Depositional And Deformational Structures In Three 'Esker-Like' Ridges, Southwestern Ontario, John D. Parish Jan 1990

Depositional And Deformational Structures In Three 'Esker-Like' Ridges, Southwestern Ontario, John D. Parish

Theses and Dissertations (Comprehensive)

The Dundalk Till Plain in southwestern Ontario is crossed by five “esker-like” ridges, believed to have been formed simultaneously during the early stage of the mid-Port Burce Stadial. The three middle ridges are the focus of this research, with each ridge having a different topographic form, but the length of, and distance between, ridges are similar. Occurrences of differing depositional structures and the presence of deformational structures over short lateral and vertical distances reveal the complexity of processes involved. The dominant primary sedimentary structures are large-scale tabular cross-beds. Many individual cross-beds are composed of poorly sorted, matrix-supported gravels. High variability …


Calibration Of A General Optical Equation For Remote Sensing Of Suspended Sediments In A Moderately Turbid Estuary, Richard P. Stumpf, Jonathan Pennock Oct 1989

Calibration Of A General Optical Equation For Remote Sensing Of Suspended Sediments In A Moderately Turbid Estuary, Richard P. Stumpf, Jonathan Pennock

School of Marine Science and Ocean Engineering

Abstract

A general algorithm for determining suspended sediment concentrations in the surface waters of estuaries has been developed for use with satellite data. The algorithm uses a three-parameter general optical equation to relate suspended sediment concentrations to water reflectances that have been corrected for sun angle effects, atmospheric path radiance, and tidal excursion. Using data collected by the advanced very high resolution radiometer on five different dates, reflectances were determined using two different methods, one providing maximum correction for haze and the other providing minimum sensitivity to pigments. For both methods, in situ and remotely sensed samples from Delaware Bay …


A Revision Of The North American Papillose Allocreadiidae (Digenea) With Independent Cladistic Analyses Of Larval And Adult Forms, Janine N. Caira Oct 1989

A Revision Of The North American Papillose Allocreadiidae (Digenea) With Independent Cladistic Analyses Of Larval And Adult Forms, Janine N. Caira

Bulletin of the University of Nebraska State Museum (1924–2023)

Adult specimens of all 19 North American species of papillose allocreadiids were examined. A description and figure is given for the adult of each species; details of the cirrus sacs are presented for most spesies for the first time. Descriptions were emended where necessary and judgments were made on synonymies. Scanning electron micrographs of the oral sucker of 10 species are presented as is a new key to the 19 species. A cladistic analysis was performed on the group based on adult characters. The analysis indicated that the group is monophyletic on the basis of the ventral papillae associated with …

Late-Holocene Earthflows Of The Willard Playa/Dune Complex, Estancia Valley, New Mexico: A Geomorphic Response To Climatic Change, Kurt A. Goebel Aug 1989

Late-Holocene Earthflows Of The Willard Playa/Dune Complex, Estancia Valley, New Mexico: A Geomorphic Response To Climatic Change, Kurt A. Goebel

UNLV Theses, Dissertations, Professional Papers, and Capstones

Late-middle to late Holocene dune sediment that overlies Pleistocene lacustrine sediment marks the onset of xeric conditions in the Estancia Valley, central New Mexico. Incised into the underlying lacustrine sediments, the modern deflation basins are enclosed by parabolic dunes composed of clay and gypsum derived from the underlying sediment.

Located on the in-facing dune slopes of the deflation basins, the most striking geomorphic feature of this dune complex are numerous elongated scars. These relict scars document a geomorphically distinct earthflow event. Arroyos that cut into flow scars expose eolian earthflow sediment overlying lacustrine deposits. In the zone of depletion, erosional-flow …

Pisces Iv Submersible Observations In The Epicentral Region Of The 1929 Grand Banks Earthquake, John E. Hughes Clarke, Larry A. Mayer, David J.W. Piper, Alexander N. Shor

Affiliate Scholarship

The PISCES IVsubmersible was used to investigate the upper continental slope around 44 ON, 56" W, near the epicentre of the 1929 Grand Banks earthquake. Four dives in water depths of 800-2000 m were undertaken to observe speci3c features identijied with the SeaMARC I sidescan system in 1983. Two dives were made in the head of Eastern Valley where pebbly mudstones ofprobable Pleistocene age were recognized outcropping on the seafloor. Constructional features of cobbles and boulders, derived by exhumation and reworking of the pebbly mudstone, were also observed. These include gravel/sand bedforms (transverse waves) on the valley floor. Slope failure …
