Ecosystems Land Change Science Program

The Land Change Science Program in the USGS Ecosystems Mission Area strives to advance the understanding of the physical, chemical, and biological components of the Earth system, the causes and consequences of ecosystem and land use change, and the vulnerability and resilience of the Earth system to such changes.

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...

Glaciers and Landscape Change

Mountain glaciers are dynamic reservoirs of frozen water, deeply interconnected with their surrounding ecosystems. Glacier change in North America has major societal impacts, including to water resources, natural hazard risk, tourism disruption, fisheries, and global sea level change. Understanding and quantifying precise connections between changing glaciers, the surrounding landscape and climate...

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.
