ARCTIC Baffin Island Fjord Macrobenthos: Bottom Communities and Environmental Significance’
ABSTRACT. Cluster analysis of the benthos from ten Baffin Island fjords defines six faunal associations. The macrotidal Sunneshine Fiord has a shallow kelp-related Isopod Association. Cambridge Fiord supports a shallow Onuphid Association controlled by gravel from dropstones. A widespread Portlandia...
