Evolution of orogenic wedges and continental plateaux: insights from crustal thermal-mechanical models overlying subducting mantle lithosphere
The links between an early phase of orogenesis, when orogens are commonly wedge shaped, and a later phase, with a plateau geometry, are investigated using coupled thermal-mechanical models with uniform velocity subduction ...

Sources of nutrients to windward agricultural systems in pre-contact Hawai'i
(Ecological Society of America, 2009-09)
Prior to European contact in 1778, Hawaiians developed intensive irrigated pondfield agricultural systems in windward Kohala, Hawai'i. We evaluated three potential sources of nutrients to windward systems that could have ...
Shipping and Seismic Exploration Noise in the Arctic Marine Soundscape: A look at Mitigation Measures for Cetaceans [graduate project].
Increasing levels of anthropogenic noise in the Arctic marine soundscape can have negative effects on cetaceans that have adapted to a relatively pristine acoustic environment and are unaccustomed to the loud, low frequency ...

High frequency acoustic observations of episodic mixing events in Lunenburg Bay
(Canadian Acoust. Assoc, 2006-12)
High frequency (0.6-5 MHz) acoustic backscatter data has been collected during the past four years (2002-2006) at Dalhousie's coastal ocean observing system at Lunenburg Bay (www.cmep.ca). Severe storm events, including ...
The Hubble Space Telescope GOODS NICMOS Survey: Overview and the Evolution of Massive Galaxies at 1.5 < z < 3
We present the details and early results from a deep near-infrared survey utilising the NICMOS instrument on the Hubble Space Telescope centred around massive M_* > 10^11 M_0 galaxies at 1.7 10^11 M_0, whereby we find an ...
The heat capacities of thermomiotic ScF3 and ScF3–YF3 solid solutions
Scandium trifluoride (ScF3) exists in a cubic ReO3 structure that exhibits negative thermal expansion from 10 to 1100 K, while substituted Sc1−x Y x F3 materials display the same behavior at room temperature but transition ...
