Dynamics of coarse woody debris following wildfire in a mountain hemlock (Tsuga mertensiana) forest

Creator:: Acker, Steven A., Kertis, Jane, Bruner, Howard, O’Connell, Kari, and Sexton, Jay
Abstract:: Coarse woody debris (CWD, comprised of snags and downed logs) is an important component of the structure and function of forest ecosystems, one which both influences the availability of fuel for wildfires and can be a result of wildfires. We studied snag persistence, and changes in mass of CWD in...

The Leeuwin Current off Western Australia, 1986–1987

Creator:: Smith, Robert L., Huyer, Adriana, Godfrey, J. Stuart, and Church, John A.
Abstract:: The Leeuwin Current in the Indian Ocean off Western Australia differs from the other major eastern boundary currents, e.g., California Current, since it flows rapidly poleward against the prevailing equatorward wind. The first large-scale study of the Leeuwin Current was conducted between North West Cape (22°S) and the south-western corner...

Geological and geochemical contraints on the isotopic composition of interstitial waters from the Hydrate Ridge region, Cascadia Continental margin

Creator:: Tomaru, A. M., Matsumoto, R., Torres, Marta E., and Borowski, Walter S.
Abstract:: The isotopic compositions of interstitial waters collected from Hydrate Ridge during Ocean Drilling Program Leg 204 were measured to evaluate the fluid evolution of this accretionary prism. At shallow depths, the dissolved Cl- concentrations and δD and δ¹⁸O values of the interstitial water reflect changes in the salinity and the...

Data report : major-element chemistry of Hole 896a glass

Creator:: Fisk, Martin R., McNeill, Andrew W., Teagle, Damon A. H., Furnes, Harald, and Bach, Wolfgang
Abstract:: Ocean Drilling Program Hole 896A (1°13.01'N, 83°43.39'W) is in 3440 m of water east of the Galapagos Platform in the equatorial eastern Pacific Ocean. At this site in 5.9 Ma crust, basement rocks were recovered over the depth range of 195.1 meters below seafloor (mbsf) to 469 mbsf. These rocks...

Paleoceanography of the Eastern Equatorial Pacific during the Neogene : synthesis of Leg 138 drilling results

Creator:: Pisias, Nicklas G., Mayer, Larry A., and Mix, Alan C.
Abstract:: The primary objective of Leg 138 was to provide detailed information about the ocean's response to global climate change during the Neogene. Two north south transects were drilled (95° and 110°W) within the region of equatorial divergence driven upwelling (and thus high accumulation rates and resolution) and spanning the major...

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...

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...

Lipid/bitumen maturation by hydrothermal activity in sediments of Middle Valley, leg 139

Creator:: Simoneit, Bernd R. T.
Abstract:: The accelerated diagenesis, maturation, and catagenesis of organic matter to hydrothermal petroleum was studied in sediments from Ocean Drilling Program Leg 139 in Middle Valley, northern Juan de Fuca Ridge. Sediments at Sites 855 and 856 have experienced high heat flow resulting in accelerated diagenesis of the immature organic matter...

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...

Causes and implications of the correlation between forest productivity and tree mortality rates

Creator:: Stephenson, Nathan L., van Mantgem, Phillip J., Bunn, Andrew G., Bruner, Howard, Harmon, Mark E., O'Connell, Kari B., Urban, Dean L., and Franklin, Jerry F.
Abstract:: At global and regional scales, tree mortality rates are positively correlated with forest net primary productivity (NPP). Yet causes of the correlation are unknown, in spite of potentially profound implications for our understanding of environmental controls of forest structure and dynamics and, more generally, our understanding of broad-scale environmental controls...
