The “AnchorageWaterMetals.csv” file provides metals concentrations in sediment for the Anchorage 2009 study. These are metals data analyzed by ICP/MS and are unfiltered water samples, and are comparable to the samples labeled as sample type, “total” from the Kenai data set, based on the methods used. Further information regarding quality control, and analytical lab methodology can be found in the file: “AnchorageRawSedWaterResultsMethodsQC.pdf”, included with this data submission. Column information follows: SampleID---This provides a join field to information about sample location contained in the “AnchorageSampleLog.csv” file. The columns include the Analyte, whether it was the Result or the limit of detection (LOD) and the sample units. In this datasheet, all results are milligrams per liter (mg/L, or ppm). Analyte abbreviations follow: Abbreviation FullName Ag Silver Al Aluminum As Arsenic B Boron Ba Barium Be Beryllium Br Bromide Ca Calcium Cd Cadmium Cl Chloride Co Cobalt Cr Chromium Cu Copper Fe Iron K Potassium Mg Magnesium Mn Manganese Mo Molybdenum Na Sodium Ni Nickel Pb Lead Sb Antimony Se Selenium Si Silicon Sr Strontium Th Thorium Tl Thallium U Uranium V Vanadium Zn Zinc
