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 – Climate Change, why don’t people act? With Catherine Leyshon

Show Notes

In the last episode we spoke with Paul Butler and Annette Broderick about climate change and how this impacts their work on bivalves and turtles respectively. We also discussed some of the key points of the IPCC’s latest climate change report. If you would like to check that out, click here.

This time, we’re taking a slightly different approach in a chat we had with Professor of Human Geography, Catherine Leyshon. Specifically, we discussed the reasons why, in the face of overwhelming evidence, we appear to do very little in response.

The discussion ranges from why people might struggle to make small, every day changes, right through to governmental/international levels.


“We’re not really set up as a society to reward good behaviour, we tend to sanction bad behaviour”


Why don’t some actions work?

This seemed like a good idea in principle, but ultimately didn’t work out, we’ve collected a few pieces relating to this. You can read about what the taxes were, what impact they had, why they were abandoned, and what has happened as a result:

What was the emissions tax?

“Australia records biggest emissions drop in a decade as carbon tax kicks in”

“Australia abandons disastrous green tax on emissions”

“Australia’s greenhouse gas emissions soar in latest figures”

 


What actions might work?

Shifting Shores

In the UK we are seeing some changes. For example, the National Trust have introduced their Shifting Shores project, where they will now be focusing on adapting to changes at their coastal sites, rather than trying to prevent change.

For those of us in Cornwall, Mullion harbour wall is a particularly relevant example, you can read about the challenges the National Trust have faced with this here.

In 2012, Catherine co-authored a paper going into greater depth about this, which you can find here: Shifting Shores: Managing Challenge and Change on the Lizard Peninsula, Cornwall, UK


As Ethan mentioned in the episode, we are seeing some other actions, such as: Dutch parliament to set target of 95 percent CO2 reduction by 2050. There are several other areas covered in the episode, but to find out more you’ll need to give it a listen!


You can also read the IPCC Climate Change Press Release in full here.


Associate Professor Catherine Leyshon:

Catherine is a human geographer whose work combines landscape ecology, social relations and climate change. Catherine’s work on climate change is interesting for many reasons, but one aspect that really makes it stand out is its focus on local communities here in Cornwall. Studies can all too often focus on the distant impacts of climate change, but numerous studies from Catherine help to highlight the potential changes occurring on our door step.

Scientists at Sea Podcast – Climate Change, Turtles, and Bivalves

Show Notes

In this episode Ethan and Ben discuss the latest Climate Change Report released by the IPCC (Intergovernmental Panel on Climate Change), with Professor Annette Broderick and Dr. Paul Butler. As well as covering key points of the report, Annette and Paul tell us about how climate change is a significant aspect of their current research.

 

About our guests:

Annette Broderick – Professor of Marine Conservation

Profile

Annette’s research investigates the exploitation of marine vertebrates, with a primary focus on marine turtles. The thermal environment is particularly important for turtles, so the potential effects of climate change could have a big impact on these populations. Listen to the episode to find out more.

If you’re interested in turtle conservation, Annette runs a long-term field study in northern Cyprus which takes on volunteers each year, you can find out more here

 

“The most biodiverse habitats in the world that we have are on the reefs, we’re going to lost those systems undoubtedly I think by 2040/2050 we’ll be talking about corals reefs and how beautiful they were.”

 

 

 

Dr. Paul Butler – Honorary Senior Research Fellow

Profile

Paul’s research is in the field of sclerochronology, focusing in particular on the use of shells from long-lived bivalve molluscs to study the history of the marine environment. Essentially, these molluscs deposit annual increments in their shells (like rings on a tree stump). If a bivalve shell has a known date of death, a timeline of environmental variables can be investigated from that one shell, including seawater temperature and the origin of water masses. This can be of particular interest when studying climate change. Have a listen to the episode and take a look at Paul’s profile for more information.

 

 

Want to know more about sclerochronology and some intriguing clam facts? Sarah Holmes, PhD Researcher, wrote an excellent blog about this a few months ago, you can read it in full here.

Our longest chronology, which goes for 1300 years, is for waters of the north coast of Iceland… essentially we’ve got a temperature record… over the past 1000 years it shows a declining temperature up to about 150 years ago and then it shows a rapid increase

 

 

What is the IPCC?

The IPCC was established 30 years ago by the United Nations Environment Programme (UNEP) and the World Meteorological Organization (WMO) to provide a scientific view of climate change and its potential environmental and socio-economic impacts.

What is the IPCC Climate Change Report?

In December 2015 the Paris climate agreement was signed whereupon countries agreed that they would keep global temperatures “well below two degrees C above pre-industrial levels and to pursue efforts to limit the temperature increase even further to 1.5 degrees C”. The UN asked the IPCC to produce a special report to assess the feasibility of keeping global temperature rises to a maximum of 1.5C.

Scientists are nominated by governments and international institutions. In this particular report there we 91 lead authors from 40 countries which reviewed 6,000 references. This work is unpaid.

Where do we stand right now?

Currently we are on track to reach 1.5C warming between 2030 and 2052, and 3C by 2100.

If we hit just 2C warming, this could have serious impacts, here are just a handful:

  • Almost all coral reefs will be destroyed.
  • The arctic will have summers with no ice at least once a decade.
  • Huge numbers of animals and plants will become extinct.
  • Low-lying coastal regions, such as Bangladesh, will suffer from sea level rise.

 

“One of the key messages that comes out very strongly from this report is that we are already seeing the consequences of 1°C of global warming through more extreme weather, rising sea levels and diminishing Arctic sea ice, among other changes,” said Panmao Zhai, Co-Chair of IPCC Working Group I. – IPCC Press Release

Can we avoid this?

Yes, but we have just 12 years to turn it around and serious change is required. You can read more about that here.

The report finds that limiting global warming to 1.5°C would require “rapid and far-reaching” transitions in land, energy, industry, buildings, transport, and cities. Global net human-caused emissions of carbon dioxide (CO2) would need to fall by about 45 percent from 2010 levels by 2030, reaching ‘net zero’ around 2050. This means that any remaining emissions would need to be balanced by removing CO2 from the air.

“Limiting warming to 1.5°C is possible within the laws of chemistry and physics but doing so would require unprecedented changes,” said Jim Skea, Co-Chair of IPCC Working Group III. – IPCC Press Release
