The Continuous Plankton Recorder in the Southern Ocean: a comparative analysis of zooplankton communities sampled by the CPR and vertical net hauls along 140°E
deployed on the northern leg (average sampling depth = 10.5 m). Both net systems were harnessed with 270?m ... patterns. Species richness and diversity increased with depth, and were lowest for CPR samples. Conversely ... , dominance decreased with depth and was highest for CPR samples. Evenness was similar for all sample groups ... to its shallow towing depth, the CPR focuses on species with surface distributions. Despite under ...
