OTERO-DIAZ, Luis et al. Three-dimensional oil spill transport and dispersion at sea by an event of blowout. Dyna rev.fac.nac.minas [online]. 2014, vol.81, n.186, pp.42-50. ISSN 0012-7353.  http://dx.doi.org/10.15446/dyna.v81n186.37951.

The simulated droplet trajectories of the 3-D model at the Caribbean platform showed that droplets with a diameter of 50mmformed a distinct subsurface plume, which was transported horizontally and could remain below the surface. This plume could have a very restricted area of impact because the dispersion is only controlled by the ocean currents which, at 1000 m depth, have a low intensity and are quite turbulent. In this case, the formed plume stayed trapped at 1000 m depth, not posing a risk to the Caribbean Coast. In contrast, droplets with diameters of 250mm, 1 and 10mm rose rapidly to the surface, even with different velocities (6, 10, 20 ms-1).
