<p class="MsoNormal" style="background:white"><span style="color:black"><o:p> </o:p></span></p>
<p style="background:white"><b><span style="color:black">Abstract</span></b><span style="color:black">:</span><span style="font-family:"Times New Roman",serif"><o:p></o:p></span></p>
<p style="mso-margin-top-alt:12.0pt;margin-right:0in;margin-bottom:12.0pt;margin-left:0in;background:white">
<span style="color:black">Land development can alter coastal morphology, shallow groundwater flow paths, and the composition of groundwater reaching the ocean. Subterranean estuaries (STEs) are increasingly recognized as biogeochemically reactive zones. Little
is known about carbon and nutrient transformations along anoxic groundwater flow paths through deeper (2–3 m), old or recently buried organic-rich deposits. This gap is important because the amount and reactivity of organic matter can strongly regulate the
attenuation of land-derived contaminants such as anthropogenic nitrogen and affect coastal water quality.</span><o:p></o:p></p>
<p class="MsoNormal" style="background:white"><span style="color:black">In this talk, I will present results on biogeochemical transformations in an organic-rich STE in Mobile Bay, AL, which was formed when a salt marsh was buried during residential development
in the 1970s. Field shallow geophysical exploration and sediment core collection show that these buried, organic-rich marsh deposits currently act as a conduit for shallow groundwater discharge. Nitrogen balance indicates that these deposits substantially
attenuate anthropogenic NO₃</span><span style="font-family:"Cambria Math",serif;color:black">⁻</span><span style="color:black"> transported toward the coast. However, degradation of the buried marsh organic matter releases DOC, DON, and NH₄</span><span style="font-family:"Cambria Math",serif;color:black">⁺</span><span style="color:black">
into groundwater. We hypothesize that these products may ultimately reach coastal waters, increase the oxygen demand, and potentially contribute to coastal hypoxia.<o:p></o:p></span></p>
<p class="MsoNormal" style="background:white"><span style="color:black"><o:p> </o:p></span></p>
<p class="MsoNormal" style="background:white"><span style="color:black">More recent experiments also demonstrate that these processes are sensitive to environmental conditions expected to change in shallow coastal aquifers. For example, we found that salinization
alters both DOM composition and the mechanisms responsible for NH₄</span><span style="font-family:"Cambria Math",serif;color:black">⁺</span><span style="color:black"> mobilization, while longer residence times lead to accumulation of increasingly degraded
DOM.<o:p></o:p></span></p>
