THERMAL-INERTIA MAPPING IN VEGETATED TERRAIN FROM HEAT CAPACITY MAPPING MISSION SATELLITE DATA. THERMAL-INERTIA MAPPING IN VEGETATED TERRAIN FROM HEAT CAPACITY MAPPING MISSION SATELLITE DATA.
Thermal-inertia data, derived from the Heat Capacity Mapping Mission (HCMM) satellite, were analyzed in areas of varying amounts of vegetation cover. Thermal differences which appear to correlate with lithologic differences have been observed previously in areas of substantial vegetation cover. However, the energy exchange occurring within the canopy is much more complex than that used...

TOPOLOGICAL STRUCTURING OF RASTER-SCANNED LINE MAP DATA. TOPOLOGICAL STRUCTURING OF RASTER-SCANNED LINE MAP DATA.
The U. S. Geological Survey has a requirement for the collection of large amounts of digital map data from existing graphic map separates. Prototype production techniques have been developed to capture line data from the map separates using a raster-scanning input device. After minimal editing in raster form, the data are converted to 'unstructured' vector form. In order to be processed...

U. S. GEOLOGICAL SURVEY ALASKAN GOLD PROJECT. U. S. GEOLOGICAL SURVEY ALASKAN GOLD PROJECT.
The United States Geological Survey has begun a state-wide study of Alaskan gold deposits. The immediate goals are to determine the relationship of gold in placer deposits to possible primary sources, to determine how nuggets form, to contribute to existing knowledge of principles for prospecting for placer deposits, and determine if minerals associated with placer deposits might suggest...

U. S. GEOLOGICAL SURVEY MARINE-MINERALS RESEARCH. U. S. GEOLOGICAL SURVEY MARINE-MINERALS RESEARCH.
Summary form only given. The US Exclusive Economic Zone is an area approximately one and two-thirds the size of the land area of the United States. In this frontier area, US Geological Survey (USGS) research in marine minerals is aimed at three objectives: (1) defining geologic settings of potential mineral resources; (2) understanding the processes by which seafloor nonliving resources...

U. S. GEOLOGICAL SURVEY'S RESEARCH PROGRAM IN THE NEWLY PROCLAIMED EXCLUSIVE ECONOMIC ZONE. U. S. GEOLOGICAL SURVEY'S RESEARCH PROGRAM IN THE NEWLY PROCLAIMED EXCLUSIVE ECONOMIC ZONE.
The U. S. Geological Survey (USGS) has been developing a program which would emphasize broad-scale surveys of the continental margin and intensive studies of 'baseline corridors' in various areas of the U. S. EEZ to gather energy and mining information in this new frontier as quickly as possible. Of twelve baseline corridors identified to date along the east and west coasts and the Gulf...

VERTICAL MOVEMENT OF GROUND WATER UNDER A LANDFILL, ANCHORAGE, ALASKA. VERTICAL MOVEMENT OF GROUND WATER UNDER A LANDFILL, ANCHORAGE, ALASKA.
A thorough review of existing ground-water information may, in some cases, be adequate to estimate rates of migration of pollutants. Analysis of data from well-performance tests and from hydrologic-data stations near a landfill in Anchorage, Alaska, indicates that pollutants migrating downward toward a confined aquifer that supplies water to three municipal wells near the landfill do not...

An extensive data base for cobalt-rich ferromanganese crusts from the world oceans An extensive data base for cobalt-rich ferromanganese crusts from the world oceans
A new database for ferromanganese crusts from the world oceans is being compiled by the U.S. Geological Survey. Crusts differ from abyssal nodules by forming principally on steeper, raised areas or current-swept plateaus in the oceans. Some crusts contain relatively large concentrations of cobalt (1.0%) in areas within national territorial jurisdictions.
