The ocean continues to guard its greatest mysteries. Despite decades of exploration, 93% of Trinidad and Tobago's waters remain virtually uncharted. This vast deep-sea realm, spanning from a few dozen meters to four kilometers down, has never before been systematically explored using modern technology.
This is the setting for the new scientific expedition 'Deep Wonders of Trinidad and Tobago'—a journey not just into the abyss, but to the very frontier of our knowledge about life on Earth.
Over the course of a month, the research vessel R/V Falkor (too) will operate in one of the most poorly understood regions of the Caribbean Sea. Scientists estimate that more than 1,600 species unknown to science could be hidden here, contrasting with the mere 451 deep-sea species currently recorded in the area.
The expedition is being conducted by the international organization SpeSeas, the Schmidt Ocean Institute, the Institute of Marine Affairs, and the University of the West Indies (St. Augustine Campus). This mission holds special significance because it marks the first time that deep-sea research in the region is being led by local scientists from Trinidad and Tobago, headed by marine biologist Dr. Diva Amon.
Researchers will investigate environments that seem to exist outside our conventional worldview: methane seeps, mud volcanoes, underwater canyons, twilight coral reefs, and other deep-sea ecosystems where life follows its own unique laws. It is in these places that organisms never before witnessed by humanity may reside.
Cutting-edge technology will serve as the scientists' primary toolset. The remotely operated vehicle SuBastian will transmit ultra-high-definition video from depths of up to 4,500 meters. Joining it for the first time in the region is the innovative DORIS (Deep Ocean Research and Imaging System), capable of conducting surveys at depths of 6,000 meters while recording imagery alongside environmental data such as temperature, salinity, and water composition.
However, the expedition’s goals extend far beyond the search for new species. Researchers seek to understand how Caribbean deep-sea ecosystems are structured, how they are interconnected, and how they are being impacted by climate change, microplastics, and other human activities.
The project’s transparency adds exceptional value to the mission. All primary dives will be livestreamed, allowing people around the globe to witness discoveries almost as they happen. Science becomes a process that everyone can experience firsthand.
We often assume that the age of great geographical discovery is long over. Yet the ocean reminds us once again that the largest blank spots on the map are not in outer space, but right here beneath the surface of our own planet.
Every new dive has the potential to reveal an unknown species, a unique ecosystem, or a new chapter in the history of life on Earth. Perhaps in the coming weeks, the depths of the Caribbean will yield discoveries that reshape our understanding of just how wondrous the ocean remains.
