The GREENEDGE project was dedicated to the study of the spring bloom development in the Baffin Bay and at an ice camp site based in Qikiqtarjuaq. Samples were collected over 3 months in 2016 both at the ice camp below ice and during a sea cruise on board the canadian ice-breaker Amundsen. Samples were observed in lugol fixed samples at the laboratory and in SEM on a Phenom Pro (courtesy of D. Vaulot and I. Probert). Both sea-ice and planktonic species were observed.
