Advancements in the Monitoring of Forests and Quantification of Live Aboveground Biomass Using Moderate Resolution Spaceborne Multispectral Imagery and Synthetic Aperture Radar Data

Creator:: Kilbride, John B.
Abstract:: The objective of this dissertation is to enhance the monitoring of forest ecosystems through the utilization of remotely sensed data to address the exigencies posed by the Anthropocene. On a global scale, rising temperatures and fluctuating precipitation patterns have strained forests and produced shifts in natural disturbance regimes. Additionally, the...

Revisiting Lōʻihi: Geochemistry of Kamaʻehuakanaloa Lavas Reveals Complexities in the Pre-Shield to Shield Transition and Hawaiian Mantle Plume Source

Creator:: Truong, Thi B.
Abstract:: Studies of Hawaiian volcanoes contribute valuable insights about Earth processes and mantle evolution, and are fundamental for understanding the construction of the largest volcanoes on terrestrial planets. The pre-shield stage exists in every Hawaiian volcano, but is usually blanketed by high volume tholeiitic lava flows during the main shield stage....

Metagenomic and metatranscriptomic inventories of the lower Amazon River, May 2011

Creator:: Satinsky, Brandon M., Fortunato, Caroline S., Doherty, Mary, Smith, Christa B., Sharma, Shalabh, Ward, Nicholas D., Krusche, Alex V., Yager, Patricia L., Richey, Jeffrey E., Moran, Mary Ann, and Crump, Byron C.
Abstract:: Background: The Amazon River runs nearly 6500 km across the South American continent before emptying into the western tropical North Atlantic Ocean. In terms of both volume and watershed area, it is the world’s largest riverine system, affecting elemental cycling on a global scale. Results: A quantitative inventory of genes...

Citizen Science Research : A Focus on Historical Whaling Data and a Current Marine Mammal Citizen Science Project, Whale mAPP

Creator:: Hann, Courtney
Abstract:: Citizen science work has built the foundation of much of our knowledge on regional-scale large cetacean spatial patterns through historical whaling data. Historical whaling data on sperm whales was used as an example to show the type of ecological questions large-scale, long-term citizen science datasets can address. Results from the...

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...

Summary : Pacific Northwest Drought and Human Health Workshop

Creator:: Oregon Climate Change Research Institute, National Integrated Drought Information System, and University of Nebraska Medical Center
Abstract:: Drought can have substantial negative effects on human health, creating challenges for public health departments, emergency managers, and healthcare providers. For example, drought can lead to decreased water quantity and quality, increased incidence of illness or disease, increased mortality rates, and adverse mental health outcomes, especially as livelihoods are affected....

Low-tide rainfall effects on metal content of suspended sediment in the Sacramento-San Joaquin Delta

Creator:: Moskalski, Susanne M., Torres, Raymond, Bizimis, Michael, Goni, Miguel, Bergamaschi, Brian, and Fleck, Jacob
Abstract:: Rain falling at or near low tide is capable of eroding and transporting cohesive sediment from intertidal areas. Given that metals adsorb strongly to silt- and clay-sized particles, it is conceivable that low-tide rainfall may also liberate previously-deposited metals from storage in intertidal sediment. To investigate the potential for rainfall...

Of Mysid and Menidia: Sublethal Effects of Micro and Nanoplastics on Estuarine Indicator Species

Creator:: Dickens, John
Abstract:: Microplastics are widely distributed in aquatic environments. The term ‘microplastics’ encompasses a wide array of particles with unique polymer constituents, morphologies, and sources, such as automobile tire tread. Tire wear particles (TWP) can end up in waterways near densely populated municipalities, where they can interact with aquatic biota. Studying the...

Southern Ocean control of glacial AMOC stability and Dansgaard-Oeschger interstadial duration

Creator:: Buizert, Christo and Schmittner, Andreas
Abstract:: Glacial periods exhibit abrupt Dansgaard-Oeschger (DO) climatic oscillations that are thought to be linked to instabilities in the Atlantic meridional overturning circulation (AMOC). Great uncertainty remains regarding the dynamics of the DO cycle, as well as controls on the timing and duration of individual events. Using ice core data we...

Timescales and tectonics of oceanic plateaus : long-term evolution of Ontong Java Nui and Rio Grande Rise

Creator:: Davidson, Peter C.
Abstract:: Oceanic plateaus are regions of overthickened oceanic crust and are often thought to form from the interaction of mantle plumes with oceanic lithosphere. These regions can cover vast areas of the ocean basins and represent a highly elevated magmatic flux relative to normal mid-ocean ridge spreading. Oceanic plateaus are considered...
