Welcome to ERSEM’s documentation!

Tests Documentation Status

ERSEM is a marine biogeochemical and ecosystem model. It describes the cycling of carbon, nitrogen, phosphorus, silicon, oxygen and iron through the lower trophic level pelagic and benthic ecosystems.


We strongly encourage everyone using the ERSEM code to register as a user by filling a short registration form. We’d love to get a better understanding of who is using the ERSEM code and for what applications, as it will help us to provide the best support to the user community. It will also allow you to receive information and news on the latest model developments.
