Our primary #DFOscience research vessel for the #GreatLakesLaboratory, the CCGS Limnos, left this afternoon for an 8 day research and monitoring mission to support the #GreatLakes 🇨🇦🇺🇸 Cooperative Science and Monitoring Initiative #CSMI field year for #LakeOntario. This spring cruise is in collaboration with Environment and Climate Change Canada #ECCC, and we are collecting chemical, biological, and contaminants samples for many partners, including #EPA, #Cornell, and others. #plankton
