Isotopic characterization of carbon in the dissolved inorganic carbon (DIC) pool is fundamental for a wide array of scientific studies directly related to gas hydrate research. In order to generate integrated and internally consistent data of δ¹³C of DIC in pore waters from Hydrate Ridge, we used the modern continuous...
Active mountain building associated with the accretion of the Yakutat microplate (YT) in southern Alaska is characterized through the combination of a new balanced cross section and new low-temperature cooling ages. This analysis constrains the amount and timing of shortening, the spatial and temporal trends of exhumation, and the interplay...
During the upwelling season in central California, northwesterly winds along the
coast produce a strong upwelling jet that originates at Point Año Nuevo and flows
southward across the mouth of Monterey Bay. A convergent front with a mean
temperature change of 3.77 ± 0.29°C develops between the warm interior waters...
Measurements of suspended sediment concentration, velocity, salinity, and turbulent
microscale shear in the near-field region of the Columbia River plume are used to investigate
the mechanisms of sediment resuspension and entrainment into the plume. An east-west
transect was occupied during spring and neap tide periods in August 2005 and May...
The Oregon Coastal Transition Zone (OCTZ) extends several hundred
kilometers offshore where shelf flows interact with the northern California Current. A
primitive-equation numerical ocean model is used to study the upwelling circulation in this
region from 1 May to 1 November 2001. This OCTZ model obtains initial and boundary
conditions...
We analyzed 7 years (2002–2008) of micrometeorological and concurrent biological
observations of carbon and water fluxes at a mature ponderosa pine forest in central
Oregon in a semiarid climate. We sought to evaluate the extent that gross primary
productivity, net ecosystem exchange, ecosystem respiration, net primary productivity, net
ecosystem productivity,...
The connectivity among straits of the northwest Pacific marginal seas is investigated with a primitive-equation ocean circulation model simulated for 10 years from 1994 to 2003. Over the simulation interval the temporal and spatial means and variations of the model sea surface temperature are comparable to those of the satellite...
We present observations from deployments of a microstructure turbulence instrument
(the Towed Microstructure and Auxiliary Sensor Instrument) aboard a pumping profiling
vehicle (the Lamont Pumping SeaSoar) towed behind a research vessel at the New
England shelf break front in August 2002. From these we determined coincident fine-scale
vertical eddy diffusivity...
Ocean Drilling Program (ODP) Leg 202 has opened a new window
into understanding late Paleogene and Neogene global environmental
change by providing high-quality sediment sequences from a previously
unsampled region, the eastern South Pacific. Eleven sites (1232–
1242) that record variations on timescales ranging from decades to tens
of millions...
