Eadie" Organization: NOAA-GLERL X-Accept-Language: en To: eegle-pi@wings.glerl.noaa.gov Subject: Help I would like to ask all of the EEGLE PIs to provide me with a paragraph encapsulating the major findings of their EEGLE research and how this information can be used - its social relevance. Please respond by August 15. I need this for at least two reasons, the introductory paper for the JGR synthesis volume and to respond to several inquiries from both Congressional staffs and interested supporters of Great Lakes research. For example, we gave several interviews about the program and its goals in 1998 and 1999. Some of the same reporters are now wanting to know what we have learned for a follow-up story. Attached below is a draft of my trap paragraph as an example. Draft 7/26/02 Brian J. Eadie Summary EEGLE paragraph Sediment trap experiments confirmed the impression that storms are very significant in both sediment-water exchange of nutrients and contaminants and in moving sediments into depositional zones. Measurements showed that, as a consequence of storms, approximately 80% of sediments and associated constituents are delivered into depositional regions in less than 20% of the year. These sediment resuspension events also internally recycle several times the annual external input of phosphorus along with very large amounts of PCBs and other constituents. Such storm events are unlikely to be sampled in monitoring programs and need to be included in any lake management scheme or regulatory considerations. Mass balance modeling approaches need to be calibrated to include impacts of these episodic events.
