Sixth Oregon climate assessment

Creator:: Fleishman, Erica and Oregon Climate Change Research Institute
Abstract:: Consistent with its charge under Oregon House Bill 3543, the Oregon Climate Change Research Institute (OCCRI) conducts a biennial assessment of the state of climate change science, including biological, physical, and social science, as it relates to Oregon and the likely effects of climate change on Oregon. This sixth Oregon...

The effects of thermodynamic parameterizations, ice shelf geometry, and tides on modeled basal melting of Weddell Sea ice shelves

Creator:: Mueller, Rachael D.
Abstract:: Antarctic Ice Sheet mass balance and, hence, sea level change is affected by the floating extensions of outlet glaciers and ice streams that take up about 44% of the coastline (Drewry et al., 1982) and are referred to as "ice shelves". Ice sheet mass loss accelerates when these ice shelves...

Signatures in the Subsurface - Big & Small Data Approaches for the Spatio-Temporal Analysis of Geologic Properties & Uncertainty Reduction

Creator:: Rose, Kelly Kathleen
Abstract:: Despite more than two centuries of exploration, including more than six million deep wellbores with depths exceeding 40,000 feet in some parts of the world, our ability to constrain subsurface processes and properties remains limited. Characteristics of the subsurface vary and can be analyzed on a variety of spatial scales....

Anomalous porosity preservation and preferential accumulation of gas hydrate in the Andaman accretionary wedge, NGHP-01 site 17A

Creator:: Rose, Kelly K., Johnson, Joel E., Torres, Marta E., Hong, Wei-Li, Giosan, Liviu, Solomon, Evan A., Kastner, Miriam, Cawthern, Thomas, Long, Philip E., and Schaef, H. Todd
Abstract:: In addition to well established properties that control the presence or absence of the hydrate stability zone, such as pressure, temperature, and salinity, additional parameters appear to influence the concentration of gas hydrate in host sediments. The stratigraphic record at Site 17A in the Andaman Sea, eastern Indian Ocean, illustrates...

Unraveling the Diagenetic Cycling and Sequestration of Rare Earth Elements (REEs) in Marine Sediments to Understand REE Accumulation in Ancient Shales

Creator:: Yang, Jon
Abstract:: The rare earth elements (REEs) have been established as powerful tracers for a range of physiochemical processes occurring in the natural environment. They also hold significant economic importance as many technological advancements are reliant upon the REEs for their unique magnetic, luminescent, and electrochemical characteristics. In sedimentary settings, understanding the...

Past Methane Release Events and Environmental Conditions at the Upper Continental Slope of the South China Sea: Constraints by Seep Carbonates

Creator:: Han, Xiqiu, Suess, Erwin, Liebetrau, Volker, Eisenhauer, Anton, and Huang, Yongyang
Abstract:: Authigenic carbonates and chemosymbiotic biota are archives of seepage 1 history and record paleo-environmental conditions at seep sites. Based on mineral and stable isotope compositions and U/Th-isotope systematics of seep carbonates and Calyptogena sp shell fragments from three seep sites located at 22°02' ~22°09'N, 118°43'~118°52'E (water depths: 473 m to...

Mapping Wildlife-Relevant Snow Properties in Arctic-Boreal North America; Novel Modelling, Remote-Sensing, and Ground Observation Approaches

Creator:: Cosgrove, Christopher Liam
Abstract:: Arctic-boreal regions are exhibiting the symptoms of profound ecological shifts as they experience pronounced warming. Wildlife in high-latitudes are one such harbinger of change, and their populations are undergoing range-shifts, declines, and extinctions in response to their rapidly altering habitats. As the circumpolar and boreal north is snow-covered for up...

The Fully-Coupled One-Dimensional Arctic Surface Energy Budget: Climatology and Projections

Creator:: Kula, Michael R.
Abstract:: Arctic sea ice concentration and volume have declined due to greenhouse gas radiative forcing and an overall positive climate feedback. At the same time, there have been noteworthy weather and climate circulation anomalies both within the Arctic and extending through the midlatitudes and even into the tropics, leading some studies...

Investigating Influences of Natural and Anthropogenic Lead Sources on Environmental Archives at Multiple Spatial and Temporal Scales: Evidence from Oysters and Ice Cores

Creator:: Wensman, Sophia M.
Abstract:: Environmental archives provide records of natural and anthropogenic variation in the environment at different temporal and spatial scales. Lead (Pb) concentrations and isotopic ratios are useful tracers of anthropogenic emissions from industrial activities including mining, smelting, and leaded gasoline use, however, methods of measuring Pb are largely limited in low...

The Power of Three: Coral Reefs, Seagrasses and Mangroves Protect Coastal Regions and Increase Their Resilience

Creator:: Guannel, Greg, Arkema, Katie, Ruggiero, Peter, and Verutes, Gregory
Abstract:: Natural habitats have the ability to protect coastal communities against the impacts of waves and storms, yet it is unclear how different habitats complement each other to reduce those impacts. Here, we investigate the individual and combined coastal protection services supplied by live corals on reefs, seagrass meadows, and mangrove...
