Tracking the Movements of Montserrat’s Marine Turtles

Authors – Dr Nicola Weber (Project Leader) and Jack Wiggins (Graduate Research Assistant)

In 2019, a team of researchers from the University of Exeter, Government of Montserrat and Marine Conservation Society were awarded a Darwin Initiative grant to create and implement a Marine Turtle Action Plan on the UK Overseas Territory of Montserrat. The global pandemic delayed a number of the outputs, but we are now excited to bring you our first update from the field!

Lead researchers Dr Sam Weber and Graduate Research Assistant Jack Wiggins from the University of Exeter arrived in Montserrat in June to work alongside staff from the Government of Montserrat and members of the Marine Conservation Society during the turtle nesting season. The project funded by Darwin Initiative will collate both social and biological data to help conserve and manage marine turtle populations around Montserrat. The island supports regionally important populations of green and hawksbill turtles and also gets occasional visits from loggerhead and leatherback turtles.

Graduate Research Assistant, Jack Wiggins provides an update from the island:

Arrival in Montserrat

“It’s nearly over a month since we arrived in Montserrat, and what a month it has been. Twenty minutes after departing Antigua in a tiny six-seater aircraft we arrived in Montserrat and were picked up by Montserrat’s Chief Fisheries Officer, Alwyn Ponteen, and taken to our quarantine villa. From here, we looked over the calm, clear and turquoise waters of Isles Bay – a key mating and nesting site for green sea turtles. We would sit on the balcony, binoculars glued to our faces looking out over the bay watching mating turtles, pelicans diving bombing into the water for food and frigate birds tracking shoals of bait fish further offshore itching to get out and explore the island. After five days of mandatory quarantine and receiving our negative PCR test results we were free to explore “The Emerald Isle of the Caribbean”. On the first day, our host, Chief Fisheries Officer at the Government of Montserrat, Mr Alwyn Ponteen, took us on an island tour where we visited a dozen of the islands’ turtle nesting beaches and tried out some of the local delicacies Montserrat has to offer. The next day we would start our night-time beach surveys with local legend Mr John Jeffers who has been monitoring turtle nesting activities in Montserrat for over 30 years.”

Night-time nesting surveys

“Over the past few weeks, we have been conducting night-time nesting surveys to help understand how many individuals are nesting along the coast of Montserrat. To do this, any nesting female turtles we have encountered laying, we have inserted a PIT tag – a small microchip like those used for cats and dogs – into the right shoulder of the turtle and also attached two flipper tags. Each tag has a unique number so if a researcher, fisher or member of the public encounters a tagged turtle in the future (be it on Montserrat or further afield) and can record the tag number we will know exactly which turtle was encountered and where. Tagging nesting females can help us to understand how many adult females there are in a population which can also help us to keep track of whether the population is growing or shrinking over time.”

Jack and Sam prepare the satellite telemetry devices ready for deployment.

The research grant has funded 10 satellite telemetry devices for the researchers to attach to adult female turtles nesting on Montserrat’s beaches. This state of the art technology allows us to gain an understanding of the movements of these turtles both around Montserrat during the nesting season and then during their migration back to their feeding grounds. Identifying patterns of space use provides the evidence base needed for managing and protecting important marine areas, for example by regulating boat traffic and fishing activity in areas where turtles are congregating or mating around during the nesting season. Only one turtle from Montserrat has previously been tracked with a satellite telemetry device so there is much excitement around these recent deployments.

On average, female green and hawksbill turtles will reproduce every 2-3 years and lay over 3 clutches of eggs within a single nesting season. Each clutch can contain between 100-200 eggs and can take between 45- 60 days to incubate. After a female has finished laying for the season, she will migrate back to her foraging grounds where she will remain for 2-3 years until she has built up sufficient energy reserves to reproduce again and repeat the cycle.

The local team, Turtle Project Officer Mr John Jeffers, Chief Fisheries Officer Mr Alwyn Ponteen, Data Collector Mr Gerard Cassell, with female turtle post-satellite tag attachment.

The University of Exeter and Government of Montserrat field team managed to deploy all ten of the satellite transmitters within 2 weeks, which involved many long nights spent waiting on the beaches until females had finished laying and covering their eggs. The turtle was held in a pen while the device was attached to the back of her carapace (shell) using epoxy resin glue, as you can see in the photos. When the turtle comes to the surface to breathe, this device will send a message to a satellite containing data that can be used to determine the location of the turtle. Excitingly, this can be viewed online in real-time here.

