Title:
Chemical data for rock, sediment, biological, precipitate, and water samples from abandoned copper mines in Prince William Sound, Alaska
Abstract:
In the early 20th century, approximately 6 million metric tons of copper ore were mined from numerous deposits located along the shorelines of fjords and islands in Prince William Sound, Alaska. At the Beatson, Ellamar, and Threeman mine sites (fig. 1), rocks containing Fe, Cu, Zn, and Pb sulfide minerals are exposed to chemical weathering in abandoned mine workings and remnant waste piles that extend into the littoral zone. Field investigations in 2003 and 2005 as well as analytical data for rock, sediment, precipitate, water, and biological samples reveal that the oxidation of sulfides at these sites is resulting in the generation of acid mine drainage and the transport of metals into the marine environment

    Date: 2003 (process 1 of 2)
    Twenty rock samples were analyzed in laboratories of the U.S. Geological Survey in Denver, Colorado (table 2). Most major and trace elements were determined by inductively coupled plasma-mass spectrometry following multi-acid (HCl-HNO3-HClO4-HF) digestion (Briggs and Meier, 2002). Mercury was determined by cold-vapor atomic absorption spectroscopy (Brown et al., 2002a), Se by hydride-generation atomic absorption spectrophotometry (Hageman et al., 2002), total S and total C by combustion (Brown and Curry, 2002a,b), and CO2 and carbonate carbon by coulometric titration (Brown et al., 2002b). Additional details regarding sample preparation and detection limits are found in Taggert (2002). In addition, gold in fourteen samples was analyzed by the fire assay technique at XRAL Laboratories, Toronto, Canada. Detailed mineralogical descriptions and electron microprobe data for sulfide minerals are presented in Koski and others (2008).
    Twenty-six sediment samples from the Ellamar, Threeman, and Beatson sites were analyzed in laboratories of the U.S. Geological Survey in Denver, Colorado (table 4). Major and trace elements were determined by inductively coupled plasma-mass spectrometry following multi-acid (HCl-HNO3-HClO4-HF) digestion (Briggs and Meier, 2002) except for mercury, which was analyzed by cold-vapor atomic absorption spectroscopy (Brown et al., 2002).
    In 2005 marine organisms including mussels, barnacles, gastropods, clams, limpets, eelgrass, and algae were collected from intertidal zones at the Ellamar, Threeman, and Beatson sites (table 5). Biological samples were frozen shortly after collection, and were analyzed in laboratories of the U.S. Geological Survey in Denver, Colorado (table 6). Tissue from animal specimens was hand picked from shell material using tweezers and then freeze dried prior to grinding and analysis. Major and trace elements were determined by inductively coupled plasma-mass spectrometry following multi-acid (HCl-HNO3-HClO4-HF) digestion (Briggs and Meier, 2002) except for mercury, which was analyzed by cold-vapor atomic absorption spectroscopy (Brown et al., 2002).
