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...

Site surveys

Creator:: Mayer, Larry A., Pisias, Nicklas G., Mix, Alan C., Lyle, Mitchell, Arason, Pordur, and Mosher, D.
Abstract:: To facilitate the selection of drill sites for Leg 138, a site survey program was conducted on board the Scripps Institution of Oceanography's research vessel Thomas Washington (Cruise Venture 1). During this cruise, which departed San Diego on 30 August 1989 and arrived in Manzanillo, Mexico, on 4 October 1989,...

Refinement of a high-resolution, continuous sedimentary section for studying Equatorial Pacific Ocean paleoceanography, Leg 138

Creator:: Hagelberg, T. K., Pisias, Nicklas G., Shackleton, N. J., Mix, Alan C., and Harris, Sara E.
Abstract:: Ocean Drilling Program (ODP) Leg 138 was designed to study the late Neogene paleoceanography of the equatorial Pacific Ocean at time scales of thousands to millions of years. Crucial to this objective was the acquisition of continuous, high-resolution sedimentary records. It is well known that between successive advanced piston corer...

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...

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 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...

Data report : spectral reflectance observations from recovered sediments

Creator:: Ortiz, Joseph D., O'Connell, Suzanne, and Mix, Alan C.
Abstract:: Sediment spectral reflectance measurements were generated aboard the JOIDES Resolution during Ocean Drilling Program Leg 162 shipboard operations. The large size of the raw data set (over 1.3 gigabytes) and limited computer hard disk storage space precluded detailed analysis of the data at sea, although broad band averages were used...

Color Reflectance Spectroscopy : a tool for rapid characterization of deep-sea sediments

Creator:: Mix, Alan C., Rugh, W., Pisias, Nicklas G., Veirs, S., and Leg 138 Scientific Party
Abstract:: During ODP Leg 138, we tested a prototype instrument, developed at Oregon State University, for measuring light reflectance in 511 channels of the visible and near-infrared bands. The technique of reflectance spectroscopy has been used for some time in chemistry and mineralogy (e.g., Hunt, 1977; Gaffey, 1986) and has found...

Biogenic and terrigenous sedimetations at Ceara rise, western tropical Altantic, supports Pliocene - Pleistocene deep - water linkage between hemispheres

Creator:: Harris, Sara E., Mix, Alan C., and King, Terri
Abstract:: Calcium carbonate percentages at five Ceara Rise sites were estimated at 1- to 2-k.y. intervals over the past 5 m.y., using reflectance spectroscopy and magnetic susceptibility proxies. From these estimates and detailed correlations between sites, gradients of calcite and terrigenous sediment accumulation rates in a depth transect of sites reveal...

Alkenone sea-surface temperatures and carbon burial at site 846 (Eastern Equatorial Pacific Ocean) : the last 1.3 M.Y.

Creator:: Emeis, K.-C., Doose, H., Mix, Alan C., and Schulz-Bull, D.
Abstract:: We analyzed the unsaturation ratio (U k/37 ) of long-chain ketones—a molecular sea-surface temperature (SST) indicator—concentrations of carbonate and organic carbon in sediments from Site 846 in the eastern equatorial Pacific Ocean. Based on an isotopic age model for the composite depth section of 0-46 m below seafloor and on...
