Approved for public release, distribution is unlimited / Expert Systems (ES) are characterized by containing the knowledge of a single human expert. Most ES today operate in a 'standalone' basis, providing expertise in a specific domain. However, managers making strategic decisions on complex topics require the coordination assessment and evaluation of knowledge from multiple human experts. Standalone knowledge bases should be loosely or tightly coupled together to form a network of coordinated ...

<p> Submarine-fan deposits form the largest sediment accumulations on Earth and host significant reservoirs for hydrocarbons. While many studies of ancient fan deposits qualitatively describe lateral architectural variability (e.g., axis-to-fringe, proximal-to-distal), these relationships are rarely quantified. In order to enable comparison of key relationships that control the lateral architecture of submarine depositional environments, I digitized published bed-scale outcrop correlation panels...

The underwater optical climate of Lake Texoma was measured at eleven fixed stations from August 1996 to August 1997. Secchi transparency and submarine photometry characterized seasonal and spatial values of secchi depth (SD), vertical attenuation coefficient (η''), and depth of euphotic zone (Zeu). Indices of Zeu:SD and η'' × SD were compared with universally applied values derived from inland and coastal waters. Turbidity explained 76% of the variation (p = 0.0001) of η'' among water quality pa...

<p> Hydrogeologically, Rapa Nui (Easter Island, Chile) is one of the least understood islands in Polynesia. There are no surface streams, the soils are poor in productivity and highly permeable, and the water table sits far below the surface of the island. One of the many mysteries of Rapa Nui is how the ancient inhabitants survived with so few sources of freshwater. </p><p> Fieldwork was conducted to identify terrestrial sources of freshwater and to evaluate the occurrence of submarine ground...

<p> The cause for low angle submarine landslide (SML) failures, at slope angles less than 4&deg;, currently cannot be readily predicted using conventional terrestrial sources (i.e. excess pore pressure, weak horizons). Numerous models that have been developed pertaining to mass wasting on continental margins generally fall into two categories: post landslide occurrence (Tsunami wave run-up modeling) on coast lines and core sample description on costal margins. To date, there has been limited res...

Turbidity currents, both continuous flow and surge-type, have been detected with acoustic sounders operating at 42.5, 107 and 200, kHz. The turbidity currents are associated with the discharge of mine tailing into Rupert Inlet. A linear relation is obtained between the backscattered acoustic signal at 200 kHz and the one-half power of suspended particulate concentration from 10 to 1000 mg 1⁻¹. This relation is consistent with Rayleigh scattering theory in form and (relative to a standard target)...

Large scale mapping in Prosser Township has revealed an entirely felsic subaqueous volcanic sequence containing both pyroclastic and effusive high silica rhyolites which are exceptionally well preserved. The eruption sequence alternates between thin coulees and tuffaceous units, all of which are covered by two distinct units, a pumice- and spatter-rich tuff breccia and a quartz porphyritic rhyolite. Aphyric coulees are well preserved, having flow banding, perlite, and hyaloclastite, which are in...

Magnetic and gravity modelling was completed along two E-W transects offshore central Oregon. These models indicate that the backstop-forming western edge of the Siletz terrane has a seaward dip of approximately 40° to 49° at 44°48'N, shallowing to ~28° at 44°1 1 'N. This is a well-determined result, given available a priori information, to a depth of ~7 km. The edge of the Siletz terrane may continue to descend at these dips to the JdF plate, but alternate geometries for the lowermost portion o...

A numerical study aimed at probabilistically assessing the coastal hazard posed by tsunamis induced by one-dimensional submarine rigid landslides that experience translational failure is presented. The numerical model here utilized is the finite-difference recreation of a linear, fully dispersive mild-slope equation model for wave generation and propagation. This recreated model has the capability to simulate submarine landslides that detach into multiple rigid pieces as failure occurs. An ad-h...

Earthquake and submarine mass failure are the most frequent causes of tsunami waves. While the process of the tsunami generation by earthquakes is reasonably well understood, the generation of tsunami waves during submarine mass failure is not. Estimates of the energy released during a tsunamigenic earthquake and respective tsunami wave draw a clear picture of the efficiency of the tsunami-generating process. However for submarine landslides, this is not as straightforward because the generatio...

U.S. Navy Submarine Approach Officers (AO) use tactical skills acquired from years at sea and a seemingly natural panache to accurately determine an enemy submarine's bearing range, course, and speed. This thesis investigates the effects of AO demographic differences and combat system employment methodologies on the ability to develop a timely and accurate firing solution. Employing a low-resolution submarine combat simulator, approximately 10 percent of the total pool of AO's were taken through...

The steep forearc slope along the northern sector of the obliquely convergent Hikurangi subduction zone is characteristic of non-accretionary and tectonically eroding continental margins, with reduced sediment supply in the trench relative to further south, and the presence of seamount relief on the Hikurangi Plateau. These seamounts influence the subduction process and the structurally-driven geomorphic development of the over-riding margin of the Australian Plate frontal wedge. The Poverty In...

The Kaikoura area is a valuable feeding spot for sperm whales with the presence of a submarine canyon close to shore. Male sperm whales can be found there year around, close to the shore and exhibiting almost constant foraging activities. This thesis investigates the distribution and habitat use, both spatially and temporally, of sperm whales (Physeter macrocephalus) within the Kaikoura submarine canyon, New Zealand. The primary aim was to determine which oceanographic variables and bathymetric ...

The fate and bioaccumulation of a contaminant entering the marine environment through wastewater outfalls depends on the contaminant’s persistence and affinity for particles. The physical characteristics of the receiving environment, e.g. current velocity, sedimentary processes, and the availability of organic carbon are also important. However, these latter effects are not usually evaluated quantitatively. This thesis investigates the near-field accumulation in sediment and biota of particle...

<p> Extreme heterogeneity in oil saturation between closely adjacent sandstone beds reflects different timing and degree of diagenesis. Understanding the distribution and origin of such heterogeneity is critical to effectively exploiting intercalated sandstone deposits within fine-grained unconventional reservoirs and in unraveling subtleties of stratigraphic traps. Sea cliff exposures at Point Fermin, California, expose a submarine channel facies within the largely hemipelagic facies. Separated...

Observations of submersible dives across Mauna Loa's submarine western flank suggest the flank has been influenced by a number of interacting processes, including large-scale sector collapses, deep volcanic spreading, and hydrothermal alteration. Subaerially derived pillow lavas observed draping the upper flank are in strong contrast to the volcaniclastic debris discovered at the toe of the flank. The distribution of rock types, deformation structures, and alteration phases within the volcanicla...

The tactical implications of submarine acoustic radiation and UNDEX- survivability have motivated the development of an advanced machinery cradle which will provide shock and vibration isolation of the submarine internals, thereby minimizing the resulting acoustic radiation. The cradle space frame must be designed and optimized for both minimum shock/vibration bi-directional transmissibility and minimum total cradle weight.

Two canyons (Juan de Fuca and Barkley) off the west coast of Vancouver Island show enhanced upwelling during the summer. Barkley Canyon is also a region of zooplankton aggregation. An intensive survey was conducted to characterize their circulation, water properties and, for Barkley, zooplankton distribution. CTD casts and zooplankton tows were performed in 1997 around Barkley Canyon. Current meter moorings were positioned within both canyons (Juan de Fuca in 1993 and Barkley in 1997). The...
