Internal waves and tides in the western Weddell Sea: Observations from Ice Station Weddell

Creator:: Levine, Murray D., Padman, Laurie, Muench, Robin D., and Morison, James H.
Abstract:: The upper ocean current and temperature fields in the western Weddell Sea were measured from the drifting pack ice at Ice Station Weddell 1 (ISW) and nearby sites using a vertical profiler and an array of moored sensors in January–June 1992. These data document the structure and variability of the...

Fine structure, microstructure, and vertical mixing processes in the upper ocean in the western Weddell Sea

Creator:: Robertson, Robin, Padman, Laurie, and Levine, Murray D.
Abstract:: The upward flux of heat from the subsurface core of Warm Deep Water (WDW) to the perennially ice-covered sea surface over the continental slope in the western Weddell Sea is estimated using data obtained during February-June 1992 from a drifting ice station. Through the permanent pycnocline the diapycnal heat flux...

Tropical data assimilation experiments with simulated data: The impact of the Tropical Ocean and Global Atmosphere Thermal Array for the Ocean

Creator:: Miller, Robert N.
Abstract:: A series of observing system simulation experiments (OSSE) is performed on a simulated data set which was designed to mimic the wind-forced response of the tropical Pacific ocean. This data set was constructed by adding random perturbations to the FSU monthly mean pseudostress anomaly data. These perturbed pseudostress anomaly fields...

Snow effect on North American ground temperatures, 1950-2002

Creator:: Bartlett, Marshall G., Chapman, David S., and Harris, Robert N.
Abstract:: Changes in snow’s influence on surface ground temperature (SGT) could create a bias in the borehole temperature record of climate change. Using a snow-ground thermal model which predicts changes in the mean annual offset between SGT and surface air temperature (SAT), we calculate the response of SGT to changes in...

Wind-driven inner-shelf circulation off central Oregon during summer

Creator:: Kirincich, Anthony R., Barth, John A., Grantham, Brian A., Menge, Bruce A., and Lubchenco, Jane
Abstract:: Velocity measurements from 17 deployments of moored acoustic Doppler current profilers obtained during four summer upwelling seasons are used to describe the crossshelf divergence of Ekman transport in the inner shelf off Oregon. For each deployment the measured surface and bottom cross-shelf transports were compared with estimates of the theoretical...

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...

Currents and water masses of the coastal transition zone off Northern California, June to August 1988

Creator:: Huyer, Adriana, 1945-, Kosro, P. Michael, 1951-, Fleischbein, Jane, Ramp, Steven R., Stanton, Tim, Washburn, Libe, Chavez, Francisco P., Cowles, Timothy J., Pierce, Stephen D., and Smith, Robert L. (Robert Lloyd), 1935-
Abstract:: In summer 1988, we made repeated mesoscale surveys of a grid extending 200 km offshore between 37°N and 39°N in the coastal transition zone off northern California, obtaining continuous acoustic Doppler current profiler data and conductivity-temperature-depth data at standard stations 25 km apart on alongshore sections 40 km apart. All...

Turbulence variability at the equator in the central Pacific at the beginning of the 1991-1993 El Nino

Creator:: Lien, R.-C., Caldwell, Douglas R., Gregg, M.C., and Moum, James N.
Abstract:: A 38-day, 5990-cast microstructure study on the equator performed during the onset of the 1991-1993 El Nino shows the effect on small-scale activity at 140°W of an equatorial Kelvin wave. By using two ships, data were taken continuously from November 4 to December 12, 1991, near the National Oceanic and...

Alongshore coherence at low frequencies in currents observed over the continental shelf off Oregon and Washington

Creator:: Huyer, Adriana, 1945-, Hickey, Barbra M., Smith, J. Dungan, Smith, Robert L. (Robert Lloyd), 1935-, and Pilsbury, R. Dale
Abstract:: Current observations over the continental shelf at locations off central Oregon and southern Washington had the period from July 18 to September 18, 1972, in common. Low-frequency fluctuations (less than one cycle per day) in the currents are compared by means of visual display, linear regression, and spectral analysis. The...

Abstract:: A volcanic event of immense scale occurred within a relatively short period in early Jurassic time over large regions of the contiguous Gondwana supercontinent. In southern Africa, associated remnants of thick volcanic successions of lava flows and extensive dike and sill complexes of similar composition have been grouped together as...
