Sitting alongside the Tembladora dock currently, waiting for departure, is the R/V Falkor (too). Inside, anticipation is building for an expedition that promises to reveal one of Trinidad and Tobago’s greatest mysteries, the deep sea beneath its own waters.
Guardian Media was invited aboard for a brief tour before the month-long scientific mission gets underway. Led by a team of T&T researchers aboard one of the world’s most advanced ocean research vessels, the expedition will soon travel across Tobago’s east coast, documenting ecosystems and marine life that have never been observed.
For many readers, the deep ocean may seem remote, but it makes up the largest part of the country’s marine territory.
“There is so much that Trinbagonians do not know about this amazing ecosystem that is the majority of our country,” Chief Scientist Dr Diva Amon told Guardian Media during the tour.
“Trinidad and Tobago is 70 per cent deep sea and actually more than 93 per cent of that is below scuba depths and that means we do not ... we have not been able to access that from a scientific perspective. There is so much left to discover.”
The journey will begin in waters as shallow as 60 metres before descending thousands of metres into complete darkness, where immense pressure and near-freezing temperatures create an environment unlike anywhere on land.
Yet, scientists say it is anything but lifeless.
“One of the biggest misconceptions about the deep sea, I think, is that it is empty, lifeless,” Dr Amon said.
“That could not be further from the truth. This is an incredible place, home to hundreds of thousands of species globally. It is critical for the functioning of the planet in that it supports fisheries, it regulates our climate, it is home to so many different species that we use in some way and there is just so much that we still don’t know.”
Co-principal Investigator, Dr La Daana Kanhai, of The University of the West Indies, says those hidden ecosystems stretch far beyond the coastline most people know.
“As you move east of Trinidad and as you move east of Tobago, even north of Tobago, that depth descends to in excess of 3,000 metres, and the thing is life proliferates throughout the water column in all environmental compartments,” she said.
“I think that’s something that maybe many Trinbagonians are unaware of, that in every drop of water there’s life.”
The vessel’s remotely operated vehicle, SuBastian, will descend to depths of up to 4,500 metres, transmitting live high-definition images from the seabed while collecting samples and mapping the ocean floor. Every dive will also be livestreamed, allowing members of the public to watch discoveries unfold in real time.
While the expedition is expected to uncover new species and previously unseen habitats, the research also has practical importance. Scientists hope the information gathered will guide future decisions about managing offshore ecosystems and identifying areas that deserve protection.
“We are exploring so that we can better steward,” Amon said.
“By gathering the scientific data, by answering these scientific questions that nobody has answered before, we can then use that to inform the decisions that we are making about how we use these parts of the planet.”
That knowledge is becoming increasingly important as climate change, pollution and other human activities reshape the oceans. Scientists say the deep sea plays a vital role in regulating the Earth’s climate, storing carbon and supporting fisheries that coastal communities depend upon.
“We know our planet is changing, and the deep sea is absolutely not immune from that,” Amon said.
“Pollution, climate change, there may be impacts from oil and gas extraction and much, much more, so this is really a place that is very fragile, and we need to do all that we can to learn as much as we can about it.”
For Amon, however, the voyage carries a meaning that extends beyond science.
Years ago, she sailed from Port-of-Spain as a young researcher, joining a British-led deep-sea expedition. This time, she returns to the same waters leading a predominantly T&T scientific team.
“Here we are 16 years later. Instead of there being a British team on board with one scientist, we have a primarily Trinidadian, Trinbagonian team on board and we are leading the science and now, I am in a leadership position,” she said.
“It really feels very, very full circle, and I hope this will be a dream come true and a very special moment.”
By the time the Falkor (too) returns on July 28, therefore, the country’s deepest waters may no longer be its greatest mystery.
