Seismic Q and Velocity Structure for the Magma-hydrothermal System of the Valles Caldera, New Mexico

The Valles Caldera lies at the intersection of the Jemez Lineament and the western edge of the Rio Grande Rift in northern New Mexico. The caldera and its immediate surroundings comprise one of the world's largest and most complex volcanic centers, with a long history of eruptive activity extending up to geologically recent times. In this thesis we present the results of two different forward m...

Deglaciated areas of Kilimanjaro as a source of volcanic trace elements deposited on the ice cap during the late Holocene

Ice fields on Kilimanjaro (5895 m a.s.l., Tanzania) are retreating and 85% of the ice cover has been lost since 1912. The degree to which this recession is exceptional during the Holocene is uncertain, as age control of the entire ice stratigraphy exists only for the very shallow and very bottom ice of the Northern Ice Field. This empirical evidence suggests that the Kilimanjaro ice cover may b...

Methyl chloride variability in the Taylor Dome ice core during the Holocene

[1] Methyl chloride (CH3Cl) is a naturally occurring, ozone-depleting trace gas and one of the most abundant chlorinated compounds in the atmosphere. CH3Cl was measured in air from the Taylor Dome ice core in East Antarctica to reconstruct an atmospheric record for the Holocene (11–0 kyr B.P.) and part of the last glacial period (50–30 kyr B.P.). CH3Cl variability throughout the Holocene is str...

Methyl chloride in a deep ice core from Siple Dome, Antarctica

[1] Methyl chloride (CH3Cl) is a naturally occurring ozone-depleting substance and a significant component of the atmospheric chlorine burden. In this study CH3Cl was analyzed in air bubbles from the West Antarctic Siple Dome deep ice core with gas ages ranging from about 65 kyr BP to the Late Holocene. CH3Cl levels were below the modern Antarctic atmospheric level of 530 ppt in glacial ice (45...
