"The sand patterns around the Wheeler Island are changing. Due to erosion, some 300 metre of sand area have submerged sometime and some sand is showing up in other part of the island," DRDO's Chief Controller (R&D) Avinash Chander said.
Since Wheeler Island is technically a "sand bar" with a size of approximately one sq Km in the Bay of Bengal and not a rock formation, water currents result in the change in sand patterns, he said.
Though DRDO has already planted over two lakh tree saplings including casuarina and taken other steps to control the situation, he said, adding that we have requested NIOT to send a team of experts to realise the situation.
Wheeler Island, located some 10 Km off Chandipur in Odisha, is the only missile test firing range in the country for defence purposes.
Chander earlier delivered the keynote address for the 'Technology Day Celebrations' at the National Institute of Ocean Technology (NIOT) here.
Replying to another query, he said the country is designing a solar-powered Unmanned Aerial Vehicle at its lab in Bangalore, which aimed at flying more than 36 hours with solar power.
