Crustal wedging triggering recent deformation in the Andean thrust front between 31°S and 33°S: Sierras Pampeanas-Precordillera interaction

Creator:: Verges, J., Ramos, V. A., Meigs, A., Cristallini, E., Bettini, F. H., and Cortes, J. M.
Abstract:: We document a new model of crustal structure of the Andean front in Argentina where numerous historic earthquakes destroyed the cities of Mendoza in 1861 (M[subscript s] = ~7) and San Juan in 1944 (M[subscript w] = 7.0). The Cerro Salinas anticline is formed above the west directed Cerro Salinas...

Crustal fissuring on the crest of the southern East Pacific Rise at 17°15′–40′S

Creator:: Wright, Dawn J., Haymon, Rachel M., White, Scott M., and Macdonald, Ken C.
Abstract:: Fissure densities and widths have been mapped along the axial zone of the superfast spreading southern East Pacific Rise (EPR) at 17°15′–40′S with the near-bottom DSL-120 and Argo II imaging systems. We observe that the youngest lava flows (on a relative age scale) are sparsely fissured and that there is...

Intraseasonal variations of water vapor in the tropical upper troposphere and tropopause region

Creator:: Mote, Philip W., Clark, Hannah L., Dunkerton, Timothy J., Harwood, Robert S., and Pumphrey, Hugh C.
Abstract:: We show the signature of the tropical intraseasonal oscillation (TIO) in upper tropospheric moisture and dynamical fields, roughly between 200 and 100 hPa. Relationships among these fields are examined using lag-correlation analysis and using multivariate extended empirical orthogonal functions (MEEOFs), which maximize the shared explained variance among several fields for...

A modeling study of shelf circulation off northern California in the region of the Coastal Ocean Dynamics Experiment : response to relaxation of upwelling winds

Creator:: Gan, Jianping and Allen, John S.
Abstract:: A two-part modeling study of the wind-forced flow on the continental shelf off northern California in the region (37°–40°N) of the Coastal Ocean Dynamics Experiment (CODE) is pursued. This paper involves a process-oriented study with idealized wind stress forcing. Gan and Allen [2002] involves forcing with observed winds and heat...

Spectral analysis of seismic noise induced by rivers: a new tool to monitor spatiotemporal changes in stream hydrodynamics

Creator:: Burtin, A., Bollinger, L., Vergne, J., Cattin, R., and Nabelek, John L.
Abstract:: Analysis of continuous seismic data recorded by a dense passive seismological network (Hi‐CLIMB) installed across the Himalayas reveals strong spatial and temporal variations in the ambient seismic energy produced at high frequencies (>1 Hz). From June to September 2003, the high‐frequency seismic noise is observed to increase up to 20...

Spatial and temporal characteristics of the mesoscale circulation of the California Current from eddy-resolving moored and shipboard measurements

Creator:: Chereskin, T. K., Morris, M. Y., Niiler, P. P., Kosro, P. Michael, 1951-, Smith, Robert L. (Robert Lloyd), 1935-, Ramp, S. R., Collins, C. A., and Musgrave, D. L.
Abstract:: Moored observations of currents and temperatures made in the upper 600 m on eddy-resolving scales over a 2-year period are used to examine the spatial and temporal characteristics of the California Current mesoscale circulation. The observations were made at three principal longitudes: 124°W, 126°W, and 128°W in the vicinity of...

Modeling study of turbulent mixing over the continential shelf : comparison of turbulent closure schemes

Creator:: Wijesekera, H. W., Allen, John S., and Newberger, P. A.
Abstract:: The sensitivity of model-produced time-dependent wind-driven circulation on the continental shelf to the turbulent closure scheme employed is studied with a twodimensional approximation (variations across-shelf and in depth) using the Princeton Ocean Model. The level 2.5 Mellor-Yamada closure (MY), k-ε closure, and K-Profile Parameterization schemes are used to evaluate the...

Forcing a three-dimensional, hydrostatic, primitive-equation model for application in the surf zone : 1. formulation

Creator:: Newberger, P. A. and Allen, John S.
Abstract:: An Eulerian analysis for wave forcing of three-dimensional (3D) wave-averaged mean circulation in the surf zone is presented. The objective is to develop a dynamically consistent formulation for applications in a 3D primitive equation model. The analysis is carried out for the case of shallow-water linear waves interacting with wave-averaged...

Modeling of ecosystem processes on the Oregon shelf during the 2001 summer upwelling

Creator:: Spitz, Yvette, Allen, John S., and Gan, J.
Abstract:: Three-dimensional ecosystem response to wind forcing on the continental shelf off Oregon is studied using a five-component nitrogen-based ecosystem model coupled to a high-resolution circulation model. We investigate, in particular, the influence of timedependent winds and alongshore variations in shelf topography for summer 2001 during the time period of the...

Borehole temperatures and tree rings: Seasonality and estimates of extratropical Northern Hemispheric warming

Creator:: Harris, Robert N. and Chapman, David S.
Abstract:: We construct an extratropical reduced temperature–depth profile for land areas north of 20°N latitude from the global borehole temperature database compiled for climate reconstruction. The mean reduced temperature profile compares well with a time series constructed from an initial baseline temperature (0.6° ± 0.1°C) and the last 140 years of...