The accuracy of raw locations received from the satellite-based location system can vary depending on the number of messages received from the transmitter, environmental conditions, and the relative positions of the transmitter and satellites. That is why when the turtles are close to shore they can appear to be located on land, but, other than when they are nesting, they definitely are not! Once all of the data have been collected, a range of analytical tools and filters are used to process these locations and produce a ‘clean’ map; but it is very exciting being able to get an idea of their locations in real-time. At the time of writing this blog post, one turtle (Laynakiki) has begun her migration and has passed close by Guadeloupe and Dominica! These tracks will provide us with a fascinating insight into the secret lives of these turtles once they have left Montserrat’s shores.

What’s next?

Jack will remain on island, based with the local Government of Montserrat team until the end of this turtle nesting season in October. The team is continuing with some night-time surveys and tagging nesting females with flipper and PIT tags if encountered, but will mainly be focusing on conducting day-time beach counts, which is the most efficient method for estimating the nesting population size. During the mornings, Jack alongside local Project Officers, Data Collectors and Youth Trainees will be patrolling the nesting beaches to count how many nesting activities occurred the night before and to take GPS locations of any nests laid. Taking GPS locations of nests helps us to identify nesting hotspots around Montserrat and better understand which beaches are key nesting sites that should be monitored more frequently. The on-island team will also be monitoring nest productivity – counting how many turtles emerge from the nests both routinely in the hatchery and opportunistically on the nesting beaches.

All of these different aspects of biological research will inform the Marine Turtle Action Plan for Montserrat which will be written after another full season of data collection next year. This is also being informed by knowledge and views of the local community through project partners – the social science team at the Marine Conservation Society. You can read more about this at their blog.

Juntos podemos? Promover ações para a conservação marinha

Autora – Dr Ana Nuno

Uma pequena ilha remota e pouco conhecida situada no Golfo da Guiné, ao largo da costa da África Central, Príncipe (São Tomé e Príncipe) e a sua população dependem fortemente da pesca artesanal. Quando as comunidades piscatórias da ilha nos dizem que têm de viajar mais longe, passar mais tempo no mar e aumentar a quantidade de equipamento de pesca para obter quantidades semelhantes de peixe que costumavam capturar perto da costa há alguns anos, isto soa muito familiar. Estes problemas são sentidos em muitas zonas costeiras por todo o mundo e podem ser particularmente graves em pequenos estados insulares em desenvolvimento, onde os recursos para a gestão são escassos e as pessoas geralmente têm acesso limitado a outras oportunidades.

Uma comunidade piscatória no Príncipe / Dário Pequeno Paraíso

As comunidades piscatórias são cruciais na abordagem de questões de conservação em todo o mundo. A participação das partes interessadas e a co-gestão das pescas têm sido reconhecidas como abordagens-chave, particularmente quando a execução é um desafio devido à capacidade limitada do Estado. Mas como podemos promover ações individuais e apoiar medidas que melhorem os ecossistemas marinhos? Alguns poderão dizer que precisamos de empoderar as partes interessadas. O empoderamento tornou-se um conceito popular em conservação mas, embora bem intencionado, é muitas vezes utilizado como uma palavra da moda com alegações pouco claras. Como podemos avançar para além desta palavra da moda em conservação?

Centrando-se na conservação marinha e pesca artesanal no Príncipe, o nosso novo artigo científico publicado na revista Conservation Letters identifica os principais determinantes do empoderamento psicológico para a conservação e explora as possíveis implicações para a gestão de recursos. Feito como parte de um projeto financiado pela Darwin Initiative e em parceria com a Fundação Príncipe (uma ONG baseada na ilha), esta investigação incorporou discussões de grupos focais e questionários a agregados familiares (869 pessoas entrevistadas numa ilha com cerca de 8000 residentes!). Recolhemos informações sobre, por exemplo, características individuais e do agregado familiar; utilização de recursos naturais; perceções sobre possíveis intervenções; e múltiplos componentes de empoderamento (por exemplo, governação, liberdade de escolha & ação, participação, controlo e colaboração).

