sample

Sample Identification Number uniquely identifies each sample; use to link sample information with all hydrocarbon analyses

Optional sample depth in meters, measured from mean lower low water (MLLW) as measured or estimated by the sample collector

Abbreviated names for Exxon Valdez Trustee Natural Resource Damage Assessment and Restoration projects

Identifies source of project funding; the most common, as of 2010, is the Exxon Valdez Oil Spill Trustee Council (EVOSTC).

Provides the project number assigned by the funding agency (required for EVOSTC projects). For further project detail, use projectCode with the EVOSTC website search engine (http://www.evostc.state.ak.us/Projects/SearchStart.cfm).

Alphanumeric identifier assigned to the sample by field personnel or the principal investigator.

Method used to collect the sample. See table Collection Methods for further detail.

Identifies sample type. Valid sample types (as of 2013) are agarose, blank, coal, creosote, oil, suspended particulate matter (PARTICLT), peat, PEMD, sediment, SPMD, tissue, rinse, and water. See table Matrices for further detail

Specific additional information about matrix [such as WHOLE (whole specimen), egg, stomach, tarball and asphalt].

Species used for tissue samples. See table species for further explanation

Date sample was collected (required).

Year sample was collected (required)

General sample collection area (required); see table LOCATION for abbreviations. Location refers to general areas, not specific latitudes and longitudes

Last name of individual responsible for the collecting, handling, and security of field samples.

Organization responsible for sample collection

Latitude in decimal degrees. Required for all environmental samples (optional for blanks and generally not needed for experimental samples).

Longitude in decimal degrees. Required for all environmental samples (optional for blanks and generally not needed for experimental samples). Note that West longitudes are negative

Identifies the type of sample: ENV = environmental, EXP = experimental, blank = blank sample for quality assurance purposes, spike = spiked blank, OTHR = other type of sample (e.g., samples collected to test municipal water supply).

Identifier of reliability of the analytical results for individual samples. Good = no problems, BIAS = probable problems with the analytical data (Short et al. 1996b)
