The transient response of bedrock river networks to sudden base level fall
… ranges and the tempo of sediment delivery to depositional basins. As this incision signal propagates through the river network, its upstream extent is often recognized as a discrete, steep convexity in the channel profile, defined here as a knickpoint. In this thesis, theoretical, numerical, …

Late glacial and Holocene marine geology, palaeoceanography and palaeoecology of the Northern Isles of Scotland
… marine sediment cores were recovered from depositional basins around Shetland and Orkney, UK. Using palaeoenvironmental datasets generated from these cores (foraminiferal assemblages, stable isotopes, sediment physical properties, ITRAX XRF, grain size, and total organic carbon) this thesis …

Hypsometric and geometric controls on hydrodynamics, tidal asymmetry, and sediment connectivity in shallow estuarine systems
Estuaries and tidal basins are highly dynamic coastal systems that serve as a transition zone between the river and the ocean. The morphological evolution of these diverse environments is modulated by non-linear feedbacks between tides, meteorological forcing, and sediment transport processes. This …

Paragenesis of Lacustrine Microbialites in the Upper Wilkins Peak Member, Green River Formation, Wyoming
<p>Microbialites from the upper Wilkins Peak Member were investigated to determine their paragenesis and to help interpret lake chemistry. Two specific microbialite beds were analyzed that are associated with the “layered tuff”. Samples were collected from correlated sections along a NW to SE, 24 …
