The structural formula was calculated on the basis of eight oxygenes.

The structural formula was calculated on the basis of six oxygenes.

We determined the sedimentary concentrations of phosphorus (P), barium (Ba), manganese (Mn), titanium (Ti), aluminum (Al), and uranium (U) for sediment samples from the southeast Pacific Nazca Ridge, Ocean Drilling Program Site 1237. This unique record extends to 31 Ma over 360 meters composite depth (mcd), recording depositional history as the site progressed eastward over its paleohistory. We sampled with a temporal resolution of ~0.2 m.y. throughout the sequence, equivalent to an average spacing of...

The isotopic composition of nitrogen in pore water ammonium and in sedimentary organic matter (Norg) was measured at Sites 1234 and 1235 in order to evaluate the impact of long-term (>100 k.y.) diagenesis on d15N of preserved organic matter. At both sites, the average d15N of pore water ammonium and Norg are within 0.2 per mil to 0.4 per mil. The small difference is less than the analytical uncertainty, indicating that no significant isotopic fractionation...

The exchange of waters between the Pacific and the Southern Oceans occurs along the eastern boundary of the South Pacific. Because water masses of the Antarctic provide a connection among the world's ocean basins, these water masses maintain the ability to influence changes in ocean circulation and climate (Lynch-Stieglitz et al., 1996, doi:10.1029/95PA03772). One of the primary goals of Ocean Drilling Program (ODP) Leg 202 was to exploit the sediments underlying the southeast Pacific continental...

We determined oxygen isotopic compositions of interstitial water (IW) recovered during Ocean Drilling Program Leg 207. Five sites were cored (3200- to 1900-m water depth) on Demerara Rise off Suriname, South America, recovering a Cenomanian-Paleogene sedimentary sequence consisting of black shales and chalks. A total of 115 IW oxygen isotopic analyses are presented.

This data set reports the thickness of peat for the S1 Bog measured directly with manual push probes on September 21 and 22, 2009, and measured by ground penetrating radar (GPR) across transects from January 26 to February 2, 2010 and June 2 to June 9, 2010. Also included are interpolated values of peat depth from both probe and GPR data for the S1 Bog at 1 meter square horizontal resolution.The key objectives of these...
