Environmental Geochemical Studies of Selected Mineral Deposits in Wrangell-St. Elias National Park and Preserve, Alaska (open access)

Environmental Geochemical Studies of Selected Mineral Deposits in Wrangell-St. Elias National Park and Preserve, Alaska

From abstract: Environmental geochemical investigations took place in Wrangell-St. Elias National Park and Preserve (WRST), Alaska, between 1994 and 1997. Areas studied include the historic Kennecott stratabound copper mines and mill area; the historic mines and mill in the Bremner district, where gold was produced from polymetallic veins; the sporadically active gold placer mines at Gold Hill; the undisturbed, unmined porphyry copper-molybdenum deposits at Orange Hill and Bond Creek; and the historic mines and mill at Nabesna, where gold-bearing iron skarn deposits were exploited. The cooperative study between the U.S. Geological Survey and the National Park Service focused on identifying and characterizing geochemical signatures associated with these mineralized areas. Sample media included surface water, bedload sediment, rock, mine waste, and mill tailings samples.

Comprehensive Evaluation of Shallow Reef Fish Populations at French Frigate Shoals and Midway Atoll, Northwestern Hawaiian Islands (1992/93,1995-2000) (open access)

Comprehensive Evaluation of Shallow Reef Fish Populations at French Frigate Shoals and Midway Atoll, Northwestern Hawaiian Islands (1992/93,1995-2000)

From abstract: This document represents the sixth and last of a series of Honolulu Laboratory reports providing estimates of shallow reef fish population densities based on diver-surveys conducted at roughly annual intervals at two sites (French Frigate Shoals (FFS) and Midway Atoll (Midway) in the Northwestern Hawaiian Islands (NWHI)). The purpose of the time series has been to develop the capability to characterize the standing stock densities of shallow reef fishes, as one potentially important component of the monk seal forage base with precision sufficient to detect twofold changes over a decadal time scale when sampled at a yearly frequency.
