Enhanced southward flow over the Oregon shelf in 2002: a conduit for subarctic water

Creator:: Kosro, P. Michael, 1951-
Abstract:: Moored current measurements from the Oregon shelf during 1998–2003 are used to estimate time series of anomalous alongshore currents and pseudo-displacements, after accounting for the mean and seasonal cycle. From early January through mid-June, 2002, currents at 10 m were anomalously strong toward the south by an average 12 cm/s,...

Seawater intrusion through the oceanic crust and carbonate sediment in the Equatorial Pacific: Lithium abundance and isotopic evidence

Creator:: You, Chen-Feng, Chan, L.-H., Gieskes, J. M., and Klinkhammer, Gary P.
Abstract:: Large-scale lateral advection of seawater within the oceanic crust is thought to be the cause of low heat flow in the Equatorial Pacific. Until now supportive evidence is limited to reversals of B and δ¹¹B, Ca, Mg, SO₄⁻², Sr and ⁸⁷Sr/⁸⁶Sr in sediment pore waters. Here we report new evidence...

The large-scale summer circulation of the California Current

Creator:: Strub, P. Ted and James, Corinne
Abstract:: Satellite data from the Geosat altimeter and the Advanced Very High Resolution Radiometer (AVHRR) are used to show the large-scale structure of the surface circulation of the California Current System in summer. These data show the connection between an equatorward jet and temperature front off Oregon that lies within 100...

Trends in the Brazil/Malvinas Confluence region

Creator:: Combes, Vincent and Matano, Ricardo P.
Abstract:: Observations show abrupt changes in the oceanic circulation of the southwestern Atlantic. These studies report a southward drift of the Brazil/Malvinas Confluence (BMC) and a change in the spectral characteristics of the Malvinas Current (MC) transport. We address the cause of these changes using the result of a high-resolution numerical...

Altimeter estimates of anomalous transports into the northern California Current during 2000–2002

Creator:: Strub, P. Ted and James, Corinne
Abstract:: Surface transports into the California Current are calculated from TOPEX/POSEIDON altimeter surface height slopes during the 9.5 year period from October 1992–May 2002. These quantify the anomalous onshore and southward displacements of the water column during the 2000–2002 period, which had been hypothesized by others based on anomalous water properties...

Vertical heat flux and lateral mass transport in nonlinear internal waves

Creator:: Shroyer, E. L.
Abstract:: Comprehensive observations of velocity, density, and turbulent dissipation permit quantification of the nonlinear internal wave (NLIW) contribution to vertical heat flux and lateral mass transport over New Jersey’s shelf. The effect of NLIWs on the shelf heat budget was significant. On average, heat flux in NLIWs was 10 times larger...

Macondo-1 well oil-derived polycyclic aromatic hydrocarbons in mesozooplankton from the northern Gulf of Mexico

Creator:: Mitra, Siddhartha, Kimmel, David G., Snyder, Jessica, Scalise, Kimberly, McGlaughon, Benjamin D., Roman, Michael R., Jahn, Ginger L., Pierson, James J., Brandt, Stephen B., Montoya, Joseph P., Rosenbauer, Robert J., Lorenson, Thomas D., Wong, Florence L., and Campbell, Pamela L.
Abstract:: Mesozooplankton (>200 μm) collected in August and September of 2010 from the northern Gulf of Mexico show evidence of exposure to polycyclic aromatic hydrocarbons (PAHs). Multivariate statistical analysis revealed that distributions of PAHs extracted from mesozooplankton were related to the oil released from the ruptured British Petroleum Macondo-1 (M-1) well...

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...

Long-term explosive degassing and debris flow activity at West Mata submarine volcano

Abstract:: West Mata is a 1200 m deep submarine volcano where explosive boninite eruptions were observed in 2009. The acoustic signatures from the volcano’s summit eruptive vents Hades and Prometheus were recorded with an in situ (~25 m range) hydrophone during ROV dives in May 2009 and with local (~5 km...

Climate regulates alpine lake ice cover phenology and aquatic ecosystem structure

Creator:: Preston, Daniel L., Caine, Nel, McKnight, Diane M., Williams, Mark W., Hell, Katherina, Miller, Matthew P., Hart, Sarah J., and Johnson, Pieter T. J.
Abstract:: High-elevation aquatic ecosystems are highly vulnerable to climate change, yet relatively few records are available to characterize shifts in ecosystem structure or their underlying mechanisms. Using a long-term data set on seven alpine lakes (3126 to 3620 m) in Colorado, USA, we show that ice-off dates have shifted 7 days earlier over...