Questionários no Príncipe / Litoney Matos

Constatámos que era mais provável as pessoas acreditarem que poderiam pessoalmente fazer uma diferença na proteção do ambiente marinho na ilha se também: sentissem que a aplicação das leis pelo estado estava a desempenhar um papel ativo, tinham níveis mais elevados de liberdade de escolha e ação individual, e acreditavam que as suas comunidades poderiam, coletivamente, melhorar os resultados. Os entrevistados que responderam “não sei” sobre a atual condição do ambiente marinho na ilha foram menos propensos a acreditar que poderiam fazer a diferença do que aqueles que acreditaram que as condições do ambiente marinho permaneceram as mesmas, piores ou melhores do que antes.

Considerando potenciais intervenções, as pessoas que consideram ter níveis mais elevados de influência sobre a conservação marinha eram as mais propensas a recomendar medidas específicas (por exemplo, criação de áreas de pesca interdita). Isto sugere ligações entre empoderamento e a aceitação social de potenciais intervenções específicas.

Porque é que isto importa? O envolvimento em projetos de conservação pode ser influenciado pela crença nas capacidades individuais para alcançar a mudança. Havendo agora um novo projecto na ilha liderado pela FFI e destinado a estabelecer a primeira rede de áreas marinhas protegidas no país, esta informação é crucial para compreender como envolver significativamente as comunidades locais e outras partes interessadas. Isto é essencial para identificar visões comuns e trabalhar em colaboração para as alcançar. Como esta investigação demonstra, isto pode exigir a abordagem de várias questões diferentes mas que andam de mãos dadas (por exemplo, acesso a oportunidades, sensibilização sobre as condições dos ecossistemas marinhos e reforço da aplicação da lei), para que as pessoas acreditem que a sua contribuição pode realmente fazer a diferença. Embora o envolvimento e a participação sejam definitivamente necessários, são essenciais as condições adequadas para que estes deem frutos.

Together We Can? Promoting Action for Marine Conservation

AuthorDr Ana Nuno

A remote and poorly known small island located in the Gulf of Guinea, off the coast of Central Africa, Príncipe (São Tomé & Príncipe) and its people rely heavily on small scale fisheries. When fishing communities on the island tell us that they have to travel farther away, spend more time at sea and increase the amount of fishing gear to get similar amounts of fish that they used to catch near the coast some years ago, it all sounds too familiar. These problems are felt in many coastal areas all over the world and can be particularly severe in small-island developing states, where resources for management are scarce and people often have limited access to other opportunities.

A fishing community in Príncipe / Dário Pequeno Paraíso

Fishing communities are crucial in addressing conservation issues worldwide. Stakeholder participation and fisheries co-management have been recognised as key approaches, particularly when enforcement is challenging due to limited state capacity. But how can we promote individual action and support for measures that improve marine ecosystems? Some might say we need to empower stakeholders. Empowerment has become a popular concept in conservation but, while well-meant, it is often used as a buzzword with unclear claims. How can we move beyond the conservation buzzword?

Fish traders and fisher pulling a boat / Dário Pequeno Paraíso

Focusing on marine conservation and small-scale fisheries in Príncipe, our new paper published in Conservation Letters identifies key determinants of psychological empowerment towards conservation and explores potential management implications. Done as part of a Darwin Initiative project and in partnership with Fundação Príncipe (an NGO based on the island), this research incorporated focus group discussions and household questionnaires (869 people interviewed on an island with around 8000 residents!). We gathered information on, for example, individual and household characteristics; use of natural resources; perceptions about potential interventions; and multiple components of empowerment (e.g. governance, freedom of choice and action, participation, control and collaboration).

Questionnaires in Príncipe / Litoney Matos

We found that people were more likely to believe they could personally make a difference towards protecting the marine environment on the island if they also: felt state law enforcement was currently playing an active role, had higher levels of individual freedom of choice and action, and believed their communities could, collectively, improve outcomes. Respondents who answered “don’t know” about the current marine environment condition on the island were less likely to believe they could make a difference than those who believed the marine environment conditions had remained the same, worse, or better than before.

Considering potential interventions, people with higher levels of self-perceived influence over marine conservation were more likely to recommend specific measures (e.g. creating no-fishing areas). This suggests linkages between psychological empowerment and social acceptability of specific potential interventions.

