Sea Beam Survey Of An Active Strike-Slip Fault: The San Clemente Fault In The California Continental Borderland, Mark R. Legg, Bruce P. Luyendyk, Jacqueline Mammerickx, Christian De Moustier, Robert C. Tyce

Center for Coastal and Ocean Mapping

The San Clemente fault, located in the California Continental Borderland, is an active, northwest trending, right-lateral, wrench fault. Sea Beam data are used to map the major tectonic landforms associated with active submarine faulting in detail unavailable using conventional echo-sounding or seismic reflection data. In the area between North San Clemente Basin and Fortymile Bank, the major late Cenozoic faults are delineated by alignments of numerous tectonic landforms, including scarps, linear trenches, benches, and sags. Character and spatial patterns of these landforms are consistent with dextral wrench faulting, although vertical offsets may be substantial locally. The main trace of the …

Magnetospheric Plasma Pressures In The Midnight Meridian: Observations From 2.5 To 35 Re, Harlan E. Spence, M. G. Kivelson, R. J. Walker, D. J. Mccomas

Physics & Astronomy

Plasma pressure data from the ISEE 2 fast plasma experiment (FPE) were statistically analyzed to determine the plasma sheet pressure versus distance in the midnight local time sector of the near-earth (12–35 RE) magnetotail plasma sheet. The observed plasma pressure, assumed isotropic, was mapped along model magnetic field flux tubes (obtained from the Tsyganenko and Usmanov [1982] model) to the magnetic equator, sorted according to magnetic activity, and binned according to the mapped equatorial location. In regions (L ≳ 12 RE) where the bulk of the plasma pressure was contributed by particles in the energy range of the FPE (70 …

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 …

Lithostratigraphy, Biostratigraphy, And Stable-Isotope Stratigraphy Of Cores From Odp Leg 105 Site Surveys, Labrador Sea And Baffin Bay, D. B. Scott, P. J. Mudie, A. De Vernal, C. Hillaire-Marcel, V. Baki, K. D. Mackinnon, F. S. Medioli, Larry A. Mayer

Affiliate Scholarship

Trigger weight (TWC) and piston (PC) cores obtained from surveys of the three sites drilled during Ocean Drilling Program (ODP) Leg 105 were studied in detail for benthic foraminiferal assemblages, total carbonate (all sites), planktonic foraminiferal abundances (Sites 645 and 647), and stable isotopes (Sites 646 and 647). These high-resolution data provide the link between modern environmental conditions represented by the sediment in the TWC and the uppermost cores of the ODP holes. This link provides essential control data for interpretating late Pleistocene paleoceanographic records from these core holes. At Site 645 in Baffin Bay, local correlation is difficult because …

The Influence Of Biogenic Silica On Seismic Lithostratigraphy At Odp Sites 642 And 643, Eastern Norwegian Sea, Peter Hempel, Larry A. Mayer, Elliot Taylor, Gerhard Bohrmann, Alan Pittenger

Affiliate Scholarship

Drilling at ODP Sites 642 and 643 revealed a 250 m-thick section of diatomaceous Pliocene to Miocene sediments on the outer Vdring Plateau, eastern Norwegian Sea. These biogenic silica-rich sediments have a significantly lower saturated bulk density than the surrounding sediments, causing a decrease in acoustic impedance, which is seismically expressed as a negative polarity reflection. Variations in sonic velocity, the other key parameter in seismic analysis, is only of secondary importance in creating impedance contrasts in our study. Synthetic seismograms were produced from shipboard physical property measurements corrected for in situ conditions. These synthetic seismograms are in good agreement …

The Influence Of Fly Ash On Obtaining Quality Plastic And Hardened Properties Of Portland Cement Concrete, Ashaari Bin Mohamad

Doctoral Dissertations

Coal fly ash produced at the Merrimack Power Station, Bow, New Hampshire was tested for chemical and physical properties. Concretes made with these fly ashes were tested for their plastic and hardened properties and compared to ordinary portland cement concrete.

An experimental test burn substituting coal with Refuse-Derived-Fuel(RDF) consisting mainly of waste paper and plastic with heating value of 6000 to 8000 BTU/lb. was done by Public Service of New Hampshire at the Merrimack Power Station. Five percent and ten percent RDF was substituted, on a BTU basis, for coal in the test burns. Twelve (12) test burn days were …

The Effect Of Reagent Rotation On Gas Phase Reactions, Judith Agnes Harrison

Doctoral Dissertations

This dissertation examines the effect of reagent rotation in elementary gas phase reactions. Historically, the effect of rotational excitation of the reagents of a chemical reaction on the reactive cross section has been poorly understood. One of the major reasons for this was the lack of a simple model in which the dynamics could be visualized. In this work, such a model is developed and utilized in order to elucidate trends in reactivity observed upon rotational excitation. Within the context of this model, exact quantum mechanical scattering calculations are performed for a simple atom-diatom system. These exact quantum mechanical probabilities …

On The Possibility Of Quasi-Static Convection In The Quiet Magnetotail, Margaret G. Kivelson, Harlan E. Spence

Physics & Astronomy

Abstract

The magnetotail is known to serve as a reservoir of energy transferred into the terrestrial magnetosphere from the solar wind. In principle, the stored energy can be dissipated impulsively, as in a substorm, or steadily through the process of steady adiabatic plasma convection. However, some theoretical arguments have suggested that quasi-static adiabatic convection cannot occur throughout the magnetotail because of the structure of the magnetic field. Here we reexamine the question. We show that in a magnetotail of finite width, downtail pressure gradients depend strongly on the ratio of the potential across half the tail to the ion temperature …

State Of The Art In Swath Bathymetry Survey Systems, Christian De Moustier

Center for Coastal and Ocean Mapping

In the last decade, advances in real-time computing and data storage capabilities have led to significant improvements in bathymetric survey systems and the single point echo-sounder has now been replaced by a variety of highresolution swath mapping sounding systems. This paper reviews the state of the art in the non-military swath bathymetry mapping systems. Such systems are typically multi narrow beam echo-sounders or interferometric side-looking sonars with swath width capabilities ranging from 0.75 to 7 times the water depth. The paper compares the design characteristics and the echo processing methods used in a number of these systems manufactured in Japan, …

Using The Bat: A Six Dimensional Mouse For Object Placement, Colin Ware, Danny R. Jessome

Center for Coastal and Ocean Mapping

Placement in space is inherently six dimensional. An object can be translated in x, y and z cartesian coordinates, and it can be rotated about three axes to change its orientation. A six dimensional sensor I\I(/S conj/gured as a one button six dimensional mouse (which we call a bat) and interfaced with an IRIS workstation thus creating an environment for investigating the problems of object placement. A sojiware workbench was built which allows the manipulation of hierarchical scenes displayed on a monitor. The features of the workbench are described together with experiences using the bat in a variety of interaction …
