Low-Frequency Variability in the Stratosphere
… interaction among shortwave, high-frequency eddy thermal anomalies in the troposphere has a ""beating"" effect which emits vertically propagating low-frequency longwaves. We also see that the eddies act in such a way as to offset the effects of linear temperature advection, allowing the thermal …

Basalt Magmatism as a Key to Unlocking Cenozoic Dynamic Topography
… is to constrain the spatial and temporal thermal structure of the uppermost mantle in these regions by exploiting thermobarometric and geochemical modelling of basalts. Whole-rock samples are analysed for major, trace and rare earth elements, as well as selected radiogenic isotopes. …

Imaging of crust and mantle structures with teleseismic reflected waves
… contribution to surface topography. Although thermal anomalies are the main contribution to high elevation of the western US cordillera, our results suggest that petrological heterogeneities or dynamic forces must also play a role in mantle buoyancy. To improve mantle transition zone imaging, …

Structural Controls of the San Emidio Geothermal System, Northwestern Nevada
… and structural controls of the San Emidio geothermal system. San Emidio lies within the Basin and Range province of northwestern Nevada, ~100 km north-northeast of Reno. The San Emidio area is dominated by middle to late Miocene Pyramid sequence volcanic rocks and late Miocene to recent …

Investigations of the thermal properties of human and animal tissues
… to be usefully interpreted for detecting thermal anomalies in the human body at depths of up to several centimetres, the thermal and microwave dielectric properties of tissues must be known. This thesis is mainly concerned with the measurement and interpretation of the values of the …

Not Too Hot, Not Too Cold, But Moderately Variable: The Influence of Environmental Variability on Coral Thermal Tolerance
… these variable reef sites can increase their thermal tolerance, providing promising evidence for the ability of corals to cope with rapid climate change. This dissertation investigates the physiological and genetic response of two massive corals,<em> Porites lobata</em> and <em>Goniastrea …

Analysis of the spatio-temporal sea level variability in extreme regions using in-situ and satellite remote sensing data: South Shetland region (Antarctica)
… Orca seamount activity, were associated with thermal anomalies, while glacier meltwater discharge was linked to earlier and more variable minima at Livingston. Three phases of thermal evolution were identified over the last decade, reflecting the combined effects of regional atmospheric …

Variable Viscosity Thermal Convection at Infinite Prandtl Number in a Thick Spherical Shell
Variable viscosity thermal convection at infinite Prandtl number in a thick spherical shell is modeled using the finite element method. The discretized tensor Navier-Stokes equations are solved with the multigrid method applied to the spherical elements. Numerically convergent solutions can be …

Computer Vision Applications for Autonomous Aerial Vehicles
… such as depth cameras, lidar sensors and thermal cameras, and major breakthroughs in computer vision and machine learning fields accelerated the advance of UAV research and technology. However, due to certain unique challenges imposed by UAVs, such as limited payload capacity, unreliable …

The role of thermal history in shaping the microbiome of Red Sea corals
… this work aimed to investigate the historical thermal variability along the Red Sea and subsequently identify the relative role of coral microbiome associated with differences in coral thermal tolerance. Remotely sensed data (1982-2012) demonstrated migration of Sea Surface Temperature …

Magma genesis beneath active continental rifts
… magma genesis in the absence of significant thermal anomalies. These heterogeneous mantle domains may be linked to the complex tectonic histories of continents, which often involve multiple stages of accretion and associated recycling of materials between the crust and the mantle. In this …

Remote sensing techniques for geothermal investigation and monitoring in New Zealand
… for the investigation and monitoring of geothermal areas in the Taupo volcanic zone of New Zealand. The research and development of a helicopter-borne video thermal infrared scanner technique and associated computer image processing methods constitutes the major portion of this study. In …

Viscoelastic Strain, Viscous Rheology, and Behavior of Experimental Lava Flows
… revealing high-resolution morphologic and thermal evolution of lobes during inflation and breakout phases. These analyses revealed a consistent pattern wherein the morphologic and thermal properties seem to predict the location of a lava breakout. More specifically, areas of high internal …
