| Abstract | Between the years 1927 and 1952 inclusive, more or less systematic temperature and salinity observations on two roughly parallel hydrographic cross-sections of the Faroe-Shetland Channel have revealed certain fluctuations, both dynamic and characteristic, which exemplify the phenomenon of marine climatic change. Except perhaps in 1947, the Atlantic Current through the Channel evidently flowed more strongly in the autumn-winter than in the spring-summer seasons of the period from 1946 to 1952, and these autumnal-winter intensities themselves apparently increased in magnitude to a maximum in December 1951 . In the fourth decade, the oceanic water-mass in the Channel was infused with extra-Mediterranean water which has not appeared, save sporadically in isolated trace in the years before or since, and which from small beginnings in 1930-1931 showed maximum concentration in 1933 1934 and thereafter waned to extinction in 1938-1939. Similar circumstances marked the appearance of first one, and then two, types of Arctic water-mass in the bottom layers of the Channel in the latter years of the fifth and the first years of the sixth decades. |
