The sea west of Spitsbergen; the oceanographic observations of the Isachsen Spitsbergen Expedition in 1910 . n-thermometer, notconsidering small irregularities that may arise fromin accuracies of the observations, and also from themovements of the ship and the water, as the surface-observations being not always taken exactly on thesame spot or in the same hour as the observationsof the water at 20 metres. this manner the surface-observations afford apossibility of finding a probable upper limit of thecorrection of the readings of the Nansen-thermometerin June, 1910, while the observations with the revers-ing thermometer, combined with the salinities, givethe lower limit of the same correction. By taking themeans of the values thus found at each station, we have cometo the conclusion that the readings of the Nansen-thermometershould be corrected by about -t- ° C. at all stations of June25th to 28th (1. e. Stats. 1 —14). When the readings have beenthus corrected we obtain very probable values both of tempera-ture and density. That the vertical temperature-curves thus obtained have very. 1Soo 2000 i 1912. No. 12. THE SEA WEST OF SPITSBERGEN. II Fig. 14. Curves of IS 10 28000- prSE^^ Fig. 15.
