The second session within the Marine and Antarctic Research Strategy research theme :  Oceans and marine ecosystems under global change was chaired  by Sandy Thomalla and Sarah Nicholson from Southern Ocean Carbon- Climate Observatory (SOCCO). The session title, “The Southern Ocean’s sensitivity to a changing climate:  insights from a seasonal cycle approach” were presented through oral presentations and e-posters from SOCCO.
