Notes: Trace number is that given in the SEG-Y data trace headers; all distances refer to source-receiver midpoint locations. Northing and Easting is the distance north and east, respectively, from Site 883F (Surveys 1203 and 1204, Farnella data; 51.1984°N, 167.7681°E), Site 1205 (Survey 1205; 41.33332°N, 170.37833°E), and Site 1206 (Survey 1206; 34.92580°N, 172.14588°E). Distance refers to along-line distance from the start of survey.
