If you look at the microplastics that the students picked up during their practice, you can see that even if you just pull the net a little, you can still pick up plastic.
The amount of plastic this year is smaller than last year, but the sea area is slightly different from last year. Last year, the area was off Kushiro, just past Cape Erimo. There was a lot of litter. The reason might be that we sampled in the area where the Oyashio and Tsugaru Warm Current waters meet.
