One of my most special research papers has been published! It is the first of my papers to focus on the deep sea around my home country, Trinidad and Tobago. It also looks to stewardship and conservation of our seas, it is open access so that is available to increase readership, and it is a collaboration between an awesome group of female marine scientists! Check out the below synopsis as well as the paper for more information!

83 deep-sea species, with several new to science, found at cold seeps in areas vulnerable to oil and gas exploitation.

For the first time, local marine biologists (Drs. Diva Amon and Judith Gobin) have investigated the deep sea off Trinidad and Tobago, discovering two new cold seeps hosting unique communities of animals. The discovery, made almost a mile deep, reveals important information about the biodiversity of the deep ocean around Trinidad and Tobago. Additionally, it enables comparisons with similar habitats elsewhere in the Caribbean.

“These communities are absolutely amazing: hundreds of thousands of 8-inch deep-sea mussels, as well as 3-foot tubeworms, crabs, shrimp, snails and fishes were found living at the seeps between 1000 and 1650 metres depth” says Dr. Amon, a postdoctoral researcher. “The information gained from this study is crucial to understanding Trinidad and Tobago’s almost entirely unknown deep ocean, especially given the increasing oil and natural gas exploration and exploitation”.

Amon is lead author of a research paper reporting the work this week in the scientific journal Frontiers in Marine Science, in collaboration with Dr. Judith Gobin of the Department of Life Sciences at The University of the West Indies, and colleagues from Duke University, Scripps Institution of Oceanography, University of Southampton, and the Ocean Exploration Trust.

Eighty-three species of animals were recorded from extensive seep communities at four sites, two previously known and two new. The newly discovered seep sites have been named after two Trinbagonian female folklore characters: La Diablesse and Mama D’Leau. One of the most remarkable discoveries was that during the surveys in this area, 85 further sites were detected off the east coast of Trinidad.

Cold seeps are areas where fluids rich in hydrogen sulfide and methane leak from the seafloor, similar to hydrothermal vents. This fluid provides the energy to sustain large communities of life in the harsh conditions that exist in the deep sea (no light, approximately 4°C temperature and more than 100 atmospheres of pressure). At cold seeps, bacteria create food via chemosynthesis in the absence of light, using the chemicals in the fluid, in a similar way to plants, which use sunlight for photosynthesis. These microbes use the oxygen in seawater to oxidize the chemicals present in the seep fluids and form the basis of the food chain at these environments. These bacteria can form thick white mats or live inside many of the animals at these seep sites including the mussels, tubeworms and clams providing food directly. Other organisms such as snails and shrimp seen at the new sites may feed directly on the bacterial mats, in turn providing food for eelpout fish, crabs and other predators. As a result, cold seeps are oases of life, patchy areas of huge abundances of unique endemic animals.

“These cold-seep sites and the associated fauna, were an exciting find that I can now use as real examples of our own deep-sea, for my students” says Dr. Gobin. “I am extremely pleased to be engaging in this cutting-edge exploration and science in Trinidad and Tobago waters” says Gobin.

Species of a purple octopus, a white sponge and an orange anemone were also discovered and being new to science, do not yet have names. Many of the animals are also poorly understood, such as a species of eelpout fish that lives amongst the mussels, Pachycara caribbaeum, that is known from only one other small site in the Cayman Trench.

Unfortunately, these newly discovered areas are already under threat. These cold seeps, potentially Ecologically and Biologically Significant Areas (EBSAs), will likely be irreparably damaged by drilling and associated oil and gas activities. Scientific research in this area is struggling to keep up with such commercial activities and without targeted actions, these species and their habitats may be lost before they are even studied. The authors list a number of recommendations for the stewardship and conservation of these deep-sea habitats.

Drs. Amon and Gobin hope that this is just the beginning for deep-sea science in Trinidad and Tobago. “Not only are we blessed with an amazing diversity of life on land and in shallow waters here in Trinidad and Tobago’,” says Amon, “but also down in the deep sea. Only when we understand what exactly exists in the depths of our waters will we be able to protect and manage this biodiversity”.

Drs. Amon and Gobin are continuing to collaborate on several other deep-sea projects focused on the Caribbean, including the naming and description of the new species. Dr. Gobin and NIHERST are presently working on an educational deep-sea DVD series and are actively seeking funding for the series, which is almost completed.

The findings presented in this study were as a result of a deep-sea exploratory mission on board the Exploration Vessel (E/V) Nautilus in 2014 that Drs. Amon and Gobin were selected to join. The E/V Nautilus is a 64-meter research vessel operated the Ocean Exploration Trust. The ship carries with it two Remotely Operated Vehicles (ROVs), Hercules and Argus, which explore the seafloor and can be viewed in real time online at

I have been terrible with keeping my website up to date so this post summarises all of my news from July 2016 to May 2017. It covers papers published, workshops attended, outreach done and some very big career changes.


Let’s get the big stuff out of the way first!

After three great years in the Smith Lab at the University of Hawaii in Manoa, I decided that it was time to move on. So in November 2016, I packed my bags and headed back to my family home in Trinidad and Tobago to spend some much needed down time with my mum and dogs.

In December 2016, I was hired as consultant by Pew Environment to help coauthor the nomination of National Marine Sanctuary Designation For The Marianas Trench Marine National Monument. You can find that document here.

Then in February 2016, I got the FANTASTIC news that I had been offered a Marie Sklodowska-Curie Individual Fellowship! So from March 2018, I will undertake two years of my own research on deep-sea mining in Dr. Adrian Glover’s lab at The Natural History Museum, London.

In October 2016, I was fortunate to attend the OBIS-INDEEP training workshop at the UNESCO-IOC project office for IODE in Oostende, Belgium. The meeting brought together deep-sea biologists and data managers in an effort to build an international alliance with a common vision to provide open access to deep-sea biodiversity data. This will hopefully enhance our understanding of the deep-ocean ecosystem in order to better inform ocean governance and management. You can read more about it here.

In April and May 2017, I participated in a pilot study by NOAA’s Cooperative Institute for Ocean Exploration, Research & Technology (CIOERT) as a biology expert for the Okeanos Explorer expedition to the Western Pacific between Pago Pago (American Samoa) and Honolulu via telepresence at the Harbor Branch Oceanographic Institute Exploration Command Center.

Science Communication and Outreach

In July 2016, I represented NOAA’s Office of Ocean Exploration and Research in Guam and the Commonwealth of the Northern Marianas Islands to present the findings of the three-leg expedition by the NOAA Ship Okeanos Explorer earlier that year. You can read about that here.

Now that I am in Trinidad, one of my goals is to increase the public’s awareness of the deep ocean. I intend on doing this via a series of talks, blog posts and newspaper articles. The first of those was a talk at the Trinidad and Tobago Field Naturalist Club on the deep sea around Trinidad and Tobago in February 2017, which you can watch below. Stay tuned for more!
