Studying earthquakes from lake sediment: Lacustrine paleoseismology in Alaska
USGS researchers in Alaska, including geologist and Mendenhall Fellow Drake Singleton of the Pacific Coastal and Marine Science Center, are using techniques from a discipline known as lake paleoseismology, studying cores of lake sediment to reconstruct past seismic activity.

Twenty-first-century projections of shoreline change along inlet-interrupted coastlines
Sandy coastlines adjacent to tidal inlets are highly dynamic and widespread landforms, where large changes are expected due to climatic and anthropogenic influences. To adequately assess these important changes, both oceanic (e.g., sea-level rise) and terrestrial (e.g., fluvial sediment supply) processes that govern the local sediment budget must...

H.; van der Spek, Ad New geochemical tools for investigating resource and energy functions at deep-sea cold seeps using amino-acid δ15N in chemosymbiotic mussels (Bathymodiolus childressi)
In order to reconstruct the ecosystem structure of chemosynthetic environments in the fossil record, geochemical proxies must be developed. Here, we present a suite of novel compound-specific isotope parameters for tracing chemosynthetic production with a focus on understanding nitrogen dynamics in deep-sea cold seep environments. We examined the...
Vokhshoori, Natasha; McCarthy, Matt; Close, Hilary; Demopoulos, Amanda; Prouty, Nancy G. Land-based sediment sources and transport to southwest Puerto Rico coral reefs after Hurricane Maria, May 2017 to June 2018
The effects of runoff from land on nearshore ecosystems, including coral reef communities, are influenced by both sediment supply and removal by coastal processes. Integrated studies across the land-sea interface describing sources and transport of terrestrial sediment and its nearshore fate allow reef protection initiatives to target...
