Black Sea oil spill impacting on dolphinarium

A dolphinarium near the site of an oil spill off Russia's Black Sea coast said it has been putting down booms to prevent its waters from being contaminated.

The spill occurred over the weekend at the oil terminal in Yuzhnaya Ozereyevka near the port of Novorossiysk.

Russian media said traces of oil were spotted along the scenic Black Sea coast, including Abrau-Dyurso and at the dolphinarium in Bolshoy Utrish, 25 kilometers (15 miles) to the west, where workers urgently put up barriers to protect the mammals.

The spill's oily film was also spotted in the resort city of Anapa, further west down the coast.

However, Russia's state consumer safety agency, Roskomnadzor said in a statement that an analysis of water samples along the Black Sea coast has found that it remained within norms.

Authorities initially estimated that the spill covered only about 200 square meters (2,153 square feet), but Russian scientists said Wednesday after studying satellite images that it actually covered nearly 80 square kilometers (nearly 31 square miles).

WWF Russia has estimated that about 100 metric tons of oil have spilled into the sea.
