Temperatur, Salzgehalt und Dichte an der Oberfläche des atlantischen Ozeans

Abstract

THE temperatures on which this work is founded were observed for the larger part by merchant ships. A very large proportion were collected and partly worked up by the Royal Netherlands Meteorological Institute ; the Danish Meteorological Institute, the German Seewarte and the charts published by the Meteorological Office in London with the reports of various expeditions were the sources of other material. For the area from 50° N. to the Antarctic, about 1,400,000 observations were used. The observations of salinity available were so few that it was necessary to use the earlier ones made with the hydrometer ; a table of sources gives the method by which they were reduced to modern standards. This table contains 176 entries, some of which cover many ships, and should be useful for reference. The chief table gives the mean temperature and salinity for each month and one-degree square.
