Interactions between seabirds and fisheries in the North Pacific Ocean Interactions between seabirds and fisheries in the North Pacific Ocean
Interactions between commercial fisheries and seabirds in the northern Pacific Ocean are increasing with rising consumption of fishery products. As fishing expands into remote areas previously not fished, additional populations of seabirds may be affected. Some interactions such as introduction of fish processing wastes into the environment may be beneficial for seabirds, while others...

Fall migration of Ross' Gull (Rhodostethia rosea) in Alaskan Chukchi and Beaufort seas: Final report Fall migration of Ross' Gull (Rhodostethia rosea) in Alaskan Chukchi and Beaufort seas: Final report
Ross’ Gulls (Rhodostethia rosea) are a major component of the pelagic avifauna of the Alaskan Chukchi and Beaufort seas in fall. Until recently, however, their distribution, abundance, and phenology of occurrence in Alaskan waters was poorly known. Since 1970, a combination of shipboard, aerial, and land-based surveys has revealed the major features of this species’ post-breeding...

Sandstone petrographic evidence and the Chugach-Prince William terrane boundary in southern Alaska Sandstone petrographic evidence and the Chugach-Prince William terrane boundary in southern Alaska
The contact between the Upper Cretaceous Valdez Group and the Paleocene and Eocene Orca Group has been inferred to be the boundary between the Chugach and the Prince William tectonostratigraphic terranes. Sandstone petrographic data from the Prince William Sound area show no compositional discontinuity across this contact. These data are best explained by considering the Valdez and Orca...

Effects of kelp forest removal on associated fish assemblages in central California Effects of kelp forest removal on associated fish assemblages in central California
Visual surveys along subtidal belt transects were used to compare fish assemblages on an experimental and a control site before and after the removal of a canopy-forming kelp forest. The giant kelp Macrocystis pyrifera (L.) C.A. Agardh was removed at the holdfast from ≈ 1 ha of high relief structurally complex rock substratum. The abundance of seven species of fish, of which five were...

Element concentrations in soils and other surficial materials of Alaska Element concentrations in soils and other surficial materials of Alaska
Mean concentrations of 35 elements, ash yields, and pH have been estimated for samples of sils and other unconsolidated surficial materials from 266 collection locations throughout Alaska. These background values can be applied to studies of environmental geochemistry and health, wildlife management, and soil-forming processes in cold climates and to computation of element abundances on...

Survival of aluminum and monel bands on black brant Survival of aluminum and monel bands on black brant
Three recoveries of Black Brant (Branta bernicla nigricans) were recently reported in the "Significant Encounters" section of North American Bird Bander (Anon. 1986). At the time of recovery these Brant were 21.5, 22 and at least 22.5 years old. The significance of these recoveries caught my attention as all were of birds banded on the Yukon Delta, Alaska in 1963 by the Alaska Department...

Stromatolite- and coated-grain-bearing carbonate rocks of the western Brooks Range: A section in Geologic studies in Alaska by the U.S. Geological Survey during 1987 Stromatolite- and coated-grain-bearing carbonate rocks of the western Brooks Range: A section in Geologic studies in Alaska by the U.S. Geological Survey during 1987
Carbonate rocks characterized by locally abundant stromatolites and coated grains have been found at several localities in the Baird Mountains and Ambler River quadrangles (fig. 1). These rocks are part of a belt of metasedimentary and metaigneous rocks that constitutes the southwestern flank of the Brooks Range; all are included in the parautochthon (Schwatka sequence) of Mayfield and...
