Vegetation and climate of the northwest coast of North America during the last 500 K.Y. : high–resolution pollen evidence from the northern California margin

Creator:: Heusser, Linda, Lyle, Mitchell, and Mix, Alan C.
Abstract:: Pollen analyses of sediments from Holes 1019C, 1019E, 1020C, and 1020D as well as piston Core EW9504-17 provide continuous, chronostratigraphically controlled proxy vegetation and climate data for coastal northwest North America for the last ~500 k.y. Systematic changes in the representation of the diagnostic components of northern California plant assemblages...

Subsurface temperatures beneath Southern Hydrate Ridge

Creator:: Tréhu, Anne Martine
Abstract:: During Ocean Drilling Program Leg 204, 80 in situ measurements of subseafloor temperature were made; 68 of these showed good frictional pulses on insertion and extraction from the seafloor and were used to constrain the subsurface temperature. Considering uncertainties from various sources, uncertainties in the in situ temperatures are estimated...

Seismic sequence stratigraphy and tectonic evolution of Southern Hydrate Ridge

Creator:: Chevallier, Johanna, Tréhu, Anne Martine, Bangs, Nathan Lawrence Bailey, Johnson, Joel E., and Meyer, H. Jack
Abstract:: This paper presents a seismic sequence and structural analysis of a high-resolution three-dimensional seismic reflection survey that was acquired in June 2000 in preparation for Ocean Drilling Program (ODP) Leg 204. The seismic data were correlated with coring and logging results from nine sites drilled in 2002 during Leg 204....

North-south variability in the history of deformation and fluid venting across Hydrate Ridge, Cascadia margin

Creator:: Johnson, Joel E., Goldfinger, Chris, Tréhu, Anne M., Bangs, Nathan Lawrence Bailey, Torres, Marta E., and Chevallier, Johanna
Abstract:: Hydrate Ridge is an accretionary thrust ridge located on the lower slope of the central Cascadia convergent margin. Structural mapping based on two-dimensional and three-dimensional multichannel seismic reflection profiles and gridded bathymetry coupled with deep-towed sidescan sonar data and Ocean Drilling Program (ODP) biostratigraphy suggests that seafloor fluid venting patterns...

Near-offset vertical seismic experiments during leg 204

Creator:: Tréhu, Anne Martine, Bangs, Nathan Lawrence Bailey, and Guerin, Gilles
Abstract:: Three successful vertical seismic profiles (VSPs) were acquired during Ocean Drilling Program (ODP) Leg 204 at South Hydrate Ridge. The data confirm earlier results from ocean bottom seismometer data and analysis of moveout from common midpoint reflection data that the average velocity between the seafloor and the bottom-simulating reflector (BSR)...

Millennial–scale CaCO₃ and C[subscript ORG] events along the northern and central California margins : stratigraphy and origins

Creator:: Lyle, Mitchell, Mix, Alan C., Ravelo, A. Christina, Andreasen, Dyke, Heusser, Linda, and Olivarez, Annette
Abstract:: Sediments from five Leg 167 drill sites and three piston cores were analyzed for C[subscript ORG] and CaCO₃. Oxygen isotope stratigraphy on benthic foraminifers was used to assign age models to these sedimentary records. We find that the northern and central California margin is characterized by k.y.-scale events that can...

Leg 204 synthesis : gas hydrate distribution and dynamics in the Central Cascadia accretionary complex

Creator:: Tréhu, Anne Martine, Torres, Marta E., Bohrmann, G., and Colwell, Frederick
Abstract:: Ocean Drilling Program (ODP) Leg 204 to Hydrate Ridge, located on the continental slope offshore Oregon (USA), was the first drilling expedition dedicated to understanding gas hydrate processes in accretionary complexes and provided a testbed for a number of different techniques for estimating the gas hydrate content of sediments. It...

Leg 202 synthesis: Southeast Pacific paleoceangraphy

Creator:: Tiedemann, Ralf and Mix, Alan C.
Abstract:: 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...

Late quaternary paleomagnetic secular variation and chronostratigraphy from ODP sites 1233 and 1234

Creator:: Lund, Steven P., Stoner, Joseph, and Lamy, Frank
Abstract:: During Ocean Drilling Program Leg 202, detailed shipboard paleomagnetic measurements at Sites 1233 and 1234 identified a reproducible high-resolution record of paleomagnetic secular variation (PSV) at each site. These records also contained evidence for three magnetic field excursions. This paper summarizes the complete paleomagnetic record from Site 1233 and the...

Investigation of microorganisms and DNA from subsuface thermal water and rock from the east flank of Juan de Fuca Ridge

Creator:: Fisk, Martin R., Thorseth, Ingunn H., Urbach, Ena, and Giovannoni, Stephen J.
Abstract:: During Leg 168 of the Ocean Drilling Program, basalts were recovered by drilling and subsurface water was collected with a water sampling tool at Hole 1026B on the east flank of Juan de Fuca Ridge. Microorganisms were found in both types of samples. The microorganisms in the basalt appear to...
