Bottom features and processes related to drifting ice on the Arctic shelf, Alaska Bottom features and processes related to drifting ice on the Arctic shelf, Alaska
Early investigations of artic shelf regions led to the hypothesis that certain micro-relief forms are related to the action of grounded ice (for example, Rex, 1955). Since the introduction of side-scan sonar as a tool for ocean-floor surveys, a number of workers have described the occurrence of linear bottom features produced by grounded ice. Such features have been found on modern polar...
Climatic factors related to land-use planning in the Puget Sound basin, Washington Climatic factors related to land-use planning in the Puget Sound basin, Washington
Climate is a basic part of the natural environment and exerts a strong influence on many of man's activities. In the Puget Sound basin especially, effective land-use planning requires consideration of climatic influences, for the climate differs significantly in the various parts of the area. However, climatic information may not be given adequate consideration in the planning process if...

Contour map of the bedrock surface, Ludlow Quadrangle, Massachusetts Contour map of the bedrock surface, Ludlow Quadrangle, Massachusetts
Contours show the altitude of the bedrock surface. The position of the contours is based largely on data from wells and test holes supplemented by knowledge of the geologic history of the region. The map show the configuration of the bedrock surface if all unconsolidated earth materials were removed.
