Channels and valleys on Mars
Mars Channel Working Group
1983, GSA Bulletin (94) 1035-1054
The discovery of channels, valleys, and related features of aqueous origin on Mars is of profound importance in comparative planetology. Models of the evolution of planetary surfaces and atmospheres must be reconciled with the diversity, abundance, and origins of channels and valleys on Mars. The term “channel” is properly restricted...
Atmospheric deposition: Sample handling, storage, and analytical procedures for chemical characterization of event-based samples in North Dakota
R. L. Houghton, Mary E. Berger, Nancy Zander, Sandra K. Dutchek
1983, Water-Resources Investigations Report 83-4205
The North Dakota atmospheric-deposition network uses HASL-type collectors to sample wet and dry deposition on an event basis for analysis of 8 principal mineral, 3 nutrient, and 15 trace constituents. Comparison of the compositions of wet deposition collected in adjacent collectors sampled on weekly and event bases indicates that weekly...
Eolian sand bodies of the world
E. D. McKee
1983, Developments in Sedimentology (38) 1-25
This chapter examines the eolian sand bodies of the world. Analyses regarding grain size and sorting distribution at Great Sand Dunes indicate that the higher dunes contain much more fine-grained sand and much less medium-grained sand than do the lower dunes, and, in addition, they are definitely better sorted. Cross-stratification...

A tale of two plutons: petrographic and mineralogic constraints on the petrogenesis of the Red Lake and Eagle Peak plutons, central Sierra Nevada, California
J.H. Noyes, D. R. Wones, F.A. Frey
1983, Journal of Geology (91) 353-379
The two plutons are similar in age (K/Ar, 87-89 m.y.) and range in composition from granodiorite to granite. The Red Lake pluton is equigranular, has a locally greisened marginal zone, and shows only minor mineralogical and chemical zoning, whereas the Eagle Peak pluton is mineralogically, compositionally and texturally zoned, with...
Heavy metal residues in prefledgling black-crowned night-herons from three Atlantic coast colonies
T. W. Custer, B.L. Mulhern
1983, Bulletin of Environmental Contamination and Toxicology (30) 178-185
Aquatic birds may serve as indicators of regional metal contamination. Because the food of prefledgling herons (Nycticorax nycticorax ) comes only from areas near the colony, their tissues should reflect local metal contamination. The authors' hypothesis was that prefledgling herons from the Rhode Island colony should have...
[Book review] Ducks, geese and swans of North America
Gary L. Krapu
1983, The Auk (100) 246-248
This is the 3rd edition of the classic work "The Ducks, Geese and Swans of North America," which was first published in December 1942.  The original edition was authored by Francis C. Kortright with color plates by T. M. Shortt. An authoritative reference on North American waterfowl for many years,...
Statistical evaluation of oil and gas prospects in the outer continental shelf of the U.S. Gulf Coast
J.C. Davis, J.W. Harbaugh
1983, Journal of the International Association for Mathematical Geology (15) 217
Areas of the U.S. Gulf Coast, both onshore and offshore, are among the petroliferous regions of the United States. In offshore Louisiana and Texas, most oil and gas is associated with structurally controlled traps on the crest or flanks of domes created by the diapiric movement of salt. These structures...
