Regular beach cleaners with our local group at Half Moon Bay, Heysham will know that we always take a survey of the litter collected and this information is put into a database held by MCS. We thought it would be interesting for people to see the attached graphs which show some of the changes in litter at HMB since 1998.
Although this data may not be very exact it does show some encouraging changes for example items described under “sanitary” have reduced. Perhaps the “don’t flush” campaigns are working?
Plastic bag numbers have come down, though the amount of plastic in general has increased although oddly, glass has increased from 72% to 76% of the total rubbish on the beach.
The local MCS group doubled the survey area at HMB in April 2018 but the amount of litter collected has not increased which is very encouraging. Although sometimes our volunteers are a bit disappointed that there isn’t as much to do!
MCS value the data we submit and believe it to be important for their monitoring purposes. They have asked us to continue to beach clean and survey at HMB.
So, we still need your support and really appreciate everyone giving their time and efforts. Of course you can beach clean/litter pick anytime, anywhere so why not carry out a 2 minute litter pick nearer home?
After a string of possible dates this year that we were unable to get in at Roa Island we finally managed a dive on Friday (we had to bring it forward a day to miss the worst of the weather). It was well worth the effort. Visibility was only 2 to 3 metres at best but that is plenty to search the reef for interesting macro life. Our species list – which for invertebrate species goes back to 1968 – grew by at least 2 new species. First to be found were several Goldsinny (Ctenolabrus rupestris), unusual not just as a first for that species, but the first species of wrasse to appear on the list.
The next was a nudibranch (that’s a fancy name for a sea slug) called Jorunna tomentosa (pictured below) – it doesn’t have an English name. Both are common species around the coasts of the UK, so of course may have been here all the time, but this is the first time we have them on record here.
There are many predators in the marine ecosystem and animals have a variety of strategies to help them find food, and avoid being eaten. The Long-spined Scorpionfish is a master of disguise – hiding in plain site by blending its skin colour in with its background; if a crab or small fish comes too close they will be grabbed at lightening speed, predators large enough to tackle it will need sharp eyes to see it, and if they do this fish has a back-up plan – the eponymous long spine on its gill cover, just visible in this picture.
Perhaps the most suprising thing about the dive was the water temperature – depending in depth it ranged from 18ºC to 20ºC. I don’t think that I’ve dived in water that warm either at Roa Island or anywhere else around the Irish Sea. Unfortunately I can’t check my dive logs after a computer glitch trashed them a couple of years ago.
Thanks to Philip and Rebecca for providing shore cover!
After a year’s absence, it was good to be able to attend the Kite Festival at Morecambe again this year. Our ‘new’ gazebo had its first outing – and proved to be very successful, bringing us a bit closer to the people moving along the prom viewing the kites!
There was quite a lot of interest in our stand, and we are greteful to everyone who came to chat to us, as well as a number of donations. The local area group made £26.80 from donations, and sales of pin badges raised £42 for National MCS.
Saturday, coincided with Armed Forces Day, so we were treated to a Dakota fly over and parachutists! Sunday was more difficult, with high winds causing us to close down a little early for fear of loosing our gazebo!
While the amounts of money raised are small, as long as we can break even, events like these allow us to ‘spread the word’ about quite how special the marine life around the UK is, and how much it deserves our protection. On this score, it was great to see how many younger visitors were interested in our marine life, and clued up as to some of the threats it faces…
A big thank you to everyone who turned out for the beach clean at Half Moon bay on the 5th June – a decidedly un-summery evening. The photo is by Ian Croucher, having his first taste of a beach clean, and looking to set up or join similar events with colleagues from work on the railways, so we wish him all the best!
Again the beach was relatively clean – which is good news, though we are seeing more wet-wipes than has been the case in the past. Again a quick reminder to anyone who has not got the message – don’t flush wet wipes. Despite what it says on the packet, they don’t belong down the loo.
It is my sad duty to report that Betty Green has died. Betty and her husband Gil were great supporters of the group since its inception, and keen divers into their seventies! Betty’s love for, and understanding of, marine life was outstanding, and a great inspiration to all of us blessed to have known her.
I know that many of us hold fond memories of her, diving, or on shore walks. The photograph (by Chrissy Ryan) is on one of our trips to Lochaline. She will be missed..

Two talks about two very different types of destroyer – Lewis Bambury will talk about Orkney, including a look at how events from 100 years ago gave the islands some of the best diving in the world. Gordon Fletcher will look at the colourful world of sea slugs, giving you the chance to hear about the feeding habits of these predatory carnivores, their unusual sex lives, and the extraordinary defence mechanisms they utilise to avoid being eaten by larger predators!
These talks will be followed by the local group AGM.
Wednesday, 13 March: 19:30 – 21:00 at the Gregson Centre, 33 – 35 Moor Gate, Lancaster LA1 3PY.
Admission £3.00, everybody welcome!
Man and animals are in reality vehicles and conduits of food, tombs of animals, hostels of Death, coverings that consume, deriving life by the death of others. Leonardo da Vinci
Plants are rather different – quietly converting sunlight into the food we need to survive; the shepherd with his grazing flock is the subject of a painting, the meadow, a beaucolic backdrop. In the worlds oceans, however, the plants that form the meadow are microscopic – completely invisible to the naked eye. Indeed, for most of the 20th century, the main players remained elusive even to the best optical microscopes!
Over the last decade or so satellite imagery, coupled to unmanned submersibles, have begun to reveal the true extent of marine ‘plant life’. We find a complex, dynamic pattern of blooms, and rapid disappearances keyed to the seasons, currents and climate. Alongside this, genetics has begun to unravel the complexities of the interrelationships between the different groups of marine plants – and animals…
Join us on Wednesday 13th February between⋅19:30 and 21:00 at the Gregson Centre, 33 – 35 Moor Gate, Lancaster LA1 3PY for a personal look at some of the recent research in this area. Admission £3.00, everybody welcome!
At our next meeting, members of the group will take personal views on the subject of photography around UK coastline. This will include a look at the photographic equipment they use, and the challenges they face in getting a ‘good’ photograph. Main speakers: Gordon Fletcher (film), Lewis Bambury (digital), Jo Kaye (macro).
Meet up at 11:00 at the Half Moon Bay cafe car park (LW 13:30), or join us on the beach if you arrive later. Please bring suitable clothing and tough gloves (gardening or similar) for picking litter. Organised by Kathy MacAdam

A big thanks to everyone who came along to our meeting, ‘Loch Sunart and the Isle of Gigha’ on the 14th November, which looked at the life in two very different post-glacial marine-scapes. Gordon did an excellent job exploring some of the fascinating life in Loch Sunart, which included flame shells (photo. above by Gordon Fletcher) and hard corals.
The life around Gigha might be described as prosaic – almost terrestrial in that is is dominated by large marine plants (though this is unusual for a marine ecosystem!). It did, however, open up a brief discussion about invasive species, led by observations of wireweed (Sargassum muticum) and Codium (tomentosum/fragilis). The problem with introduced species is that they are extremely difficult to remove once established, and the process of removal may be damaging to many other species in the area. For Codium, studies suggest that our native species are not being overwhelmed. Wireweed is hard to ignore, being a large spreading kelp species, but is also being colonised by local wildlife; so while it clearly competes with native species, it also presents opportunities for local wildlife. The final picture, I felt, was of quite a healthy mix of marine plant and animal species around the island.
