| Zusammenfassung |
| We perform a statistical analysis of temperature and velocity fields in Fram Strait, the deepest
passage between the Arctic Ocean and the North Atlantic. Time series of velocity and
temperature exist for an array of moored instruments across the gateway at 78.8°N since
1997.
Our analysis reveals a strong variability of both parameters on different time scales. Since
the spatial resolution of moorings is coarser than the local Rosby radius, the array
does not resolve mesoscale motion like eddies. Correlations between neighbouring
instruments are relatively high in vertical and significantly lower in the horizontal
direction. The higher vertical correlation for current velocity between instruments at
single moorings, particularly in the West Spitsbergen Current, reflected a prevailing
barotropic structure of the flow. The higher horizontal correlations in the central part of
the strait on longer time scales can be linked to the Atlantic water recirculation. |
