| This paper deals with the hydrological regime and the water volume transport in the Faeroe-Shetland Channel in early summer of 1988 and 1989. The oceanographic conditions in the channel and in its vicinity are reviewed briefly. Then, some thermohaline and dynamical analyses are presented. The results are based on the vertical CTD soundings carried out during the cruises of R/V Oceania in the region of the channel in July 1988 and in July 1989. The upper part of the water column in the channel, down to the bottom of the main pycnocline, was warmer and more saline in 1988. However, the net transport of warm waters with theta greater-than-or-equal-to 3-degrees-C was oriented to the north, and was rather larger in 1989 (1.8 +/- 2.0 Sv) than in 1988 (1.0 +/-... |

| This study - carried out between the Elephant and the Orkney islands - showed that spatial variability in the marginal ice-edge zone (MIZ) was greater than that found in open sea. Salinity and silicate contents point to the existence of two fronts: the first - near Elephant Island - separates the Surface Antarctic Water coming from Drake Passage from the winter water originating in the Weddell Sea. This water is characterized by its high concentrations of nitrate (> 30 mu M) and silicates (> 80 mu M). The second front - near the South Orkney Islands undergoes the influence by a less saline water lens (< 34 %), poor in nutrients (N-NO3 < 24 mu M) and rich in chlorophyll (> 3.5 mg Chl a 1(-1)). Water masses circulation reveals the existence of... |
