Meteorological Observations At Heard Island, 1971

As part of the expedition to Heard Island in 1971, meteorological observations were made and recorded four times a day (0000, 0600, 1200 and 1800 local time). The air pressure, pressure trend, wind speed and direction, temperature, relative humidity, cloud cover, visibility, minimum and maximum daily temperatures as well as general notes on the weather were all recorded in a log book. Notes on the instrument calibrations were also recorded. The physical log books are archived in the records store at the Australian Antarctic Division.
