Sediments Swirling from the Po Delta, Italy44.9N 12.5E
Sediments spilling from the mouths of the River Po into the Adriatic Sea give the waters off the coast of Italy a greenish tinge. Water currents swirl one plume coming off the easternmost tip of the Po Delta into a spiral form.
The delta, which has five main channels and hundreds of other smaller ones in the province of Rovigo, expands in surface area by about 60 ha per year, due to the eastward movement of the mouths of those channels. Rovigo, therefore, is the only province in Italy whose territory is expanding.
