This study investigates the spatial extent of the Hurricane Ike sediment deposit on a coastal marsh at McFaddin National Wildlife Refuge in Southeast Texas. Fieldwork conducted in summer 2017 involved digging shallow trenches on a transect about 675 m west of a transect in a previous study. Preliminary results indicate that the Hurricane Ike deposit has been identified at five trench sites on the current transect, and that the deposits thin out further inland. Future research will involve work on three more transects stretching from High Island, Texas to Sabine Pass, Texas. The goal of this study is to discover spatial variations of the Hurricane Ike storm surge sediment deposit in relation to the landfall location of Hurricane Ike. The findings of this study should provide improved understanding of the spatial relationship between storm surge sedimentation and storm surge heights, valuable knowledge about the sedimentary response of coastal marshes subject to storm surge deposition, and useful guidance to public policy aimed at combating the effects of sea level rise on coastal marshes along the northern Gulf of Mexico coastline.
