Deepex Carib

Explore Caribbean deep seas to lay the foundations for locally driven, science‑based protection

The Deepex Carib project

CONTEXT AND MAIN ISSUES

The waters of Trinidad and Tobago encompass unique deep‑sea ecosystems ranging from the mesophotic zone to abyssal depths. These habitats represent more than 93% of the country’s waters and include key environments such as deep reefs, coral and sponge communities, and natural methane seeps hosting specialised biodiversity.

Yet less than 0.001% of these mesophotic and deep‑sea areas have been explored to date. This lack of knowledge contrasts sharply with increasing human pressures: seabed resource extraction, pollution, fishing, and climate‑change impacts.

Without baseline scientific data, identifying vulnerable ecosystems, understanding ecological connectivity, or designing effective marine protected areas remains extremely difficult. Exploring the Caribbean deep sea is therefore a critical prerequisite for protection, especially as Trinidad and Tobago seeks to strengthen marine protected area planning.

GOALS

To scientifically explore, document and sample the unique species and ecosystems of Trinidad and Tobago and the adjacent High Seas, down to 4,500 metres depth, in order to provide essential scientific data for ocean conservation and sustainable management.

METHOD

The project builds on an exceptional scientific opportunity: a 30‑day oceanographic expedition aboard the research vessel RV Falkor (too), operated by the Schmidt Ocean Institute, scheduled for July 2026.

Using a remotely operated vehicle (ROV) capable of diving to –4,500 m, researchers will conduct scientific exploration across several priority sites.

Deep‑sea ecosystems will be documented through imagery, sonar mapping and biological sampling, enabling the characterisation of biodiversity, sensitive habitats and human impacts.

These data will form the scientific basis for analysing deep‑sea connectivity, assessing conservation status, and informing future ocean management decisions at national and regional scales.

HOW IS THIS PROJECT INNOVATIVE?

Deep Wonders of Trinidad and Tobago and the adjacent High Seas is one of the very first expeditions dedicated to the uncovering the deep waters of Trinidad and Tobago, an area that remains largely unexplored and therefore rich in discovery potential. The project combines state‑of‑the‑art technologies (deep‑sea ROVs, sonar mapping, as well as testing of a new low-cost deep-sea imaging tool: the DORIS lander, and of a shipboard cryopreservation. This project uses a multidisciplinary approach. It also stands out for its strong local and social dimension: led by Caribbean scientists, the mission strengthens local capacities and ensures that data and samples directly benefit institutions in Trinidad and Tobago.

By generating essential baseline data, DEEPEX CARIB helps lay the foundations for durable, science‑based ocean stewardship in a region still largely absent from global deep‑sea conversations.
