We have created a readily accessible, standardised and quality checked IMMA-compliant dataset of meteorological observations from the Southern Ocean. Each record contains a number of positional, meteorological and meta-data parameters found in the Christian Salvesen Co. whaling logbooks of the 1930s and 1950s. All data points were passed through statistical tests to flag and correct erroneous values. The dataset is made available in csv file format. For further details on the field naming conventions, units and codes of various parameters, please see IMMA report (http://icoads.noaa.gov/e-doc/imma/R3.0-imma1_short.pdf)
