Light-Absorbing Material Extracted From Cloud Droplets and Its Effect on Cloud Albedo

Creator:: Twohy, Cynthia, Clarke, A. D., Warren, S. G., Radke, L. F., and Charlson, R. J.
Abstract:: Using the counterflow virtual impactor, a new instrument for sampling cloud droplets, measurable levels of light-absorbing material were found to exist inside droplets in stratocumulus clouds off the coast of southern California. Eighty percent of the samples of droplet residue material had light absorption coefficients ranging from 6 to 20...

Constraining recent lead pollution sources in the North Pacific using ice core stable lead isotopes

Creator:: Gross, B. H., Kreutz, K. J., Osterberg, E. C., McConnell, J. R., Handley, M., Wake, C. P., and Yalcin, K.
Abstract:: Trends and sources of lead (Pb) aerosol pollution in the North Pacific rim of North America from 1850 to 2001 are investigated using a high-resolution (subannual to annual) ice core record recovered from Eclipse Icefield (3017 masl; St. Elias Mountains, Canada). Beginning in the early 1940s, increasing Pb concentration at...

Origin of the Medusae Fossae Formation, Mars: Insights from a synoptic approach

Creator:: Mandt, Kathleen E., de Silva, Shanaka L., Zimbelman, James R., and Crown, David A.
Abstract:: The geologic origin of the Medusae Fossae Formation (MFF) has remained a mystery despite three decades of research. To better constrain its formation, an in-depth analysis of observations made in the literature was combined with a new survey of over 700 Mars Orbiter Camera narrow-angle images of the MFF to...

Comparison of heat and moisture fluxes from a modified soil-plant-atmosphere model with observations from BOREAS

Creator:: Lee, Young-Hee and Mahrt, Larry
Abstract:: This study evaluates the prediction of heat and moisture fluxes from a new land surface scheme with eddy correlation data collected at the old aspen site during the Boreal Ecosystem-Atmosphere Study (BOREAS) in 1994. The model used in this study couples a multilayer vegetation model with a soil model. Inclusion...

Time-dependent, wind-driven flow over a shadow midshelf submarine bank

Creator:: Barth, John A., Pierce, S. D., and Castelao, R. M.
Abstract:: During summer 2001, high-resolution hydrographic, velocity, and bio-optical surveys were conducted over Heceta Bank off central Oregon. North of the bank, upwelling over simple bottom topography exhibited a classic response with a midshelf, baroclinic coastal jet and upwelled isopycnals. The coastal upwelling jet follows the bank topography as it widens...

In situ cosmogenic radiocarbon production and 2-D ice flow line modeling for an Antarctic blue ice area

Creator:: Buizert, Christo, Petrenko, Vasilii V., Kavanaugh, Jeffrey L., Cuffey, Kurt M., Lifton, Nathaniel A., Brook, Edward J., and Severinghaus, Jeffrey P.
Abstract:: Radiocarbon measurements at ice margin sites and blue ice areas can potentially be used for ice dating, ablation rate estimates and paleoclimatic reconstructions. Part of the measured signal comes from in situ cosmogenic ¹⁴C production in ice, and this component must be well understood before useful information can be extracted...

Effective elastic thickness of the lithosphere along the Easter Seamount Chain

Creator:: Kruse, Sarah E., Liu, Zhengrong J., Naar, David F., and Duncan, Robert A.
Abstract:: Bathymetry and gravity data collected during Legs 5, 6, and 7 of the 1993 GLORIA Expedition and the recently released 2-min altimetry-derived global gravity grid are used to determine the effective elastic thickness of the lithosphere along the Easter Seamount Chain (ESC). Forward modeling, admittance, and coherence methods yield consistent...

Spatial distributions of oxygenated organic compounds (dicarboxylic acids, fatty acids, and levoglucosan) in marine aerosols over the western Pacific and off the coast of East Asia: Continental outflow of organic aerosols during the ACE-Asia campaign

Creator:: Mochida, Michihiro, Kawamura, Kimitaka, Umemoto, Nobuhiko, Kobayashi, Minoru, Matsunaga, Sou, Lim, Ho-Jin, Turpin, Barbara J., Bates, Timothy S., and Simoneit, Bernd R. T.
Abstract:: Aerosol sampling for major oxygenated organic compounds (dicarboxylic acids, fatty acids, and levoglucosan) was conducted from 15 March to 19 April 2001 on board the National Oceanic and Atmospheric Administration R/V Ronald H. Brown over the western North Pacific, the East China Sea, and the Sea of Japan, as part...

Characterization of organic aerosols emitted from the combustion of biomass indigenous to South Asia

Creator:: Sheesley, Rebecca J., Schauer, James J., Chowdhury, Zohir, Cass, Glen R., and Simoneit, Bernd R. T.
Abstract:: Throughout South Asia biomass is commonly used as a fuel source for cooking and heating homes. The smoke from domestic use of these fuels is expected to be a major source of atmospheric particulate matter in the region and needs to be characterized for input in regional source apportionment models...

Coastal ocean response to summer upwelling favorable winds in a region of alongshore bottom topography variations off Oregon

Creator:: Castelao, Renato M. and Barth, John A.
Abstract:: Repeated mesoscale surveys of waters over the shelf and slope off Oregon were conducted during spring and summer of 2001 to study the spatial structure of the velocity and hydrographic fields. The ocean response to wind forcing is compared between a region of relatively simple topography with alongshore uniformity and...
