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...

Creator:: Vay, S. A., Anderson, B. E., Sachse, G. W., Collins, J. E., Podolske, J. R., Twohy, Cynthia, Gandrud, Bruce W., Chan, K. Rolan, Baughcum, S. L., and Wallio, H. A.
Abstract:: We report the first measurements of CO₂, CH₄, N₂O, CO₂, and H₂O(g) in the exhaust trails of T-39, B-757, and DC-8 aircraft at cruise conditions. Emission indices (El) derived from these in-situ measurements are presented. Results are in agreement with ground-based tests indicating aircraft act as a net sink for...

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...

Abstract:: During SHEBA, thin ice and freshening of the Arctic Ocean surface in the Beafort Sea led to speculation that perennial sea ice was disappearing [McPhee et al., 1998]. Since 1987, we have collected salinity, δ¹⁸O and Ba profiles near the initial SHEBA site and, in 1997, we ran a section...

Abstract:: Measurements of stratospheric water vapor by the Microwave Limb Sounder aboard the Upper Atmosphere Research Satellite show that in the tropical lower stratosphere, low‐frequency variations are closely related to the annual cycle in tropical tropopause temperatures. Tropical stratospheric air appears to retain information about the tropopause conditions it encountered for...

Abstract:: West Mata is a 1200 m deep submarine volcano where explosive boninite eruptions were observed in 2009. The acoustic signatures from the volcano’s summit eruptive vents Hades and Prometheus were recorded with an in situ (~25 m range) hydrophone during ROV dives in May 2009 and with local (~5 km...

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...

Abstract:: Magnetotelluric (MT) data from two sites 150 and 300 km southeast of San Francisco, California (geomagnetic dipole latitude: 43 degrees, L approximately 1.9) show that the usual MT assumption of spatially uniform external magnetic fields is violated to a significant degree in the period range 10-30 s.

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...

Abstract:: Pacific winter waters, a major source of nutrients and buoyancy to the Arctic Ocean, are thought to ventilate the Arctic's lower halocline either by injection (isopycnal or penetrative) of cold saline shelf waters, or by cooling and freshening Atlantic waters upwelled onto the shelf. Although ventilation at salinity (S) >...
