Station Locations:

Station locations were determined by integrating three existing and recommended station networks: existing Ecology sites, sites recommended in 1988by the Puget Sound Water Quality Authority – Monitoring Management Committee (MMC, 1988), and from historical stations surveyed by Collias, et al. during the 1950s and 1960s. Station locations from historical lists were incorporated to promote long-term trend analyses. Where possible, recommendations for sites from the program’s clients are incorporated into the sampling strategy to report on localized conditions for these users.

Our sampling strategy incorporates 3 types of stations:

  • Core Stations (C)

Core stations are located in the center of distinct hydrographic regions, separated mainly by major sills, including deep, open basins, passages and select urban and rural embayments. These stations provide a long-term record of ambient water column conditions, annual variability and changing marine water quality conditions, as well as relationships with spatial and temporal patterns in other Puget Sound monitoring components. Currently, Ecology has active and inactive stations at 166 locations. Thirty five stations are designated for core monitoring.

  • Rotational Stations (R)
Rotational stations in Puget Sound are sampled to augment information collected from core station monitoring. These additional stations allow more extensive observation of specific regions and increase geographic coverage of the station network. These stations are located offshore, and generally in semi-enclosed embayments. Two to five rotational stations are visited every year on a rotating schedule which cycles between North, Central and South Puget Sound. Due to current funding shortages, most rotational stations are not visited and have interrupted, inconsistent data records.
Seasonal 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 just one sampling event or may be revisited when necessary in order to meet short-term and very limited objectives. The number of seasonal stations monitored each year may vary, depending on the need and the resources available.
