Short summary
Helium isotopes are a powerful tool in Earth sciences. We present the first simulation of the terrigenic helium isotope distribution in the whole Mediterranean Sea, using a high-resolution model (NEMO-MED12). In addition to providing constraints on helium isotope degassing fluxes in the Mediterranean, our simulations provide information on the ventilation of the deep Mediterranean waters, which are useful for assessing NEMO-MED12 performance.
