Black Sea oil spill impacting on dolphinarium

A dolphinarium near 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.

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

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

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

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

Authorities initially estimated that 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 sea.
