Glossary
rapid: Water movement along a stream channel is fast and turbulent; surface
with intermittent “white water” with breaking waves; continuous
rushing sound.
reachwide sample: All kick net samples collected at the 11 transects combined into a single composite sample.
riffle: Water moving along a stream channel, with small ripples, waves, and
eddies; waves not breaking, and surface tension is not broken; “babbling” or “gurgling” sound.
scenario: One possible deposition sequence following implementation of a
control or mitigation strategy and the subsequent effects associated
with this deposition sequence.
sensitivity: For this report, the degree to which a system is affected,
either adversely or beneficially, by an effect of nitrogen oxide or
sulfur oxide pollution (e.g., acidification, N-nutrient enrichment,
etc.). The effect may be direct (e.g., a change in growth in response
to a change in the mean, range, or variability of N deposition) or
indirect (e.g., changes in growth caused by the direct effect of N
consequently altering competitive dynamics between species and
decreased biodiversity).
signal-to-noise ratio: The ratio of the variance in the signal that you
wish to detect (site-to-site differences or temporal changes) to the
variance in the noise (variability from laboratory measurements,
field crew differences, or temporal changes within the sampling
window).
species richness: The number of species occurring in a given ecosystem, generally estimated by the number of species caught and identified using
a standard sampling regime.
specific conductance: The conductivity between two plates with an area of
1 cm 2 across a distance of 1 cm at 25°C. Provides an index of the ionic
strength of a water sample.
steady state: The condition that occurs when the sources and sinks of a
property (e.g., mass, volume, concentration) of a system are in balance (e.g., inputs equal outputs; production equals consumption).
stream flow: Water flow within a river channel, for example, expressed in
cubic meters per second (m 3 /s) or cubic feet per second (cfs). A synonym for river discharge.
subpopulation: Any defined subset of the target population.
support reach: The length of stream to be sampled at a sampling location.
synoptic survey: A survey to represent water quality across a group of lakes
or streams within a particular region.
total monomeric aluminum: Operationally defined simple unpolymerized
form of aluminum present in inorganic or organic complexes.
