2023, Ecosystem Health and Sustainability (9)
While there is consensus that blue carbon ecosystems, such as mangroves, have an important role in mitigating some aspects of global climate change, little is known about mangrove carbon cycling under elevated atmospheric CO2 concentrations (eCO2). Here, we review studies in order to identify pathways for how eCO2 might influence mangrove ecosystem carbon...
Combinatorial optimization of earthquake spatial distributions under minimum cumulative stress constraints
Eric L. Geist, Thomas E. Parsons
2023, Bulletin of the Seismological Society of America (113) 1025-1038
We determine optimal on‐fault earthquake spatial distributions using a combinatorial method that minimizes the long‐term cumulative stress resolved on the fault. An integer‐programming framework was previously developed to determine the optimal arrangement of a millennia‐scale earthquake sample that minimizes the misfit to a target slip rate determined from geodetic data....
