Distribution map of Oncaea curvata by geographical zones
|
| | | | | |  Issued from : K.M. Swadling, So. Kawaguchi & G.W. Hosie in Deep-Sea Research II, 2010, 57. [p.898, Fig.6 (continued)].
Distribution of indicator species Oncaea curvata from the BROKE-West survey (southwest Indian Ocean) during January-February 2006.
Sampling with a RMT1 net (mesh aperture: 315 µm), oblque tow from the surface to 200 m.
The survey area was located predominantly within the seasonal ice zone, and in the month prior to the survey there was considerable ice coverage over the western section but none over the east.

Sampling depth (Antarct., sub-Antarct.) : 0-1000 m.
Vervoort (1951) puts doubts on the identifications done by C. B. Wilson (1942 a, p.198) for the Pacific.
This form can reach the north of the Antarctic convergence (45° S, 87° E).
