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.

The Hawaiian Monk Seal in the Northwestern Hawaiian Islands, 1998 (open access)

The Hawaiian Monk Seal in the Northwestern Hawaiian Islands, 1998

The following report provides the findings of a 1998 field study over the Hawaiian monk seal in the Northwestern Hawaiian Islands. These studies evaluate the status and trends of monk seal populations, natural history traits (survival, reproduction, growth, behavior, and feeding habits), and the success of various activities designed to facilitate population growth.

Identification Manual for Dietary Vegetation of the Hawaiian Green Turtle Chelonia mydas (open access)

Identification Manual for Dietary Vegetation of the Hawaiian Green Turtle Chelonia mydas

From introduction: This manual is designed to assist sea turtle biologists and other non-physologists in the identification of the food items contained in the gastrointestinal tract of green turtles (Chelonia mydas) sampled from the Hawaiian Islands. The manual contains many of the most common algal species found in crop/stomach samples taken from Hawaiian green turtles.
