TOPEX/POSEIDON tides estimated using a global inverse model

Creator:: Egbert, Gary D., Bennett, Andrew F., and Foreman, Michael G. G.
Abstract:: Altimetric data from the TOPEX/POSEIDON mission will be used for studies of global ocean circulation and marine geophysics. However, it is first necessary to remove the ocean tides, which are aliased in the raw data. The tides are constrained by two distinct types of information: the hydrodynamic equations which the...

Observations of mixed layer restratification by onshore surface transport following wind reversal in a coastal upwelling region

Creator:: Dale, Andrew C., Barth, John A., Levine, Murray D., and Austin, J. A.
Abstract:: Observations, from the Oregon continental shelf, describe the slumping of a coastal upwelling front in response to a reversal of winds from upwelling-to downwelling-favorable. Initially, the front outcropped in a surface mixed layer of depth 10–20 m with a pronounced cross-shelf density gradient. Following wind reversal, both the unbalanced cross-shelf...

Hydrographic conditions off northern Chile during the 1996–1998 La Nina and El Nino events

Creator:: Blanco, Jose Luis, Carr, Mary-Elena, Thomas, Andrew C., and Strub, P. Ted
Abstract:: The evolution of oceanographic conditions in the upwelling region off northern Chile (18°–24°S) between 1996 and 1998 (including the 1997–1998 El Niño) is presented using hydrographic measurements acquired on quarterly cruises of the Chilean Fisheries Institute, with sea surface temperature (SST), sea level, and wind speeds from Arica (18.5°S), Iquique...

The front on the northern flank of Georges Bank in spring : 1. tidal and subtidal variability

Creator:: Dale, Andrew C., Ullman, David S., Barth, John A., and Hebert, Dave
Abstract:: During March–April 1999, 2 weeks of undulating CTD and shipboard acoustic Doppler current profiler surveys revealed the variability of the intense internal tide on the northern edge of Georges Bank. The nature of the internal tide was modulated by episodic surface intrusions of cool, fresh Scotian Shelf Water (SSW), stratifying...

Pervasive mantle plume head heterogeneity: Evidence from the late Cretaceous Caribbean-Colombian oceanic plateau

Creator:: Kerr, Andrew C, Tarney, John, Kempton, Pamela D., Spadea, Piera, Nivia, Alvaro, Marriner, Giselle F., and Duncan, Robert A.
Abstract:: In SW Colombia picritic pillow lavas and tuffs, as well as breccias composed of picritic clasts, occur interspersed with basalts of the Central Cordillera and represent accreted portions of the similar to 90 Ma Colombian/Caribbean oceanic plateau (CCOP). We present new geochemical data for these picrites and high-MgO basalts from...

Evidence of nitric acid uptake in warm cirrus anvil clouds during the NASA TC4 campaign

Creator:: Scheuer, Eric, Dibb, Jack E., Twohy, Cynthia, Rogers, David C., Heymsfield, Andrew J., and Bansemer, Aaron
Abstract:: Uptake ofHNO₃ onto cirrus ice may play an important role in tropospheric NOx cycling. Discrepancies between modeled and in situ measurements of gas‐phase HNO₃ in the troposphere suggest that redistribution and removal mechanisms by cirrus ice have been poorly constrained. Limited in situ measurements have provided somewhat differing results and...

Observations of nearshore crescentic sandbars

Creator:: van Enckevort, I. M. J., Ruessink, B. G., Coco, Giovanni, Suzuki, K., Turner, I. L., Plant, Nathaniel G., and Holman, Robert A.
Abstract:: The temporal and spatial variability of crescentic sandbars is analyzed with hourly long-term (months) video observations collected at four barred sites and are qualitatively compared to the temporal and spatial variability predicted by hypotheses underpinning existing approaches and models for crescentic bar formation (edge-wave template model, linear stability analysis, and...

Examinations of ice formation processes in Florida cumuli using ice measurements of anvil ice crystal particle residues

Creator:: Prenni, Anthony J., DeMott, Paul J., Twohy, Cynthia, Poellot, Michael R., Kreidenweis, Sonia M., Rogers, David C., Brooks, Sarah D., Richardson, Matthew S., and Heymsfield, Andrew J.
Abstract:: A continuous flow diffusion chamber (CFDC) was used to measure ice formation by cloud particle residuals during the Cirrus Regional Study of Tropical Anvils and Cirrus Layers-Florida Area Cirrus Experiment. These measurements were directed toward determining the relative contributions of homogeneous nucleation, heterogeneous nucleation, and secondary ice formation processes to...

Environmental conditions required for contrail formation and persistance

Creator:: Jensen, Eric J., Toon, Owen B., Kinne, Stefan, Sachse, Glen W., Anderson, Bruce E., Chan, K. Roland, Twohy, Cynthia, Gandrud, Bruce W., Heymsfield, Andrew J., and Maike-Lye, Richard C.
Abstract:: The ambient temperatures and humidities required for contrail formation and persistence are determined from in situ measurements during the Subsonic Aircraft: Contrail and Cloud Effects Special Study (SUCCESS) experiment. Ambient temperatures and water vapor concentrations were measured with the meteorological measurement system, a laser hygrometer, and a cryogenic hygrometer (all...

Satellite-derived variability in chlorophyll, wind stress, sea surface height, and temperature in the northern California Current System

Creator:: Venegas, Roberto M., Strub, P. Ted, Beier, Emilio, Letelier, Ricardo M., Thomas, Andrew C., Cowles, Timothy J., James, Corinne, Soto-Mardones, Luis, and Cabrera, Carlos
Abstract:: Satellite-derived data provide the temporal means and seasonal and nonseasonal variability of four physical and biological parameters off Oregon and Washington (41°–48.5°N). Eight years of data (1998–2005) are available for surface chlorophyll concentrations, sea surface temperature (SST), and sea surface height, while six years of data (2000–2005) are available for...
