Sail the Hebridean Sea in Scotland aboard research vessel Silurian and assist with dolphin and whale monitoring activities. Volunteers will collect visual and acoustic data on the various species of cetacean found in the area.
We have places for volunteers to join throughout the year.
Individuals, groups and students doing research all welcome.
Cost including accommodation, food, training by researchers and boat fuel starts from £845
During the expedition you will live-aboard the research yacht Silurian, exploring the Hebrides while collecting visual and acoustic data on the various species of whale, dolphin and porpoise (cetacean) found in the study area. Images will also be collected during encounters for Photo-ID analysis; Photo-ID is a tool used to identify individuals using distinguishable marks on their dorsal fins. 24 species of cetacean – nearly a third of the global total – have been recorded in the Hebrides. However, the most commonly encountered species, and target of specific research include:
• The minke whale; researchers have documented approximately 122 individuals in the area using Photo-ID. Some return to the same areas annually while others are just passing through.
• The harbour porpoise; some of the highest densities of porpoises in Europe are found in the Hebrides. They are fairly elusive cetaceans, rarely approaching vessels or leaping clear of the water.
• The bottlenose dolphin; Scottish bottlenose dolphins are at the most northern extent of the species’ range and are consequently the largest. Photo ID suggests that Hebridean waters host one of the UK’s three resident populations.
• The white-beaked dolphin; we have been investigating population structure differences between east and west coast Scotland white-beaked dolphins, in particular the differences between vocalisations. This research will contribute directly to how this species is managed in UK waters.
• Common dolphins are seasonal visitors, recorded mainly between April and October, in groups sometimes containing several hundred individuals. Research suggests that common dolphin numbers have increased in the Hebrides in recent years; in fact the encounter rate aboard Silurian has almost doubled in the last decade. Common dolphins are very inquisitive and will actively approach boats and play in the bow-wave.
The species outlined are the most commonly sighted; however we also have annual encounters with Orca, Risso’s and white-sided dolphins and sunfish (towards the end of summer). In the Hebrides, the occasional humpback whale, sperm whale, sei whale, bottlenose whale and fin whale have also been recorded, although the chance of seeing these is very small.
In the study area, basking sharks are frequently encountered between May and October and are seen in high numbers around the islands of Coll, Tiree and Hyskier. Research conducted shows that basking shark sightings fluctuate greatly between years; further research will help us to understand basking shark distribution in the Hebrides – fast emerging as one of the most important areas for this second largest fish in the world, with unusual behaviours such as courtship and breaching regularly observed. The data collected aboard Silurian will allow for a better understanding of cetacean species, both locally and internationally. The resulting information will feed into more effective conservation strategies’, ensuring the Hebridean marine environment is safeguarded for future generations.
Despite the EU labeling the Hebrides as one of the last 'wild' coastal environments and one of the best examples of Atlantic maritime coast in Europe, very little was known about the cetacean species found there until research began in the mid-1990’s. Since then, researchers have been monitoring the area, recording encounters (alongside other environmental factors) and taking images for analysis.
There are many threats faced by cetaceans in the area. Entanglement from ghost gear and/or static fishing gear (creel ropes) is an issue, alongside general marine litter and ingestion by marine life. Noise pollution is also an issue in the Hebrides, with research dedicated to realising the impact of Acoustic Deterrent Devices (deployed by aquaculture sites to scare predators off) on porpoise displacement. Pollution is an issue, recent studies into PCB contamination reveal that European cetaceans are some of the most contaminated in the world, leading to low reproductive rates (among other things). It’s believed that this might be the reason that the West Coast Community of orca – a highly vulnerable population, numbering only 8, found off the west coast of Scotland and Ireland – has never reproduced successfully. Depletion of food stocks and habitat degradation are yet more threats faced by cetaceans locally.
