Are equilibrium shoreline models just convolutions? Are equilibrium shoreline models just convolutions?
Yes. Equilibrium shoreline models, which simulate wave-driven cross-shore erosion and accretion, are mathematically equivalent to a discrete convolution (i.e., a weighted, moving average) of a time series of wave-forcing conditions with a parameterized memory-decay kernel function. The direct equivalence between equilibrium shoreline models and convolutions reveals key theoretical...
Waterline responses to climate forcing along the North American West Coast Waterline responses to climate forcing along the North American West Coast
Understanding waterline variability at seasonal to interannual timescales is crucial for predicting coastal responses to climate forcing. However, relationships between large-scale climate variability and coastal morphodynamics remain underexplored beyond intensively monitored sites. This study leverages a newly developed 25-year (1997–2022) satellite-derived waterline dataset along the...
Marsh sediment in translation: A review of sediment transport across a natural tidal salt marsh in northern San Francisco Bay Marsh sediment in translation: A review of sediment transport across a natural tidal salt marsh in northern San Francisco Bay
Deposition of inorganic sediment is essential for the sustainability of tidal salt marshes. Understanding variability in sediment sources and the processes of sediment delivery to salt marshes are high priorities for decision-makers responsible for managing sediment and conserving and restoring marshes. Research on sediment transport to marshes is published in technical journals, but...

Seafloor Benthic Mapping and Characterization: Enhancing our Understanding of Aleutian Islands’ Hazards, Potential Seabed Minerals and Deep Corals
A USGS-led expedition in the Aleutian Arc off Alaska will provide critical information on energy resources, underwater earthquakes and other hazards, seafloor habitats, and biological resources, including key fisheries, as well as potential seabed minerals.
