Atlantic seep mussels larval dispersal simulations and genetic data

DOI

These data aim at evaluating the hypothesis of long-distance dispersal across the North Atlantic and the Equatorial Atlantic belt for the cold seep mussels Gigantidas childressi, G. mauritanicus, Bathymodiolus heckerae and B. boomerang. We combined mitochondrial Cox1 barcoding of some mussel specimens from both sides of the Atlantic (American vs European/African margins) with larval dispersal trajectories simulated from the VIKING20X model of the Atlantic circulation at a spatial scale not yet investigated. Larval dispersal modelling data correspond to transports of larvae over one year in surface waters from 21 geographic localities over 5 consecutive years (2015, 2016, 2017, 2018 and 2019) and 5 spawning dates (November, December, January, February and March) per year. Genetic data correspond to the geo-referenced sequences obtained for the 4 mussel species from some of the localities where larvae have been released during the modelling approach.

Larval dispersal modelling data correspond to 525 netCDF files which represent layers with similar fields (f id, obs, traj, age, alive, speed-param, temp, time, z and location). These files contain time-dependent discrete larval numbers over a travelling period of one year according to their age, alive/dead status, temperature and depth at which larvae are found in the water column. The 525 modelling experiments correspond to 21 geographic localities x 5 years x 5 spawning dates per year. A specific upload link has been requested for these files in zip archives.The file Jollivet_et_al_2023_ENA_supplement.txt contains supplementary geo-referenced sequences of seep mussels with Biosample ID, sequence ID, sequence N°accession, species name, geographic locality, collection date, latitude and longitude, sampler devices, depth and the Cox1 sequence.
