Sustainable Urbanism, Rising Sea Level, and Green Infrastructure: New Strategies for Central London
… coastal cities to confront risks associated with rising sea level and storm water surge. This research studies flooding potentials in the greater London area, the hydrological situation of the Thames River Basin, and hybrid approaches to confronting those risks. It then explores the potentials of …

The Antarctic Peninsula ice sheet since the Last Glacial Maximum
… an important issue for quantifying post-LGM sea level rise and providing boundary conditions for General Circulation Models. Geomorphic features analyzed in multibeam swath bathymetry and seismic data from the 2002 cruise of the Nathaniel B. Palmer indicate grounded ice that was streaming up …

Late Quaternary Mississippi River Incised Valley Fill: Transgressive Depositional Packages
… Pleistocene glaciation and consequent lowered sea leve lresulted in reentrenchment of the Mississippi River incised valley. Meltwater floods from proglacial lakes incised into older deposits followed by braided fluvial (substratum) aggradation due to reduced carrying capacity after floods …

Rising Water: Harnessing the Process of Sedimentation for a Flood Resilient Coastal Landscape
This thesis examines the relationships between rising water levels, vulnerable land, and sedimentation within the Chesapeake Bay watershed. Climate induced sea level rise threatens low lying coastal land, especially in regions of continuing subsidence such as the Chesapeake Bay. Alterations to …

Establising a high-frequency standard reference sequence stratigraphy, sea-level curve, and biostratigraphy for Morrowan strata of the Lower Absaroka I time slice based upon the Bird Spring Formation, Arrow Canyon, Nevada
… by high-amplitude (100-m), high-frequency sea-level changes. Outcrop data and facies stacking patterns define 59 fifth-order fundamental cycles. These fundamental cycles stack into ten third-order sequences with an average duration of 320 ka. Changes in both cycle thickness and fundamental …

Climate and pro-glacial discharge interactions in the Pakitsoq region of Western Greenland.
… discharge substantially contributing to rising sea level. This change has occurred during a period of pronounced variability in regional climatology. However, the meteorological parameters forcing melting have not been well established, as there are few annual records of meltwater …

Sedimentological and geochemical evidence for late quaternary environmental changes in southern Africa : a case study of the mudbelt deposits off Namaqualand
… Mudbelt, South Africa. The purpose of this research is to contribute to the evidence for environmental change during the late Quaternary in the southern Africa from the analyses of continental shelf sediments and more specifically, to examine feasibility of using Namaqualand mudbelts as a key …

Analysis of a Middle Pennsylvanian Channel Complex in Pikeville, Kentucky
… subsidence. When the incised valley formed, the sea-level was low, which resulted in a sediment bypass. Subsequently, an increasing sea-level was estimated from measurements of accommodation space. With rising sea-level and increasing accommodation space, the valley fill transitioned from a …

Nearshore Sedimentology of Eroding Microtidal Estuaries: Bon Secour Bay, Alabama and Perdido Bay, Florida
… Erosion of estuarine shorelines resulting from rising sea level, storm impact, and anthropogenic influence has been increasingly evident in the microtidal Gulf Coast over recent decades. This study collects quantitative and qualitative data to better understand sedimentary dynamics associated …

Scaling Up and Exploring Marsh (SUEM)
… environmental changes such as global warming and rising sea level caused a need to study these ecosystems. Ecological problems have the specificity of being dependent on biological elements with complex interactions. New tools are therefore needed to go past biological constraints and take into …

The influence of a changing environment on the breeding biology and diet of Kelp Gulls (Larus dominicanus vetula) in Plettenberg Bay, South Africa
… systems worldwide, as well as being at risk from sea level rise. This will degrade or even destroy many feeding and breeding sites. Those species colonising new habitats in an attempt to escape rising sea level and climate change related threats, will be competing for space with the growing human …

Urban archipelago for climate change adaptation: the next phase of landmaking in Boston
… cities all over the world are threatened by sea level rise caused by global climate change. Boston is one of them that desires to seek innovative sea level rise adaptation strategies. This thesis provides a new, operational strategy that changes the relationship between water and the city, …

Spartina Alterniflora Productivity and Salt Marsh Stability Relative to Marsh Platform Elevation
… of the sediment surface and anomalies in mean sea level. Aboveground biomass, stem density, stem height and percent organic nitrogen were measured as a function of relative elevation. Marsh surface elevations were extracted from LIDAR data collected in 2003. An optimal elevation for …

Coral Reef Flood Protection and Coral Growth Typology
… stability of our cities and societies is that of rising sea level and the resulting coastal flooding. A city that has began to think of solutions is the city of Boston, pushing them to form an initiative known as “Climate Ready Boston”. The issue of both coastal and storm water flooding are …

Remembering Change: An Architectural Response to Rising Sea Levels
A rising sea level threatens historic buildings and towns that tie together the collective identity of a community, but because the disaster is often prolonged and the loss occurs all around us, the current model for memorials will not accommodate the grief the future holds. Memorials are meant to …

Controls on sedimentation in submarine canyons: Nazare, Setubal and Cascais canyons, West Iberian Margin

The Middle to Late Cretaceous microbiostratigraphy (foraminifera) and lithostratigraphy of the Cauvery Basin, Southeast India
The present research is on the Cretaceous microbio- and litho-stratigraphy of the Cauvery Basin, Southeast India. The planktonic and benthonic foraminifera are used to establish microbiostratigraphic zonations for the mid-Cretaceous succession in the Basin; leading to the first proposal of a …

Eco-engineering of coastal infrastructure: A design for life
… defences to protect infrastructure from rising sea level, erosion and stormier seas. Artificial structures are proliferating in the coastal and marine environments (“ocean sprawl”), resulting in a loss of natural habitat, species diversity and ecosystem services. To mitigate the impacts …

Sequence Stratigraphy and Petrophysics of the late Ordovician Utica-Point Pleasant Interval in the Middle Appalachian Basin, Eastern Ohio and Western Pennsylvania
… recording a period of sustained subsidence and rising sea-level along the eastern margin of North America. The transition from a carbonate-dominated system to a clastic-dominated system reflects the drowning of a widespread carbonate platform. The units of the Trenton Group and Lexington …
