Description:

Abstract:

An isostatic gravity map of Yukon Flats at a scale of 1:500,000 was prepared using all know publicly available gravity data. The data were gridded at 0.25 x 0.25 km interval and contoured at 5 mGal interval.
The principal facts (gravity measurements and supporting survey data) are provided along with the printable map.

Purpose:

This map was produced to examine gravity anomalies associated with sedimentary basins in the area.

Lineage:

Process_Step:

Process_Description:

The gravity data used to make this map were collected between 1959 and 1984. The data were collected by automobile, aircraft, and watercraft. Most of the data were collected as part of a U.S. Geological Survey (USGS) regional gravity data collection project. Some of the data were collected as part of other USGS local projects. One data set was collected by the NGS (National Geodetic Survey).
