From the warming of the dye patch, 1.9×10<sup>−6</sup> and 7.6×10<sup>−6</sup> °C/s on the south flank and northeast peak, respectively, as it passed through the frontal temperature gradient, we infer a mean on-bank flow of 1.6 cm/s on the south flank and 3.1 cm/s on the northeast peak. The heat flux required for this warming is predominantly due to vertical mixing within the tidal front. From the dispersion of the dye patch, we estimate a vertical diffusivity of 1.6 and 3.1×10<sup>−3</sup> m2/s and a cross-front diffusivity of 18 and 30 m2/s on the south flank and northeast peak, respectively. The evolution of a second dye injection on the south flank was distinctly different from the first because of the proximity of the foot of shelfbreak front now displaced onto the bank by a transient meander to within 6 km of the tidal front. Although the dispersion of this patch was the same as for the first injection, its cross-bank displacement was much less reflecting the divergence of the cross-bank flow in this region.","AbstractOtherLang":null,"BibLvlCode":"AS","StandardTitle":"Diapycnal flow through a tidal front: a dye tracer study on Georges Bank","OrigTitleLangCode":"en","OrigTitleLangCodeExtended":"eng","OrigTitleLangID":15,"DateLastModified":{"date":"2025-07-02 08:33:14.980000","timezone_type":1,"timezone":"+00:00"},"UserAccessRight":null,"UserAccID":null,"AuthorKeywords":"diapycnal flow; dye tracer; tidal front","OtherDescriptors":null,"Notes":null,"AnaPub":2002,"MonPub":null,"DateUpdate":"2018-05-17","DateCreate":"2004-05-26","SecASFANote":null,"ConfID":null,"PeerRev":1,"VlizCoreFlag":1,"WoScode":"WOS:000179377800004","VABBcode":null,"OpenAcc":1,"DOI":"10.1016/s0924-7963(02)00194-x"},"refs":null,"anarec":{"AnaID":62120,"PubliDate":2002,"Pagination":"31-46","XtraPublOfAnaID":null,"ISBN":null,"Volume":"37","Issue":"1-2","BRefMon":null,"BRefMonRR":null,"BRefXtra":null,"BRefXtraRR":null,"SerBRefID":43079,"SerRR":"Journal of Marine Systems.
