Expedition Overview

During June 2021 a team of us Photographers, Filmmakers, Scientists and Divers took part in the Western Ecology Tour, an expedition that involved diving some of ‘The Best’ of the West Coast of the UK. The Expedition took place between the 17th and 29th of June, and we traveled to 3 key locations throughout the UK. The expedition started out in the Lochs of Scotland and finished along the Pembrokeshire coastline.

The expedition was led by Andy Clark of ATND Services and @fancy_a_brew_podcast. He sought out talent, sponsors, and expertise to aid him in achieving the goals he had planned for the expedition.

The expedition had three main aims; To support scientists who are working to better understand and protect our coastlines, wildlife, and ecosystems, to tell the unseen stories of our hidden coastline, and to promote sustainable adventures.

The expedition had a number of sponsors with all of them supplying equipment to the WET Team, these sponsors included Northern Diver who supplied Cylinders and Dive Lights and a Northern Diver bags for the Crews equipment, Analox who supplied a Nitrox Analyser, Dryrobe who supplied Dry Robes to members of the WET Team, GearAid supplied Cleaning and Repair equipment, Stream2Sea Supplied Alcohol Hand Sanitiser, Neptunic supplied T-Shirts and Rash Vests and Modena Journals supplied Journals to each member of the WET Team to make notes throughout the expedition.

Other sponsors included OThree who donated an array of items for Raffle Prizes and Finisterre who donated a £150 Voucher also for a raffle prize.

A prize raffle was run leading up to the trip, this raised £2,005 with £397 being given to each of the 3 projects that were supported, and the rest going towards supporting the team throughout the expedition. To reduce costs and minimise the teams carbon footprint, we lived life as simply as we could, which we did by staying at campsites.

In total the team collectively covered around 12,500 miles, with travelling taking between 5 – 10 hours to travel between each area of work.

Scotland

In Scotland, our team were supporting Shark & Skate Citizen Science Scotland, with Chris Richard and Dr Lauren Smith. Chris and Lauren are working alongside fisherman and the local community to better understand the movements of the Flapper Skate, an animal that was once in abundance, hence why it used to be called the Common Skate, but it is now classed as a Critically Endangered Species. Chris & Lauren have managed to identify an egg laying site of the Flapper Skate but are unsure of how many animals are using the site and with the surrounding area being used for fishing, it puts the site at risk. Thankfully the specific site is closed to fishing and even diving, Chris & Lauren are working to try and better understand the Skates and learn more about their movements as this will help them place better protections on not just the site itself, but also the routes the Skates are using in and out of the site.

The one thing they mentioned is that the local community are an almost untapped source of local knowledge and resources. Due to the rarity of Flapper Skates Chris and Lauren have put together a Facebook page where local divers, walkers and nature enthusiasts can report their sightings of Flapper Skates and other Shark & Ray species.

We left from Andy’s house in Wigan for around 10:30am and it took us around 10 hours to travel up and arrive at The Wee Campsite which is located on the shores of Loch Carron. As soon as we arrived, we were mobbed by thousands of Highland Midges which resulted in some members of the team having between 10 – 100 midge bites on a single arm. We were warned about this before heading up but we weren’t expecting the sheer amount of them.

The campsite was however situated amongst some of the most breath-taking landscapes and vistas that the UK has to offer. Once we had all set up camp and eaten, it was time to set up our cameras and make sure that we were packed and ready to set off for 9am the next morning.

The First day included diving the shores of Loch Duich with the first Dive Site being outside the Ratagan Youth Hostel, this had a gentle sloping seabed with a muddy bottom. Here lies a huge amount of Short-Clawed Squat Lobster, Brittle Stars, Harbour Crabs and Jellyfish. This dive was unbelievable in terms of the sheer amount of life and is a Macro Photographers dream with life that was not only in high abundance but were also confident allowing you to truly take your time in getting the shot.

