Comment on “Interpretation of Kappa and fmax filters as source effect”, by Igor A. Beresnev
Arthur D. Frankel
2019, Bulletin of the Seismological Society of America (109) 2762-2763
Beresnev (2019) advocates the use of an earthquake slip function that produces an ω-2.5 high-frequency falloff of Fourier displacement spectra in the far field, where ω denotes the angular frequency. He argues that the observed high-frequency decay of earthquake spectra can be adequately modeled by this ω-2.5 falloff, without needing...

Simple metrics predict salt-marsh sediment fluxes
Daniel J. Nowacki, Neil K. Ganju
2019, Geophysical Research Letters (46) 12250-12257
The growth (or decay) of salt marshes depends on suspended-sediment flux into and out of the marsh. Suspended-sediment concentration (SSC) is a key element of the flux, and SSC-based metrics reflect the long-term sediment-flux trajectories of a variety of salt marshes. One metric, the flood–ebb SSC differential, correlates with area-normalized...
