摘要:Abstract(#br)Antarctic Intermediate Water (AAIW) plays a central role in the Atlantic Meridional Overturning Circulation (AMOC) as the return flow of Northern Sourced Water (NSW) and is therefore of significant importance for the global climate. Past variations of the bounda...

摘要:Late Miocene tectonic changes in Mediterranean–Atlantic connectivity andclimatic changes caused Mediterranean salinity to fluctuate dramatically,including a ten-fold increase and near-freshening. Recent proxy- andmodel-based evidence suggests that at times during this Messin...

摘要:Abstract(#br)The neodymium isotope proxy has become a valuable tool for the reconstruction of past ocean water mass provenance and mixing. For its accurate application, knowledge about the origin and preservation of Nd in sedimentary archives is crucial. Recently, concerns h...

摘要:Abstract(#br)Integrated Ocean Drilling Program (IODP) Expedition 339 cored multiple sites in the Gulf of Cadiz in order to study contourite deposition resulting from Mediterranean Outflow water (MOW). One Hole, U1387C, was cored to a depth of 865.85 m below seafloor (mbsf) w...

摘要:Data from New Zealand and northern Victoria Land, Antarctica, indicate that the Cambrian Takaka Terrane intra-oceanic arc/backarc assemblage and the Bowers Terrane intra-oceanic arc/back-arc assemblage were accreted to the Gondwana margin by the Late Cambrian. Compelling similari...

摘要:Abstract(#br)Di-tert-butyl nitroxide (DTBN) was adsorbed at several alkali metal ion exchanged Y zeolites to investigate the electron pair acceptor properties of the monovalent zeolite cations Li + , Na + , K + , and Cs + . This probe molecule forms adsorption complexes with...

摘要:Abstract(#br)A high-resolution authigenic Nd isotope record has been extracted from the Fe–Mn oxyhydroxide fraction of drift sediments along the Blake Ridge in the North Atlantic. These sediments facilitate reconstruction of the timing and extent of major hydrographic change...

摘要:Abstract(#br)The properties of two-dimensional four-pulse electron spin echo envelope modulation spectra of nuclei with nuclear spin I =3/2 in disordered systems are discussed by means of calculated lithium hyperfine sublevel correlation spectra. Since a case of small coupling is...

摘要:Abstract(#br)Neodymium (Nd) isotopes extracted from authigenic sediment phases are increasingly used as a proxy for past variations in water mass provenance. To better constrain the controls of water mass provenance and nonconservative effects on the archived Nd isotope sign...

摘要:Abstract(#br)We describe the design of a pulsed electron nuclear double resonance (ENDOR) spectrometer operating at Q-band frequencies (35 GHz) for studies of transition metal ion complexes in the temperature range between 4.2 and 297 K. Specific features of the spectrometer are ...
