One of the most unexplored marine ecosystem on earth, Swatch of No-Ground globally famous for its cetacean – whales, dolphins, porpoises, sea turtles and other rare species – population. A part of it was announced as the country's first Marine Protected Area (MPA) by the Ministry of Environment and Forest in 2014. In March last, a team of 13 Bangladeshi researchers mapped the canyon, while the ongoing expedition is a follow-up to the research. During the latest expedition, it was revealed that the Swatch of No-Ground covers 173,800 hectares area and is one of the 11 deepest canyons in the world. Known as the treasure trove of marine biota, the canyon, formed over 125,000 years ago, holds a special significance in terms of the prospects of the “blue economy” of the country.
