerically the so-called "Sea Level Equation" (SLE) for a spherical, layered, non-rotating Earth with Maxwell viscoelastic rheology. The SLE is an integral equation that was introduced in the 70s to model the sea level variations in response to the melting of late Pleistocene ice sheets, but it can also be employed for predictions of geodetic quantities in response to present-day melting of continental ice-sheets.

SELEN can compute vertical and horizontal surface displacements, gravity variations and sea level changes on a global and regional scale. SELEN (acronym of SEa Level EquatioN solver) is particularly oriented to scientists at their first approach to the glacial isostatic adjustment (GIA) problem and, according to our experience, it can be successfully used in teaching. The current release (2.9) considerably improves the previous version of the code in terms of computational efficiency, portability and versatility.

You can download the source code and manual from:

Detailed installation instructions for compiling and running the SELEN package are in the User Manual as well as several examples and background material. Thanks to Daniele Melini and Giorgio Spada for their hard work in writing and preparing the software for a broader distribution.

Best wishes,

Eric Heien
