Mike; I have a spread sheet of the O2 levels for Patapsco, Annapolis, Gooses, and Patuxant on my other computer. When I get time, I will post some numbers. I don't know about the 30 day average, but my single day results showed the O2 numbers being bad and moving south. Maybe the outgoing tides move the "mahogany tide" southwards toward the Annapolis buoy.
On TF there is a post about a fish kill off Podickery Point on the 30th. This would support the theory it's moving south.
Later
5th (Marty)
