Ricardo Sagarminaga van Buiten

Research Associate

Since 1984 Ricardo Sagarminaga van Buiten, skipper and marine research program coordinator, has combined his passion for sailing and building tall ships with his lifelong dedication to the conservation of marine biodiversity.  Ric’s work has focused on developing marine apex predators monitoring surveys, designing and managing protected marine areas programs, and the conservation of endangered species and the sustainability of fisheries worldwide.

He specialises in coordinating international scale research and conservation programs and creating innovative technological measures to mitigate the risks to marine life linked to the fishing, defense, energy, transport and tourism industries.

After working with international environmental organisations, public administrations and academia, and becoming member of several scientific committees, he has created his own multidisciplinary approach to provide practical solutions for biodiversity conservation. Among his preferred formulas, Ric has used active education, citizen science and public volunteering as a tool for linking conservation strategies with the general public.

After founding and running the Spanish Cetacean Society, he co-founded ALNITAK Marine Research and Education center (www.alnitak.info) to generate novel environmental outreach strategies and forge a new tradition of cooperation between key international outfits. The success of the programs coordinated by Ric is largely due to having established schemes based on a positive and active involvement of all stakeholders in the search of win – win solutions. Following on this philosophy he later co-founded KAI Marine Services (www.kaiexpeditions.com) to provide full technical and scientific consultancy to policy makers aimed at making economic growth and biodiversity conservation compatible.

In 2014, Ric was elected as ASHOKA social entrepreneur fellow for his work in the Mediterranean, Africa and Latin America.

Ana Tejedor

Research Associate

Ana Tejedor is a founder partner of KAI Marine Services. Although specialised in marine management and international negotiation, as sailor and marine expedition coordinator, Ana approaches the world of policy with the perspective of those who are out at sea.

As a Senior Advisor of the Ministry of Agriculture, Food and Environment of the Spanish Government she has provided support for the monitoring and implementation of the main Multilateral Environmental Agreements for the protection of the marine environment in Spain since 2005. The main tasks include developing public policies for the conservation of marine biodiversity and representing the Spanish delegation at the main forums on conservation and sustainable use of the marine environment  (marine groups of the General Assembly of the United Nations, Convention on Biological Diversity,  OSPAR Convention, Barcelona Convention, Migratory Species Convention, Environmental Protection Committee of the International Maritime Organization, European Commission Working Groups).

However, her comfort zone is not only in the arena of international policy negotiation and the integration of its outcome in national levels. In 2009 she created KAI Marine, a “think tank” of international interdisciplinary experts with which she has worked in projects in Europe, Africa and the Americas, in a wide range of environments, often in extreme living conditions both at sea and on land.

Ana won the European Entrepreneur Environmental Award for the development of the KAI Marine Expedition initiative and its Marine Science Programme in November 2012.

Bruno Claro

Research Associate

Bruno Claro holds a Master Degree in marine biology, with specialisation in Marine Ecology and Conservation, and a Post-graduation Degree in Advanced Geographic Information Systems, at University of Algarve.

As a Marine Ecologist and with a desire to diversify his skills, he has participated in a wide range of projects in the last 10 years. He studied the ecosystem metabolism of seagrass meadows in the south of Portugal, the spatial ecology of kelp forests in the Iberian Peninsula, was co-creator of an underwater video technique that improves surveys of fish assemblages, established a socio-economic profile for dolphin watching tourists in Portugal, and participated in several cetacean surveys in Portugal and the Mediterranean Sea.

Bruno´s collaboration with OceanCare is mainly focused on the analysis of the impact of main environmental and anthropogenic drivers on the distribution of cetaceans in the Mediterranean Sea.

Joanna Toole

Dr. Claire Petros, BA, BVSc, MRCVS

Marine Turtle Rescue Expert and Veterinary

As a biologist and a veterinarian, Claire has always had a passion for nature and has known from a young age that she had wanted to work with wildlife. After completing her undergraduate course in Biological Sciences at Oxford University she went on to complete her veterinary training at Bristol University with the Bristol Zoological Society Prize for Zoological Medicine.

During her time in Oxford Claire specialised in marine ecology, and undertook her final year dissertation studying coral bleaching in the Wakatobi National Park, Indonesia. It was during this time that she developed her love of diving, which inspired her desire to work closely with protecting marine life.

Whilst at Bristol Claire spent her final year elective in North Carolina State University (NCSU), she joined the exotic and Turtle Rescue team. During her time in NCSU, Claire witnessed a cataract surgery on a Loggerhead sea turtle! It was an invaluable experience that led to a deeper fascination in turtle medicine. After graduation Claire spent some time in Grenada working as a research assistant for the Wider Caribbean Sea Turtle Conservation Network. It was here that her ambition to combine being a ‘sea turtle vet’ and marine wildlife conservationist began.

In November 2016 Claire joined the Olive Ridley Project and moved to the Maldives to open a Marine Turtle Rescue Centre for ghost gear entangled sea turtles, the first veterinary clinic in the country. Every day Claire would swim in the sea or paddle board around the island and would often encounter turtles, sharks and rays, sometimes even pods of dolphins! Having spent some time working as a small animal vet in London, she is now focussed full time on pursuing turtle conservation work for the Olive Ridley Project. She is also traveling to turtle rescue centres around the world to learn more about how best to medically treat and rehabilitate sea turtles and with the help and support of OceanCare plans to begin a PhD investigating turtle medical welfare at rescue centres in 2019.

Mariel Murazzi

Research Associate

Maria Elvira (Mariel) Murazzi holds a Master Degree in Marine Biology and a Bachelor Degree in Environmental Science at the University of Pisa. Her background has focused on natural resources sustainable management. She contributed to the collection and analysis of technical Northwest Atlantic fisheries data with NAFO (Canada) and she worked with legal aspects of fisheries international legislation at the Council of the European Union (Belgium). She has collaborated with non-profit associations based in different countries (Italy and Cape Verde), aimed at marine mammal and sea turtle conservation.

During her working experiences she has been involved in patrolling beaches, collecting samples, conducting marine surveys, raising awareness about plastic pollution throughout social networks updating, taking part in specific events and teaching activities on cetaceans and climate change topics in primary and secondary schools.

Mariel’s collaboration with OceanCare is mainly focused on the analysis of fishery activities in the Mediterranean Sea, encompassing different topics through a bibliographic research and an interview-based approach. Moreover, Mariel is involved in the implementation of a school programme on plastic pollution.
