N or P? | Gordon Goldsborough on Lake Winnipeg Dispatches
-
- News
Dr. Gordon Goldsborough studies coastal wetlands, which includes the swampy areas along the southern shores of lakes Manitoba and Winnipeg. In this comprehensive interview he brings us closest to the actual lake, especially in to the troubled waters of Netley-Libau Marsh, the damaged ‘kidneys’ where the Red River finishes its journey.
Goldsborough, an associate professor in the Department of Biological Sciences at the University of Manitoba, helps us understand what’s happening in those shallow waters and what it means farther north in the lake itself. He offers insight into his research and ideas as to what can be done to reduce the pressures on the lake.
And in a departure from the view among most Lake Winnipeg scientists, he doesn’t agree with the orthodoxy that phosphorus is the primary cause of high algae growth. Goldsborough says that nitrogen is equally important. He cites his research in shallow water rather than in much deeper lakes, typical of the Experimental Lakes Area (the ground zero of many scientists active in issues of lake health) and shows that both N and P are culprits in what’s going on.
This is another full interview I am posting as this co-creation continues. Why am I publishing this? I figure that if you listen to what Goldsborough has to say it will help identify key insights needed to build this story about Lake Winnipeg. Let me know what stands out for you.
Don’t miss the earlier interviews with Vicki Burns, Bill Barlow, Les McEwan, Hank Venema and David Lobb.
