Most crops are intolerant of salinity and thus minimization of saltwater intrusion due to storms and high tide events is critical to crop preservation and economic stability. The objective of this study is to explore how marsh migration impacts the extent of surface and subsurface salinization due to storm surges. We also examine the short- and long-term environmental and financial benefits of marsh migration into coastal agricultural land subject to storm surge inundation.<\/p>\n<p><strong>Software: <\/strong>HydroGeoSphere<\/p>\n\n\t<div style=\"width: 640px;\" class=\"wp-video\"><!--[if lt IE 9]><script>document.createElement('video');<\/script><![endif]-->\n<video class=\"wp-video-shortcode\" id=\"video-198-1\" width=\"640\" height=\"360\" preload=\"metadata\" controls=\"controls\"><source type=\"video\/mp4\" src=\"https:\/\/www2.whoi.edu\/staff\/jguimond\/wp-content\/uploads\/sites\/300\/2023\/02\/previous_2_SJR_modelvido.mp4?_=1\" \/><a href=\"https:\/\/www2.whoi.edu\/staff\/jguimond\/wp-content\/uploads\/sites\/300\/2023\/02\/previous_2_SJR_modelvido.mp4\">https:\/\/www2.whoi.edu\/staff\/jguimond\/wp-content\/uploads\/sites\/300\/2023\/02\/previous_2_SJR_modelvido.mp4<\/a><\/video><\/div>\n<h3>Impacts of sea-level rise on coastal wetland hydrology and carbon dynamics<\/h3>\n<p>As sea-level rise threatens to drown coastal wetlands, the longevity of coastal wetland ecosystem services is unknown, particularly coastal wetland carbon sequestration.

Specifically, the mechanisms, magnitudes, and timing by which crab burrows influence wetland carbon fluxes are still to be determined. The objectives of this project were to 1) quantify the effects of crab burrows on salt marsh hydrology and geochemistry via changes in sediment permeability and redox potential and 2) identify how and how much crab activity causes carbon loss, or reduced carbon sequestration, in salt marshes.<\/p>\n<p><strong>Project location:<\/strong> <a href=\"https:\/\/dnrec.alpha.delaware.gov\/coastal-programs\/research-reserve\/\" target=\"_blank\" rel=\"noreferrer noopener\">St. Jones National Estuarine Research Reserve<\/a>, Dover, Delaware<\/p>\n\n\n","protected":false},"excerpt":{"rendered":"<p>Previous Projects Impacts of marsh migration on saltwater intrusion into coastal agricultural fields Coastal agricultural fields are vulnerable to storm surge inundation and salinization.
