Simulation of melt pond evolution on level ice

Creator:: Skyllingstad, Eric D., Paulson, Clayton A., and Perovich, Donald K.
Abstract:: A melt pond model is presented that predicts pond size and depth changes, given an initial ice thickness field and representative surface fluxes. The model is based on the assumption that as sea ice melts, fresh water builds up in the ice pore space and eventually saturates the ice. Under...

Intraseasonal variations of water vapor in the tropical upper troposphere and tropopause region

Creator:: Mote, Philip W., Clark, Hannah L., Dunkerton, Timothy J., Harwood, Robert S., and Pumphrey, Hugh C.
Abstract:: We show the signature of the tropical intraseasonal oscillation (TIO) in upper tropospheric moisture and dynamical fields, roughly between 200 and 100 hPa. Relationships among these fields are examined using lag-correlation analysis and using multivariate extended empirical orthogonal functions (MEEOFs), which maximize the shared explained variance among several fields for...

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...

Towed thermister chain observations of fronts in the subtropical North Pacific

Creator:: Samelson, Roger M. and Paulson, Clayton A.
Abstract:: A thermistor chain was towed 1400 km through the eastern North Pacific subtropical frontal zone in January 1980. The observations resolve surface layer temperature features with horizontal wavelengths of 0.2-200 km and vertical scales of 10-70 m. The dominant features, which have horizontal wavelengths of 10-100 km, amplitudes of 0.2°-1.0°C,...

Evolution of a coupled marine ice sheet-sea level model

Creator:: Gomez, Natalya, Pollard, David, Mitrovica, Jerry X., Huybers, Peter, and Clark, Peter U.
Abstract:: We investigate the stability of marine ice sheets by coupling a gravitationally self-consistent sea level model valid for a self-gravitating, viscoelastically deforming Earth to a 1-D marine ice sheet-shelf model. The evolution of the coupled model is explored for a suite of simulations in which we vary the bed slope...

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...

Variational assimilation of satellite observations in a coastal ocean model off Oregon

Creator:: Kurapov, A. L., Foley, D., Strub, P. T., Egbert, G. D., and Allen, J. S.
Abstract:: Satellite along-track sea surface height (SSH) and multisatellite sea surface temperature (SST) maps are assimilated in a coastal ocean circulation model off Oregon. The study period is June–October 2005, featuring intensive separation of the coastal upwelling jets in the eddy-dominated coastal transition zone (CTZ). The data assimilation (DA) system combines...

Abstract:: Ocean acidification is predicted to occur first in polar oceans. We investigated the saturation state of waters with respect to calcite (Wcal) and aragonite (Warg) in six sections along an Arctic outflow pathway through the Canadian Arctic Archipelago (CAA) and into the northwestern Atlantic using dissolved inorganic carbon and total...

Surface heat flux variability over the northern California shelf

Creator:: Beardsley, Robert C., Denver, Edward P., Lentz, Steven J., and Dean, Jerome P.
Abstract:: Surface heat flux components are estimated at a midshelf site over the northern California shelf using moored measurements from the 1981-1982 Coastal Ocean Dynamics Experiment (CODE) and the 1988-1989 Shelf Mixed Layer Experiment (SMILE). Time series of estimated fluxes extend from early winter through summer upwelling conditions, allowing examination of...

Benthic oxygen consumption rates during hypoxic conditions on the Oregon continental shelf: Evaluation of the eddy correlation method

Creator:: Reimers, Clare E., Özkan-Haller, H. Tuba, Berg, Peter, Devol, Allan, McCann-Grosvenor, Kristina, and Sanders, Rhea D.
Abstract:: Three stations, at ∼80 m water depth on the Oregon shelf between 44.7°N and 43.9 N, were studied under hypoxic conditions in late spring and summer of 2009 to determine benthic oxygen consumption rates. Oxygen fluxes were derived from eddy correlation (EC) measurements made from an autonomous lander deployed for...
