Investigation of the Cape Fear arch and East Coast fault system in the Coastal Plain of North Carolina and northeastern South Carolina, USA, using LiDAR data

LiDAR data collected in the Coastal Plain of the Carolinas revealed numerous, mostly NW-SE-oriented lineaments that cross the Cape Fear arch, the longest of which are the 50- to 115-km-long, NW-SE-oriented Faison, Jarmantown, Livingston Creek, and White Marsh lineaments and the ~50-km-long, ENE-WSW-oriented Tomahawk lineament in southeastern North Carolina. Their interpretation is based mainly on locally incised channels, abrupt stream bends, topographic scarps, and linear areas of uplifted Coastal Plain sediments. The Precambrian to Paleozoic Graingers basin or synform in the pre-Cretaceous basement terminates to the southwest along the ~28-km-long, 3- to 7-km-wide Jarmantown high. The ~115-km-long Jarmantown lineament may be the surface expression of the previously reported Neuse fault, the location of which has been controversial. The Jarmantown and other lineaments crossing the Cape Fear arch suggest that the arch is structurally complex. Further investigation of the East Coast fault system (ECFS) along the west side of the Cape Fear arch in North Carolina revealed that it is located farther to the northwest than previously reported, thereby making it continuous with the ECFS in northeastern South Carolina where it forms a ~15° restraining bend. We postulate that the interpreted faults crossing the Cape Fear arch in southeastern North Carolina formed to compensate for the increased compression and change in volume from dextral motion along the fault bend. Holocene paleoliquefaction deposits near the coast, a vertically offset Pleistocene(?) beach ridge along the interpreted Faison fault, and Tertiary surface faults along the ECFS northeast of Smithfield, North Carolina, suggest that large Quaternary earthquakes may have occurred along the ECFS, the Faison and Neuse faults, and other interpreted faults that cross the Cape Fear arch.

Torn Between Boundaries: Bodies-in-Pain, Christianity and Feature Film

<p>The central argument of this dissertation, contrary to the secularisation thesis which predicts the decline of Christianity, is that Christian-inspired values tacitly influence embodied experience. Crossing disciplinary boundaries, various theoretical perspectives and empirical studies, the case of bodies-in-pain is used as the focus for empirical analysis. This study draws heavily on Mellor and Shilling's (1997) ideal-type analysis of Medieval Catholic and early Modern Protestant forms of embodied sociality and knowledge to produce an original model of bodies-in-pain. This model is then used as a comparative heuristic tool to assess to what extent bodies-in-pain can be identified as communicating meaning in the 'reel world' of fiction films. Three films that on the surface do not appear to have explicit Christian motivation are chosen for detailed examination. These are: Se7en (1995), Minority Report (2002) and Cape Fear (1991). The final chapter relates the bodies-in-pain models to a pre-existing audience response study focused on Cronenberg's film Crash (1996) to indicate what it is about the body that allows it to be depicted and constructed in certain ways. Overall this dissertation departs from the idea that Christianity must be at odds with secular society, instead, secularisation is reframed as a catalyst for social change that does not mean the end of Christian influence in society. In light of this, I claim Christianity remains socially and institutionally significant for contemporary Western people and the way in which they make sense of the body.</p>

Rapid-response observations on barrier islands along Cape Fear, North Carolina, during Hurricane Isaias

Hurricane Isaias struck the Cape Fear Region of North Carolina around 23:00 EDT on 3 August 2020, making landfall at Ocean Isle Beach as a Category 1 storm with peak wind speeds of 80 mph. An array of nearshore Sofar Spotter wave buoys captured the wave field at two beaches off the coasts of Bald Head Island (south-facing and east-facing beaches) and Masonboro Island. Local variations in significant wave height and peak wave direction were observed along the Lower Cape Fear Region, due to large shoal features impacting the regional wave climate. A cross-shore transect of five pressure sensors was installed at the north end of Masonboro Island 2.5 days prior to landfall to measure storm surge, wave runup, and variation of gravity/ infragravity wave energy across the barrier island. The three fast-sampling wave gauges along the backshore became buried before Hurricane Isaias peak storm surge, and the two gauges on and behind the dune were never inundated. A low-cost (< $250) Storm Surge Observation Camera (SSOC) prototype captured storm surge and coastal erosion at Kure Beach, in conjunction with pre- and post-storm RTK GPS beach profile surveys. Kure Beach experienced more than 1.0 m of vertical erosion of the berm, while Masonboro Island experienced around 0.1 m of accretion across the backshore, despite nearly identical wave and wind forcing conditions at the two beaches separated by ~20 km. Pre-storm berm height and width (higher and wider at Kure Beach), as well as foreshore slope (steeper, 1:9, at Kure Beach), are likely factors influencing significant erosion at Kure Beach, while slight accretion was observed at Masonboro Island.

Nogueira-pecã em sistema agroflorestal

Os sistemas agroflorestais biodiversos são uma estratégia de manejo do solo que busca promover interações benéficas entre componentes bióticos e abióticos. A nogueira-pecã é uma espécie arbórea de ciclo longo e de grande porte, que influenciará de maneira decisiva os sistemas que ela integra. O objetivo deste trabalho é estabelecer padrões de comportamento das cultivares de nogueira-pecã dentro do sistema agroflorestal. Neste experimento realizado entre 2015 e 2017, a cultivar foi o fator de variação avaliado, sendo considerados quatro tratamentos: ‘Barton’, ‘Cape Fear’, ‘Desirable’ e ‘Shawnee’. As variáveis analisadas foram: altura e diâmetro das plantas; número de gemas por ramo; número de ramos; diâmetro e comprimento de ramo e números de folhas por ramo; área foliar; número de folíolos, peso fresco e seco; número de racimos e flores; inflorescências e ataque de formiga. Com relação ao comportamento reprodutivo, a cultivar Barton apresentou uma dicogamia do tipo protândrica, ‘Cape Fear’ oscilou o comportamento, demonstrando-se protogínica na primeira safra e protândrica na seguinte. ‘Barton’ e ‘Cape Fear’ demonstraram melhor desempenho reprodutivo do que ‘Desirable’ e ‘Shawnee’ em sistemas agroflorestais, porém, requer-se estudos que incluam a fase reprodutiva e considere outras cultivares.

Hillslope Erosion Mitigation: An Experimental Proof of a Nature-Based Solution

Soil erosion during rainfall events is affected by several factors, such as topography, soil type, land management, and vegetation cover. In this study, a series of tests investigates the influence of selected perennial herbaceous plants with a deep and strong rooting system, called MC1, on runoff generation and soil erosion. The tests on the investigated nature-based solution have been performed in the Cape Fear experimental hillslope with natural and artificial rainfall and for different vegetation heights. For all the experiments, runoff, soil moisture, and erosion data were observed and collected. The results obtained in this study suggest the following conclusions: (1) MC1 is effective in terms of soil erosion reduction already with a minimum vegetation height equal to 30 cm; (2) MC1 maximum efficiency, in terms of soil loss reduction, has been reached for a vegetation height equal to 70 cm; (3) In terms of the eroded material, the use of MC1 allows for a reduction of soil loss up to 300 times higher than the bare soil condition; (4) The use of MC1 allows for a reduction in the runoff coefficient up to 1/3 of the corresponding value in the bare soil condition.
