Abstract Using 111 shipboard hydrographic sections across Denmark Strait occupied between 1990 and 2012, we characterize the mean conditions at sill, quantify water mass constituents, describe dominant features of Overflow Water (DSOW). The vertical temperature, salinity, density reveal presence circulation components found upstream in particular shelfbreak East Greenland Current (EGC) separated EGC. These correspond to fronts consistent with surface‐intensified southward flow. Deeper column...
Shipboard hydrographic and velocity sections are used to quantify aspects of the North Icelandic Jet (NIJ), which transports dense overflow water Denmark Strait, Irminger Current (NIIC), imports Atlantic Iceland Sea.The mean two currents comparable, in line with previous notions that there is a local overturning cell Sea transforms water.As NIJ NIIC flow along north side Iceland, they appear share common front when bottom topography steers them close together, but even separate poleward...
Abstract Time series data from a mooring in the center of Denmark Strait and collection shipboard hydrographic sections occupied across sill are used to elucidate mesoscale variability dense overflow water strait. Two dominant, reoccurring features identified that referred as bolus pulse. A is large, weakly stratified lens associated with cyclonic rotation modest increase along-stream speed 0.1 m s −1 . When passes through strait interface height layer increases by 60 m, bottom temperature...
Abstract Initial results are presented from a yearlong, high-resolution (~2 km) numerical simulation covering the east Greenland shelf and Iceland Irminger Seas. The model hydrography circulation in vicinity of Denmark Strait show good agreement with available observational datasets. This study focuses on variability overflow (DSO) by detecting characterizing boluses pulses, which two dominant mesoscale features strait. authors estimate that yearly mean southward volume flux DSO is about 30%...
Abstract A high-resolution numerical model, together with in situ and satellite observations, is used to explore the nature dynamics of dominant high-frequency (from one day week) variability Denmark Strait. Mooring measurements center strait reveal that warm water “flooding events” occur, whereby North Icelandic Irminger Current (NIIC) propagates offshore advects subtropical-origin northward through deepest part sill. Two other types mesoscale processes Strait have been described previously...
