Themeridian of Makaroffs ^.0Gstation 33 was be-tween those of Stats. 3 and 4, and that of his Stat. 34 one degree morewesterly than Stat. 4 (see Fig. 211 The observations at all four stationswere taken in the first week of September of 1899 and 1910. Both Maka-roffs curves show much lower temperatures than those of Stats. 3 and 4,especially in depths of less than 400 metres. The mean temperature of the water between 50 and 450 metres atMakaroffs two stations was C. while the corresponding mean tempera-ture for Stats. 3 and 4 was ° C. If these temperatures were compar-able, the Atlantic water should thus have been about C. colder in 1899 than in 1910.
