The newest Commonwealth member country, Maldives, has joined Seychelles to launch a joint scientific expedition to investigate unexplored depths of the Indian Ocean.
The research mission, known as ‘First Descent: Midnight Zone’, was officially launched at the Commonwealth headquarters at Marlborough House.
Led by the UK research institute Nekton, the goal is to boost the sustainable governance of Seychelles and Maldivian waters, including the protection of 629,000 km2 of ocean.
It supports the Commonwealth Blue Charter – a shared commitment by member countries to protect the ocean from the effects of climate change, pollution and overfishing.
Minister for Fisheries, Marine Resources and Agriculture of the Maldives, Zaha Waheed, said: “It is vital to comprehensively understand what lies beneath our waters in order for us to be informed enough to take necessary actions towards a healthy and prosperous ocean.
“This mission will, for the first time, show a glimpse of what the deep sea features and the biodiversity it holds. It will also contribute to the wider goal of marine spatial planning and ocean governance.”
A 50-person crew will set sail on 16 March, using the world’s most advanced deep diving submersible, equipped with a suite of research tools including sensor and mapping technology.
The data they collect will help countries define conservation and management priorities and map out marine protected areas. It will also help measure the impact of climate change and human activity in the area.
The expedition will focus on undersea mountains or ‘seamounts’ in the Midnight Zone – depths from 1,000 to 4,000 metres, where biodiversity peaks. This zone holds critical indicators to measure the impact of the climate crisis, fisheries management, heat absorption, acidification, ocean carbon cycle, and plastic, agricultural and industrial pollution.
The mission’s principal scientist Lucy Woodall from the University of Oxford, added: “We find the greatest biomass in the upper few hundred metres of the ocean, but the peak of biodiversity is in the greater depths, in the Midnight Zone, from 1,000 to 4,000 metres. That said, less than 300 of 170,000 known major seamounts found in this zone have been researched to date, and they remain one of the least researched parts of the ocean.”
Nekton is also working with Commonwealth countries to develop the tools, skills, knowledge and networks to sustainably manage the ocean. Seychellois and Maldivian scientists will join the expedition to conduct pioneering research into their national waters. This is supported by training programmes, research grants and fellowships with the University of Oxford.