Why does this matter? Engagement in conservation projects may be influenced by the belief of one’s own abilities to achieve change. As a follow-up project led by FFI and aimed at establishing the first network of marine protected areas in the country now takes place, this information is crucial for understanding how to meaningfully engage local communities and other stakeholders. This is needed for identifying common visions and collaboratively working towards achieving them. As this research shows, this might require tackling several different issues that go hand-in-hand (e.g. access to opportunities, awareness about condition of marine ecosystems and enhancing enforcement), so that people believe their contributions can actually make a difference. While engagement and participation are definitely needed, suitable conditions are essential for those to bear fruit.

World Oyster Day MSc Graduate in Focus: Celine Gamble

Today, for World Oyster Day, we meet Celine Gamble, MSc Biodiversity and Conservation (2017) and BSc Zoology (2015) graduate, now working as a Project Manager at the Zoological Society of London (ZSL).

Hi Celine! Why don’t you tell us a bit about what you are up to now?

I am a Project Manager in the Conservation and Policy department at ZSL and Visiting Researcher at the University of Portsmouth’s Institute of Marine Sciences. I work within the ZSL Estuaries and Wetlands team, which has a varied programme of marine conservation projects, including marine habitat restoration and monitoring of marine species, such as sharks and seals, in the River Thames and outer Thames Estuaries.

During my current role I manage a new project, Wild Oysters, and a Network of restoration practitioners around the UK & Ireland. I work closely with a range of stakeholders including NGO’s, academics, oystermen, government agencies and community groups. My role is very varied, including a mix of physical restoration, science communication, networking, and scientific research.

Find out more about the ZSL Marine and Freshwater Conservation projects here.

A Native Oyster Reef in France /Stephane Pouvreau

In celebration of World Oyster Day, it would be great to understand more about native oysters and why we need to restore them?

The European native oyster (Ostrea edulis) is the only true oyster species that is native to our UK coastlines. Native oysters once formed vast reefs along the coastlines of Europe, forming a dominant ecological feature of our coastal marine habitat.

Despite being relatively small in size (5-11cm), oysters are capable of making some big changes in our marine environment! For that reason, I like to think of them as little superheroes of the sea. A single oyster can filter ~200 litres of seawater per day, which can improve both water quality and clarity. The unique three-dimensional habitats created by oysters support a higher biodiversity of species than the surrounding seabed. Oyster reefs can also increase fish production, by providing a protective nursery ground for juveniles.

Native oyster reefs are now among the most threatened marine habitats in Europe. In the UK and Ireland populations have declined by 95%, as a result of historic overfishing, pollution, and disease. You can still see some remnant populations in the south east of England, west coast of Scotland and the south coast of Ireland. Due to the vast decline of the species, native oysters need active restoration method in order to prevent the species from becoming functionally extinct.

Please could you tell us a little more about what ZSL doing towards Oyster restoration?

Today on World Oyster Day we are very excited to be launching an exciting new marine habitat restoration project in the UK. ZSL along with partners, Blue Marine Foundation and British Marine, we have been awarded £1.18m to deliver the Wild Oysters project.

Wild Oysters is aiming to recover native oyster populations in the UK, and in turn bring back the ecosystem services they provide. Bringing conservation and industry together we will make a space for nature within marina sites. By installing oyster nurseries suspended underneath marina pontoons, we will release the next generation of oyster larvae to the seabed. The oyster larvae will then settle across three new oyster reefs created in British estuaries. In addition, the oyster nurseries will provide us with a “unique window into the ocean” acting as an engagement and education tool.

ZSL are co-founders of the Native Oyster Network, along with the University of Portsmouth, aiming to facilitate the ecologically coherent and collaborative approach to native oyster restoration in the UK & Ireland. ZSL also chair the Essex Native Oyster Restoration Initiative (ENORI), a collaboration between oystermen, government, conservationists and academia. Working towards the Essex estuaries having self-sustaining populations of native oysters, increased biodiversity and sustainable fisheries whilst recognising their cultural importance.

How did your studies at the University of Exeter shape where you work today?

I have developed a focused interest in the restoration of unique marine habitats around the UK. Many of these habitats such as seagrass beds, kelp forests, saltmarshes, and oyster reefs, are often overlooked. I developed a passion for both science communication and marine conservation whilst working and studying at the University of Exeter. My interests and skillset have been developed throughout my degrees, from carrying out UK based marine fieldwork, learning to dive in Cornwall and the extracurricular opportunities available at the university.

During my master’s I had an introduction to many different marine NGO’s and researchers via the Marine Biodiversity and Conservation module. I met Dr Heather Koldewey, who at the time was the Head of ZSL Marine and Freshwater, through this module. I later approached her to be my MSc thesis supervisor, which meant that I learnt a lot more about her research and the wider work of her team.