The second Dive Site is known by the unfortunate name of the Rubbish Dump, this dive site sits below a small lay by that is known for dumping rubbish, and when you go underwater you see why. The wall was covered in rubbish that ranged from plates, fishing line, car tyres, and even more shocking, was the sheer amount of animal remains with skulls and bags of bones littering the seabed. Even with this sheer amount of waste present at the site, there was life clinging to the debris, from crabs who made makeshift homes beneath the rubbish, Lauren even found a Mermaids Purse that had been wrapped around discarded fishing line but after Lauren did a quick check, she concluded that the egg wasn’t hindered and rather than try and move it and damage the egg she decided to leave it to develop.

After the dive at the Rubbish Dump, Chris spotted what was first believed to be an Otter but as a surprise sighting it turned out to be an invasive American Mink who swam past the team with what was believed to be a Rockling in its mouth, only a few shots were able to be taken before it darted under some rocks.

The final Dive site of the first day is known as School Bay, this is once again a dive site with a muddy bottom. The mission on this dive was to find and photograph a Fireworks Anemone and Sea Pens. The dive site is essentially a bowl that drops to around 25 metres. Chris advised us to follow the slope down into the Bowl at a depth of 20-25 Metres and here we found huge amounts of life from Sea Pens, Sea Whips, Long-Spined Sea Scorpion and of course we found Fireworks Anemone. This site was being swept by a gentle current which was shown by how many filter feeding animals that were present here.

The only problems that we ran into on this site, was entry and exit from the water, as it was over a very rocky beach, followed by shallow areas with thick algae, so extra care was taken when walking and swimming with cameras.

After day one the team returned to the campsite and settled down, after eating and preparing cameras for the second day, to dive briefings for day 2 which were delivered by Chris and Lauren.

Day two in Scotland was a day of drift dives which first lead the team up to Conservation Bay a short drive from the campsite and a short walk down a slope to a gentle shore entry. The dive started on shallow kelp bed, but with a short swim out however had us swimming out into a gentle drift dive, the walls here were covered in Dead Man’s Fingers, Kelp and Anemones. Ollie managed to get some incredible footage here of the walls and life that clung in the gentle drift.

The second dive was another short drive to Castle Bay, a beautiful dive site which had Strome Castle overlooking the bay that we were diving in. The current on this dive was much faster, however manageable when we were trying to capture imagery and footage of the site. The walls on this site were once again adorned with Dead Man’s Fingers, Anemones, and Common Urchins, however the drift was fast enough that it lasted for around 20 minutes before slowing in much slower water. The wall at this point flattened out and became a gentle sandy floor with huge amounts of flatfish, decorator Crabs, Moon Jellyfish and Nudibranchs. This area alone would have constituted a dive all on its own due to the abundance of life that was present.

The final dive of day two was a quiet one with only two members of our team going down for this one, as other members of us went off to photograph the site from above water and conduct drone shots for the Expedition film that is currently in production. It was Chris and Ross who decided to get in for the final dive of the Scottish leg and they dived on a huge Maerl bed, Maerl is a hard Seaweed that forms huge carpets on the seabed and creates a diverse habitat for other wildlife, they reported back after the dive after seeing Nudibranchs, Butterfish and Flame Shells amongst the Maerl beds. Scotland was finished off with Chris and Lauren giving their interviews about what they do at Shark & Skate Citizen Science Scotland, along with some time to take images of some of the expedition’s sponsors.

After the final dive we spent an hour or so filming and taking photographs of expedition sponsors, and the general scenery before heading back to the campsite for the evening. The evening was spent with us chatting about the amazing diving we’d had during the Scottish leg and spoke about the next stop on Expedition WET’s itinerary, this was of course beautiful North Wales.

Tune in for the next entry of Expedition WET’s Trip report where I’ll be collaborating with Co-Scubaverse blogger Jake Davies, where we’ll be talking about Project Seagrass and about what the team saw and achieved during this amazing leg of the journey.

Creature Feature: Dusky Shark

Published

on

In this series, the Shark Trust will be sharing amazing facts about different species of sharks and what you can do to help protect them.

This month we’re taking a look at the Dusky Shark, a highly migratory species with a particularly slow growth rate and late age at maturity.

