Abstract:: Seasonal cycles of coastal wind stress, adjusted sea level (ASL), shelf currents, and water temperatures off the west coast of North America (35°N to 48°N) are estimated by fitting annual and semiannual harmonics to data from 1981-1983. Longer records (9-34 years) of monthly ASL indicate that these two harmonics adequately...

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...

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...

Creator:: Harris, Robert N. and McNutt, Marcia K.
Abstract:: We examine variability observed in heat flow determinations collected on hot spot swells. We find substantial scatter in heat flow at wavelengths of a few hundred kilometers and less at both Hawaii and Reunion, where closely spaced data exist, and large variability in the regional heat flow surveys at Cape...

Creator:: Rienecker, Michele M. and Miller, Robert N.
Abstract:: Optimal interpolation (OI) has been used to produce analyses of quasi-geostrophic (QG) stream function over a 59-day period in a 150-km-square domain off northern California. Hydrographic observations acquired over five surveys, each of about 6 days' duration, were assimilated into a QG open boundary ocean model. Since the true forecast...

Abstract:: Temperature profiles from boreholes on the Colorado Plateau of southeastern Utah have been examined for evidence of climate change. Because these boreholes penetrate layered sedimentary rocks with different thermal conductivities, Bullard plots (temperature versus integrated thermal resistance) are used to estimate background heat flow and surface temperature intercepts. Reduced temperatures,...

Abstract:: Long-period ground surface temperature variations contained in borehole temperature-depth profiles form a complementary climate change record to high-frequency, but noisy surface air temperature (SAT) records at weather stations. We illustrate the benefits of jointly analyzing geothermal and meteorological data for two regions in Utah where both high-quality temperature-depth measurements and...

Abstract:: The southern portion of the Kodiak-Bowie seamonnt chain in the southeastern Gulf of Alaska presents a unique opportunity to investigate loading on young oceanic lithosphere. Oceanic lithosphere younger than 25 Ma is loaded both by sediments in a deep offshore trough and by seamount 100-200 km offshore. Free-air gravity anomaly...

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...