Sailing on board the Silurian whilst being a dolphin and whale research volunteer is a truly fantastic way to explore the west coast of Scotland. Anchoring each evening in secluded island bays will give you the opportunity to hop ashore and explore the otherwise inaccessible vast beaches, rugged cliff tops and abandoned villages. A whole wealth of British wildlife will also be revealed from carnivorous plants to beautiful orchids and rare bees to majestic eagles.
Our Tobermory expeditions allow for the monitoring of the Southern Hebrides (Islay, Jura, Colonsay, Gigha and the slate isles) alongside the Argyll Isles (Mull, Iona, Staff, Treshnish, Tiree and Coll) and the Small Isles (Rum, Eigg, Canna and Muck).
These surveys will monitor for the resident populations of porpoise and bottlenose dolphin, alongside noting the arrival of our seasonal visitors. Spring is a fantastic time to visit the Hebrides with the arrival of thousands of nesting seabirds and generally more settled weather. Shorter daylight hours also mean shorter survey days so a perfect choice for those who want a more relaxed experience.
2nd – 8th May: £895
11th – 17th May: £895 (Fully Booked)
These surveys will monitor the Hebrides during the height of the summer season so you can hope to expect sightings of seasonal visitors (minke whale, common dolphin) as well as basking sharks. The hours of daylight are at their maximum so expect long days on survey effort if joining one of our mid-season expeditions.
28th June – 9th July: £1,395 (Fully Booked)
12th – 20th July: £1,195 (Fully Booked)
14th – 25th August: £1,395
Departure from Kyle (where the bridge to Skye meets the mainland) allows for the monitoring of the Small Isles, Skye (and its surrounding islands, including the Sound of Raasay – the deepest inshore waters in the UK), Barra, South Uist and the Inner Minch.
5th – 13th June: £1,175 (Fully Booked)

You will spend the duration of the project living aboard Silurian, a fully-equipped research yacht. Silurian has surveyed thousands of nautical miles of Hebridean waters since being purchased in 2002; spending the field season monitoring as far north as Cape Wrath, as far south as Kintyre and as west as the St. Kilda archipelago. Prior to joining the team, Silurian was used as a filming platform in the BBC series The Blue Planet.
Silurian can accommodate up to six volunteers and has a crew of three: Skipper, First Mate and Science Officer. Silurian is a hard-working research vessel, not a luxury cruiser, although participants find her a safe and comfortable living environment. There are three volunteer cabins in the forward section of the vessel. Each of these contains two berths and a small amount of storage space for personal belongings. Two of the cabins have bunk style beds and the other cabin has a twin double berth. Participants have access to their own toilet and shower room. Internet access during the project is variable, but more often than not inaccessible. There is a large saloon space in the heart of the boat where most time will be spent in the evening eating and socialising. The galley is very well equipped for a yacht, with fridge and freezer space.
Both volunteers and research assistants will be responsible for cooking on a rotation basis, though meal plans are typically set out by the crew. Enough food to last the duration of the expedition will be loaded aboard Silurian prior to the rendezvous. Local island meat, bread and rolls are sourced. Fruit and vegetables are sourced from local companies too. A whole variety of different diets can be catered for aboard, simply let the researchers know if you have any requirements. Water is limited and volunteers are encouraged to conserve as much as possible during the expedition. The dishwashing and general cleaning of the house are further shared duties.
As the duration of the project will be spent aboard a research yacht, there will be no need for transport during the expedition. In the evenings, volunteers may have the opportunity to venture ashore to explore the many Hebridean islands, however many of these are uninhabited, let alone have roads!
There are three rendezvous locations for this project: Tobermory (on the Isle of Mull), Kyle of Lochalsh (on the mainland where you’ll find the bridge to the Isle of Skye) and Ullapool (the most north-western town on the Scottish Mainland). All are accessible via public transport links.
If flying, it is advised that you fly into Glasgow for Tobermory rendezvous and Inverness for Kyle of Lochalsh and Ullpool rendezvous. However, you will be able to access all locations by flying into both Glasgow and Edinburgh, with public transport links to all.
