| The present study defines new interpolation functions for hydrological data. These functions are applied to generate climatological maps of temperature-salinity distribution with a 25 m depth interval and a 30 km space interval (MEDTRANS data set). The data undergo rigorous initial data quality control, having passed several filtering procedures. The gridding is done on neutral density surfaces, which allows better representation of thermohaline fronts for the same gridding radius. The multi-pass Barnes optimum interpolation procedure with spatially variable size of the gridding window is used. The shape of the window accounts for the dominant along-isobath direction of water mass transport over steeply sloping topography. A local ratio of topographic to... |

| We use cross-slope sections of direct current observations together with a high resolution numerical simulation to revisit estimates of transports and entrainment in the Gulf of Cadiz. We provide a three dimensional picture of the outflow from the Mediterranean into the intermediate layers of the Atlantic. In the model, the time-averaged Mediterranean Undercurrent is characterised by two cores of zonal velocity at 8°30′8°30′W: one at 500 m (in the σ1σ1 interval 31.6-31.831.6-31.8 kg m-3) and another around 1100 m (∼32.2∼32.2 kg m-3) with maximum westward velocity of 0.36 m s-1. A single well defined vein of saltier and warmer water (salinity maximum ∼36.9∼36.9 psu, 1 psu = 1 kg salt/1000 kg seawater) is found attached to the slope, centred at 1300 m... |
