Understanding continental crust formation and modification is a fundamental and longstanding geologic problem. Influx of mantle-derived basaltic magma and partial melting of the crust are two ways to drive crustal differentiation. This process results in a low density upper crust and denser, more refractory lower crust, creating significant and vastly...

The spatial distribution and geologic histories of submarine volcanoes provide insight into submarine eruptive behavior, deep earth processes and plate tectonics. This dissertation examines the evolution of individual submarine volcanic edifices as well as linear trails of seamounts at three spatial and temporal scales.
In order to understand constructive and...

Stream-dwelling species in the U.S. southern Appalachian Mountains region are particularly vulnerable to climate change and acidification. The objectives of this study were to quantify the spatial extent of contemporary suitable habitat for acid- and thermally sensitive aquatic species and to forecast future habitat loss resulting from expected temperature increases...

The WNBA is a league that has been characterized by struggle ever since its inception in 1996. The biggest reason for nearly all of its problems lies with one source: money. The WNBA simply does not have enough money to make it a functionable professional sports league. As a result...
A 5km swath-width SeaMARC I sidescan sonar survey, conducted over
the zone of overlap between the southern rift zone of Axial Volcano and the northern
tip of the Vance spreading segment on the Juan de Fuca Ridge (between 45°24'N
and 45°50'N latitude), was analyzed to locate the present position of...
