She has an MSc in Environmental Management, with her main interests lying in wildlife conservation, human wildlife conflict and understanding the effects of anthropogenic activities on marine wildlife.


Sara is committed to continued professional development, actively participating in training courses and volunteering where possible. The MMOA is important to her as it brings community and support amongst peers and can be a driver of positive change. She would like to see the MMOA continue to work towards better standards for both the MMOs and marine mammals alike, in addition to encouraging implementation of more robust mitigation guidelines using research and the experience of MMOs to guide this.

Diana Antochiw (Secretary)

Diana AntochiwDiana Antochiw is a marine biologist who has been working with marine mammals since 1996. She founded the Yucatan Marine Mammal Stranding Network, the first of its kind in Mexico, and helped train people participating in other stranding response groups.

She served as a MMO on board oceanographic research vessels of the Mexican Navy and later was recruited by Lamont Doherty Earth Observatory as a MMO for marine seismic research. She has advised several organizations working in marine mammal stranding response and marine fauna rescue and research. Later, she helped train some of the first MMOs in Mexico. She works as MMO for the seismic industry worldwide while she still conducts research in marine megafauna in Yucatan.

She is currently a board member and Research Coordinator of the Marine and Coastal Megafauna Research Institute (INMMAR) in Mexico and a member of the Local Committee for Response to Oil Spills, directed by the Mexican Navy.

Carolyn Barton (Stone)

Carolyn Barton (Stone)Following a PhD on barnacles Carolyn spent 5 years with the JNCC's Seabirds at Sea Team, but has spent the last two decades working in MMO-related areas.

She has substantial experience working as an MMO covering seismic surveys, drilling, dredging and pile-driving operations. She has been an accredited MMO trainer since 1996 and has trained over 2500 MMOs. Carolyn has also been involved in the development of mitigation measures and data recording protocols. She has created and analysed JNCC's database of MMO data from UK waters, including analysis of a 16 year dataset to examine the effects of seismic airguns on marine mammals and compliance with the JNCC guidelines.

Carolyn recognises the importance of maintaining professional standards and is pleased to have served on the MMOA committee for eleven years.

Michael Hill

Michael HillMichael graduated with distinction from the University of Glasgow in 2016, with an MSci in Marine and Freshwater Biology. His final submissions studied the impacts of onshore renewables on freshwater ecosystems, and the effects of micro-habitat on intertidal fish assemblages.

Michael works in environmental consultancy, starting as an undergraduate intern in 2014, and now holding the position of Fisheries Consultant, where he works on a range of renewable, infrastructure and network projects. Michael volunteers as a medic for BDMLR and, in addition to marine mammals, maintains a keen interest in all aspects of natural history including ornithology, fish and terrestrial mammals.

Working in consultancy, Michael has had the opportunity to work on various offshore projects as an MMO, and hopes to see increased work opportunities for MMOs through the responsible delivery of a growing offshore renewables sector.

Jon Kenny

Jon KennyJon is a marine biologist and environmental ecologist with over 12 years’ experience in environmental impact assessment, fisheries, and environmental mitigation. He is also an experienced diver with 15 years of recreation and later as a commercial diver and diving instructor.

His work has taken him to Central and South America, Africa, Asia, Europe and the Antarctic. Jon has led dive and survey teams, managed a marine protected area (MPA) for a government fisheries advisory group, been project coordinator for environmental impact assessments (EIA), and ran the whale shark education and turtle protection programs among other environmental projects around the world.

Jon's most challenging work was in fisheries auditing vessel safety and catch records according to strict and complex regulations in sometimes extreme conditions. He currently lives in Sonora Mexico on the coast of the Gulf of Mexico.

Ashley Noseworthy

Ashley NoseworthyAshley is the CEO and Founder of Edgewise Environmental Ltd. She holds a B.Sc in Biology from Memorial University of Newfoundland (Canada) and a M.Sc in International Marine Environmental Consultancy from Newcastle University (UK), where she completed her thesis in the area of Harbour Porpoise acoustics.

She has over 12 years experience working and volunteering in the areas of marine mammal husbandry, marine mammal physiology and cognition. 

Ashley is also an experienced aviation, offshore and sea survival instructor. Her primary professional interests include marine mitigation policy and anthropogenic effects on marine mammal populations. She is an advocate for collaboration between industry, academia and government; through which she believes discourse between all three could result in more meaningful change and positive impacts to global marine mammal protection.

Gary Robinson

Gary RobinsonGary Robinson is co-director of the UK based marine environmental consultancy Ocean Ecology Limited and an experienced marine mammal consultant, observer and acoustic monitoring operator in relation to the offshore renewables and seismic industries.

Gary has in excess of 8 years’ experience of designing, managing and undertaking a wide range of marine mammal mitigation and monitoring programmes worldwide and has been responsible for project managing a number of marine mammal mitigation programmes for some of the largest offshore wind farm developments in the world. Gary also provides marine mammal consultancy to regulatory bodies and is currently reporting the findings of his latest project, on behalf of Natural Resources Wales (NRW), for which he directed the first full census of grey seal pups in North Wales undertaken since 2004.

Gary’s keynote project in the seismic industry was his role as lead marine mammal consultant on behalf of Sakhalin Energy Investment Company (SEIC) and Shell to fulfil a complex offshore marine mammal mitigation programme developed between SEIC and the ICUN-established Western Gray Whale Advisory Panel (WGWAP).

Patrick Lyne

Patrick LynePatrick Lyne has worked in mitigation for 11 years and been involved with the MMOA committee for seven years.

Patrick is committed to improving standards of mitigation at a regulatory and MMO (and PAM) level. Industry contraction has affected everyone and perhaps the standards in mitigation more so. However Patrick hopes things will change and would like to see a shutdown employed in all mitigation procedures where an injurious level of sound is used.

He would also like to see experience as part of requirements in future work, such that one MMO and PAM operator on the mitigation team has some credible expertise.
