“…Taken together, these features indicate a rapid deposition of allochthonous clastic material under high-energy conditions. As the isotopic changes (heavier δ 13 C and δ 15 N, decreased TOC/TN ratio, lower TOC and TN) are exactly the changes documented as occurring during marine intrusions along the northern Gulf Coast (Lambert et al, 2008;Das et al, 2013), and the complete burial of plant cover resembles documented effects of hurricanes (Guntenspergen et al, 1995), the most likely source of this anomalous material is transport by a large storm surge associated with a tropical cyclone. As the 137 Cs chronology indicates that 1963 correlates approximately a depth of 37.5 cm, the causative storm must have occurred sometime after that year.…”

The Effects of Tropical Cyclone-Generated Deposition on the Sustainability of the Pearl River Marsh, Louisiana: The Importance of the Geologic Framework

Shoreline retreat is a tremendously important issue along the coast of the northern Gulf of Mexico, especially in Louisiana. Although this marine transgression results from a variety of causes, the crucial factor is the difference between marsh surface elevation and rising sea levels. In most cases, the primary cause of a marsh's inability to keep up with sea level is the lack of input of inorganic material. Although tropical cyclones provide an important source of such sediment, little effort has been made to determine the point of origin of the deposited material. In this study we use sedimentary, geochemical and biogeochemical data to identify the bed of the Pearl River and/or Lake Borgne as the source of a ∼5 cm thick clastic layer deposited on the surface of the Pearl River marsh on the Louisiana/Mississippi border. Radiochemical chronologies and sedimentary evidence indicate that this layer was associated with the passage of Hurricane Katrina in 2005. As this material would otherwise have been lost to the system, this deposition indicates a net gain to marsh surface elevation. Accretion rates, determined from 137Cs and 14C profiles and the use of the Katrina layer as a stratigraphic marker, indicate that short-term (∼50 years) rates are as much as an order of magnitude higher than the long-term (1000s of years) rates. We suggest that the marsh's geologic setting in an incised river valley with steep vertical constraints and a large fluvial discharge, promotes rapid accretion rates, with rates accelerating as the sea moves inland, due to extended hydroperiods and the input of clastic material from both the marine and terrestrial sides. These rates are especially large when compared to accretion occurring in the more common open marshes fringing the Gulf that lack fluvial input. The difference is particularly large when related to marsh recovery/regrowth following the deposition of thick hurricane-generated clastic layers. Given the number of similar incised river valleys along the Gulf Coast, we believe that understanding the processes controlling marsh accretion in such environments is essential in evaluating marsh sustainability on a regional basis.

“…Sediment records collected in these environments often show coarse-grained layers interbedded with finer-grained, organic-rich autochthonous sediments, where the sand can be interpreted as hurricane-induced event beds (Wallace et al 2014).Variety of proxies allows to distinguish a storm record and this can be done for example through foraminifera (Polovodova Asteman et al 2013;Strotz et al 2016), diatom (Szkornik et al 2008) or pollen analysis (Caseldine et al 2005;Tisdall et al 2013) along with isotopic geochemistry (Das et al 2013;Heyng et al 2012;Sabatier et al 2010). Equally important are studies of internal landform architecture (Vilumaa et al 2016), grainsize (Feal-Perez et al 2014;Klostermann et al 2014;Peros et al 2015;Toomey et al 2013), mineralogy (Klostermann and Gischler 2015) and the character of quartz grains (Björck and Clemmensen 2004;Costa et al 2012;Costas et al 2012).…”

Sediment record collected from the coastal lake serves as a powerful tool for reconstructing changes in palaeoenvironment and understanding the potential signals of past storminess. In this study, we use several proxies from sediment of the Holocene Thermal Maximum at coastal Lake Lilaste, Latvia. We focus on surface texture of quartz grains from the mineral inorganic fraction as indicators of depositional environments. We then use this as a proxy for potential storm transport and combine with information on granulometry, diatom stratigraphy and chronology to answer the question whether flux of quartz grains in the lake originated from the sea or from the land. Analyses in a binocular and scanning electron microscope reveal that most of the investigated quartz grains originate from dwelling in the seawater and wave action in the nearshore zone. Grains representing very energetic subaqueous environment similar to storm events are also present. Terrestrial record is of minor significance and visible through occurrence of aeolian quartz grains.

“…These fields of research were successfully applied in the western North Atlantic (Donnelly and Woodruff, 2007), northwestern Florida (Liu and Fearn, 2000;Lane et al, 2011;Das et al, 2013), the northeastern United States (Parris et al, 2010), the central Pacific (Toomey et al, 2013), southern Japan (Woodruff et al, 2009), western Australia (Nott, 2011), northeastern New Zealand (Page et al, 2010), northern Europe (Sorrel et al, 2012), or the western Mediterranean (Dezileau et al, 2011(Dezileau et al, , 2016Sabatier et al, 2012;Raji et al, 2015;Degeai et al, 2015). Such studies are still scarce in southern Tunisia, despite the importance of these topics in Mediterranean coastal areas.…”

Abstract. Climate models project that rising atmospheric carbon dioxide concentrations will increase the frequency and the severity of some extreme weather events. The flood events represent a major risk for populations and infrastructures settled on coastal lowlands. Recent studies of lagoon sediments have enhanced our knowledge on extreme hydrological events such as palaeo-storms and on their relation with climate change over the last millennium. However, few studies have been undertaken to reconstruct past flood events from lagoon sediments. Here, the past flood activity was investigated using a multi-proxy approach combining sedimentological and geochemical analysis of surfaces sediments from a southeastern Tunisian catchment in order to trace the origin of sediment deposits in the El Bibane Lagoon. Three sediment sources were identified: marine, fluvial and aeolian. When applying this multi-proxy approach on core BL12-10, recovered from the El Bibane Lagoon, we can see that finer material, a high content of the clay and silt, and a high content of the elemental ratios (Fe / Ca and Ti / Ca) characterise the sedimentological signature of the palaeo-flood levels identified in the lagoonal sequence. For the last century, which is the period covered by the BL12-10 short core, three palaeo-flood events were identified. The age of these flood events have been determined by 210 Pb and 137 Cs chronology and give ages of AD 1995 ± 6, 1970 ± 9 and 1945 ± 9. These results show a good temporal correlation with historical flood events recorded in southern Tunisia in the last century (AD 1932(AD , 1969(AD , 1979(AD and 1995. Our finding suggests that reconstruction of the history of the hydrological extreme events during the upper Holocene is possible in this location through the use of the sedimentary archives.
