Creator:: Abbott, April N., Haley, Brian A., and McManus, James
Abstract:: The ability to reconstruct past ocean currents is essential for determining ocean circulation’s role in global heat transport and climate change. Our understanding of the relationship between circulation and climate in the past allows us to predict the impact of future climate-driven circulation changes. One proposed tracer of past ocean...

Creator:: Abbott, April N., Haley, Brian A., McManus, James, and Reimers, Clare E.
Abstract:: We determined pore fluid rare earth element (REE) concentrations in near-surface sediments retrieved from the continental margin off Oregon and California (USA). These sites represent shelf-to-slope settings, which lie above, within, and below the oxygen minimum zone of the Northeast Pacific. The sediments are characterized by varying degrees of net...

Creator:: Abbott, April N., Haley, Brian A., and McManus, James
Abstract:: Because ocean circulation impacts global heat transport, understanding the relationship between deep ocean circulation and climate is important for predicting the ocean's role in climate change. A common approach to reconstruct ocean circulation patterns employs the neodymium isotope compositions of authigenic phases recovered from marine sediments. In this approach, mild...

Creator:: Torres, Marta E., Mix, Alan C., Kinports, K., Haley, Brian A., Klinkhammer, Gary P., McManus, James, and de Angelis, M. A.
Abstract:: The isotopic composition of the dissolved inorganic carbon (DIC) collected at sites of active methane discharge on Hydrate Ridge, Oregon, reveals anaerobic methane oxidation mediated by bacteria, with δ13CDIC reaching values as low as –48‰ in the upper 4 cm of the sediment. In spite of the high sulfide levels...

Creator:: Carlson, Anders E., Clark, Peter U., Haley, Brian A., Klinkhammer, Gary P., Simmons, Kathleen, Brook, Edward J., and Meissner, Katrin J.
Abstract:: The Younger Dryas cold interval represents a time when much of the Northern Hemisphere cooled from ≈12.9 to 11.5 kiloyears B.P. The cause of this event, which has long been viewed as the canonical example of abrupt climate change, was initially attributed to the routing of freshwater to the St....

Creator:: Stichel, Torben, Frank, Martin, Rickli, Jorg, Hathorne, Ed C., Haley, Brian A., Jeandel, Catherine, and Pradoux, Catherine
Abstract:: Radiogenic isotopes of hafnium (Hf) and neodymium (Nd) are powerful tracers for water mass transport and trace metal cycling in the present and past oceans. However, due to the scarcity of available data the processes governing their distribution are not well understood. Here we present the first combined dissolved Hf...
