Jessika Hagberg (Örebro University) and Louise Hedenskog (Thorén Business School, Örebro) throw the manta trawl in the water between Sweden and Germany in the southern part of the Baltic Sea. This excercise is repeated twice a day and trawling takes an hour each time most days of the expedition.
Read MoreFor the first trawl, the Manta went in by a ten point throw by Bert and Jonas, and the rest helped get organized for the remaining sampling using the pump and the bucket. When the pump was in the water, we where thrilled to get 15 minutes for a swim off the boat. It was absolutely fantastic!!!

The calm, clear skies made trawl deployment and recovery very easy. The weather, in conjunction with the ease of deployment, was welcomed by the very wary crew! The only ‘problem’ we had at one point was a pesky Cahow trying to investigate the equipent and whether or not he could make a tasty meal out of it.

As our eyes began to adjust even more to the night sky, we were able to pick out more and more aspects that only being on the ocean in the dead of night would present. The waves crashed against the bow, and we created a wake as we travelled further south. It excited some of the smallest marine organisms called plankton, causing them to illuminate and dance in the sea beneath us.

Being able to see the moon, the stars, and planets was breathtaking, and certainly not something we see everyday. There was also enough wind at the time to allow for straight sailing. As a result, we were able to turn off the boat engine and have the waves be the background soundtrack for our watch. We were also treated to a beautiful sunrise, painting the sky various hues of pink, orange, red and blue.

Early observations of the samples show that most of the plastic and debris was being found in the top three nets, so approximately the first meter of the water column. Julia, the scientist spearheading this project, has her work cut out for her as she analyses the information collected. Once the two trawls were completed for the day, it was time for lunch – quesadillas or Casey-dillas, as they were renamed by Casey.

We’ve got a mix of 13 crew members from all over, including the UK, Holland, United States, Brazil, Sweden, and one person all the way from Bermuda! We spent the larger part of the morning assembling our multi-level trawl, which is paramount in collecting any plastic debris. It collects debris at various levels to create a depth profile of plastics within the gyre.

I’m currently preparing for another night shift, and reflecting on my experiences of the past few days. After successfully testing the multi-level trawl in a Bermudian harbour a week ago, we then spent three days enduring 10ft swells, 30kt winds and the aftertaste of seasickness medication. The sound of flopping […]
