Phenology of particle size distributions and primary productivity in the North Pacific subtropical gyre (Station ALOHA)

Creator:: White, Angelicque E., Letelier, Ricardo M., Whitmire, Amanda L., Barone, Benedetto, Bidigare, Robert R., Church, Matthew J., and Karl, David M.
Abstract:: The particle size distribution (PSD) is a critical aspect of the oceanic ecosystem. Local variability in the PSD can be indicative of shifts in microbial community structure and reveal patterns in cell growth and loss. The PSD also plays a central role in particle export by influencing settling speed. Satellite-based...

The great 2012 Arctic Ocean summer cyclone enhanced biological productivity on the shelves

Creator:: Zhang, Jinlun, Ashjian, Carin, Campbell, Robert, Hill, Victoria, Spitz, Yvette H., and Steele, Michael
Abstract:: A coupled biophysical model is used to examine the impact of the great Arctic cyclone of early August 2012 on the marine planktonic ecosystem in the Pacific sector of the Arctic Ocean (PSA). Model results indicate that the cyclone influences the marine planktonic ecosystem by enhancing productivity on the shelves...

A mathematical framework for analysis of water tracers: Part 1: Development of theory and application to the preindustrial mean state

Creator:: Singh, H. A., Bitz, C. M., Nusbaumer, J., and Noone, D. C.
Abstract:: A new matrix operator framework is developed to analyze results from climate modeling studies that employ numerical water tracers (WTs), which track the movement of water in the aerial hydrological cycle from evaporation to precipitation. Model WT output is related to the fundamental equation of hydrology, and the moisture flux...

An observationally based constraint on the water-vapor feedback

Creator:: Gordon, N. D., Jonko, A. K., Forster, P. M., and Shell, K. M.
Abstract:: The increase in atmospheric concentrations of water vapor with global warming is a large positive feedback in the climate system. Thus, even relatively small errors in its magnitude can lead to large uncertainties in predicting climate response to anthropogenic forcing. This study incorporates observed variability of water vapor over 2002–2009...

Submesoscale streamers exchange water on the north wall of the Gulf Stream

Creator:: Klymak, Jody M., Shearman, R. Kipp, Gula, Jonathan, Lee, Craig M., D'Asaro, Eric A., Thomas, Leif N., Harcourt, Ramsey R., Shcherbina, Andrey Y., Sundermeyer, Miles A., Molemaker, Jeroen, and McWilliams, James C.
Abstract:: The Gulf Stream is a major conduit of warm surface water from the tropics to the subpolar North Atlantic. Here we observe and simulate a submesoscale (<20 km) mechanism by which the Gulf Stream exchanges water with subpolar water to the north. Along isopycnals, the front has a sharp compensated...

Permeability and pressure measurements in Lesser Antilles submarine slides: Evidence for pressure-driven slow-slip failure

Creator:: Hornbach, Matthew J., Manga, Michael, Genecov, Michael, Valdez, Robert, Miller, Peter, Saffer, Demian, Adelstein, Esther, Lafuerza, Sara, Adachi, Tatsuya, Breitkreuz, Christoph, Jutzeler, Martin, Le Friant, Anne, Ishizuka, Osamu, Morgan, Sally, Slagle, Angela, Tailing, Peter J., Fraass, Andrew, Watt, Sebastian F.

S. V., Tamura, Yoshihiko, Villemant, Benoît, Wall-Palmer, Deborah, and Wang, Fei
Abstract:: Recent studies hypothesize that some submarine slides fail via pressure-driven slow-slip deformation. To test this hypothesis, this study derives pore pressures in failed and adjacent unfailed deep marine sediments by integrating rock physics models, physical property measurements on recovered sediment core, and wireline logs. Two drill sites (U1394 and U1399)...

Sewage pollution: mitigation is key for coral reef stewardship

Creator:: Wear, Stephanie L. and Thurber, Rebecca Vega
Abstract:: Coral reefs are in decline worldwide, and land-derived sources of pollution, including sewage, are a major force driving that deterioration. This review presents evidence that sewage discharge occurs in waters surrounding at least 104 of 112 reef geographies. Studies often refer to sewage as a single stressor. However, we show...

Sand mold clamping

Creator:: Bochtler, Benedikt, Teeter, John, and Thompson, Bobby
Abstract:: EXECUTIVE SUMMARY PROJECT CONTEXT ESCO Incorporated manufactures a variety of steel parts using a sand mold casting process. In this process a clamping device is used to prevent the sand mold from leaking during the pouring process. The current clamp design has several deficiencies including an uneven distribution of the...

Displacement transfer from fault-bend to fault-propagation fold geometry: An example from the Himalayan thrust front

Creator:: Qayyum, Mazhar, Spratt, Deborah A., Dixon, John M., and Lawrence, Robert D.
Abstract:: The leading edge of the ENE-trending Himalayan thrust front in Pakistan exhibits along-strike changes in deformational style, ranging from fault-bend to fault-propagation folds. Although the structural geometry is very gently deformed throughout the Salt Range, it becomes progressively more complex to the east as the leading edge of the emergent...