Dusky sharks are one of the largest species within the Carcharhinus genus, generally measuring 3 metres total length but able to reach up to 4.2 metres. They are grey to grey-brown on their dorsal side and their fins usually have dusky margins, with the darkest tips on the caudal fin.

Dusky Sharks can often be confused with other species of the Carcharhinus genus, particularly the Galapagos Shark (Carcharhinus galapagensis). They have very similar external morphology, so it can be easier to ID to species level by taking location into account as the two species occupy very different ecological niches – Galapagos Sharks prefer offshore seamounts and islets, whilst duskies prefer continental margins.

Hybridisation:

A 2019 study found that Dusky Sharks are hybridising with Galapagos Sharks on the Eastern Tropical Pacific (Pazmiño et al., 2019). Hybridisation is when an animal breeds with an individual of another species to produce offspring (a hybrid). Hybrids are often infertile, but this study found that the hybrids were able to produce second generation hybrids!

Long distance swimmers:

Dusky sharks are highly mobile species, undertaking long migrations to stay in warm waters throughout the winter. In the Northern Hemisphere, they head towards the poles in the summer and return southwards towards the equator in winter. The longest distance recorded was 2000 nautical miles!

Very slow to mature and reproduce:

The Dusky Shark are both targeted and caught as bycatch globally. We already know that elasmobranchs are inherently slow reproducers which means that they are heavily impacted by overfishing; it takes them so long to recover that they cannot keep up with the rate at which they are being fished. Dusky Sharks are particularly slow to reproduce – females are only ready to start breeding at roughly 20 years old, their gestation periods can last up to 22 months, and they only give birth every two to three years. This makes duskies one of the most vulnerable of all shark species.

The Dusky Shark is now listed on Appendix II of the Convention on the Conservation of Migratory Species (CMS), but further action is required to protect this important species.

Scientific Name: Carcharhinus obscurus

Family: Carcharhinidae

Maximum Size: 420cm (Total Length)

Diet: Bony fishes, cephalopods, can also eat crustaceans, and small sharks, skates and rays

Distribution: Patchy distribution in tropical and warm temperate seas; Atlantic, Indo-Pacific and Mediterranean.

Habitat: Ranges from inshore waters out to the edge of the continental shelf.

Conservation status: Endangered.

Creature Feature: Undulate Ray

Published

on

In this series, the Shark Trust will be sharing amazing facts about different species of sharks and what you can do to help protect them.

This month we’re looking at the Undulate Ray. Easily identified by its beautiful, ornate pattern, the Undulate Ray gets its name from the undulating patterns of lines and spots on its dorsal side.

This skate is usually found on sandy or muddy sea floors, down to about 200 m deep, although it is more commonly found shallower. They can grow up to 90 cm total length. Depending on the size of the individual, their diet can range from shrimps to crabs.

Although sometimes called the Undulate Ray, this is actually a species of skate, meaning that, as all true skates do, they lay eggs. The eggs are contained in keratin eggcases – the same material that our hair and nails are made up of! These eggcases are also commonly called mermaid’s purses and can be found washed up on beaches all around the UK. If you find one, be sure to take a picture and upload your find to the Great Eggcase Hunt – the Shark Trust’s flagship citizen science project.

It is worth noting that on the south coasts, these eggcases can be confused with those of the Spotted Ray, especially as they look very similar and the ranges overlap, so we sometimes informally refer to them as ‘Spundulates’.

Scientific Name: Raja undulata

Family: Rajidae

Maximum Size: 90cm (total length)

Diet: shrimps and crabs

Distribution: found around the eastern Atlantic and in the Mediterranean Sea.

Habitat: shelf waters down to 200m deep.

Conservation Status : As a commercially exploited species, the Undulate Ray is a recovering species in some areas. The good thing is that they have some of the most comprehensive management measures of almost any elasmobranch species, with both minimum and maximum landing sizes as well as a closed season. Additionally, targeting is entirely prohibited in some areas. They are also often caught as bycatch in various fisheries – in some areas they can be landed whilst in others they must be discarded.

IUCN Red List Status: Endangered
