Abundance and size measurements of calanoid copepods in the subtropical South Atlantic Ocean during POLARSTERN cruise PS81 (ANT-XXIX/1) ...
Abundance and community structure of calanoid copepods of one day (stn. 16; bottom depth 5,433 m) and one night station (stn. 15; bottom depth 5,462 m) were analyzed (Fig. 1). Stratified vertical hauls were carried out within 24 h with a HydroBios Multinet Maxi (0.5 m2 net opening, 9 nets, 150 µm me...

| Summary: | Abundance and community structure of calanoid copepods of one day (stn. 16; bottom depth 5,433 m) and one night station (stn. 15; bottom depth 5,462 m) were analyzed (Fig. 1). Stratified vertical hauls were carried out within 24 h with a HydroBios Multinet Maxi (0.5 m2 net opening, 9 nets, 150 µm mesh size) from 800 m depth to the surface (strata: 800-700-600-500-400-300-200-100-50-0 m). The filtered water volume was measured with a flowmeter attached to the net opening. After retrieval, samples were preserved in a 4% borax-buffered formaldehyde in seawater solution. Calanoid copepods were sorted according to their developmental stages (copepodids C1-3 and C4/5, adult females and males), counted and identified to genus or, if possible, to species level under a dissecting microscope (Leica MZ12). Rare species (<100 individuals per sample) were counted from the entire sample. Total length (TL) of up to 100 calanoid individuals per taxonomic category (i.e. family/genus/species) and stage was measured (~6,600 ... |
