Evidence for atmospheric control of sea-ice motion through Nares Strait

Creator:: Samelson, Roger M., Agnew, T., Melling, H., and Munchow, A.
Abstract:: Satellite observations of ice motion are combined with model estimates of low‐level winds and surface wind stress to provide evidence for atmospheric control of sea‐ice motion through Nares Strait, between Ellesmere Island and Greenland, during two periods in 2004. The results suggest that ice flux through the strait, and its...

Transport and coastal zooplankton communities in the northern California Current system

Creator:: Bi, Hongsheng, Peterson, William T., and Strub, Paul T.
Abstract:: Alongshore transport was estimated from the gridded AVISO altimeter data and water level data from NOAA tide gauges (1993–2010) for the northern California Current (NCC) system. The biomass of the cold neritic copepods including Calanus marshallae, Pseudocalanus mimus and Acartia longiremis (dominants in the eastern Bering Sea, coastal Gulf of...

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...

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...

Abrupt thermal transition reveals hydrothermal boundary and role of seamounts within the Cocos Plate

Creator:: Fisher, A. T., Stein, C. A., Harris, Robert N., Wang, K., Silver, E. A., Pfender, M., Hutnak, M., Cherkaoui, A., Bodzin, R., and Villinger, H.
Abstract:: New thermal data from 18–24 Ma lithosphere on the Cocos Plate delineate contrasting subsurface thermal conditions in adjacent sections of crust. Heat flow through seafloor created at the East Pacific Rise is generally suppressed by ~70% relative to conductive lithospheric cooling models, whereas heat flow through adjacent, similarly-aged lithosphere generated...

Wind-driven mixing causes a reduction in the strength of the continental shelf carbon pump in the Chukchi Sea

Creator:: Hauri, Claudine, Winsor, Peter, Juranek, Laurie W., McDonnell, Andrew M. P., Takahashi, Taro, and Mathis, Jeremy T.
Abstract:: The Chukchi Sea is thought to be a globally important sink of atmospheric CO₂ due to the summertime drawdown of surface pCO₂ by phytoplankton and subsequent shelf-to-basin transport of CO₂-enriched subsurface waters into the upper halocline of the Arctic Ocean. Here we show that annually occurring storm-induced mixing events during...

Distributed subglacial discharge drives significant submarine melt at a Greenland tidewater glacier

Creator:: Fried, M. J., Catania, G. A., Bartholomaus, T. C., Duncan, D., Davis, M., Stearns, L. A., Nash, J., Shroyer, E., and Sutherland, D.
Abstract:: Submarine melt can account for substantial mass loss at tidewater glacier termini. However, the processes controlling submarine melt are poorly understood due to limited observations of submarine termini. Here at a tidewater glacier in central West Greenland, we identify subglacial discharge outlets and infer submarine melt across the terminus using...

Power-law residence time distribution in the hyporheic zone of a 2nd-order mountain stream

Creator:: Haggerty, Roy, Wondzell, Steven M., and Johnson, Matthew A.
Abstract:: We measured the hyporheic residence time distribution in a 2nd-order mountain stream at the H. J. Andrews Experimental Forest, Oregon, and found it to be a power-law over at least 1.5 orders of magnitude in time (1.5 hr to 3.5 d). The residence time distribution has a very long tail...

Uptake of NOy on wave-cloud ice particles

Creator:: Weinheimer, A. J., Campos, T. L., Walega, J. G., Grahek, F. E., Ridley, B. A., Baumgardner, D., Twohy, Cynthia, Gandrud, Bruce W., and Jensen, E. J.
Abstract:: In flight through a wave cloud during SUCCESS on 2 May 1996, simultaneous forward- and aft- facing NOy inlets were used to infer the amount of condensed-phase NOy present on ice particles that were up to a few minutes old. Condensed-phased amounts were 25-75 pptv, or 10-20% of gas-phase NOy....

Anomalous southward advection during 2002 in the Northern California current : evidence from Lagrangian Surface Drifters

Creator:: Barth, John A.
Abstract:: Equatorward velocities in the upwelling jet of the northern California Current were 0.05–0.06 m s¯¹ faster in spring and summer 2002 than on average over 1998–2002. This result is based on a five-year data set of surface drifters released across the continental margin off central Oregon (44.65°N) during April and...
