The Effect of Hurricane Irma Storm Surge on the Freshwater Lens in Big Pine Key, Florida using Electrical Resistivity Tomography

Abstract: Animals and plants on low elevation oceanic islands often rely on a thin lens of fresh groundwater and this lens is vulnerable to seawater contamination from storm surge. Documentation of the impact of the storm surge on the freshwater lens and its subsequent recovery is limited. In September 2017, Hurricane Irma made landfall in the Florida Keys as a category 4 storm with storm surge heights in excess of 2 m. This study used Electrical Resistivity Tomography (ERT) to investigate the effect of the storm surge … Show more

“…The smallest value of 0.01 was reached in a sandy beach in Chincoteague Bay (DE) (Figure 1, Table S1 in Supporting Information S1), due to the weaker ability of the soil to retain water. (Anderson, 2002;Cardenas et al, 2015;Hedgespeth et al, 2021;Keim et al, 2007;Kiflai et al, 2020;McDowell et al, 1996;Sawyer et al, 2014;Terry & Falkland, 2010;Van Biersel et al, 2007;Vithanage et al, 2012;Wachnicka et al, 2020;Williams, 1993).…”

“…The ERT image indicated low resistivity/high salinity zones in the upper 2 m depth corresponding to saline water emplaced on the top of the freshwater lens by the storm surge (Figure 2c,d). This deposition of saline water on top of the freshwater lens defined by the 3 practical salinity unit (PSU) contour lines is observed in the lower elevation sections of the profiles (Kiflai et al., 2019). This low resistivity/high salinity is clearly visible east of 130 m on the profile.…”

“…A coincident ERT survey of 220 m long was conducted along the EM transect on the western shoreline of the island in January, May and December 2018 at the same location (Figures 1 and 2; Kiflai et al., 2019). The ERT surveys were collected with an AGI Super Sting R1/IP metre using a 2 m electrode spacing in a roll along Wenner Array configuration.…”

“…We take a geophysical approach to detect spatial and temporal variation in salinity profiles that would reflect diel signatures of water uptake by the trees and hydraulic redistribution of atmospherically-sourced fresh water from the trees into the soil. Timelapse electrical resistivity imaging (ERI) has proven useful in imaging changes in soil moisture and root uptake (e.g., Beff et al, 2013;Brillante et al, 2016;Consoli et al, 2017;Daily et al, 1992;Garré et al, 2011;Lewis et al, 2016;Mares et al, 2016;Mary et al, 2020;Musgrave and Binley, 2011), the mobility of saline tracers (e.g., Binley et al, 1996;Cassiani et al, 2006;Kemna et al, 2002;Robinson et al, 2020;Singha and Gorelick, 2005;Slater et al, 1997;Slater and Sandberg, 2000) or contaminants (e.g., Hayley et al, 2009;Mansoor and Slater, 2007), and changes in both soil moisture and salinity in saline environments (Attwa et al, 2011;Boaga et al, 2014;Brindt et al, 2019;deFranco et al, 2009;Kiflai et al, 2020;Leroux and Dahlin, 2006;Slater and Sandberg, 2000;Sutter and Ingham, 2016;Urish and Frohlich, 1990;Vacher et al, 2008). This paper reports on the observations made with a time-lapse ERI survey coupled with real-time groundwater data and tidal records.…”
