GEM has produced a number of software
utilities with wide-ranging applications in oceanography and ecological modelling. Here
you can find more information about them, and download freeware versions.
EcoWin2000 is an object-oriented ecological
modelling package, developed at GEM for advanced ecological modelling work. Features
include several sub-model components simulating variables such as hydrodynamic transport,
nutrients, phytoplankton, and many more. More information is available at the E2K website.
BarcaWin2000 is a relational water quality
database, developed at GEM, which includes the features most used in oceanographic data
analysis. Please visit the B2K website for more information.
Oceanus2000 is a package for making
oceanographic tables, tide prediction, and even for looking at the phases of the moon. It
is a product of the ecological modelling work at GEM; download it for free at the
Equation2000 is a package for
calculating an index of estuarine quality. There is an accompanying paper to the index:
Ferreira, J.G., 2000. Development
of an estuarine quality index based on key physical and biogeochemical features. Ocean
& Coastal Management, 43/1, 99-122. Please download the file, and run the setup
Data Builder 2000
DB2000 is a package for
interconverting different file formats, interpolation, and more. The beta version is
available for download from the link below. Please download the file, and run the setup
The links below are for simple PowerSim and
Stella models available for free download. They were written for teaching purposes, for
final year undergraduate and M.Sc. students. You will need a copy of the PowerSim (TM) or
Stella (TM) software as appropriate.
This page contains a number of utilities
which are available for downloading, including ftp software, anti-viruses and other files.
