| Zusammenfassung |
| A wind-driven, spatially coherent mode of nonseasonal,
depth-independent variability in the Canadian inland seas (i.e., the
collective of Hudson Bay, James Bay, and Foxe Basin) is identified
based on Gravity Recovery and Climate Experiment (GRACE) retrievals,
a tide-gauge record, and a barotropic model over 2003–2013. This
dominant mode of nonseasonal variability is correlated with the
North Atlantic Oscillation and is associated with net flows into and
out of the Canadian inland seas; the anomalous inflows and outflows,
which are reflected in mean sea level and bottom pressure changes, are
driven by wind stress anomalies over Hudson Strait, probably related
to wind setup, as well as over the northern North Atlantic Ocean,
possibly mediated by various wave mechanisms. The mode is also
associated with mass redistribution within the Canadian inland seas,
reflecting linear response to local wind stress variations under the
combined influences of rotation, gravity, and variable bottom
topography. Results exemplify the usefulness of GRACE for studying
regional ocean circulation and climate. |
