Past projects National Tissue and Sediment Sample Archive: Many of NOAA's projects incorporate different programs to obtain the desired information. The National Status and Trends program of NOAA's started using mussel, oyster, and zebra mussel samples collected under the Mussel Watch Program in 1985 as a means to start specimen banking. This bank of samples allows NOAA to take a snapshot of certain contaminants of interest at any point in time allowing, through the use of analytical techniques, the tissue concentrations of the desired compound. This allows regulators to better understand the history of a certain compound. Another project that took advantage of the Mussel Watch program was the assessment of coastal waters impacted by Hurricane Katrina in 2005. By examining shallow waters for concentrations of DDT, conventional chlorinated pesticides, PCBs, PAHs, and metals after the hurricane NOAA scientists were able to compare results with the past 20 years of monitoring data from the same area. This consistent and historical record of contaminants from the Mussel Watch program proved effective in analyzing the impacts of Hurricane Katrina.
Pathology of parasites in bivalves, using oysters and mussels collected via the Mussel Watch program tissue samples were investigated for parasites. The change in abundance of parasites geographically and over time can be a good indicator of exposure to a contaminant. The results of these pathology screenings have been used to show levels of contamination and have affected regulatory decisions.
Notable publications Mussel Watch publishes reports approximately every 2 years concerning most sites and regions. Some compilations and other notable publications historically produced include: • An Assessment of Two Decades of Contaminant Monitoring in the Nation's Coastal Zone
Current projects ''Great Lakes Mussel Watch Supports the President's Great Lakes Restoration Initiative'' is one of the many ongoing projects by Mussel Watch. This project, receiving attention and funding from the President's Great Lakes Restoration Initiative (GLRI), is a typical example of the types of projects Mussel Watch is being used for. Looking at
Areas of Concern (AOC) in the US Great Lakes, Mussel Watch has increased sampling sizes and rates as well as updated techniques including doing caged mussel testing when shellfish beds are not available. By looking at both sediment and mussel tissue concentrations researches have been able to better identify remediation efforts at Great Lake AOC. Like many other current Mussel Watch projects, the GLRI is using both historical data from Mussel Watch as well as increasingly more temporally and spatially prioritized data leading to more robust data sets far more applicable to specific AOC. == Significance ==