Any advice for anyone looking to pursue a career in marine conservation?

Reaching out to contacts that you have built throughout your degree, including fellow classmates and recent alumni, is a great place to start. Having a casual chat with someone who is working at an organisation you are keen to work for in the future, provides you with that initial step in the door. I also find that social media and online networking tools work very well for building your knowledge of the types of marine conservation organisations out there. I followed the ZSL Marine and Freshwater social media pages throughout my university degrees, which helped my understanding of the scope of work delivered by the team. This information later became very useful when applying for jobs that came up within the organisation.

Finally, I would say do not let an unsuccessful interview (or a few) put you off applying to the same organisation again if another job comes up. I was offered my first position at ZSL after applying to a few different roles and my third interview attempt.

Lauren Henly 

Lauren is a PhD student with the University of Exeter and Natural England studying functional ecology and behaviour of wrasse to inform management of wrasse fisheries. She provided us with the update below:

 “I’m now in the 3rd year of my PhD. I’ve been developing lots of different methods to assess the sustainability and potential impacts of the Live Wrasse Fishery on the south coast. I’m using genetics to look at the population structure of wrasse along the south coast so we can identify the most effective management unit size, using stable isotopes to predict the ecological impacts of the fishery, and working to ensure the views of other stakeholders (including recreational anglers) are considered when developing management measures for the fishery. It’s great being able to use such a broad range of techniques to address a key issue.”

MSc Graduate In Focus: Zara Botterell

This year we are launching two new MSc courses in Marine Environmental Management and Marine Vertebrate Ecology and Conservation and applications are open now for 2020 start. We are looking back on some of our MSc graduates who have excelled in marine conservation around the world since studying with us.

Today we meet Zara Botterell, MSc Conservation and Biodiversity graduate (2015) and now a PhD student investigating microplastic pollution and zooplankton at Plymouth Marine Laboratory and the University of Essex!

Hi Zara! First off, why did you choose to study at the University of Exeter?

I’ve chosen to study at the University of Exeter twice; to begin with I did my BSc at the Streatham Campus. I was looking to do a broad based biological sciences degree and the course there had a little bit of everything. This was a big draw for me as I didn’t really know what I was interested in the most and didn’t want to specialize too early. The campus was also beautiful, with plenty of green space, in a beautiful city.

Throughout my undergraduate degree I’d naturally gravitated towards ecology, conservation and marine biology and I really wanted to continue with an MSc in these subject areas. My mum actually spotted the MSc Conservation and Biodiversity course and after a quick read I knew it was exactly what I’d like to do. Finances are also big consideration and after some further research I realised that at the time I was also eligible to apply for a scholarship, which I was successful in obtaining.

Immediately after completing my MSc I began a graduate role at the Penryn Campus as a PA and research assistant within the Centre for Ecology and Conservation. After working there for nearly 2 years I was successful in gaining a PhD scholarship at Plymouth Marine Laboratory and University of Essex.

What did you enjoy most about studying your MSc with us at the University of Exeter Cornwall Campus?

The campus is beautiful, with lots of green spaces and being so close to the coast it is perfect for anyone who loves the outdoors and nature.

Everyone in the department was friendly and approachable, where every success of staff and students was celebrated. The field trips were incredible, well planned and thought through to give us a great experience.

I loved the relaxed and friendly environment in Penryn, the campus was beautiful in every season and there are lots of places to explore nearby.

What skills and experiences from the MSc have been most useful in your career?

During my MSc I learnt many transferable skills such as statistical analysis, science communication and developing my academic writing which have been essential to my PhD. I have also been able to build upon my fieldwork experience and public speaking skills which I first developed during my time at Penryn.

The MSc gave me crucial experience in planning and implementing fieldwork and a great foundation knowledge of using the statistical software R and GIS mapping software which I have since built upon. Time management and organization has been key in my PhD. The variety of modules with different deadlines, different types of work i.e. fieldwork, written assignments meant that I had a lot to keep track of, however this was a great experience for my PhD.

Finally, why did you choose your career path and do you have any advice for those looking to pursue something similar?

My advice for anyone who would like to do a PhD would be to work hard, make the most of any opportunities and get experience doing lots of different things. When it comes to applying for a PhD, whilst subject and location are important, take the time to have a chat with your potential supervisors to see how you get on. For 3-4 years they’ll be supporting and guiding you through your PhD and will be integral to your development, experiences, success and of course enjoyment!

