Creator:: Dale, A. C., Levine, Murray D., Barth, John A., and Austin, J. A.
Abstract:: A fluorescent dye tracer was injected into the pycnocline on the Oregon shelf at a depth of 9–10 m. It spread rapidly cross-shelf as two distinct layers, one above the other in the water column, split by interleaving dye-free water. The vertical scale of these layers, and associated density steps,...

Creator:: Mote, Philip W. and Mantua, Nathan J.
Abstract:: Coastal upwelling helps set the physical context for marine ecosystems, and upwelling zones are among the most productive regions of the global ocean. Unlike earlier models, two state‐of‐the‐art climate models exhibit little change during the next century in the magnitude and seasonality of coastal upwelling, but climate models are still...

Creator:: Schmittner, A., Green, J. A. M., and Wilmes, S. -B.
Abstract:: Due to lower sea levels during the Last Glacial Maximum (LGM), tidal energy dissipation was shifted from the shallow margins into the deep ocean. Here using a high-resolution tide model, we estimate that global energy fluxes below 200 m depth were almost quadrupled during the LGM. Applying the energy fluxes to...

Creator:: Benoit-Bird, Kelly J., Shroyer, Emily L., and McManus, Margaret A.
Abstract:: We examined the characteristics of biological patches at four different locations to assess the relationship of patch vertical scale, amplitude, and persistence. In contrast to patches of larger animals, we found that the majority of coherent aggregations of plankton at each site were vertically compressed, with most smaller than 5m...

Creator:: Storrie-Lombardi, Michael C., Muller, J.-P., Fisk, Martin R., Griffiths, A. D., and Coates, A. J.
Abstract:: We investigate the utility of adding a 365 nm ultraviolet (UV) light source to the ExoMars panoramic camera (PanCam) scheduled for launch in 2013. The modification makes it feasible to monitor rover drill cuttings for aromatic organic molecules and provide constraints on polycyclic aromatic hydrocarbons (PAH) as a function of...

Creator:: Calvert, Andrew J., Fisher, Michael A., Ramachandran, Kumar, and Tréhu, Anne Martine
Abstract:: Seismic reflection profiles shot across the Cascadia forearc show that a 5–15 km thick band of reflections, previously interpreted as a lower crustal shear zone above the subducting Juan de Fuca plate, extends into the upper mantle of the North American plate, reaching depths of at least 50 km. In...

Creator:: Kelly, S. M., Jones, N. L., Nash, J. D., and Waterhouse, A. F.
Abstract:: The semidiurnal mode-1 internal tide receives 0.1-0.3 TW from the surface tide and is capable of propagating across ocean basins. The ultimate fate of mode-1 energy after long-distance propagation is poorly constrained by existing observations and numerical simulations. Here, global results from a two-dimensional semi-analytical model indicate that topographic scattering...

Creator:: Fetter, A., Lutjeharms, J. R. E., and Matano, Ricardo P.
Abstract:: The Agulhas Current is the western boundary current of the South Indian Ocean and is thought to play an important role in the global overturning circulation. In this study, we investigate the contribution from the wind stress field over each ocean basin of the southern hemisphere to the variability of...

Creator:: Somes, Christopher J., Schmittner, Andreas, and Altabet, Mark A.
Abstract:: Nitrogen (N) fixation by specialized microorganisms (diazotrophs) influences global plankton productivity because it provides the ocean with most of its bio-available N. However, its global rate and large-scale spatial distribution is still regarded with considerable uncertainty. Here we use a global ocean nitrogen isotope model, in comparison with δ15NO3 observations,...

Creator:: Twohy, Cynthia, Anderson, J. R., and Crozier, P. A.
Abstract:: One important role of anthropogenic aerosol particles is their influence on climate by acting as cloud condensation nuclei. However, these particles are diverse in composition and mixing state, and our knowledge of which particle types act as cloud condensation nuclei is incomplete. Here we present direct measurements of individual organic...
