On the fidelity of oxygen isotope-based sea level reconstructions: A case study of Marine Isotope Stage 3 On the fidelity of oxygen isotope-based sea level reconstructions: A case study of Marine Isotope Stage 3
Although foraminiferal oxygen isotope records (δ18OF) have long been used to develop time-continuous estimates of past global ice volume, growing evidence indicates that the ice volume and temperature contributions to δ18OF diverge considerably over the last glacial cycle. Across Marine Isotope Stage 3 (MIS 3; 57 to 29 ka), estimates of peak global sea level based on δ18OF are ∼30 m...
Probabilistic forecasting of coastal wetland elevation and soil carbon response to sea-level rise Probabilistic forecasting of coastal wetland elevation and soil carbon response to sea-level rise
Tidal wetlands build soil as a dynamic response to inundation, resulting in carbon sequestration and resilience to sea-level rise. Process models can be used to make site-specific forecasts, anticipate future changes, and plan management responses. But to be actionable, forecasts from these models need to be accompanied by descriptions of their confidence. In this study, we demonstrate...
Microfocus X-ray computed tomography to evaluate ostracode shell density and other metrics for monitoring ocean acidification in the Arctic Ocean Microfocus X-ray computed tomography to evaluate ostracode shell density and other metrics for monitoring ocean acidification in the Arctic Ocean
Ocean acidification (OA) poses a significant threat to the ability of marine calcifying organisms—such as mollusks, corals, crustaceans, and plankton—to form and maintain their calcium carbonate-based shells. While some species show greater sensitivity to OA than others, the impacts on benthic marine calcifiers remain inadequately understood. This study investigates the shell density...
Science
Wolverine Glacier
Wolverine Glacier is located in Alaska’s Kenai Mountains, along the western flank of Prince William Sound. Glacier observations began in 1966 and continue through present as the western most USGS Benchmark Glacier.
Lemon Creek Glacier
Lemon Creek Glacier is located in southeast Alaska, at the southernmost tip of the Juneau Icefield. Glacier observations began at this site in 1953 and continue through present, serving as a central site between glaciers in the contiguous USA and those in mainland Alaska.
Gulkana Glacier
Gulkana Glacier is located in the high-latitude continental climate regime of Alaska’s Delta Mountains. Glacier observations began at this site in 1966 and continue through present as the northern most USGS Benchmark Glacier.