Work hard, be organized, do your best and enjoy! Ensure you have a routine and take quality time off.

Any advice for anyone thinking of applying to the University of Exeter?

Apply, you haven’t got anything to lose!

Thanks Zara!

MSc Graduate in Focus: Haley Dolton

This year we are launching not one, but two new MSc courses! We have a new MSc in Marine Vertebrate Ecology and Conservation and an MSc in Marine Environmental Management! Applications to both courses are open now for 2020 start. We are looking back on some of our MSc graduates who have excelled in marine vertebrate ecology and conservation around the world since studying with us.

Today we meet Haley Dolton, MSc Conservation and Biodiversity graduate (2018) and now a PhD student at Trinity College Dublin funded by the Irish Research Council!

Hi Haley! First off, why don’t you tell us a bit about what you are up to now?

After finishing my studies at the Penryn campus, I was lucky enough to work on a couple of short-term projects with researchers from ExeterMarine. I conducted a literature review on Arctic biodiversity for Prof Brendan Godley and Dr Kristian Metcalfe and I analysed video footage from towed cameras deployed on basking sharks for Dr Lucy Hawkes and Dr Matthew Witt. During this employment, I recorded behaviours displayed by basking sharks and their interactions with each other and the marine environment.

I then worked in the teaching lab setting up experiments and demonstrating in practicals, which taught me a variety of new skills! I also continued to volunteer for local marine groups such as Cornwall Seal Group Research Trust and the postmortem team in the ESI who try to figure out why some marine animals have stranded along the Cornish coastline.

Now, I am a PhD student at Trinity College Dublin. My research focuses on the thermal biology and ecology of Atlantic blue fin tuna, sixgill sharks and basking sharks. I collect data from wild, free swimming individuals by attaching devices that record a variety of different things such as body movements and external temperature. From this data, I hope to find out more about each species and how this new information could potentially inform conservation and policy.

So, what did you enjoy most about studying your MSc?

The best aspect for me about studying at the CEC, were the supportive lecturers, researchers and students. There really was a great community feel and if someone could help you out in any way, they would! Their support obviously covered all things academic, but they also supported me as a person, wanted the best for me and really encouraged me in areas where I felt under-confident. For example, before coming to the University of Exeter, I would never show anyone any artwork I would do, but thanks to their encouragement I started to share things I had created with people which resulted in people requesting drawings, purchasing drawings and designing infographics for marine research groups – all things that I would not have come about without the encouragement of people at ExeterMarine!

The lifestyle the Cornish coast could offer was also amazing and I spent many an hour kayaking, on a SUP or snorkeling! As I mentioned above, I also got in contact with a variety of different marine research groups in Cornwall and volunteered for them – this is something I’d highly recommend to any new student to expand your skill set and to meet some great people!

How did the MSc help prepare you for your career in research?

My research project for my masters came about in a slightly unusual way. I had worked in practical marine biology for several years before coming back to education to do my masters degree. I came back to study to learn how to best analyse the data I had been collecting, with one of my main aims being to learn how to use R and GIS (spatial analysis software). Those connections I had made during work with Manx Basking Shark Watch, kindly supplied basking shark location data and allowed me to gain those skills I needed in R and GIS, with great support from my supervisor, Dr Matthew Witt. It was these skills, which helped me to gain employment at the University when I finished my masters.

I also made use of the help offered by the careers service who taught me the skills I needed to gain interviews and through programmes such as the Exeter Award.

Any advice for someone looking to follow a similar career?

Work hard, be kind and be patient. Some of the best job offers I’ve had have come from connections or the unexpected and left field. Take advantage of any opportunity if you are able to and seek out your own opportunities. The opportunity to attend seminars from guest speakers and to network afterwards, were very useful skills to gain. In fact, it was from networking that I knew of the PhD position I am currently in!

As corny as it sounds, the biggest highlight was meeting and getting to know my fellow students. I have met some of my favourite people from doing my masters and have some truly wonderful memories with them. There’s something very special about living somewhere as beautiful as Cornwall and getting to explore and share all it has to offer with your friends!

Any advice for anyone thinking of applying to the University of Exeter?

Go for it! It’ll be hard at times, but you won’t regret it!

Thanks Haley!
