The water bounding such a current to the west as shown by the offshore stations has a higher oxygen content which can be ascribed to water of the type shown by the ' Meteor' southern stations. 20- Z ID- S'.

Temperature and oxygen in the layer of minimum oxygen at selected stations of the 'Meteor' expedition, to the north and south of the area surveyed by the 'William Scoresby'. The positions and dates of these stations are given in Table 10. With subsequent upwelling it might be expected that the water uplifted to the surface would be heavily depleted in dissolved oxygen and this the more so the farther north in the region. The presence of this water on the continental shelf would accentuate the effects of local decomposition of organic matter on the sea-bed, and consequently the depletion of oxygen would become more accentuated towards the coast on the continental shelf. This proceeds to such an extent that anaerobic conditions are created on the sea-bed (p. 204). Tabh 10.
