⁴⁰Ar-³⁹Ar ages of lavas from the Southeast Greenland margin, ODP leg 152, and the Rockall Plateau, DSDP leg 81

Creator:: Sinton, Christopher W. and Duncan, Robert A.
Abstract:: ⁴⁰Ar-³⁹Ar incremental heating experiments were performed on volcanic rocks recovered by drilling during Ocean Drilling Program Leg 152, southeast Greenland Margin (63°N), and Deep Sea Drilling Project Leg 81, southwest Rockall Plateau (56°N). Both of these legs drilled into thick sections of submerged lava flows, known as seaward-dipping reflector sequences,...

Geochronology of Galapagos seamounts

Creator:: Sinton, Christopher W., Christie, David M., and Duncan, Robert A.
Abstract:: Lavas from seamounts of the central Galápagos Platform and the Carnegie Ridge increase in age with distance from the western edge of the platform, consistent with a hotspot model for the generation of these features. The areal distribution of seamount ages suggests that the pattern of dispersed volcanism seen on...

Nicoya Peninsula, Costa Rica: A single suite of Caribbean oceanic plateau magmas

Creator:: Sinton, Christopher W., Duncan, Robert A., and Denyer, Percy
Abstract:: The pre-Tertiary oceanic crust exposed on the west coast of Costa Pica has been broadly referred to as the Nicoya Complex. This study was designed to determine the age of the Nicoya Complex in the Nicoya Peninsula, Playa Jaco, and the Quepos Peninsula using Ar-40-Ar-39 radiometric dating and to assess...

⁴⁰Ar/³⁹Ar geochronology of silicic and basic volcanic rocks on the margins of the North Atlantic

Creator:: Sinton, C. W., Hitchen, K., and Duncan, Robert A.
Abstract:: At the submerged margins of the North Atlantic, andesitic to dacitic and basaltic volcanic rocks occur together. The silicic rocks were derived by processes requiring the presence of continental crust (crustal anatexis and/or contamination of mafic magmas) while the majority of the basaltic lavas had little or no contact with...

Real-time data quality assessment using linear prediction

Creator:: Rentola, Christopher T. W.
Abstract:: The U.S. Air Force models many naturally occurring phenomena. To validate such models, an automated data collection system is used. Since validation is dependent upon correct data, an inexpensive method to detect erroneous data was investigated. The method uses a Wiener filter to predict values one sample in advance. If...

Subglacial hydrology of the Lake Michigan Lobe, Laurentide Ice Sheet

Creator:: Breemer, Christopher W.
Abstract:: Fast ice flow and unstable ice sheet behavior were characteristic features of the Lake Michigan Lobe of the southern Laurentide Ice Sheet. Such behavior may result from some combination of subglacial-sediment deformation and decoupled sliding at the ice-bed interface. Both mechanisms depend on high water pressure relative to ice pressure....

Influences of nitrogen on carbon dynamics in forest soil and density fractions

Creator:: Swanston, Christopher W.
Abstract:: Application of N fertilizer is a common forest management practice in the Pacific Northwest, yet the long-term influence of fertilization on forest soil properties is not well known. Although elevated N often increases mineralization of C and N from labile organic matter, negative effects have been documented in recalcitrant organic...

Nitrogen dynamics in red alder

Creator:: Swanston, Christopher W.
Abstract:: Red alder (Alnus rubra Bong.) is recognized as an important source of nitrogen to ecosystems that it inhabits. I examined N dynamics within alder trees, alder leaf litter, and the soil beneath alder leaf litter. ¹⁵Nitrogen, a stable isotope of N, was used as a tracer to follow the movement...
