This paper reports detailed in-water observations and satellite infrared images which are approimately coincident with a single Geosat altimeter track across the Iceland-Faeroes Frontal Zone. The ARE thermistor chain covered the upper 300 m of the ocean along the track, and the first two of a long sequence of NOAA satellite infrared images were obtained, all within 24 hours of the Geosat overpass. The data are interpreted as showing cold cross-frontal jets related to the formation of cold eddies wouth of the main frontal boundary. Implications for the use of altimetry for ocean monitoring are considered. ¿ American Geophysical Union 1990
