A 37,000-year record of paleomagnetic and environmental magnetic variability from Burial Lake, Arctic Alaska

Creator:: Dorfman, Jason Michael
Abstract:: Burial Lake sediments from the Noatak Basin in the northwest Brooks Range of Arctic Alaska (68.43°N, 159.17°W, 21.5 m water depth) provide the oldest continuous lacustrine record of paleo-environmental change and paleomagnetic secular variation (PSV) in eastern Beringia. A precise radiocarbon chronology, determined through accelerator mass spectrometry (AMS) allows us...

Deciphering Quaternary Geomagnetic, Glacial, and Depositional Histories Using Paleomagnetism in Tandem with Other Chronostratigraphic and Sedimentological Approaches

Creator:: Reilly, Brendan T.
Abstract:: Stratigraphy and chronology are essential to sedimentological study of Earth system histories. And, stratigraphy and chronology are often challenging and interesting problems themselves. The Quaternary (2.588 Ma - present) experienced paleoenvironmental and paleo-geomagnetic variability well outside the range of the recent instrumental record, providing the opportunity to place recent observations...

Deep-sea sediment paleomagnetism : a case study from the North Atlantic

Creator:: Strano, Sarah Elianna
Abstract:: Sedimentary records from the North Atlantic, instrumental in the development of modern paleo-geomagnetic concepts, show a highly variable field even during times of constant polarity. Yet, our understanding of how the magnetization is acquired in the sediments is poorly understood. Primary magnetizations preserved in deep-sea sediments are known to be...

A Paleomagnetic and Environmental Magnetic Record from the Eastern South Pacific Sector of the Southern Ocean (0-1.7 Ma): IODP Site U1543

Creator:: Monito, Lindsey
Abstract:: This research presents a u-channel based study of the natural remanent magnetization (NRM), the laboratory magnetization, Anhysteretic Remanent Magnetization (ARM), and magnetic susceptibility (k), from the upper 100 m of International Ocean Discovery Program (IODP) Expedition 383 Site U1543 in the eastern South Pacific sector of the Southern Ocean. Alternating...

Exploring the Magnetic Properties of Specific Grain-Sizes to Understand Marine Depositional Systems: A Case Study from the Eirik Ridge South of Greenland over the Last Glacial Cycle

Creator:: Freiberg, Benjamin T.
Abstract:: Disentangling sediment source from sediment transport is a fundamental marine geologic challenge critical to the interpretation of any sedimentary record. The Eirik Ridge, a sediment drift south of Greenland, receives terrigenous sediment primarily from subglacial erosion of south Greenland’s Precambrian bedrock and Paleogene volcanics that outcrop in east Greenland and...

Submarine earthquakes, volcanic eruptions and ambient noise in the Northeast Pacific

Creator:: Haxel, Joseph H.
Abstract:: Passive hydrophone technologies and a variety of acoustic methods are applied in the deep-ocean and shallow water coastal environments of the northeast Pacific. A catalog derived from U.S. Navy regional hydrophone array recordings of acoustic T- phases from seafloor earthquakes is examined, describing space/time patterns through empirical orthogonal function analysis...

Heat flow results from plate boundary observatory boreholes in California

Creator:: McDonald, Kyle Joseph
Abstract:: An integral component to understanding lithospheric rheology, fault mechanics, and geodynamic processes is knowledge of the subsurface thermal regime. This study presents thermal data from 26 new borehole sites drilled during the installation of borehole strain meters as part of the Plate Boundary Observatory (PBO). These data extends existing coverage...

Resurgent Uplift of Samosir Island in Toba Caldera, Indonesia : Insights from Lake Sediment Paleomagnetism and C-14 Age Determination

Creator:: Solada, Katharine
Abstract:: Around 74 ka, a supervolcano, Toba Caldera in Sumatra, Indonesia erupted, producing the Youngest Toba Tuff and its associated caldera. After this catastrophic eruption, a lake filled the caldera, sedimentation within the lake occurred, and the process known as resurgence began. Today, the resurgent dome, Samosir Island, is uplifted 700...

An Exploration of Climate Change, Conservation, and Cooperation, in Three Essays

Creator:: Johnson, Steven Mana'oakamai
Abstract:: The defining feature of our planet are the oceans, which make up 70% of the Earth’s surface. The importance of the ocean cannot be understated: 50% of oxygen originates from phytoplankton; heat is absorbed and redistributed by ocean currents; and hundreds of millions of people rely on the ocean for...

New Foraminifera-Based Proxies to Trace Changes to the Organic and Inorganic Carbon System Since the Last Glacial Maximum

Creator:: Fritz-Endres, Theresa
Abstract:: The production of carbon and export to deep ocean sediments is linked to carbon partitioning between the ocean and atmosphere and is a key driver of climate change over the glacial-interglacial transition. Yet conflicting reconstructions create barriers to understanding changes to the carbon system over this important climate transition. Production...
