Planktic foraminifera from the southwestern Atlantic (30–60 S): species-specific patterns in the upper 50 m
E Boltovskoy, D Boltovskoy, N Correa… - Marine …, 1996 - Elsevier
Planktic foraminifers were studied in 96 samples collected in the southwestern Atlantic (30°–
60° S, along 53° W) in November 1993, mainly from depths between 0 and 50 m. Very high
proportions of juveniles (unidentified) were present throughout the area, especially north of
37° S, where they accounted for up to 70–80% of all shells recorded. For most species no
clear vertical specific stratification was detected in the 0–50 m layer. Zoogeographic
grouping of the 18 species identified allowed the defining of 5 distinct zones along the …
