Vertical distribution of Calanus hyperboreus in the central Arctic Ocean1
The vertical distribution of Culanus hyperboreus was determined for a 23‐month period from net samples collected from T‐3 Ice Island in the central Arctic Ocean. Distributions of copepodite stages were similar, but dissimilar to that of the adults. The depth range of the copepodites was 300–500 m, e...

| Summary: | The vertical distribution of Culanus hyperboreus was determined for a 23‐month period from net samples collected from T‐3 Ice Island in the central Arctic Ocean. Distributions of copepodite stages were similar, but dissimilar to that of the adults. The depth range of the copepodites was 300–500 m, except during summer when they rise to the surface. The adult female population sank gradually from 100 to 300 m in the spring. During summer, females were at the surface and by fall they were centered at about 150 m, where they remained throughout winter. Adult males were centered deeper (400–700 m) than the females and were present only during spring and early summer. Calanus hyperhoreus appears to have a generation length of at least 3 years in the central Arctic Ocean. |
