MWCI Report

Is the ranking scheme part of the MWC-Index. No , it helps place the MWC-Index into the context of pre-existing water quality patterns. What are pre-existing conditions? From 1999-2008 we established a baseline against which we can sensitively track change

Are change and water quality the same? The MWC-Index looks at change as a tool to measure progress against pre-existing conditions. It can tell us whether a change affects marine water quality positively or negatively. The focus of the index is to also account for natural oceanic influences. And climatic variability. The MWC-Index is a complementary tool for reporting water quality using national water quality standards. Maps to convey is a change in the MWC-Index occurs in a region of general water quality concern. Red and oranges show regions of lower water quality.

Why is the MWC-Index not using marine water quality standards? Standards are sparse and fail at estuarine complexity Where can I find information on marine water quality standards? http://www.ecy.wa.gov/pro grams/wq/wqhome.html

What can change tell us • Estuaries have naturally large differences in marine water conditions and water quality. This makes it challenging to apply one water quality criteria to to such a diverse system as Puget Sound and coastal bays. Instead the MWCIndex tracks how conditions at each station have changed. The conditions between 1999-2008 are not pristine, but provide an informed baseline to measure change, because we have very good data coverage, consistent methods and information on larger oceanographic and climatic patterns. • As a result the index can very sensitively detect change for each station and the struggle with the large temporal and spatial variation within Washington’s marine water bodies is omited. • To see if a change continues (trend) or finds a new equilibrium we use a statistical filter.

Significant Change • Natural conditions fluctuate from year to year, responding to climatic and oceanographic influences. • To have confidence in describing a continuing change (trend) we test if yearly index scores follow a significantly trend over a 10 year window. To do so we use the non-parametric test statistics of the Spearman Rank Correlations (N=10, p=0.05). • When a significant change in marine conditions occurs we issue maps to focus your attention towards these region. We summarize significant rends for the Marine Water Condition Index (MWCI) and the Eutrophication sub-index on maps (click here). • You can read more about the structure of the modular index here.

In this section you will see heat maps that show the monthly variability around a representative 10- year seasonal cycle for each station over a ten year time frame. We subtracted a median 10 year seasonal cycle (site specific baseline) from the data removing the seasonal cycle. This deseasonalized data set highlight the variability and trends around the baseline in color.

Station Location Station locations were determined by incorporating the existing station network used by Ecology, the rationale, and criteria set forth by the MMC in their final report (MMC, 1988), and from recommendations by the program's clients. Where possible, station locations from the historical station list were incorporated to facilitate determining long-term trends.

Core Stations Core stations are located in the center of deep basins and in urban/industrialized as well as rural embayments. These stations provide a long-term record of offshore ambient water column conditions. Currently, Ecology has active and inactive stations at 173 locations. Twenty seven stations are designated for core monitoring .

Rotating Stations Rotating stations in Puget Sound are located in distinct hydrographic regions, separated mainly by major sills. Three sets of rotating stations will be visited on a three-year rotation cycle in Puget Sound. Due to current low funding most rotational stations are not visited.

Floating Stations Floating stations are selected occasionally based on recommendations and data needs, and may be moved to fill or improve data records for other sections of the monitoring program. These locations may be visited for one sampling period or may be revisited when necessary. The number of floating stations monitored each year may vary, depending on the need and the resources available.
