Creator:: Ray, Richard D. and Egbert, Gary D.
Abstract:: How and where the ocean tides dissipate their energy are longstanding questions with both oceanographic and astronomical implications. Two decades ago, Doake suggested that flexing of Antarctic ice shelves by the underlying ocean tide is an important energy sink, perhaps accounting for over half the global dissipation rate. Observational constraints...

Abstract:: We assimilate localized mass anomalies inferred from GRACE ranging measurements into a hydrodynamic model to improve tidal solutions around Antarctica for the M2, S2, and O1 constituents. The variational approach used accounts for the spatial averaging of tidal elevations implicit in the mass anomaly parametrization used for the GRACE tidal...

Creator:: Vincent, P., Buckley, S. M., Yang, D., and Carle, S. F.
Abstract:: Anomalous uplift is observed at the Lop Nor, China nuclear test site using ERS satellite SAR data. Using an InSAR time‐series analysis method, we show that an increase in absolute uplift with time is observed between 1997 and 1999. The signal is collocated with past underground nuclear tests. Due to...

Creator:: Harris, Robert N. and Chapman, David S.
Abstract:: We construct a mid-latitude (30° – 60° N) reduced temperature-depth profile from a global borehole temperature database compiled for climate reconstruction. This reduced temperature profile is interpreted in terms of past surface ground temperature change and indicates warming on the order of 1°C over the past 100 to 200 years....

Creator:: Kelly, S. M. and Nash, J. D.
Abstract:: Internal‐tide generation is usually predicted from local topography, surface tides, and stratification. However, internal tides are often observed to be unrelated to local spring‐neap forcing, appearing intermittently in 3–5 day bursts. Here we suggest a source of this intermittency by illustrating how remotely‐generated shoaling internal tides induce first‐order changes in...

Abstract:: The response of alongshore currents V over the continental shelf and of coastal sea level ζ along the Pacific coast of North America to atmospheric forcing on large alongshore scales (100-2000 km) during May-July 1981 (Coastal Ocean Dynamics Experiment (CODE) 1) and May-July 1982 (CODE 2) has been studied using...

Abstract:: Temperature-depth profiles in borehole CC-I, northwestern Utah, were measured in 1978, 1990, and 1992. Borehole temperatures below 80 m depth are highly reproducible over the 14 year period indicating long term thermal stability. A slowly changing temperature field above 80 m depth has similiar characteristics to synthetic temperature profiles computed...

Abstract:: Two deep ocean hotspots of turbulent mixing were found over the Oregon continental slope. Thorpe-scale analyses indicate time-averaged turbulent energy dissipation rates of ε > 10⁻⁷ W/kg and eddy diffusivities of Kp ~ 10⁻² m²/s at both hotspots. However, the structure of turbulence and its generation mechanism at each site...

Creator:: Kelly, S. M., Jones, N. L., Nash, J. D., and Waterhouse, A. F.
Abstract:: The semidiurnal mode-1 internal tide receives 0.1-0.3 TW from the surface tide and is capable of propagating across ocean basins. The ultimate fate of mode-1 energy after long-distance propagation is poorly constrained by existing observations and numerical simulations. Here, global results from a two-dimensional semi-analytical model indicate that topographic scattering...
