Sample Design and Methods - Long-Term and Historical Marine Sediment Monitoring
Environmental Management Application
Continued annual monitoring of sediments at 10 historical PSAMP stations provides environmental managers with a valuable long-term record of changes in sediment quality over time. Managers can use this information to identify temporal trends in sediment quality that:
Long-Term and Historical Sampling Design
Since 1989, the Marine Sediment Monitoring Component has collected sediment samples from 10 long-term stations located throughout Puget Sound, Hood Canal, and the Strait of Georgia. Sediments are analyzed to determine chemical concentrations at 5-year intervals and the composition of sediment-dwelling invertebrate (benthos) communities annually (sampling schedule) (parameter list).
Each station was chosen from the list of 73 Historical Monitoring Program stations because it exhibited one or more of the following properties:
This long-term monitoring program provides a record of past and current conditions in Puget Sound sediments, and is the only long-term program providing both standardized chemistry and benthic invertebrate data throughout the Sound.
