Physical versus biological spring transition: 2005

Creator:: Kosro, P. Michael, 1951-, Peterson, William T., Hickey, Barbara M., Shearman, R. Kipp, and Pierce, Stephen D.
Abstract:: In 2005, the onset of spring conditions in the physics of the coastal ocean (lowered sea level, spin-up of vertically-sheared equatorward coastal jet) came about 50 days later than average off Newport Oregon, on May 24. There was a further delay of 50 days before the subsurface upwelled water penetrated...

Error spectrum for the global M₂ ocean tide

Creator:: Ray, Richard D., Eanes, R. J., Egbert, Gary D., and Pavlis, N. K.
Abstract:: The most accurate determinations of the global ocean tides are currently based on altimeter measurements made by the Topex/Poseidon satellite. The error spectrum corresponding to the M₂ tidal solution is here estimated, primarily by inverse methods and secondarily by simple differencing in flatter than tidal signal spectrum, and it exceeds...

Multiple trophic levels fueled by recirculation in the Columbia River plume

Creator:: Kudela, Raphael M., Horner-Devine, Alexander R., Banas, Neil S., Hickey, Barbara M., Peterson, Tawnya D., McCabe, Ryan M., Lessard, Evelyn J., Frame, Elizabeth, Bruland, Kenneth W., Jay, David A., Peterson, Jay O., Peterson, William T., Kosro, P. Michael, Palacios, Sherry L., Lohan, Maeve C., and Dever, Edward P.
Abstract:: Large rivers represent gateways for the transport of terrigenous and anthropogenic material to the coastal ocean. Here we document a ∼700 km2 recirculation or bulge associated with the Columbia River plume that retains recently discharged river water sufficiently to create a regional bioreactor. Fueled by a fluvial nitrate source, this...

Model projections of the North Atlantic thermohaline circulation for the 21st century assessed by observations

Creator:: Schmittner, Andreas, Latif, M., and Schneider, B.
Abstract:: Most climate models predict a weakening of the North Atlantic thermohaline circulation for the 21st century when forced by increasing levels of greenhouse gas concentrations. The model spread, however, is rather large, even when the forcing scenario is identical, indicating a large uncertainty in the response to forcing. In order...

Glacial ocean overturning intensified by tidal mixing in a global circulation model

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...

Variations in Gas and Water Pulses at an Arctic Seep: Fluid Sources and Methane Transport

Creator:: Hong, Wei-Li, Torres, Marta E., Portnov, A., Waage, M., Haley, B., and Lepland, A.
Abstract:: Methane fluxes into the oceans are largely dependent on the methane phase as it migrates upward through the sediments. Here we document decoupled methane transport by gaseous and aqueous phases in Storfjordrenna (offshore Svalbard) and propose a three-stage evolution model for active seepage in the region where gas hydrates are...

Relationship of pore water freshening to accretionary processes in the Cascadia margin: Fluid sources and gas hydrate abundance

Creator:: Torres, Marta E., Teichert, B. M. A., Tréhu, Anne Martine, Borowski, W., and Tomaru, H.
Abstract:: Drilling in the Cascadia accretionary complex enable us to evaluate the contribution of dehydration reactions and gas hydrate dissociation to pore water freshening. The observed freshening with depth and distance from the prism toe is consistent with enhanced conversion of smectite to illite, driven by increase in temperature and age...

Global observations of large oceanic eddies

Creator:: Chelton, Dudley B., Schlax, Michael C., Samelson, Roger M., and de Szoeke, Roland A.
Abstract:: Ten years of sea-surface height (SSH) fields constructed from the merged TOPEX/Poseidon (T/P) and ERS-1/2 altimeter datasets are analyzed to investigate mesoscale variability in the global ocean. The higher resolution of the merged dataset reveals that more than 50% of the variability over much of the World Ocean is accounted...

Observations of internal wave packets propagating along‐shelf in northern Monterey Bay

Creator:: Woodson, C. B., Barth, J. A., Cheriton, O. M., McManus, M. A., Ryan, J. P., Washburn, L., Carden, K. N., Cheng, B. S., Fernandes, J., Garske, L. E., Gouhier, T. C., Haupt, A. J., Honey, K. T., Hubbard, M. F., Iles, A., Kara, L., Lynch, M. C., Mahoney, B., Pfaff, M., Pinsky, M. L., Robart, M. J., Stewart, J. S., Teck, S. J., and True, A.
Abstract:: Internal waves of depression were observed propagating along‐shelf and into northern Monterey Bay, California (CA) on the inner shelf. These waves had amplitudes approximately equal to the thermocline depth (∼4 m), and were unstable to shear and mix the thermocline. Isopycnal gradient spectra showed that the wave packets lead to...

Spatial patterns and trends of summertime low cloudiness for the Pacific Northwest, 1996-2017

Creator:: Dye, Alex W., Rastogi, Bharat, Clemesha, Rachel E. S., Kim, John B., Samelson, Roger M., Still, Christopher J., and Williams, A. Park
Abstract:: Summertime low clouds are common in the Pacific Northwest (PNW), but spatiotemporal patterns have not been characterized. We show the first maps of low cloudiness for the western PNW and North Pacific Ocean using a 22‐year satellite‐derived record of monthly mean low cloudiness frequency for May through September and supplemented...
