Abstract
Complex temperature anomalies observed near Arctic
ice margins in the Chukchi Sea were found to be associated
with the interaction of the warm coastal current with the
ice cover and resident bottom water. These anomalies were
characterized by large temperature gradients found in areas
of very low density gradient. They were in the form of
inversions, interleavings , and discrete parcels which varied
greatly in short distances. The processes which produced
mesostructure were directly linked to the presence of ice
and were found to affect the entire water column. Structure
was found in the vicinity of the ice margin but was observed
to dissipate well inside the ice margin. A dynamic high was
found which was related to the melting of ice and characteristically
occurred in the melting zone of the ice margin.
This dynamic high was limited to a depth of 10 meters and
is believed to be a factor in the deepening of mesostructure
elements and other phenomena as they pass the ice margin
with the current.
