Characterization of an Arctic kelp community at Kongsfjorden/Spitsbergen in times of global change.
According to diverse model predictions Arctic seaweed systems are proposed to alter structure and composition due to global change in future. Two major factors that will influence these systems are (1) ocean warming and (2) increased glacier melting leading to a reduction in ice cover and ice-scouri...
