Table: 
Vertical Series of Temperatures, Salinities, and Densities taken at 
Amundsen’s Stations in Arctic Seas, April—August 1901. 
Explanation of Table II. 
rst Column. Number of Station, where the temperatures and water-samples were taken. 
2nd Column. Date and Locality of Station. IV indicates North Latitude. Z or W Longitude 
East or West of Greenwich. 
zrd Column. Hour at which the observations were taken. 
4th Column. Depth in Metres. A line under the figures indicates bottom. 
sth Column. Designation of the Thermometer used. Rg and Rro = Nansen Deep Sea 
Thermometers (from C. Richter) Nos. 109 and 110 (they were used with the Petters- 
son-Nansen Insulated Water-Bottle, see pp. 5 and 3). R 73 = Richter Reversing 
Thermometer No. 113 (see p. 3). Z 12 and Z 20 = Negretti and Zambra Reversing 
Thermometers Nos. 72012 and 72620 (see p. 4). The water-samples were taken 
with the small water-bottle of the writer's construction (mentioned p. 1) when the 
Reversing Thermometers R 13, Z 12 and Z 20 were used. 638 = Thermometer 
No. 638 (see p. 6) used for taking the temperatures with Amundsen's Water- 
Bottle (see p. 7). 
6th Column. Correct Temperature of the Water Strata 7 situ (referred to the Hydrogen 
Thermometer). The temperature-readings have been corrected for the instrumental 
errors; and those of the reversing thermometers also for the errors caused by the 
higher temperature of the broken off mercury, at the moment the reading was 
taken. 
7th Column. Permillage of Chlorine (Halogen) in Water-Samples, as determined by Titrations 
(Mohr), made by Mr. I. Leivestad. 
8th Column. Salinity (°/,,) computed from the Chlorine, by Knudsen’s Tables. 
gth Column. Density (ot) of Sea Water im situ, referred to a pressure of one atmo- 
sphere, and computed from Chlorine and Temperature by Knudsen’s Tables.
