The sea west of Spitsbergen; the oceanographic observations of the Isachsen Spitsbergen Expedition in 1910 . ° thanthat of Hjorts Stat. 64. 1 hisagrees fairly well with whatwas found above, viz. that thewater of the current in 19 iowas ° C. warmer than in1900, and C. warmer thanin section through Mohns Stats. 306,308, and 314 of July 21st and 22nd, 1878(Fig. 21, M 306, M 308, M 314) is in thesame region as Isachsens Sect.

The mean temperature of thewater between 50 and 450 metres inMohns section (Stats. 306, 308 and 314Iis ° C, and at Stats. 2, 3, and 4 ofIsachsens Section, C; if Stat. 5 be also taken itis C. As the observations at Isachsens stationswere taken 27 days earlier in the season than those atMohns stations, the mean temperature should be in-creased to ° C. in order to be comparable with thatof Mohns section. The waters of the current shouldaccordingly have been about ° C. colder in 1878than in 1910, in this 1912. No. 12. THE SEA WEST OF SPITSBERGEN. 33 Fig. 27. Mohns Stats. 283 and 308,of July 5th and21st, 1878 (seeFigs. 21, 26)are at aboutequal distancesrespectively north and south fromHjorts Stats. 63 and 64. Themean temperature of the formerstations is C, and that 01the latter C. As Mohnsstations were taken about 54 daysearlier in the season, their meantemperature should be increasedto °C. The current should consequently,in this region, have been C. warmer in1878 than in 1900. We found above that itshould have been C. colder in 1900 thanin 1910; if so, it should have been ° in 1878 than in 1910, while we foundabove that it was ° C. colder, a disagree-ment which is no greater than might be expected, consider-ing the very insufficient material of observations at ourdisposal.
