Abstract:The Ross Ice Shelf is a floating ice mass about 200m thick over
an average depth along the barrier of 567 m. In January the prevailing wind blows.
from the east, parallel to the coast. The wind current transports the low salinity
layer (ca. 50 m) toward the ice shelf, where it must descend. Directly off the barrier
we find low salinities to a depth of 150 m. The circulation here is quite
similar to that defined by Sverdrup along the shelf ice of Queen Maud Land.
Because of sinking of the low salinity layer near the barrier, diatoms live in abundance
at subcompensation depths, Trigonium arcticum actually on the sea bed.
