ABSTRACT:
Measurements of the circulation of Lake Superior have traditionally been
limited in space and time and our knowledge of its patterns has been
sketchy. New measurements of time series of currents from the Keweenaw
Current and observations of currents and near-surface temperature fields
from central Lake Superior will be presented. These observations indicate
the importance of a large-scale wind-driven flow which is responsible for a
significant fraction of stirring open-lake and coastal waters. In addition,
a persistent eddy field is present in all regions of the lake. These eddies
suggest new ideas regarding vertical and horizontal transport mechanisms
within large lakes and challenge ideas regarding thermohaline compensation
in the upper ocean.
