Late Pleistocene Barrier-Island Sequence Along The Southern Delmarva Peninsula: Implications For Middle Wisconsin Sea Levels, Kenneth Finkelstein, Michael S. Kearney
Late Pleistocene Barrier-Island Sequence Along The Southern Delmarva Peninsula: Implications For Middle Wisconsin Sea Levels, Kenneth Finkelstein, Michael S. Kearney
VIMS Articles
Evidence for a middle Wisconsin sea-level high at or above modern limits along the east coast of the United States has long been controversial. Most reports have been dismissed as poorly dated or lacking unequivocal documentation of a marine transgression. We describe here a 14C-dated, middle Wisconsin transgressive sequence with an extant subaerial barrier facies along the southern Delmarva Peninsula. This sequence indicates that sea levels were near their present position between ca. 23 and 34 ka; it may correlate with other inferred similar-age littoral deposits of the area, and it suggests that the evidence for glacioeustatic fluctuations during the …
Long Wave Generation By Wave Groups In The Nearshore, Jeffrey H. List
Long Wave Generation By Wave Groups In The Nearshore, Jeffrey H. List
Dissertations, Theses, and Masters Projects
This study investigates the forcing of leaky mode long wave by incident wave groups in the nearshore. Using both field and model data, two previously proposed generation models are evaluated: the bounded long wave of Longuet-Higgins and Stewart (1964), and the breakpoint-forced long wave of Symonds et al. (1982). New methods of parameterizing incident wave height modulations are proposed, including an amplitude time series and a clearly defined groupiness factor. Cross-correlations between observed amplitude and low frequency time series clearly document the release and shoreline reflection of a group-forced long wave. The shallow water amplification of the component identified as …
Development, Test And Application Of A New Method Of Particle Shape Analyses Based On The Concept Of The Fractal Dimension, Adam Arthur Frisch
Development, Test And Application Of A New Method Of Particle Shape Analyses Based On The Concept Of The Fractal Dimension, Adam Arthur Frisch
Dissertations, Theses, and Masters Projects
Shape analysis methods based on the concept of the fractal dimension are emerging as a new method of quantifying complex particle shapes. The concept of the fractal dimension stems from the approximately linear relationship between the logarithm of the particle perimeter and the logarithm of the step length or unit of measure. as step length is shortened, the resulting particle perimeter is lengthened. The fractal dimension (D) is defined as 1 {dollar}-{dollar} b, where b is the slope of the log/log plot of perimeter against step length. Using two dimensional projected particle outlines measured by a video image digitizing system, …
