The Darwin Project is an initiative, based at Massachusetts Institute of Technology, to advance the development and application of novel models of marine microbes and microbial communities, identifying the relationships of individuals and communities to their environment, connecting cellular-scale processes to global microbial community structure. More details of the project can be found at http://darwinproject.mit.edu/

Part of this project includes the development of the DARWIN marine ecosystem model that is part of the MITgcm (http://mitgcm.org). Code can be downloaded from that website.

There are several version of the DARWIN model, and it continues to evolve. The purpose of this dataverse is to provide output and model code and input fields from various version of the DARWIN model.

GUD IGSM monthly mean plankton group surface biomass
Sep 6, 2023 - GUD IGSM
Dutkiewicz, Stephanie, 2021, "GUD IGSM monthly mean plankton group surface biomass", https://doi.org/10.7910/DVN/RPL6PT, Harvard Dataverse, V2
Each files contains 12 monthly mean for each year 1991 to 2100 of surface biomass (mmol C/m3): Photosynthetic prokaryotes, pico-eukaryotes, coccolithophores, diazotrophs, diatoms; mixotrophic dinoflagellates; zooplankton. Note that the atmospheric-ocean component of the earth system model used to produce the forcing fields has its own internal inte...

Darwin3 31+16+3 (Interactions)(Massachusetts Institute of Technology)
Mar 28, 2023
This version of the model was runs with the darwin3 version of the darwin model (available at https://github.com/darwinproject/darwin3). The model resolves the cycling of carbon, phosphorus, nitrogen silica, iron, and oxygen through inorganic, living, dissolved and particulate organic phases (including CDOM). The biogeochemical and biological trace...
