Being pushed by high tide, the spilled oil spread to the coast. Villagers claimed that they had seen carcasses of adult turtles along the coast after the sea water had been contaminated. Around 155, 000 of the rare Olive Ridleys had nested along the coastline in March while the mass hatching of eggs, which continued for a week, ended last week.

　　“The authorities cleaned only 2 km—3 km stretch of the beach. Many eggs were damaged due to the effect of oil deposits. Moreover, many baby turtles failed to move out of the nest as the soil also got harder，” Sahu, who along with villagers of Purunabandha has been working in the turtle conservation programme in the last 16 years, said.

　　Turtle expert Kartik Shanker also raised similar concerns. “The oil spill will have an effect on the mortality rate of the hatchings. But scientifically, it is not possible to arrive at a mortality figure for it，” Shanker, a professor at the Indian Institute of Science, Bengaluru, said.

　　Marine scientist Bijay Kumar Sahu said there was an immediate need for a detailed multi­discipline faculty study on the long­term impact of the oil spill on the marine environment. State forest and wildlife officials, however, refuted (反驳) the claims. “The oil spill has had no effect on the hatching process. Oil was cleaned from the beach a long time ago and the issue is now a closed chapter，” the state's Chief Conservator of Forests (Wildlife), Srivastava said.
