Relative sea-level variations revealed by tide-gauge records of long duration
Trends in mean relative sea-level and pat.terns of occurrence of extreme sea levels are analyzed separately in the two parts of this thesis. In Part 1, twenty-eight of the world's longest tide-gauge records are examined for clues to the uncertain balance among factors contributing to relative …

Late Quaternary relative sea level change in the South Shetland Islands, Antarctica
… Glacial Maximum (LGM), and their contribution to sea level rise during subsequent deglaciation remains uncertain. The use of precise relative sea level (RSL) data offers great potential for inferring regional ice sheet histories, as well as helping to validate numerical models predicting future …

Relative sea level, sediment supply and barrier dynamics as driving mechanisms of Holocene coastal change.
… system behaviour by investigating the role of relative sea level, sediment supply and barrier dynamics as driving mechanisms of Holocene coastal change. The Suffolk coast, an understudied and vulnerable section of coastline in southeast England, is used as a case study to improve understanding …

Relative sea level change in the Forth and Tay Estuaries: past changes informing future trends
This thesis introduces new relative sea level datasets from the Forth and Tay Estuaries dating between 1900 and 2010 and uses these to analyse sea level oscillations, surge components and to influence future sea level projections. Prior to this research, relative sea levels had not been analysed …

Relative sea-level rise and the development of channel-fill and shallow-water sequences on Cape Cod, Massachusetts
… sequences record in some detail differing relative sea-level and sedimentation processes. Two distinct channel-fill sequences record differing sequence stratigraphies, and hence different origins and post glacial histories. These sequences have accumulated in channels eroded into two …

Keeping Pace with Relative Sea Level Rise: Marsh Platform Monitoring Shows Minimal Sediment Deficit along the Louisiana Coast
… an average 9 mm/yr subsidence rate3 and 3 mm/yr sea-level rise1, this accumulation results in a 2.7 MT/yr (3.5%) sediment mass surplus. However, there is a 0.014 km3/yr (5.4%) sediment volume deficit caused by the sediment porosity being too small to fill the accommodation space. About 20 MT/yr …

Glacial isostatic adjustment and relative sea level change over the last earthquake cycle in upper Cook Inlet, Alaska, USA
Using observations of land surface deformation, sea level change and geophysical modelling, this thesis considers the interactions of ice mass fluctuations and tectonic deformation over the last great earthquake cycle in south central Alaska. Reconstructions of relative sea level change over the …

Anatomy of a Carboniferous transgression: upper Tullig Cyclothem, County Clare, Ireland
… record the sedimentary product of cyclicity in relative sea-level on either a regional or global scale, showing both regressive and transgressive phases. This study aims to contribute to our understanding of the sedimentary consequences of relative sea-level rise in a Carboniferous transgressive …

The late holocene evolution of coastal wetlands in Argyll, Western Scotland
… has experienced differential crustal uplift and relative sea-level changes throughout the Holocene in response to glacio-isostatic adjustment. The complex interplay between land movements and relative sea-level continues to influence the morphological development of the Scottish coast. The study …

Valley Widening and the Composite Nature of Valley Margin Sequence Boundaries: Evidence from the Neilson Wash Compound Valley Fill, Cretaceous Ferron Sandstone, Utah
… chronostratigraphically significant. Current research has suggested that the sequence boundary that makes up the floor and walls of an incised valley is constantly being modified throughout the entire relative sea-level cycle. This would imply that sequence boundaries are strongly diachronous …

Quantification of Salt Marsh Carbon Stocks: Integration of Remote Sensing Data and Techniques with Field Measurements
… over large areas and have not accounted for the relatively small and scattered, though highly carbon rich, ecosystems such as mangrove swamps and salt marshes. Using data from a Spartina alterniflora dominated salt marsh in Galveston, Texas this study integrates remote sensing data (multispectral …

Sequence Stratigraphy of Campanian-Maastrichtian Strata in Eastern Alabama
… investigations have been sparse compared to research conducted in the oil rich areas down dip in the Gulf of Mexico. A sequence stratigraphic framework using the T-R cycle methodology of Embry (2002) has been established by integrating surface and subsurface lithologic data with …

Achieving integrated resilience to Coastal Flooding on the Military Installations and Surrounding Communities on the U.S. East Coast
… exposure due to its low-lying coastline, high relative sea level rise (SLR), land subsidence, and high urban densities. In addition to residential and commercial assets, many populated places also have aging critical infrastructure such as airports, fire stations, schools, roads, bridges, and …

A Palaeoecological approach to understanding the impact of coastal changes in Late Holocene societies using the Isles of Scilly as a case study
… to explore the impact of environmental changes (relative sea level increase and climate) on coastal communities and to investigate how these environmental factors controlled subsistence economies through the Holocene. The hypothesis tested was that relative sea level rise is a key factor …
