Term	Definition
Collections:	There are five Collection Categories - Field, Toxicity, Tissue, Taxonomy and Chemistry.  Each Collection Category summarizes counts of one or more data types (e.g. chemistry, habitat, toxicity, etc.) sampled during the Site Visit.  Sample costs vary substantially depending on the data type; for example a field pH measurement costs around $3, while a sediment toxicity identification evaluation costs around $6,300. Field QA including field duplicates and/or blanks are NOT counted.
Field Collections:	This measure represents the sum of the following data type counts: Field Measures, Habitat, and Continuous Monitoring.
Toxicity Collections:	This measure represents the sum of the following data type counts: Water Toxicity and Sediment Toxicity.
Tissue Collections:	This measure represents the sum of the Tissue data type count.
Taxonomy Collections:	This measure represents the sum of the following data type counts: Algae and Benthics.
Chemistry Collections:	This measure represents the sum of the following data type counts: Water Chemistry and Sediment Chemistry.

Data Type	Definition
Algae:	1 count represents algae collections at a single site on a given day
Benthics:	1 count represents benthic macroinvertebrate (BMI) collections at a single site on a given day
Field Measures:	1 count represents all field measures taken at a single site on a given day regardless of number of parameters to be measured
Habitat:	1 count represents any physical habitat observations for BA collections or routine field observations for WQ or Tissue collections at a single site on a given day. Each transect is counted towards the total.
Water Chemistry:	1 count represents all water chemistry collected at a single site on a given day regardless of number of parameters to be measured
Water Toxicity:	1 count represents all water toxicity samples collected at a single site on a given day regardless of the number of tests to be performed
Sediment Chemistry:	1 count represents all sediment chemistry collected at a single site on a given day regardless of number of parameters to be measured
Sediment Toxicity:	1 count represents all sediment toxicity samples collected at a single site on a given day regardless of the number of tests to be performed
Continuous Monitoring:	1 count represents a deployment at a single site spanning a discrete period of time
Tissue:	1 count represents a composite sample, made up of either individuals or multiple fish, at a single site regardless of number of parameters to be measured. At a single site, each species collected gets counted.
