An ascent of Mt Erebus was made to the southwest crater rim to collect snow and sulphur samples and to observe the summits volcanic activity. On the ascent, temperature profiles were establish. Temperature and pressure values were recorded at Scott Base during the same time periods for comparison. The general features of the summit were described and volcanic activity was assessed. On the descent, lichen and soil samples were taken and 40lb of snow samples were collected at 5,500ft for analysis of sulphur fallout. A helicopter flight allowed large photographic coverage of the crater and environment, the identity and origin of the ice towers and the summit topography to be observed.
There were two investigators who chose to ascend Mt Erebus to make observations and collect samples for what is now the Institute of Geological and Nuclear Science (IGNS) and other investigators. From the reports, they are known simply as G. Lewis and G. Holdsworth. The location of any existing data is unknown and only one publication was found that was relevant to this data set. IGNS may have any existing data.
