Transition of a regressive to a transgressive barrier island due to back-barrier erosion, increased storminess, and low sediment supply: Bogue Banks, North Carolina, USA

Preservation of a drowned gravel barrier complex: A landscape evolution study from the north-eastern English Channel

“…Many examples of landscapes that were submerged and preserved by post-glacial sea-level rise have been identified due to advances in geophysical survey techniques and increasing availability of commerciallyacquired data (Browne, 1994;Fitch et al, 2005;Storms et al, 2008;Shaw et al, 2009;Kelley et al, 2010;Timmons et al, 2010). These drowned landscapes and their component landforms are important sedimentological and geomorphological archives that are the basinward equivalent of deposits preserved on land.…”

An Automated Model to Classify Barrier Island Geomorphology Using Lidar Data and Change Analysis (1998–2014)

“…There are two primary reasons why the north is different from the south: geologic setting [6,[40][41][42][43][44] and beach nourishment [45]. Developed islands had less overall change in geomorphology because development prevents natural processes such as washover and rollover (island migration landward).…”

Insight into the late Holocene sea-level changes in the NW Atlantic from a paraglacial beach-ridge plain south of Newfoundland

“…It can provide a very detailed and continuous view of the subsurface by imaging the internal structures and relative positioning of sedimentary deposits (e.g., van Heteren et al, 1998;Neal et al, 2003;Engels and Roberts, 2005;Timmons et al, 2010;Weill et al, 2012). GPR data were acquired using a GSSI SIR- …”

“…Moreover, the rate of RSL rise at Saint-Pierre-etMiquelon over the period of barrier formation is similar to rates reported during the period for development of similar systems (barriers or beach ridge plains) in the northwest Atlantic. For example, formerly transgressive barriers stabilized and began prograding in the western Gulf of Maine (Plum Island, Massachusetts) and along the Outer Banks barrier island chain (Bogue Banks, North Carolina) as RSL rise rates slowed to < 1.5 mm/yr and 0.8 mm/yr, respectively (Timmons et al, 2010;Hein et al, 2014a). Likewise, these rates were < 1.4 mm/yr on the south coast of New Brunswick (Bay of Fundy) (Gehrels et al, 1996; and < to 2 -2.4 mm/yr at Halifax (Nova Scotia) over the last 3000 years (Scott et al, 1995).…”

“…Regressive barriers and beach-ridge systems, prograding coastal features formed when sediment accumulation rates exceed creation of accommodation (vertical space available for sediment) by RSL changes (Galloway and Hobday, 1983;Davis and FitzGerald, 2004;Bristow and Pucillo, 2006;Timmons et al, 2010), have the potential to record past coastal responses to environmental change (Stapor, 1975;Otvos, 2000;Guedes et al, 2011;Tamura, 2012). For example, regressive coastal systems have been used to provide insight into Holocene RSL changes (e.g., van Heteren et al, 2000;Rodriguez and Meyer, 2006;Clemmensen et al, 2012;Hede et al, 2013;, changes in sediment supply (e.g., FitzGerald et al, 1992;Brooke et al, 2008;Sanjaume and Tolgensbakk, 2009), climatic changes (e.g., Goy et al, 2003;Allard et al, 2008;Nott et al, 2009) and variations in wave regimes (e.g., Dominguez et al, 1987;Goodwin et al, 2006;Rodriguez and Meyer, 2006).…”
