This dataset contains spatial projections (.asc files) of biodiversity metrics
(alpha, beta and gamma diversity Hill number 0, plus the regional fraction of
rare species) for 4 assemblages: zooplankton, phytoplankton, benthos and fish,
for years 1993-2099, across the shared socioeconomic pathways (SSP) climate
scenarios SSP1-2.6, SSP2-4.5, and SSP5-8.5 (Chapter 4 | Climate Change 2021: The Physical Science Basis_), over the NE Atlantic region
(Kristiansen et al. 2024). These projections were made in order to investigate
biodiversity change across metrics and assemblages into the future, to
demonstrate the shifting baseline of diversity due to climate change. There is
one .asc file for each biodiversity metric, assemblage, climate scenario and
year. These datasets relate to the manuscript: Fromplanktonto
fish: 21st-century redistribution of marine biodiversity and the changing
role of rare species, Couce, E. & Greig, L. et al. 2026 (recently submitted
).
