The Team


Cliff Benson

Founder and Managing Director


Cliff is a naturalist and conservationist, involved in aquatic conservation since he was a founder member of WAYD (the Wildlife Association of the Yorkshire Derwent). The group was concerned with protecting the River Derwent in his native Yorkshire from canalization in the 1970’s. It was during this period he started his long association with local Wildlife Trusts.

He moved to West Wales in 1978 as a partner in Cambrian Bird Holidays helping to establish one of the UK’s first Eco Tourism enterprises. circumstances took him away from Wales but spent several Springs in protecting Red Kite Nests in Mid Wales volunteering with the Tregaron Community Kite Group. It was at this time he first met Iolo Williams, (now a good friend and honorary President of Sea Trust).  He returned with his partner Frederike, shortly afterwards he was involved in organizing a team of volunteers rescuing oiled sea birds during The Sea Empress Oil Disaster.

Consequently, Cliff began to realise our local Pembrokeshire Marine wildlife was under-recorded and set up Sea Trust as the marine section of the Wildlife Trust. In 2013 Sea Trust took over the management of the Ocean Lab on Fishguard Harbour which necessitated leaving the Wildlife Trust and setting up Sea Trust as a not for profit Community Interest Company, operating as financially independent autonomous community project.

When asked what he most enjoys about his work he answers:

I guess it’s finding out about and raising awareness of the incredible but poorly understood wildlife here in Pembrokeshire, literally on our doorstep. From great whales to our enigmatic little porpoises, I just love it when someone sees a Whale, dolphin or a porpoise for the first time with us”

Anna Elliott

Project Development Officer, Coleg y Môr


Anna joined Sea Trust in 2016. She has an MSc in Environmental Biology, Conservation and Resource Management. Her MSc research project involved working with a local company to determine the ecological prospects of harvesting barrel jellyfish for collagen in Carmarthen Bay. This research was published in the ICES International Journal of Marine Science. Since completing her BSc (Hons) in Environmental Science 11 years ago, she has gained diverse work experience in the commercial and government sector. She worked in South Africa as an Environmental Consultant and Environmental Control Officer. Prior to that she worked on social ecology projects at Forest Research in Edinburgh. In her spare time Anna enjoys spending time outdoors with her husband and two daughters.

Lloyd Nelmes

Project Coordinator, Porpoise Photo ID


Lloyd is Sea Trust’s newest member working alongside Holly as Project Coordinator allowing the porpoise photo ID project to expand. Lloyd has a BSc in Marine Biology and is currently working on improving his dive qualifications. Being around the sea so much has unfortunately allowed him to notice the increase in marine plastic pollution so has made it his mission to clean up the Pembrokeshire coast with Surfers Against Sewage organising beach cleans all year round. If he isn’t on the shore looking for our local wildlife he is in the sea surfing or diving with it!


We currently have 2 interns. We are looking for interns from April 2018. If you are interested in our internship programme please contact us.

Gita Matlášková


Gita is from the Czech Republic and is here with the Erasmus+ programme. She is studying for a masters in Ecology. Gita is interested in all marine ecology but she is a keen bird enthusiast.

Alexandra Smith


Alexandra is from London. She has a background working with children with learning difficulties but wants a change of career. She is interested in all of the marine wildlife and loves helping with our aquarium.

Previous interns
Many thanks to all our previous interns. Sea Trust would not be possible without all your hard work. There are too many names to mention everyone but special thanks to our interns over the past 2 years who have helped to get the aquarium up and running again. Laura Rommens, Jens Rasenberg, Fenella Wood, Sophie Crouch, Sophia Ellis, Laura Lemey, Rens Hensgens, Ruben Caballero, Ruben Serrano and Santiago Delgado!!!


We also take final year students who need to collect data for their final year dissertation. In 2017 we hosted Sophia Ellis from Swansea University. We’re happy to say she received a 1st for her project “Spatial and temporal variations in the distribution and abundance of harbour porpoise, Phocoena phocoena, along a fixed transect between Fishguard and Rosslare Harbour“.


Sea Trust’s volunteers make all our work possible, and we are extremely proud of their dedication to the Sea Trust’s work and vision.

Ken Barnett


Ken has been a Sea Trust volunteer for three years. He carries out surveys at Strumble Head most days of the year, and his brilliant porpoise photography has been the driving force behind our new Porpoise Photo ID project, which is stretching the limits of land-based porpoise photographic ID – currently only carried out in a few other locations worldwide.

She took her first WOW (wildlife observer wales) Cetaceans course in 2011, and has since completed the WOW Sea Birds, Seashore Life, Seals and Wildlife Observer Tour Guide courses! Her time with the Sea Trust led to Barbara studying for a Marine Biology Diploma in 2015 as well as becoming a STEM ambassador. Barbara has also been involved with tour guide, educational and aquarium work at the Ocean Lab. She currently represents Sea Trust at conservation meetings at Pendine and Pembrey air weapons ranges, and surveying and recording marine mammals at Cefn Sidan, Pembrey.

Volunteering for Sea Trust has allowed me to meet, work and socialize with people from all walks of life, backgrounds and countries and make some great friends along the way.
