In February 2025, H. VanderZanden enhanced the MITgcm-contrib/ecco_darwin repository by developing new biogeochemical model features in Fortran, focusing on sediment nutrient fluxes and explicit plankton mortality processes. By integrating a sediment nutrient fluxes module and a kill plankton mortality module into the DARWIN framework, VanderZanden improved the model’s representation of nutrient cycling and plankton dynamics. Updates to the RADIv2 metamodel and its parameter files expanded the model’s configurability, supporting more realistic coastal and ecosystem simulations. This work demonstrated depth in biogeochemical and climate modeling, delivering a robust foundation for researchers studying oceanographic nutrient and ecosystem processes.
