A projection of larval dispersal patterns of Atlantic cold seep mussels Gigantidas childressi, G. mauritanicus, Bathymodiolus heckerae and B. boomerang was carried out for the next 50 years under the constraint of global warming predicted by the IPCC for the most pessismistic scenario. Simulations were run at +00 years, +25 years and +50 years from initial years of 2014 to 2019 (+00Y) at 21 locations on the US, European and African coasts using the VIKING20X model, in which the Atlantic water temperatures predicted by the FOCI model were forced to the future dates. The dataset consists of a number of 5775 simulations carried out over 5 years X 5 spawning dates per prediction period (+00Y, +25Y, +50Y) with, for predictions at +25Y and +50Y, a repetition of simulations per quantile (0.025, 0.16, 0.5, 0.67 and 0.975) to take into account for the most extreme variations in water mass temperatures predicted by the FOCI model for a given date. ... : All simulations are contained within one large (ca. 8.4 GB) netCDF file named: trajs_viking_with_FOCI_anomalies.ncThe netCDF file contains 5775 larval dispersal simulations done by VIKING20X for the North Atlantic water masses temperatures predicted by FOCI at +00Y (2014, 2015, 2016, 2017, 2018 and 2019), +25Y (2039, 2040, 2041, 2042, 2043, and 2044) and +50Y (2064, 2065, 2066, 2067, 2068 and 2069) for 21 seep localities and 5 spawning dates per year. Simulations follow Lagrangian trajectories of 1000 particles over 333 days with a alive/dead threshold above water temperature greater than 20°C. ...
