IAN Seminar Series 2013
The goal of the IAN seminar series is to provide concise, thought-provoking ideas relating to Chesapeake Bay science and management. Short presentations (15 minutes maximum length) are immediately followed by a lunchtime discussion of the topics raised by the presenter. The discussion is summarized and is posted along with a pdf version of the seminar slides. The seminars are captured on video and posted under a Creative Commons license so they can be freely shared.

| Thu 29 Jul 2010 | Walter Boynton  CBL, UMCES boynton@umces.edu | Where has all the nitrogen gone? Hot spots in the land and seascape
 | Science for Citizens |
Abstract We have done a great job at figuring out where all the nitrogen comes from, but we are a little weak on where it goes. Is it going away or will it result in longer term problems? There has been a 7-Fold increase in N since John Smith's arrival to Bay Area. 50% increase during first 360 yrs and 50% increase in last 40 yrs. There are quite a few hotspots in the land and sea-scape for nitrogen sources, but also areas that remove nitrogen. A mass balance for the Patuxent tidal marshes (which represent only 2% of the basin landscape) showed 48% removal of all the nitrogen coming into the system. Rates of removal are equivalent to all the sewage treatment plants on the Patuxent. Population in the basin is going up, but the area of impervious surfaces has increased even more. Historically the Chesapeake region had significantly greater wetlands area, promoted in part by beaver activity. This has resulted in significant reductions in the rates of denitrification. The bay has nutrient obesity - too much of a good thing. Restoration goals should include fostering wetland areas. | |||
