A school cruise was organised by NIVA on 26th of April 2023 in collaboration with the Inspiria Science Center at the Outer Oslofjorden along with students from Jessheim High School. The students were lectured about marine litter in Oslofjorden and they were instructed how to use the Manta trawl onboard to collect microplastic particles for quantitative analysis. In addition, the students used a soft bottom trawl in order to collect bigger marine litter items. The students learned how to use the smartphone plastic NIR scanner developed within Nautilos project to identify the bigger plastic items.
