Scientists at Sea Podcast – Sail Against Plastic Part II

Show notes

You might remember that earlier in the series we spoke to Flora Rendell and Lowenna Jones about an arctic sailing expedition they were about to embark upon in 2018 titled ‘Sail Against Plastic’. Well they’ve been there, done that, and got the microplastic samples to prove it. If you didn’t catch the episode, I would recommend having a listen to it here.

In short, Sail Against Plastic was a two-week multidisciplinary research expedition taking place in the waters off Svalbard. Sailing aboard the Blue Clipper, the team investigated the impact of plastics and noise pollution on this arctic environment whilst producing film, photography and artwork to capture the experience and illustrate their findings. You can find out about the background of the expedition on the Sail Against Plastic website.

This time Flora is joining us with Daniel Osmond, with both of them being greatly involved in the scientific aspect of the expedition. Since recording they have both gone on to secure PhDs, well done to both!


“It was just a great example of how different people with different experiences, interests and skill sets can all come together”


About our guests

Flora Rendell – Scientific Director

Flora is a current postgraduate research student at the University of Exeter, with a strong interest in science outreach and the effects of anthropogenic stressors on populations and habitats. Her key interests in aquatic habitats and the conservation and management of local sites around the UK.

 

 

Daniel Osmond – Scientific Officer

Daniel is an MSci Zoology Student at the University of Exeter. During his degree program and ongoing work in Wotton’s research group he has been spurred on to use ecological knowledge to help us to protect threatened ecosystems.

Scientists at Sea Podcast – Microplastics and Sharks with Kristian Parton

Show Notes – Mircoplastics and Sharks with Kristian Parton

 

Of all the pollutants impacting the environment, plastics are perhaps among the most talked about and campaigned against in recent years. We’ve had members of Sail Against Plastic on the podcast before to discuss the presence of plastics in some of the most remote areas of ocean, but in this episode we take a look into how some plastics penetrate further – the invasion of food web ecology by microplastics.

 


 

Kristian Parton 

As an undergraduate with the University of Exeter, Kristian developed a strong interest in

marine conservation, specifically elasmobranch (shark and ray) ecology and biology. After being involved in several shark conservation projects around the world, from Mozambique to the Philippines, Kristian went on to start his current research as a Master by Research post-graduate investigating plastic ingestion in several North-East Atlantic shark species; Tope, Dogfish, Smooth-hound, Bull huss and Spurdog. The project aims to investigate whether diet and foraging behaviour has an influence on the consumption of micro plastic, and its accumulation within the digestive tracts of these species.

 


 

Is it a dog? Is it a fish? No, it’s a shark…

Kristian’s research has a broad focus on several small to moderate shark species found in the waters of the UK and North-East Atlantic, most of which are unknown to the wider public – all too often over-shadowed by larger, more cinematic species. The most common species that Kristian works with is the Lesser Spotted Dogfish…or the Small Spotted Catshark…or some may say the Murgey (Scyliorhinus canicula). Whatever you wish to call it, this species exhibit beautiful spotted patterns on a pale body, and are a delight to see in the wild for those lucky enough to spot them among the kelp beds. Though regularly caught in numerous trawl and gill net fisheries, they are not often eaten among Cornwall, though are put to use as bait while Kristian claims a few from local fishermen for science. The exact status of their stocks is unknown though they are thought to be fairly numerous and common. Unfortunately, this is not the case for many of the other sharks that Kristian samples.

For more information on the fisheries of S. caniculla, and other shark and/or marine species click here.

 


 

Fake Plastic Seas 

With so much plastic floating around, there is no surprise that it finds its way into the food webs of marine ecosystems. Our news feeds are battered by reports of stranded marine animals whose stomachs are littered with plastics, clips of animals mistaking plastic bags for their primary food sources, and new studies quantifying the presence of micro-plastics in almost all areas of nature. The problem is more than just full bellies of unnatural content, which in of itself is a great concern. Studies have shown that plastics may contain chemical traces that can disrupt systems by which organisms regulate and produce hormones, leading to further and exacerbated biological implications.

To find out more, have a listen to the episode.

Scientists at Sea Podcast: Sail Against Plastic

Show Notes

 

 

 

Guests – Flora Rendell and Lowenna Jones

 

 

 

Sail Against Plastic started as an idea to simply undertake a sailing expedition, over just a few months it developed into an Arctic mission to investigate unseen pollutants, namely microplastics and noise pollution.

Why the Arctic?

It is well documented that plastic debris has been circulating around our oceans via 5 ocean gyres. It is now thought there maybe a sixth gyre that carries plastic up into the Arctic circle. Recent discoveries supporting this theory have shown that plastic has been found in sea ice.

 

“As sea ice melts that could be opening up more microplastics that have been trapped in that sea ice… it shows that we’ve been influencing the world for a long time”

These pieces of plastic aren’t necessarily what you would expect, while there plastic bottles and bags found in these areas, there may be an even greater prevalence of microplastics, tiny pieces of plastic debris resulting from the breakdown of consumer products and industrial waste.

 

“It’s not these big large pieces of plastic, it’s not a floating island that we’re going to find’

 

At the time of recording, the team, a diverse group of scientists, artists, environmentalists, photographers and videographers, were just a few days away from setting sail on the Barents Sea from Svalbard aboard the Blue Clipper.

“I think the main thing is making issues that are so strongly linked to humans… making you feel emotive about them… through art and through film, people will feel emotive about it and will care, we hope”

 

“And make it relevant to people in the UK and Europe and connect communities that are halfway across the world that have similarities and can work together to find a solution to our crazy plastic addiction”
