Scientists to explore Indian Ocean depths

BREMEVERHAVEN: Scientists prepared on Thursday to embark on an unprecedented, years-long mission to explore the Indian Ocean and document changes taking place beneath the waves that could affect billions of people in the surrounding region over the coming decades.

The ambitious expedition will delve into one of the last major unexplored frontiers on the planet, a vast body of water that’s already feeling the effects of global warming. Understanding the Indian Ocean’s ecosystem is important not just for the species that live in it, but also for an estimated 2.5 billion people at home in the region from East Africa, the Arabian peninsula, South and Southeast Asia.

The Nekton Mission, supported by over 40 organisations, will conduct further dives in other parts of the Indian Ocean over three years. The research will contribute to a summit on the state of the Indian Ocean planned for late 2021.

The Ocean Zephyr is preparing to leave Bremerhaven, Germany, on the first leg of trip. Researchers will spend seven weeks surveying underwater life, map the sea floor and drop sensors to depths of up to 2,000 metres (6,560 feet) in the seas around the Seychelles.

Little is known about the watery world below depths of 30 metres (100 feet), which scientists from Britain and the Seychelles will be exploring with two crewed submarines and a remotely operated submersible in March and April.

Ronny Jumeau, the Seychelles’ ambassador to the United Nations, said such research is vital to helping the island nation understand its vast ocean territory.

While the country’s 115 islands together add up to just 455 square kilometres of land about the same as San Antonio, Texas its exclusive economic zone stretches to 1.4 million square kilometres of sea, an area almost the size of Alaska.

Jumeau said the Seychelles aims to become a leader in the development of a “blue economy” that draws on the resources of the ocean. The archipelago relies on fishing and tourism, but has lately also been exploring the possibility of extracting oil and gas from beneath the sea floor.
