| A 12-yearlong thermosalinograph data set from ships of opportunity was used to make an extensive study of meso-scale surface fronts in the western part of the North Atlantic subpolar gyre from 1997 to 2009. Fronts are identified on a sea-surface-salinity/sea surface temperature gradient criterion with a typical width of 20 to 60 km. The seasonal hydrographic properties of fronts are investigated. We find that, whereas salinity jumps across fronts are close to the larger scale variations, the temperature jumps across fronts are often smaller than the larger scale variations, in particular in summer-time. We also find in June vertical profiles that the relative weight of temperature over salinity in the density jump across fronts is smaller at the surface... |
