EPA oyster project: nitrogen in water. - Transport and fate of nutrient and pathogen loadings into nearshore Puget Sound: consequences for shellfish growing areas

This project seeks to develop and apply an assessment of shellfish growing area (SGA) vulnerability to closures caused by watershed- and marine-derived pathogens. Using empirical data and quantitative models, we will examine the impacts of alternative watershed management strategies, nearshore protection, and climate on the vulnerability of three SGA.

Outputs include the following:

1) Maps of the spatial distribution of terrestrial and marine-derived sources of nutrients and pathogens.

2) Validated model estimates of transport of nutrients and pathogens to SGA under future climate and restoration strategies.

3) Assessments of the fate of nutrients and pathogens in terms of changes in ecosystem service values provided by SGA--filtration, food web support, and socio-economic impacts due to harvest closures. Outcomes include improvements in the ability of shellfish growers and managers to classify vulnerability of SGA according to risk of future closures, and to prioritize strategies for improving delivery of shellfish-related ecosystem services and values.

At this time, contact the Data Manager for information on obtaining access to this data set. In the near future, the NWFSC will strive to provide all non-sensitive data resources as a web service in order to meet the NOAA Data Access Policy Directive (https://nosc.noaa.gov/EDMC/PD.DA.php).

Access Database

Medium

These data were collected and processed in accordance with established protocols and best practices under the direction of the project’s Principal Investigator. Contact the dataset Data Manager in section 3 for full QA/QC methodology.

No Delay

The Northwest Fisheries Science Center facilitates backup and recovery of all data and IT components which are managed by IT Operations through the capture of static (point-in-time) backup data to physical media. Once data is captured to physical media (every 1-3 days), a duplicate is made and routinely (weekly) transported to an offsite archive facility where it is maintained throughout the data's applicable life-cycle.
