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.

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 Oceanus2000 website.



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 program.

DB2000 (beta version)

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 program.
