Satellite-derived sea surface temperature, in situ hydrography data, and satellite-tracked drifter data collected during winter 1979--1980 as part of the FRONTS 80 experiment are used to describe the spatial structure of the North Pacific subtropical front northeast of Hawaii. The satellite observations reveal a deformation scale meander (85 km¿32 km) in association with the front having an evolution time scale of ~60 days. The satellite measurements of the change in sea surface temperature across the front are typically 1¿C within a distance of 10 km. The correlation coefficients between the satellite data and the in situ hydrographic data were computed and found to be significantly nonzero above 800 m. The high correlation at deep levels indicates that the satellite was viewing a feature with sizable vertical extent, not just a surface phenomenon. Additionally, the hydrographic data and drifter trajectories were combined with the satellite-derived sea surface temperature data. Together they demonstrate that the feature observed by the satellite was nearly stationary during the experiment period. In addition, they also indicate that the flow along the front was nearly in geostrophic balance.
