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...

A numerical study of the Magellan Plume

Creator:: Palma, Elbio D. and Matano, Ricardo P.
Abstract:: In this modeling study we investigate the dynamical mechanisms controlling the spreading of the Magellan Plume, which is a low-salinity tongue that extends along the Patagonian Shelf. Our results indicate that the overall characteristics of the plume (width, depth, spreading rate, etc.) are primarily influenced by tidal forcing, which manifests...

An optical technique for the measurement of longshore currents

Creator:: Chickadel, C. C., Holman, Robert A., and Freilich, M. H.
Abstract:: We present an optical method (optical current meter) to measure the longshore component of nearshore surface currents by measuring the alongshore drift of persistent sea foam in the surf zone. The method uses short time series of video data collected from an alongshore array of pixels. These space-time data are...

Lake-induced atmospheric circulations during BOREAS

Creator:: Sun, Jielun, Lenschow, Donald H., Mahrt, Larry, Crawford, Tim L., Davis, Kenneth J., Oncley, Steve P., MacPherson, J.I., Wang, Qing, Dobosy, Ron J., and Desjardins, R.L.
Abstract:: Lake-induced atmospheric circulations over three lakes ranging from 3 to 10 km width are analyzed using data from three aircraft during the 1994 Boreal Ecosystem-Atmosphere Study (BOREAS). A well-defined divergent lake breeze circulation is observed over all three lakes during the day. Under light wind conditions, the lake breeze is...

Oblique strike-slip faulting of the central Cascadia submarine forearc

Creator:: Goldfinger, Chris, Kulm, LaVerne D., Yeats, Robert S., McNeill, Lisa, and Hummon, Cheryl
Abstract:: At least nine WNW trending left-lateral strike-slip faults have been mapped on the Oregon-Washington continental margin using sidescan sonar, seismic reflection, and bathymetric data, augmented by submersible observations. The faults range in length from 33 to 115 km and cross much of the continental slop. Five faults offset both the...

Ocean data assimilation using optimal interpolation with a quasi-geostrophic model

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...

Introduction to special section on Recent Advances in the Study of Optical Variability in the Near-Surface and Upper Ocean

Creator:: Dickey, T., Banner, M. L., Bhandari, P., Boyd, Timothy John, 1958-2013, Carvalho, L., Chang, G., Chao, Y., Czerski, H., Darecki, M., Dong, C., Farmer, D., Freeman, S., Gemmrich, J., Gernez, P., Hall-Patch, N., Holt, B., Jiang, S., Jones, C., Kattawar, G., LeBel, D., Lenain, L., Lewis, M., Liu, Y., Logan, L., Manov, D., Melville, W.

K. P., Zaneveld, R., and Zappa, C. J.
Abstract:: Optical variability occurs in the near-surface and upper ocean on very short time and space scales (e.g., milliseconds and millimeters and less) as well as greater scales. This variability is caused by solar, meteorological, and other physical forcing as well as biological and chemical processes that affect optical properties and...

Very long period magnetotellurics at Tucson Observatory: estimation of impedances

Creator:: Egbert, Gary D., Booker, John R., and Schultz, Adam
Abstract:: Eleven years (1932-1942) of electric potential and magnetic measurement at the Tucson observatory represent a unique very long period magnetotelluric (MT) data set. We report here on a careful reanalysis of this data using modern processing techniques. We have developed and used novel methods for separating out the quasi-periodic daily...

Abstract:: Accurately simulating gross primary productivity (GPP) in terrestrial ecosystem models is critical because errors in simulated GPP propagate through the model to introduce additional errors in simulated biomass and other fluxes. We evaluated simulated, daily average GPP from 26 models against estimated GPP at 39 eddy covariance flux tower sites...

Records of geomagnetic reversals from volcanic islands of French Polynesia 2. Paleomagnetic study of a flow sequence (1.2-0.6 Ma) from the island of Tahiti and discussion of reversal models

Creator:: Chauvin, Annick, Roperch, Pierrick, and Duncan, Robert A.
Abstract:: A volcanic sequence almost 700 meters thick has been sampled in the Punaruu valley on the island of Tahiti, southern central Pacific Ocean. Detailed paleomagnetic results have been obtained from 123 sites. Three reversals are recorded in this sequence. Age determinations (K-Ar) indicate that the youngest reversal corresponds to the...
