Holocene and latest Pleistocene paleoceanography of the northeast Pacific and its relationship to climate change in the Pacific Northwest

Creator:

Sabin, Ann Louise

Abstract:

Northeast Pacific Ocean sediments were analyzed to determine the past relationship between northeast Pacific sea surface conditions and the climate on the adjacent continent, the Pacific Northwest of North America. Studies of modern ocean-atmosphere interactions demonstrate the significant effect sea surface conditions and atmospheric circulation in the Northeast Pacific Ocean...

Determination of unsaturation-, growth phase-, and growth rate-dependent hydrogen isotopic fractionation in C₃₇ alkenones produced by Emiliania huxleyi

Creator:

Wolhowe, Matthew D.

Abstract:

Recent works have investigated use of the hydrogen isotopic composition of C₃₇ alkenones (δD[subscript K37s]), lipid biomarkers of certain haptophyte microalgae, as an independent paleosalinity proxy. I discuss herein the factors impeding such an application and identify the potential alternative use of δD[subscript K37s] measurements as a proxy for non-thermal,...

Glacial to holocene watermass and continental weathering reconstructions from the Southeast Pacific

Creator:

Muratli, Jesse M.

Abstract:

Sediments of the central Chile margin record changes in ocean circulation and continental erosion associated with large–scale climate change. Here Antarctic– influenced Southern Ocean currents flow equatorward, forming a link between the high– and low–latitude oceans. Part of this link, Antarctic Intermediate Water, is an important conduit that ventilates South...

Deconvolving the sedimentary phases of barium using flow-through time-resolved analysis

Creator:

Hsieh, Chih-Ting

Abstract:

The distribution of barite (BaSO₄) in marine sediments has long been studied as a proxy for paleoproductivity. While pure barite is known to be a stable mineral in oxic sediments, it is also known that variations in the Sr/Ba ratio influence its solubility and liability during early diagenesis. To extract...

Submarine plateau volcanism and Cretaceous Ocean Anoxic Event 1a : geochemical evidence from Aptian sedimentary sections

Creator:

Walczak, Paul S.

Abstract:

Marine sediments exceptionally rich in organic carbon, known as black shales, occur globally but intermittently in well correlated Cretaceous successions. The presence of black shales indicates that sporadic, ocean-wide interruption of normal respiration of marine organic matter during oxygen-deficient conditions has occurred. Submarine volcanism on a massive scale, related to...

Methane sources, fluid flow, and diagenesis along the northern Cascadia Margin; using authigenic carbonates and pore waters to link modern fluid flow to the past

Creator:

Joseph, Craig E.

Abstract:

Methane derived authigenic carbonate (MDAC) precipitation occurs within marine sediments as a byproduct of the microbial anaerobic oxidation of methane (AOM). While these carbonates form in chemical and isotopic equilibrium with the fluids from which they precipitate, burial diagenesis and recrystallization can overprint these signals. Plane polarized light (PPL) and...

Hydrothermal links between ocean plateau formation and global anoxia at the Cenomanian-Turonian boundary

Creator:

Snow, Laura J.

Abstract:

The Cretaceous was a period of extreme climatic conditions accompanied by major perturbations in ocean-atmosphere biogeochemical cycles. One of the most intriguing features is the sporadic interruption of normal marine pelagic sediment deposition by organic rich sediments deposited during oxygen-deficient conditions (ocean anoxic events OAEs). A current model for the...

Foraminiferal assemblages preserved in surface sediments correspond to multiple environmental and preservation variables

Creator:

Ross, Ann E. Morey

Abstract:

Here we investigate the relationships between modern foraminiferal assemblages from Atlantic and Pacific surface sediment samples and multiple environmental properties including water column and preservation variables using Canonical Correspondence Analysis (CCA). CCA finds two fauna] dimensions that are highly correlated to the environmental variables included in the analysis, and then...
