COLLECTION DIRECTPUSH Direct Push (like Geoprobe) Y
Preparation SIEVE-2.0MM Sieved with a 2.0 millimeter screen Y
Preparation FILTER1.2um-GFF Sample filtered with 1.2 micron glass fiber filter (GFF) Y
Collection HYDROLAB Collected using Hydrolab multi-parameter probe Y
Preparation SIEVE-1.0MM Sieved with 1.0 millimeter screen Y SIEVE-1MM
Measurement Fluorometer-generic Fluorometer, generic. Exact type not specified. Y
COLLECTION SHIPEK.04 Grab sampler, Shipek, 0.04 m2 Y
Collection HVPUFAir High-volume polyurethane foam (PUF) air sampler. Y
COLLECTION VANVEEN.25 Grab sampler, Van Veen, 0.25 m2 Y
COLLECTION FISH-TRAP Fish, crab, lobster (etc.) collection, trap or pot Y
Collection PDB-SedPoreWater Passive Diffusion Bag (PDB) Sediment Pore Water Sampler Y
Collection WIPE-MISC Surface wipe, material unspecified Y
Collection LVPUFAir Low-volume polyurethane foam (PUF) air sampler. Y
MEASUREMENT BIOHabitatMetric031 Percent of sample composed of Oligochaeta and Hirudinea (worms and leaches) Y
COLLECTION GRAB-MISC Grab sampler, type unspecified Y
Preparation FILTER5um Water sample filtered with 5 micron (micrometer) filter (material unspecified) Y FILTER5M
Preparation DRIED104C Sample dried at 104 degrees C Y
Collection PUMP-INERTIAL-LIFT Pump, WaTerra inertial lift or similar Y PUMP-INERTIAL
MEASUREMENT BIOHabitatMetric004 The percent of the sample represented by organisms that feed on fine organic matter while buried in the sediments. Y
COLLECTION CORE-VIB4 Corer, Vibra-, 4 in diameter by 12 ft length Y
COLLECTION STM-FieldGroup14 Large Woody Debris - This method explains how to count pieces of large woody debris in waded streams for the Status and Trends Program when traversing the length of the stream site. Observations are limited to the main channel. This method applies to streams of Western Washington (west of the Cascade ridge), where natural conditions are expected to include larger sizes of wood. Y
Measurement GWLMU Groundwater level by sonic meter Y
MEASUREMENT BIOHabitatMetric051 Total number of taxa present in the sample Y
ANALYSIS PLM-DS Asbestos by Polarized Light Microscopy and Dispersion Staining, exact method unknown 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
Preparation FILTER.45um-PP Water sample filtered with 0.45 micron (micrometer) polypropylene filter (PP) Y FILTER.45M-PP
Preservation Cool10DegC Sample kept cool at 10 degrees Celsius Y
Derivation RHumidityLoggerCalc Relative humidity by data logger, calculated from water vapor partial pressure divided by the saturated vapor pressure at the ambient temperature Y
COLLECTION PDB-GW Passive Diffusion Bag (PDB) Groundwater Sampler Y
Collection EquilPassiveGrab-GW Equilibrated Passive Grab Groundwater Sampler 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 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
MEASUREMENT BIOHabitatMetric021 The number of taxa in the sample representing organsims that consume fine particulate organic matter from the water column Y
PREPARATION DRIED550C Sample dried at 550 degrees C Y
Preparation FILTER11um-CA Water sample filtered with 11 micron (micrometer) cellulose acetate filter (CA) Y
MEASUREMENT TIDETABLE Derived from Tide Table Y
Collection MidwaterTrawl Fish collection by towing a cone-shaped net at a chosen depth in the water column. Also known as pelagic trawling. Y
COLLECTION CORE-GRVTY Corer, piston or gravity Y
Collection BottomTrawl Fish collection by dragging a net along the bottom. Also known as benthic trawling. 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
Derivation DEPTH-MLLW Depth calculated using depth sounder and Mean Lower Low Water (MLLW) tidal datum Y
Derivation CALC_IRON Ferric Iron by calculation (Total Iron – Ferrous Iron) 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
PRESERVATION FORMALIN10% Preserved with 10 percent Formalin (formaldehyde) Y FORM10%
MEASUREMENT BIOHabitatMetric029 Percent of the taxa in the sample that produces more than 2 generations per year Y
Collection AtmDepFunnelSS Stainless steel funnel and collector for wet, dry, and/or bulk atmospheric deposition. Y
Derivation NCALC-351.2-4500NO3F Total Nitrogen calculated by adding Total Kjeldahl Nitrogen by EPA351.2 (Semiautomated Colorimetry) and Nitrate-Nitrite by SM4500NO3F (Nitrogen (as Nitrate, NO3) by Automated Cadmium Reduction Method) Y
Derivation CALC-FLOW-VOLUME Total volume of flow over time Y
COLLECTION CORE-BX.1 Corer, box, 0.1 m2 Y
PREPARATION FreezeDry Freeze-dried prior to analysis Y
