A superb example of temperature and salinity finestructure in August 1976. Finestructure, although often less pronounced than this, was present at most outer domain stations. (From Coachman and Charnell 1979.) 1976, a year when the shelf was surveyed extensively, finestructure in the outer domain was reported in March (Coachman and Charnell 1977), in June (Kinder 1977), in August (Coachman and Charnell 1979), and in September-October (Kinder et al. 1978). Only a few stations with finestructure were reported outside the outer domain ( Kinder 1977, Fig. 22), and data from 1977 and 1978 also conform to these distributions. As Coachman and Charnell (1979) discussed, the finestructure occurs in the interior of the water column, below the surface mixed layer and above, the bottom mixed layer. Within this interior region, warmer and saltier oceanic water intrudes shoreward while cooler and fresher shelf water intrudes seaward. As interpreted by Coachman and Charnell (1977, 1979), the outer domain is a region of lateral (, cross-flow, and here also cross-isobath) water mass interaction with interleaving of water masses occurring at finestructure scales. Such interleaving, when water masses of similar density but differing temperature and salinity values mutually intrude, has been observed in many other locations (, see J. Geophys. Res. 83(C6) 1978). Occurrence of finestructure throughout the outer domain, best documented in 1976 (a year with extensive ice cover and late ice breakup) but also observed in 1977 and 1978, implies that finestructure is an inherent pairt of mixing across the outer domain. An essential stage in mixing large masses of water is the reduction of the spatial scale of identifiable water parcels, until a scale is eventually reached at which molec
