Prudhoe Bay Cumulative Impact Map A: Raynolds 2014

Aga prudhoe a human disturbance 2010 Alaska Geobotany Center (AGC) - Map A of the historical infrastructure changes for the Prudhoe Bay Oilfield for 10 dates from the initial oil discovery in 1968–2011. Aerial photos taken in 1949 and 1968 were used to define the geobotanical characteristics prior to development. Infrastructure changes were digitized from each successive analysis year (1970, 1972, 1973, 1977, 1979, 1983, 1990, 2001, and 2010). Polygon fields...
