2.5 nm that any patterns smaller than about 9 km can be biased methodically.
Presented observations from the M-8 eld campaign however show that the detected mesoscale
patterns are vertically coherent over larger spatial scales. These phenomena probably result
from dierent processes acting on dierent spatiotemporal scales. It may be speculated that
intrusions, which have been initially coherent over larger spatial scales were, at this late-stage
of the inow, already distorted by the strain eld of mesoscale motions. The σ θ contours in
Fig. 3.5 b suggest that there were a few eddies in and below the halocline during M-8. For
