A multi-phase SPH simulation of oil spill diffusion in seawater currents
In case of oil spills due to disasters, one of the main environmental concerns is the oil trajectory and, consequently, its spatial distribution. In the present study, two-dimensional (2D) smoothed particle hy...

Open AccessEffects of global warming on Mediterranean coral forests
The effects of global warming have been addressed on coral reefs in tropical areas, while it is still unclear how coral forests are reacting, particularly at temperate latitudes. Here we show how mesophotic co...
