Student marine biodiversity survey at Lulworth Cove
Experiential learning in coastal ecology and conservation
Students participated in a comprehensive marine biodiversity survey at Lulworth Cove, a Marine Conservation Zone on the UNESCO Jurassic Coast, to gain hands-on experience in ecological fieldwork and environmental monitoring. Lulworth Cove is a naturally sheltered omega-shaped bay in Dorset featuring extraordinary habitat diversity, from intertidal rock pools to shallow kelp beds, and a unique freshwater-saltwater gradient. The survey directly supported the General Biology II course curriculum, giving students practical tools to assess ecosystem health, document biodiversity, and contribute to real conservation efforts.
Understanding marine biodiversity through hands-on fieldwork
Through systematic ecological surveys in both intertidal and subtidal environments, students explored how coastal ecosystems function and how human activities impact marine life. The visit revealed how standardised survey methods generate data that informs conservation management, climate change monitoring, and marine protected area assessments.
The visit included the following:
Intertidal zone surveys: Students conducted vertical zonation transect surveys along the shore, documenting how species assemblages shift from high to low tide marks. They characterised rock pools across different shore heights, recording physical parameters, species diversity, and habitat complexity. This work revealed the physiological tolerances that drive zonation patterns and demonstrated how intertidal communities respond to desiccation stress, temperature variation, and wave exposure.
Subtidal snorkelling surveys: Working in buddy pairs, students conducted systematic surveys at multiple depths in shallow subtidal waters (0.5-3m). They estimated percentage cover for seaweeds and invertebrates, counted mobile species, and documented fish assemblages. This hands-on work showed how habitat structure influences biodiversity and how kelp beds support commercially important species.
Freshwater-saltwater gradient investigation: Students surveyed a unique freshwater stream entering the cove, documenting species distribution along a salinity gradient. They observed the transition from marine to freshwater communities over a short distance, including the discovery of planarian flatworms, demonstrating how organisms adapt to varying environmental conditions.
Pollution and human impact assessment: Students conducted quantitative litter surveys both on shore and underwater, categorising marine debris by type and mapping its distribution. They assessed physical disturbance from trampling and other human activities, connecting their observations to real-world conservation challenges facing Marine Conservation Zones.
Climate change indicator monitoring: Students identified and recorded warm-water and cold-water indicator species, learning how biogeographic range shifts provide evidence of ocean warming. This work connected their local observations to global climate change patterns documented.
Key benefits for students included:
- Practical conservation skills: Students gained experience in standardised ecological survey techniques used by professional marine biologists and conservation organisations, including quadrat sampling, transect surveys, species inventories, and pollution assessments.
- Scientific data literacy: Students collected, recorded, and compiled quantitative ecological data, learning how systematic observation and measurement underpin evidence-based conservation decisions.
- Biodiversity awareness: Students identified 30-50+ species of seaweeds, invertebrates, and fish, developing appreciation for the remarkable diversity of UK coastal ecosystems and understanding why these habitats require protection.
- Sustainability and environmental stewardship: Students directly observed human impacts on marine environments and learned how their data contributes to monitoring ecosystem health, tracking pollution, and informing management actions in Marine Conservation Zones.
- Teamwork and field skills: Working in buddy pairs and split teams, students developed collaboration skills while gaining confidence conducting research in challenging outdoor environments.
- Connection between theory and practice: Students applied classroom concepts about ecology, zonation, adaptation, and environmental science to real-world field situations, seeing how biological principles manifest in nature.
Student perspective
“It’s been amazing! I never thought I would be able to do this stuff as a freshman, especially to be able to come here and it’s a beautiful day, and learning all this stuff about snorkelling and diving, and then also about all the cool creatures here, it’s just been really amazing. It’s been a really cool experience and I’ve really enjoyed it!”
“It’s been really fun! We got to swim through the kelp and find all kinds of seaweed and animals, and that was really cool! And we got to dive down and look at the organisms on the rocks. And now we’re catching fish and crabs!”
“It’s been super cool! I started off on the shore team in the morning and I’m in the water team this afternoon, which is pretty cool because the tide is lower, so we get to see a lot of these super cool rocks. I found a tube worm, which was really awesome! …Also, I love the ecology aspect and the climate awareness aspect, because seeing a lot of the kelp that’s a little bleached and the shells that are showing, that are climate indicators is really eye-opening and it’s an awesome research opportunity!”
Faculty perspective
“Experiential learning is at the heart of what we do at Northeastern University London. This marine biodiversity survey gave students the opportunity to conduct real scientific fieldwork that contributes to understanding coastal ecosystem health. Watching students discover the incredible diversity in rock pools, document climate change indicator species, and grapple with the reality of marine pollution was immensely rewarding. They weren’t just learning about ecology – they were doing ecology.”
“It is amazing to see students progressing from learning about a topic to making their own contributions. The enjoyment in students faces when they start recognising organisms, only seen in learning materials or labs, in the wild is highly rewarding. But the marine biodiversity survey at Lulworth Cove gives students many more insights than just the ecological outcomes.
A lot of logistics and training are required to safely perform a marine survey, and students are eager to learn about these otherwise invisible soft skills about logistics, risk assessments, and emergency response skills. This allowed students to not only perform the scientific tasks and learn about the environment, but also to grow together as a team who is mutually supporting at all stages of the survey.”
