Abstract

The fine structure of oxygen in some regions of the north-eastern Atlantic has been studied. A discrete-continuous inflow of the Mediterranean intermediate water has a strong effect on the O2 distribution in the layer of the main minimum of oxygen concentration. In general, this layer tends to increase and become more oxygenated when the mean vertical gradients of the oxygen concentration become smaller. Lenses of intrusion and inversion of the seawater with a high O2 content are observed in the layer. Passage of the lens in the layer of the main minimum of oxygen concentration induces vertical advection of waters and a decrease of the oxygen concentration above and below the lens within 500–700 m.
