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 (E2K)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 (B2K)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. |
 |
Oceanus2000Oceanus2000 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 Oceanus2000 website. |
| Download Equation2000 |
Equation2000Equation2000 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 program. |
| Download DB2000 (beta version) |
Data Builder 2000DB2000 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 program. |
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. Some of these files are shareware, so if you use them be sure to register the programs with the authors.
