| Summary: | The periodic collection of hydrophysical data along the northern Norwegian coast (from Malangen to Porsangerfjord) started in the beginning of the 20th century and some of the oldest stations are still in operation by the “Havmiljødata” sampling programme organized by UIT-The Arctic university of Tromsø. Systematical retrieval of the physical oceanographical data during shorter periods (1–2 years) in Tromsø and north Norway goes back to ca. 1872 when Tromsø Museum was founded. The first decades sampling was performed with hired vessels, and retrieval of hydrophysical data was connected to sampling of marine organisms. During the first decades of the existence of the Museum up till ca. 1922, temperature and salinity data were during periods collected from areas adjacent to Tromsø, again as data to back up biological observations (Soot-Ryen, 1932a). Large parts of these data sets was stored at Tromsø Museum in the form of hand-written tables, or the data sets have been published in table form merely, i.e. without any kind of interpretations attached (Soot-Ryen, 1932b, 1943).The sampling frequency increased when Tromsø Museum in 1926 got their first research vessel with hydrographic winch and water bottle systems (Soot-Ryen, 1938). This vessel was used until the start of WW2.The present work, representing the period 1923-1950, are from the former mentioned reports and old handwritten tables (that we have digitized).
