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...

An individual-based process model to simulate landscape-scale forest ecosystem dynamics

Creator:: Seidl, Rupert, Rammer, Werner, Scheller, Robert M., and Spies, Thomas A.
Abstract:: Forest ecosystem dynamics emerges from nonlinear interactions between adaptive biotic agents (i.e., individual trees) and their relationship with a spatially and temporally heterogeneous abiotic environment. Understanding and predicting the dynamics resulting from these complex interactions is crucial for the sustainable stewardship of ecosystems, particularly in the context of rapidly changing...

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...

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. L., Stroncik, Nicole A., Aljandali, Mohammed, Boudon, Georges, Fujinawa, Akihiko, Hatfield, Robert, Kataoka, Kyoko, Maeno, Fukashi, Martinez-Colon, Michael, McCanta, Molly, Palmer, Martin, Stinton, Adam, Subramanyam, K. 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)...

Efficient Fabrication of Nanoporous Si and Si/Ge Enabled by a Heat Scavenger in Magnesiothermic Reactions

Creator:: Luo, Wei, Wang, Xingfeng, Meyers, Colin, Wannenmacher, Nick, Sirisaksoontorn, Weekit, Lerner, Michael M., and Ji, Xiulei
Abstract:: Magnesiothermic reduction can directly convert SiO₂ into Si nanostructures. Despite intense efforts, efficient fabrication of highly nanoporous silicon by Mg still remains a significant challenge due to the exothermic reaction nature. By employing table salt (NaCl) as a heat scavenger for the magnesiothermic reduction, we demonstrate an effective route to...

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...

A quantum phase transition in a quantum external field: Superposing two magnetic phases

Creator:: Rams, Marek M., Zwolak, Michael, and Damski, Bogdan
Abstract:: We study an Ising chain undergoing a quantum phase transition in a quantum magnetic field. Such a field can be emulated by coupling the chain to a central spin initially in a superposition state. We show that - by adiabatically driving such a system - one can prepare a quantum...

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...
