A Newly Digitised Ice-penetrating Radar Dataset Acquired over the Greenland Ice Sheet in 1971-1979

We present an ice-penetrating radar dataset acquired over the Greenland ice sheet by aircraft during the years 1971, 1972, 1974, 1978, and 1979. The dataset comprises over 177,000 km of flight lines and contains a wealth of information on the state of the Greenland ice sheet including information on ice thickness and englacial properties. During data collection in the 1970s, the data were recorded on optical film rolls and in this manuscript, we document the digitization of these film 5 rolls and their associated geographical information. Our digitization of the data enables interaction with and analysis of the data and facilitates comparison with modern-day radar observations. The complete dataset in full resolution with associated scanned notes is available here.