The west coast of Scotland, while outstandingly beautiful, is not known for its tropical climate and rain is prevalent throughout the year. Even on bright, sunny days the added wind chill of being at sea can affect the temperature dramatically, so please bear that in mind when packing your equipment. Sea-faring waterproofs are provided, designed for use offshore, they are effective at keeping the west coast weather at bay. The sea is a highly reflective environment and you are therefore advised to bring sunscreen and sunglasses for protection from the glare, even when it's cold enough for a woolly hat! Midges are prevalent in west Scotland during the summer months and, although they are likely only to be encountered during evening shore leave, they can be very irritating. It is advisable to bring insect repellent for trips ashore.
No experience is required as full training will be provided on board. Volunteers should be aged 18+, and comfortable living aboard a yacht and maintaining survey effort in all weathers. Good eyesight and hearing is important to undertake the data collection during the survey. The Hebridean islands are the remotest parts of the UK and so access to medical services is limited, if you suffer from a serious condition you may want to consider a project closer to civilisation.
Below is an interactive map showing the location of the project:
The Hebrides includes some 550 islands distributed over approximately 40,000 square kilometres, encompassing all inshore waters found off the west coast of Scotland. There are a wide range of marine habitats of international importance: rocky reefs, cold water corals, turbulent tidal streams and deep-water channels. Complex oceanography is a result of interactions between the Atlantic Ocean and the Celtic and North Seas, coupled with complex undersea topography – the result is an area rich in biodiversity. The area was classed by the EU as “On land, the coastal landscape is magnificent, featuring sea cliffs and stacks, wonderful white sandy beaches, moorlands, mountain ranges, sea lochs, salt marshes and machair (a rare coastal environment exclusive to the north and west of Scotland and Ireland)."
During the volunteer expedition, the route travelled will be dependent on weather conditions and also areas where survey effort is lacking. Each evening we will anchor in a different location, usually off one of the many remote islands in the area. Opportunities for shore leave and exploration will be available each evening once the survey work is complete. Each of the Hebridean islands has its own unique character and is steeped in Highland history, tradition and culture. What is most evident within the Hebrides is the dramatic variation in the Scottish landscape; the west coast of Scotland indisputably possesses truly spectacular scenery, the last true wilderness in the UK.
Priscilla Marsden, volunteered in September 2016:
"I had a brilliant time on board Silurian. The crew were very knowledgeable and happy to share their knowledge and looked after us very well. Although the weather was not particularly good for spotting mammals, we saw several different species including a large group of harbour porpoises, when all the books say they are only seen singles or in pairs. Silurian herself is a lovely boat and felt very safe and secure. The evenings were spent playing various games and eating a variety of meals prepared by different people each day. The combination of beautiful scenery and wildlife sightings was added to by one evening being able to see the Northern Lights, a first for me. Overall an excellent experience, one which I would happily repeat."
“For those of you who want to do more than just read about adventure stories out on the far seas, I urge you to leave the world as you know it behind, and take the plunge” September 2015
“An “alternative holiday” doesn’t even begin to describe my experience upon Silurian. From breath-taking views, the vast knowledge and presentations given to us by our scientific officers, to the evening trips ashore” September 2015
“Volunteering aboard the Silurian is something you can do on different levels. It can be a holiday with a difference; it can be an educational opportunity; it can be the first fleeting step towards a fully-fledged career in conservation. First and foremost, though, it is a contribution. Come and do this ….if you want to contribute in a small but lasting way to something that is real, concrete and tangible” August 2015
“On our last evening on the sea I can’t help but believe that the Hebrides of Scotland have lured us in with their danger, wilderness and raw beauty. I know I don’t want to go home!” July 15
“My heart is gladdened by being able to help in the meaningful and important research work that we carry out aboard Silurian and the HWDT.” May 15
“These islands here in the Hebrides are some of the most beautiful I have ever seen. “ July 2015
