The sea west of Spitsbergen; the oceanographic observations of the Isachsen Spitsbergen Expedition in 1910 . gh the observations made withthe Nansen-thermometer (marked with dots) and the lowerparts passing through the observations of the reversing thermo-meter (marked with crosses). The rise of temperature occurs at differentdepths of 300, 400, 500 or even 600 metres, always where the observationsof the reversing thermometer begin. There are obviously errors of Fig 4 Vertical of Sect. some kind in these series of obser- II. Readings of Nansen-thermometer are not vations, for with the salinities found,the temperature-readings of the Nan-sen-thermometer would make thedensities—at 150 metres at Stat. 13,at 200 m. at Stats. 4 and 5, at3oo Stats. 10 and 11, at 400 m. atStats. 3 and 8, and at 500 m. atStat. 6 — appreciably higher thanthose of the underlying strata, whosetemperature was determined by thereversing thermometer. Either thetemperature-readings of the reversingtheimometer must have been toohigh, or those of the Nansen-thermo-meter must have been too low. Om,. BJ0RN HELLAND-HANSEN AND HANSEN. Kl. Fig. 5.
