Geologic map of the south-central Sagavanirktok Quadrangle, North Slope, Alaska

This geologic map and report present 1:63,360-scale geologic mapping of the south-central Sagavanirktok Quadrangle in northern Alaska. This area encompasses approximately 600 square miles in the northern foothills of the Brooks Range, and includes stratigraphic and structural elements important to understanding the oil and gas potential of Alaska's North Slope.

Geologic Provinces of the Circum-Arctic, 2008 (north of the Arctic Circle)

This shapefile includes arcs and polygons that describe U.S. Geological Survey defined 33 geologic provinces of the Circum-Arctic (north of the Arctic Circle). Each province has a set of geologic characteristics distinguishing it from surrounding provinces. These characteristics may include the dominant lithologies, the age of the strata, and the structural style. Some provinces include multiple genetically-related basins. Resource-assessments are conducted by research scientists of the U.S Geological Survey's World Petroleum Resource Project by means of a combination of Total Petroleum System analysis based on available geologic information, and statistical analysis of production and exploration information. Total...

Circum-Arctic Resource Appraisal (north of the Arctic Circle) Assessment Units

The Assessment Unit is the fundamental unit used in the World Petroleum Resources Project. The Assessment Unit is defined within the context of the higher-level Total Petroleum System. The Assessment Unit is shown here as a geographic boundary interpreted, defined, and mapped by the geologist responsible for the province and incorporates a set of known or postulated oil and (or) gas accumulations sharing similar geologic, geographic, and temporal properties within the Total Petroleum System, such as source rock, timing, migration pathways, trapping mechanism, and hydrocarbon type. The Assessment Unit boundary is defined geologically as the limits of the geologic elements that define the Assessment Unit, such as...

Vegetation Type Hierarchies and Landform Disturbance in Arctic Alaska and Alpine Colorado with Emphasis on Snowpatches

Four-level Braun-Blanquet vegetation type hierarchies of an arctic (a section of the Arctic Coastal Plain at Atkasook, Alaska) and an alpine (Indian Peaks area, Colorado Southern Rocky Mountains) area were compared through their vascular plant taxa composition. Vegetation types at all hierarchy levels were more numerous, less well defined, and less clearly distributed along the controlling environmental gradients in the Arctic than in the alpine. This greater environmental and vegetational heterogeneity and relatively poor definition of vegetation types are probably controlled by the surface disturbances of the thaw-lake cycle, rivers, cryoturbation, and wind, which cause significant horizontal movement of materials...
