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.

Dec 2, 2021
This version of the model was runs with the darwin3 version of the darwin model (available at https://github.com/darwinproject/darwin3). The model is based on Dutkiewicz et al (2021) and resolves the cycling of carbon, phosphorus, nitrogen silica, iron, and oxygen through inorganic, living, dissolved and particulate organic phases (including CDOM)....

Output from ECCO2/GUD simulation. This simulation includes 35 phytoplankton types grouped into 6 different Phytoplankton types and spanning from a cell diameter of 0.6μm to 200 μm. The movie shows four different phytoplankton functional types superimposed over Chl concentrations (white intensity). Red=diatoms; pink=Coccolithophores; green=picophyto...

Ecological Provinces from a computer simulation of the marine global ecosystems. Each color represents a different distinct combination of the most dominant phytoplankton function types (as shown in the Venn diagram top right). The opacity indicates the total concentration of phytoplankton biomass: the darker the color, the less phytoplankton – Ani...
