The intent of this study is to assess various methods by which mercury in coastal salt marshes can be reduced and evaded from the water column. This project focuses specifically on general photochemical influences, autotrophic and heterotrophic bacterial contributions, and the influence of rainfall events. Rain events are especially important because they tend to deposit Hg(II) and a variety of other compounds from the air. In addition, this study will look at the effects of increased iron loading in the marine setting (as proposed in some ideas for atmospheric CO2 removal), and an increase in nitrogenous compounds (often a result of fertilizer and sewage runoff). This study will be performed in a natural estuarine enviromnent, in an attempt to account for enviromnental factors that are excluded in a laboratory setting.
