Vertical distribution, population structure and developmental characteristics of the less studied but globally distributed mesopelagic copepod Scaphocalanus magnus in the western Arctic Ocean

Scaphocalanus magnus is a large copepod species with a worldwide distribution. Information on the ecology of this species is scarce. In this study, S. magnus was collected using vertically stratified net sampling from an ice station in the western Arctic Ocean over a year. The vertical distribution differed between periods of polar night and midnight sun, with core depth distributions of 264–381 m for the polar night and 518–745 m for the...
