Abstract:
The primary objective of this project was to determine the effects of atmospheric nitrogen deposition on the population dynamics of two distinct algal assemblages in Sarasota Bay, Florida: a nearshore, nutrient enriched community, and an offshore, nutrient poor community during both the dry (winter) and wet (summer) seasons. Short-term bioassays were designed to measure phytoplankton responses to additions of atmospherically-derived nitrogen as well as reagent-grade nitrate nitrogen. The overall project plan integrated the following elements: direct collection and measurement of atmospheric inorganic nitrogen deposition from individual storm events, in situ bioassay experiments using resident phytoplankton from a nutrient enriched estuarine community and a nutrient poor offshore community and measurement of algal growth rate and changes in algal species composition over a 3 day period as a response to nitrogen enrichment.
