Nitrogen loading rates for twenty-one seagrass inhabited bays in Nova Scotia, Canada / by E.J. Nagel, G. Murphy, M.C. Wong and H.K. Lotze.: Fs97-6/3260E-PDF
"Nutrient loading from anthropogenic sources has implications for the health and functioning of aquatic species and ecosystems. Using a nutrient loading model (NLM), nitrogen loading from point and non-point sources was estimated for 21 Nova Scotia bays where eelgrass (Zostera marina) has been documented. Overall, atmospheric deposition contributed most (73-100%) of the total nitrogen loading, followed by fertilizer use and discharges from seafood processing and finfish aquaculture. The highest total loading was in St. Margaret's Bay, and the lowest in Kejimkujik National Park Seaside. The maximum loading rates standardized by watershed area (yield) found in Nova Scotia were lower compared to the maximum estimates previously found in New Brunswick, and nitrogen residencies (delta-N) were much lower than in Prince Edward Island. Loading rates per estuary area were positively related to nitrogen tissue content in eelgrass leaves. This NLM can be easily updated and applied to other watersheds to compare nutrient loading rates across similar systems"--Abstract, page iv.
