Seabins of Styrofoam: Spending the Day with Fraser Riverkeeper at Granville Island

Hello world! I hope you've been doing well- fighting the fight against plastic pollution, and being a steward for the oceans and waterways! This past week I had my Birthday, and what better way to celebrate then to meet up with some of the Ocean Bridge Pacific Cohort and Fraser Riverkeeper/SwimDrinkFish at Granville Island to learn about 'The Seabin Project'!


What exactly is a Seabin you may ask? Great question! (I'm still learning about it myself so bear with me.) They look like a small garbage bin submerged in the water with a net in the center. The Seabin is hooked up to a power supply that filters surface water and therefore collects things like plastic wrapping, bottles, pellets, etc. from the water's surface.

We are very lucky to have three Seabins located in Granville Island! We collected each bin and spent the morning categorizing the varying samples collected. When taking a gross look at the bins, it looks as though they are filled with leaves and a few plastic wrappings. However, all is not what it seems from the surface! We started our categorization by separating any item that was larger than 3cm or so and weighing these items. We found large plastic fragments, bottle caps, wrappers, small plastic bags, etc. Our Seabin samples were then rinsed and run through a make-shift strainer which would collect small fragments of waste, and it was our job to go through the collected samples and categorize and count each small fragment.

Let me summarize this experience in three words: 'So. Much. Styrofoam'. I wish everyone could spend a day doing this, honestly. I think we don't realize how large fragments of plastic or styrofoam get broken down into these microparticles and dumped or fall in the waterways. We hear about it, yes. But speaking for myself, I'm a visual learner and seeing such a large volume of these tiny fragments collected from just one bin was a huge eye opener into the issue surrounding microplastics: and to think this was just surface waste collected. This is only the tip of the iceberg.

Overall we collected approximately 41 grams of small particle waste which contained styrofoam, plastic pellets, and misc. items such as calcium deposits and shells from our Seabin. I would like to send a special thank you to Imogen for walking us through the process and answering any of our questions. It was a great learning experience, and I recommend the next time you are out and about at Granville Island, head to the marina and see if you can spot the Seabins and what might be in them!
