Regional and global forcing of glacier retreat during the last deglaciation

Creator:: Shakun, Jeremy D., Clark, Peter U., He, Feng, Lifton, Nathaniel A., Liu, Zhengyu, and Otto-Bliesner, Bette L.
Abstract:: The ongoing retreat of glaciers globally is one of the clearest manifestations of recent global warming associated with rising greenhouse gas concentrations. By comparison, the importance of greenhouse gases in driving glacier retreat during the most recent deglaciation, the last major interval of global warming, is unclear due to uncertainties...

Dynamic range and sensitivity requirements of satellite ocean color sensors: learning from the past

Creator:: Hu, Chuanmin, Feng, Lian, Lee, Zhongping, Davis, Curtiss O., Mannino, Antonio, McClain, Charles R., and Franz, Bryan A.
Abstract:: Sensor design and mission planning for satellite ocean color measurements requires careful consideration of the signal dynamic range and sensitivity (specifically here signal-to-noise ratio or SNR) so that small changes of ocean properties (e.g., surface chlorophyll-a concentrations or Chl) can be quantified while most measurements are not saturated. Past and...

Global climate evolution during the last deglaciation

Creator:: Clark, Peter U., Shakun, Jeremy D., Baker, Paul A., Bartlein, Patrick J., Brewer, Simon, Brook, Edward J., Carlson, Anders E., Cheng, Hai, Kaufman, Darrell S., Liu, Zhengyu, Marchitto, Thomas M., Mix, Alan C., Morrill, Carrie, Otto-Bliesner, Bette L., Pahnke, Katharina, Russell, James M., Whitlock, Cathy, Adkins, Jess F., Blois, Jessica L., Clark, Jorie, Colman, Steven M., Curry, William B., Flower, Ben P., He, Feng, Johnson, Thomas C., Lynch-Stieglitz, Jean, Markgraf, Vera, McManus, Jerry, Mitrovica, Jerry X., Moreno, Patricio I., and Williams, John W.
Abstract:: Deciphering the evolution of global climate from the end of the Last Glacial Maximum approximately 19 ka to the early Holocene 11 ka presents an outstanding opportunity for understanding the transient response of Earth's climate system to external and internal forcings. During this interval of global warming, the decay of...

Spatial and Temporal Dynamics of Broad-scale Predictive Models : Influences of Scale

Creator:: Hooper, Samuel
Abstract:: Developing accurate predictive distribution models requires adequately representing relevant spatial and temporal scales, as these scales are ultimately reflective of the relationships between distributions and influential environmental conditions. In this research, we considered both spatial and temporal scale and the influence each has on predicting broad-scale distributions of two disparate...

Social reconstruction in dam-induced displacement: A case study of four resettlement projects on the Lancang River, China

Creator:: Tang, Yingqi
Abstract:: Involuntary movement, also known as forced displacement, has affected millions of people worldwide. At the end of 20th century, approximately 80 million people had been displaced due to hydropower projects, including approximately 22.5 million people in China. Dam-induced migration not only causes material loss, such as loss of homes and...

Invisibility: Environmental Migration Governance in a Changing Climate

Creator:: Abel, Kali M.
Abstract:: Climate change has the potential to accelerate many forms of human migration and mobility, yet almost all of the key migration outcomes of interest are determined predominantly by governance, or the norms, laws, and institutions involved in the coordination of human society. These outcomes include the decision whether or not...

Buffering Estuarine Sediments Against Acidification

Creator:: Myers, Tristen J.
Abstract:: Globally rising anthropogenic CO₂ emissions have resulted in the increased prevalence of ocean acidification (OA) which has the potential to impact shell-forming organisms. On geologic timescales, the largest contributor to atmospheric CO₂ was volcanoes, counterbalanced by weathering and erosion, but due to increased anthropogenic emissions, these processes alone can no...

Late Cenozoic Climate, Ice-sheet and Earth-surface Evolution Derived from Terrestrial and Marine Sedimentary Archives

Creator:: Bill, Nicholas S.
Abstract:: The goals of this dissertation are centered on understanding changes in Earth surface and climate systems through the use of geologic proxies as records of past changes in these systems. Specifically, this dissertation (1) establishes a new chronology for retreat of the Ross Sea sector of the West Antarctic Ice...

Illuminating Patterns in Dark Microbial Matter: Diversity and Distribution of Fungi and Actinobacteria in Deep-sea Methane Seep Sediments

Creator:: Ardor Bellucci, Lila
Abstract:: Fungi and Actinobacteria are essential actors in global biogeochemical cycles of carbon and nutrients, and have both been recently appreciated for their roles in marine ecosystems. However, the diversity and distribution of these ubiquitous, but low-abundance microbes in deep-sea habitats remains poorly understood, particularly in chemosynthetic habitats such as methane...

Satellite observations of the inﬂuence of mesoscale ocean eddies on near-surface temperature, phytoplankton and surface stress

Creator:: Gaube, Peter
Abstract:: The influence of mesoscale ocean eddies on near-surface ocean temperature, surface stress and phytoplankton communities is investigated by collocating numerous satellite measurements along with vertical profiles of oceanic temperature and salinity to the interiors of eddies identified and tracked in altimetric sea surface height maps. The surface currents associated with...
