COLLECTION GRAB-MISC Grab sampler, type unspecified Y
COLLECTION FISH-TRAP Fish, crab, lobster (etc.) collection, trap or pot Y
MEASUREMENT BIOHabitatMetric031 Percent of sample composed of Oligochaeta and Hirudinea (worms and leaches) Y
MEASUREMENT BIOHabitatMetric004 The percent of the sample represented by organisms that feed on fine organic matter while buried in the sediments. Y
MEASUREMENT BIOHabitatMetric051 Total number of taxa present in the sample Y
MEASUREMENT BIOHabitatMetric045 Compares diversity by accounting for both richness and evenness of the sample. Generally this metric scores between 0 and 4.5. A higher score represents higher diversity. It is not used to compare sites, however since it is affected by changes in both the number of taxa and the relative abundance of those taxa. Y
COLLECTION CORE-VIB4 Corer, Vibra-, 4 in diameter by 12 ft length Y
MEASUREMENT BIOHabitatMetric011 A community tolerance quotient based on the tolerance of taxa in the sample to alkalinity and sulphates, and the selectivity of taxa in the sample for or against fine substrates and low stream gradients (Winget and Mangum, 1979). This weighted abundance measure ranges from 2 (unpolluted) to 108 (severely polluted). Y
MEASUREMENT BIOHabitatMetric021 The number of taxa in the sample representing organsims that consume fine particulate organic matter from the water column Y
MEASUREMENT BIOHabitatMetric023 Number of taxa in the sample that uses Hemoglobin to carry oxygen in their bodies. These are usually an indicator of low oxygen conditions. Y
ANALYSIS NWVPH Determination of Volatile Petroleum Hydrocarbons (VPH) Fractions Washington Department of Ecology, 1997. Analytical Methods for Petroleum Hydrocarbons. Ecology Publication No. 97-602. Y
COLLECTION CORE-GRVTY Corer, piston or gravity Y
MEASUREMENT BIOHabitatMetric022 Percent of the taxa in the sample that uses Hemoglobin to carry oxygen in their bodies. These are usually an indicator of low oxygen conditions. Y
MEASUREMENT BIOHabitatMetric050 The number of taxa in the sample represented by organisms that can control the speed and direction of movement in the water column. Y
MEASUREMENT BIOHabitatMetric029 Percent of the taxa in the sample that produces more than 2 generations per year Y
COLLECTION CORE-BX.1 Corer, box, 0.1 m2 Y
MEASUREMENT BIOHabitatMetric018 Number of taxa representing Ephemeroptera, Plecoptera, and Trichoptera within the sample Y
COLLECTION GOFLOW-TEF Bottle, GoFlow, Teflon lined Y
ANALYSIS CRSO-FJ Chromium Reducible Sulfide (CRS) by Fossing and Jorgenson, 1989. Fossing, H. and Jorgensen, B.B. (1989) Measurement of bacterial sulfate reduction in sediments: Evaluation of a single-step chromium reduction method. Biogeochemistry 8, 205-222. Y
ANALYSIS TURB-LNRM Turbidity, nephelometric, lab non-ratio meter (white light, 90 deg detector only) Y
ANALYSIS PHOS-OLSEN Soil Phosphorus, Olsen Method, NaHCO3 Extraction, Colorimetric, Ammonium Molybdate/Ascorbic Acid Olsen, S. R. and L. E. Sommers. 1982. Phosphorus. p. 403-430. In: A. L. Page, et al. (ed.) Methods of soil analysis: Part 2. Chemical and microbiological properties. American Society of Agronomy, Monograph No. 9. Y
COLLECTION AUGER-STM Auger, steam Y
MEASUREMENT BIOHabitatMetric010 The percent of the sample made up of organisms that consume fine particulate organic matter, and include both Gatherers (those who collect from the bottom substrate) and Filterers (those who collect from the water column) Y
COLLECTION VANVEEN.60 Grab sampler, Van Veen, 0.60 m2 Y
MEASUREMENT BIOHabitatMetric047 Measures diversity by reporting the chance that any two randomly drawn individuals from a sample are the same species. This measure is heavily influenced by relative abundance of each taxa. The measure scores between 0 and 1, with a more diverse community reflected by a score close to 1. Y
COLLECTION CORE-SHLBY Corer, Shelby tube Y
ANALYSIS Holme1971 Grain Size Distribution by Sieve-Pipette, Holme and McIntyre, 1971 Holme, N.A. and A. D. McIntyre, 1971, Methods for the study of marine benthos, IBP hand-book no. 16. Blackwell Scientific Publications, Oxford, 334 p. Y
MEASUREMENT BIOHabitatMetric008 Percent of the taxa in the sample that survive in a narrow range of cold water temperatures Y
MEASUREMENT BIOHabitatMetric037 The ratio of organsims that feed on attached periphyton (Scrapers) to the number of organisms that feed by filtering organic matter from the water column (Filterers). Y
MEASUREMENT BIOHabitatMetric003 Ratio of Baetidae/Ephemeroptera within the sample Y
MEASUREMENT BIOHabitatMetric053 Number of taxa in the sample that produces a single generation per year Y
ANALYSIS Solarzan69 Ammonia-Nitrogen in water by phenol-hypochlorite method. Salarzano, L., 1969. The determination of ammonia in natural water by the phenol-hypochlorite method. Limnol. Oceanogr. 14(5):799-801. Y
MEASUREMENT BIOHabitatMetric020 The percent of the sample made up of organisms that consume fine particulate organic matter collected from the water column Y
MEASUREMENT TURB-FRM Turbidity, nephelometric, field ratio meter (white light, 90 deg detector w/correction detectors) Y
