Coastal upwelling off Peru and Mauritania inferred from helium isotope disequilibrium

Upwelling is an important process, bringing gases and nutrients into the ocean mixed layer. The upwelling velocities, however, are too small to be measured directly. Here we use the surface disequilibrium of the <sup>3</sup>He / <sup>4</sup>He ratio measured in two coastal up...
