Saint Helena Island StrathE2E Implementation files

Model implementation files for the Saint Helena Island for use with the StrathE2E R package (for package details, see Heath et al., 2020, Methods in Ecology and Evolution, doi:10.1111/2041-210X.13510). This configuration was developed with StrathE2E version 4.0.1 and supports decadal simulations from a historical baseline (2010–2019) through to future projections covering the 2060s. Parameterization was based on outputs from two coupled physical-biogeochemical models (NEMO-ERSEM), driven by two atmospheric models (GFDL and CNRM), and incorporating two Shared Socioeconomic Pathways (SSP1-2.6 and SSP3-7.0). This enables scenario-based projections of ecosystem dynamics under different climate futures. A detailed implementation document accompanies the model files, describing the parameterization approach and data sources used for model calibration across both baseline and future periods. This repository will be made publicly available following the acceptance of the paper Olher et al. (2025), “Severe biomass declines in the St Helena Marine Protected Area food web due to climate change,” to be published in Limnology and Oceanography Letters. This implementation was developed under the EU H2020 Mission Atlantic project (grant agreement no. 862428).
