Programmed emptiness : research infrastructure on the Tibetan plateau
… people, and goods, but not actually modern, as Tibetans have generally been forced to the sidelines in the development of Tibet, serving more as indigenous tourist attractions than active participants in the shaping of a modern culture. The resulting condition is a present day state that is at …

Site-specific modelling of turbulent fluxes on the Tibetan Plateau
The Tibetan Plateau attracts attention in recent decades due to its influence on the East-Asian Monsoon and regional hydrology. Therefore estimates of the regional energy and water balance have come into the focus, utilising remote sensing and regional model approaches, but such attempts require …

Aquatic macrophyte-derived biomarkers as palaeolimnological proxies on the Tibetan Plateau
The Tibetan Plateau is the largest elevated landmass in the world and profoundly influences atmospheric circulation patterns such as the Asian monsoon system. Therefore this area has been increasingly in focus of palaeoenvironmental studies. This thesis evaluates the applicability of organic …

Teleseismic tomography beneath Hi-CLIMB station array in western Tibetan Plateau
… the Hi-climb station array in mid-western Tibetan Plateau (TP), thus to understand the deformation scheme of the Indian-Eurasian collision. The Hi-Climb seismic array, which includes 75 seismic stations, was collecting data from late 2002 to 2005. It forms a nearly linear shape extending …

Reconstructing climate variability on the Tibetan Plateau : comparing aquatic and terrestrial signals
… temperature and moisture patterns across the Tibetan Plateau are very complex. The onset and magnitude of the Holocene climate optimum in the Asian monsoon realm, in particular, is a subject of considerable debate as this time period is often used as an analogue for recent global warming. In …

Structural, thermal, and geomorphic evolution of the eastern margin of the Tibetan Plateau
The eastern margin of the Tibetan Plateau adjacent to and north of the Sichuan Basin poses a fundamental geodynamic problem; the topography of eastern Tibet apparently developed in the absence of significant shortening of the upper crust. This study investigates the development and subsequent …

Seismic attenuation of regional phases in the northern Middle East and the Tibetan Plateau
… zones, the northern Middle East and the Tibetan Plateau. The regional phase Q is typically assumed as the intrinsic Q, whose lateral variation suggests temperature structure of the crust and the uppermost mantle. In the northern Middle East, large varations in regional phase Q models are …

Eddy-covariance measurements as a tool for ecological and hydrological studies on the Tibetan Plateau
The environment of the Tibetan Plateau (TP) is regarded as one of the most sensitive ecosystems of the world. However, investigations on effects caused by global climate change or anthropogenic activities are rare due to its quite remote location. This thesis deals with various aspects of the …

Orbital Forcing of Late Miocene-Pleistocene Environmental Change in the Zhada Basin, SW Tibetan Plateau
… sediments in the Zhada Basin, southwestern Tibetan Plateau. The Zhada Basin lies near the northern extent of modern ISM precipitation where moisture-bearing ISM air masses mix with dry westerly air masses, and thus the basin is sensitive to strengthening or weakening of the ISM. Major …

Assessment of Black Carbon in Snow and Ice from the Tibetan Plateau and Pacific Northwest
<p>An ice core from Mt. Geladandong, Tibetan Plateau, spanning 1853-1983, and snow samples collected over two winters from the Cascade Mountains were analyzed for concentrations of black carbon (BC) using a Single Particle Soot Photometer (SP2). From the ice core, the high-resolution BC record …

Seismic characterization of fractured reservoirs (part I) ; Crustal deformation in the Tibetan Plateau (part II)
… (2) to understand the tectonic evolution of the Tibetan plateau and the basic processes that control its deformation. A 3-D, large-scale analytical model is used to model continental crustal deformation in the Tibetan plateau. The idealized crust is assumed to consist of two layers, an upper …

Evolution of upper mantle beneath East Asia and the Tibetan Plateau from P-wave tomography
… of the upper mantle beneath East Asia and the Tibetan Plateau through high resolution P-wave tomography. The approach to high resolution tomography is based on (i) the combined use of a large range of different types of seismic data, (ii) the use of approximate finite frequency sensitivity …

High-Resolution Modelling of Surface-Atmosphere Interactions and Convection Development at Nam Co Lake, Tibetan Plateau
The Tibetan Plateau has recently become an area of increased interest for the atmospheric and environmental sciences. Surface-atmosphere interactions and specifically the exchange of momentum, turbulent energy and water vapour as well as the development of convection are not only important for the …

Crustal structure beneath hi-climb seismic array in western Tibetan plateau from a generalized H-κ method
… dense Hi-CLIMB seismic array in western-central Tibetan Plateau, which covered Yarlung-Zangpo Suture (YZS) and Bangong-Nujiang Suture (BNS) linearly along approximately 85°E. With the improved H value, we can better interpret both past and present tectonic settings of the region, as improved κ …

SEISMIC VELOCITY, RADIAL ANISOTROPY IN THE CRUST AND UPPER MANTLE OF NORTHEASTERN TIBETAN PLATEAU FROM SURFACE WAVE TOMOGRAPHY
The northeastern (NE) Tibetan Plateau with complex interaction between mountain building and strike-slip faulting is a prime site to study the growth of the plateau and to understand the dynamic processes at its boundaries. This dissertation research investigates the crust and upper mantle …

Late glacial to Holocene climate and vegetation changes on the Tibetan Plateau inferred from fossil pollen records in lacustrine sediments
… climate in central Asia, and especially on the Tibetan Plateau (TP), is of great importance for an understanding of global climate processes and for predicting the future climate. As a major influence on the climate in this region, the Asian Summer Monsoon (ASM) and its evolutionary history are …

Dissecting the eastern margin of the Tibetan plateau : a study of landslides, erosion and river incision in a transient landscape
The eastern margin of the Tibetan plateau is characterized by large rivers dissecting regional topography that has been uplifted in association with the continued convergence of the Indian subcontinent and Eurasia. In this thesis, I utilize field observations, digital topographic data, cosmogenic …
