Thermal effects of hydrothermal circulation and seamount subduction: Temperatures in the Nankai Trough Seismogenic Zone Experiment transect, Japan

Creator:: Spinelli, G. A. and Harris, R. N.
Abstract:: We examine the thermal effects of seamount subduction. Seamount subduction may cause transient changes in oceanic crust hydrogeology and plate boundary fault position. Prior to subduction, seamounts provide high‐permeability pathways between the basaltic crustal aquifer and overlying ocean that can focus fluid flow and efficiently cool the oceanic crust. As...

Increased dissolved terrestrial input to the coastal ocean during the last deglaciation

Creator:: Klinkhammer, Gary P., Mix, Alan C., and Haley, B. A.
Abstract:: Here we present the first downcore results for a new paleoproxy, the Mn/Ca ratio of foraminiferal calcite, applied to sediment accumulated in the extreme Eastern Tropical North Pacific (ETNP) over the last 30,000 years. The Mn/Ca results are compared to oxygen isotopes and sea surface temperature calculated from Mg/Ca. We...

Extent of the microbial biosphere in the oceanic crust

Creator:: Heberling, Cara, Lowell, Robert P., Liu, lei, and Fisk, Martin R.
Abstract:: We estimate the depth of the 120°C isotherm by constructing crustal thermal gradients based on theoretical and observed conductive heat flux as a function of lithospheric age. We chose the 120°C isotherm because it is close to the upper limit for prokaryotic life, and therefore, the isotherm approximates the maximum...

Vailulu'u Seamount

Creator:: Koppers, Anthony A. P., Staudigel, Hubert, Hart, Stanley R., Young, Craig, and Konter, Jasper G.
Abstract:: Vailulu’u seamount is an active underwater volcano that marks the end of the Samoan hotspot trail (Hart et al., 2000). Vailulu’u has a simple conical morphology (Figure 1) with a largely enclosed volcanic crater at relatively shallow water depths, ranging from 590 m (highest point on the crater rim) to...

Long-term tracking of climate change by underground temperatures

Creator:: Beltrami, Hugo, Ferguson, Grant, and Harris, Robert N.
Abstract:: Underground temperatures contain a record of past changes in the energy balance at the Earth's surface, such that borehole temperature data can be used to reconstruct long‐term trends of ground surface temperature (GST) changes. In addition to surface air temperature, however, GST is the response of the ground to other...

Nonlinear ⁴⁰Ar/³⁹Ar age systematics along the Gilbert Ridge and Tokelau Seamount Trail and the timing of the Hawaii-Emperor Bend

Creator:: Koppers. Anthony A. P., Staudigel, Hubert, Morgan, Jason Phipps, and Dunca, Robert A.
Abstract:: Over the last three decades the first-order correlation in morphology and orientation of seamount trails has been called upon to support the concept of a ‘‘fixed’’ Pacific hot spot frame of reference and to explain the Hawaii-Emperor bend (HEB) by a dramatic change in Pacific plate motion. In this paper,...

Subducted seamounts and recent earthquakes beneath the central Cascadia forearc

Creator:: Tréhu, Anne M., Blakely, Richard J., and Williams, Mark C.
Abstract:: Bathymetry and magnetic anomalies indicate that a seamount on the Juan de Fuca plate has been subducted beneath the central Cascadia accretionary complex and is now located similar to 45 km landward of the deformation front. Passage of this seamount through the accretionary complex has resulted in a pattern of...

Regional conductivity structure of Cascadia : preliminary results form 3D inversion of USArray transportable array magnetotelluric data

Creator:: Patro, Prasanta K. and Egbert, Gary D.
Abstract:: In conjunction with the USArray component of EarthScope, long period magnetotelluric (MT) data are being acquired in a series of arrays across the continental US. Initial deployments in 2006 and 2007 acquired data (10– 10,000 s) at 110 sites covering the US Pacific Northwest, distributed with the same nominal spacing...

Anomalous southward advection during 2002 in the Northern California current : evidence from Lagrangian Surface Drifters

Creator:: Barth, John A.
Abstract:: Equatorward velocities in the upwelling jet of the northern California Current were 0.05–0.06 m s¯¹ faster in spring and summer 2002 than on average over 1998–2002. This result is based on a five-year data set of surface drifters released across the continental margin off central Oregon (44.65°N) during April and...
