Yukon Seismic Survey Lines From 1960s To Present

Pre-1999 seismic line data, obtained from the National Energy Board as point coordinates with basic information, includes surveys from the 1960s and 1970s recorded in the NAD27 datum. Starting in 1999, location data is provided by exploration companies to the Government of Yukon as part of statutory reporting. The dataset is distributed via GeoYukon and contains coordinates for seismic lines used in oil and gas exploration.

Use Cases

• Map seismic line density over time using coordinate point data to analyze exploration intensity.
• Identify potential location errors by comparing NAD27 and NAD83 datum coordinates for historical surveys.
• Analyze the spatial distribution of oil and gas exploration activities from the 1960s onward using the provided line data.

Strengths

• Includes historical survey data from the 1960s and 1970s, providing a multi-decade temporal record.
• Post-1999 data is sourced directly from exploration companies via statutory reporting, ensuring a formal collection method.
• Distributed through the authoritative GeoYukon platform by the Government of Yukon.

Limitations

• Pre-1999 data from the National Energy Board is noted as not comprehensive and contains known location errors due to datum issues.
• Some historical coordinate data recorded in NAD27 was not converted to the current NAD83 standard, resulting in positional inaccuracies.
