**1**5N-NMR INVESTIGATION OF HYDROXYLAMINE DERIVATIZED HUMIC SUBSTANCES.
Humic substances are the most abundant naturally occurring refactory organic compounds in soils and water. They have a broad range of physical, chemical and physiological properties. In soils, humic substances contribute to the cation exchange capacity, help maintain the physical structure, and play a role in plant growth and nutrition. In aquatic systems, humic substances serve to regulate the le

AIRBORNE INERTIAL SURVEYING USING LASER TRACKING AND PROFILING TECHNIQUES.
The U. S. Geological Survey through a contract with the Charles Stark Draper Laboratory has developed the Aerial Profiling of Terrain System. This is an airborne inertial surveying system designed to use a laser tracker to provide position and velocity updates, and a laser profiler to measure terrain elevations. The performance characteristics of the system are discussed with emphasis placed on th

Alaska goose populations: Past, present and future
Many people think Alaska remains a pristine wilderness and that wildlife populations are still at prehistoric levels. This very likely is not true for the 11 species and subspecies of geese that nest in Alaska. Large, widely dispersed populations of geese were observed near the turn of the century. Even in the early 1970s, it was estimated that Alaskan habitats were used by 915,000 nesting and 100

ANALYSIS OF STRONG-MOTION EARTHQUAKE RECORDS FROM A WELL-INSTRUMENTED EARTH DAM.
Strong-motion records from Long Valley Dam during the Mammoth Lakes earthquake sequence of May 1980 are analyzed to determine the main features of the dam's motions. The dam was instrumented with 22 accelerometers on its embankment and in the immediate vicinity, and more than 60 high-quality, long-duration accelerograms were recorded for the three largest earthquakes of the sequence. Free-field re

ANALYSIS OF THE U. S. GEOLOGICAL SURVEY STREAMGAGING NETWORK.
This paper summarizes the results from the first 3 years of a 5-year cost-effectiveness study of the U. S. Geological Survey streamgaging network. The objective of the study is to define and document the most cost-effective means of furnishing streamflow information. In the first step of this study, data uses were identified for 3,493 continuous-record stations currently being operated in 32 State
