Marine Water Quality Monitoring in Washington State
Entry ID: wa_de_marinewaterquality


Summary
Abstract: The Washington State Department of Ecology has conducted marine water
quality monitoring at a number of stations in Puget Sound, Grays
Harbor and Willapa Bay since 1973. About 40 stations are monitored
each year on a monthly basis. Some stations are monitored every year
while some are monitored on a rotating schedule.

Parameters monitored include profiles of temperature, salinity,
density, dissolved oxygen, light transmission, pH, as well as discrete
samples at various depths for fecal coliform bacteria, chlorophyll a,
phaeopigment, nitrate, nitrite, ammonium, orthophosphate, silicate and
Secchi disk depth. Generally samples were taken at 0, 10, and 30
meters depth.

The monitoring data are used to assess marine water quality. Summary
analyses show relative water quality concern and sensitivity to
eutrophication for sites within Puget Sound. The latest edition of
Washington State Marine Water Quality report can be viewed or
downloaded for more information.

Information was obtained from
"http://www.ecy.wa.gov/programs/eap/mar_wat/mwm_intr.html and from Jan Newton."

Quality
Data quality and measurement procedures have varied significantly over
the period. Beware of these attributes before any analysis of these
data. Data quality is indicated by a data qualifier code (qc) with
four levels 1-state of the art method, adequate quality control 2-Less
precise method, quality control, 3-Known or suspected data problem;
4-Unknown method or quality control, C-calculated value.
