Microcosms of marine plastic debris

Hello Foldscope Community, I am Mandy Barker a photographer from the UK who has been photographing marine plastic debris recovered from the world’s oceans for many years. The motivation for my work is to raise awareness about the vast amount of plastic entering our oceans, affecting ecosystems, biodiversity, marine life and ultimately ourselves.

Using the Foldscope I plan to look at microplastic particles taken from larger plastic objects that have been recovered from oceans around the world. I will also look at the current scientific concerns regarding microplastics entering the oceans in terms of microbeads and synthetic microfibres.

It is estimated that over 8 million tons of plastic enters the marine environment every year with 769 different species being affected. By 2050 scientists predict that 99% of seabirds will have been affected by plastic through ingestion and entanglement. Ingesting plastic can affect the endocrine system, reproductive system and function of creatures by absorbing toxic pollutants such a fertilizers, pesticides, flame retardants, PCBs (polychlorinated biphenyls) and DDT. Marine plastic acts as a sponge to absorb these industrial chemicals which are already present in the sea, they are then re-absorbed into the creature that has ingested it.

My first journey using the Foldscope is to recover and share with you all, plastic particles recovered from the North Atlantic Ocean.

Driving through the breathtaking volcanic landscape I am looking for a place to stop where the road meets the sea.

Pulling over I see a large object on the horizon and colours on the black larva, characteristic of yet another plastic strewn shoreline.

As I make my way towards the shore I see that people before me have made piles of plastic awaiting collection.

Macroplastic pieces litter the shoreline…

…and I realise that the object I saw from the road is a yacht that has been washed ashore, its surface now ironically covered with the graffiti of a bird’s jaw and skull.

But this time I am not so interested in larger plastic objects, it is the smaller plastic particles that are of more concern and of which I would like to view using the Foldscope.

I take various collections of recovered debris back to sort and make notes.

I categorise the plastic into type, and put some of the more brittle pieces into tubes.

degredation

Some of the plastic objects have degraded quicker than others and are crumbling leaving a fine powder residue on my fingers. These particles are what I will save  to look at under the Foldscope.

I was very excited to receive the Foldscope and perhaps a little daunted by the instructions, but they were very straight forward and I had no real problems.

Ready to go… now on to prepare the slides.

… and under the Foldscope – these powder sized – now enlarged particles, are especially detrimental when ingested by creatures and filter feeders at the base of the food chain.

Wow! this plastic fibre is the size of a hair!

Slide prepared to see what a ‘plastic bag for life’ recovered from the Celtic Sea, Ireland, looks like under the Foldscope.

The fibres and shapes aren’t regular as I had imagined but random and almost cell-like. Whilst these are inanimate pieces of plastic they almost take on the appearance of a nucleus or membrane created from the very material that can prove fatal for themselves.
