About

DelWayne Bohnenstiehl is a Professor in the Department of Marine, Earth and Atmospheric Sciences at NC State University. His research utilizes geophysical tools to address a wide range of problems, including underwater sound and ocean noise, soundscape ecology, seafloor and lake-bed mapping, earthquake seismology and seismotectonics, paleoseismology, landscape and terrain processes, submarine volcanism, archaeological geophysics, and environmental geophysics. He is also a Faculty Fellow at the Center for Geospatial Analytics and is involved with the Unmanned Surface Vehicle Facility. Dr. Bohnenstiehl holds a PhD in Marine Geology & Geophysics from Columbia University, an MS in Geology from Vanderbilt University, and a BS in Geology from Eastern Illinois University. His work focuses on applying geophysical methods to understand various geological and environmental phenomena.

• The Mw 5.1, 9 August 2020, Sparta Earthquake, North Carolina: The First Documented Seismic Surface Rupture in the Eastern United States

  GSA Today · 2022 · 38 citations

  At 8:07 a.m. EDT on 9 Aug. 2020 a M w 5.1 earthquake located ~3 km south of Sparta, North Carolina, USA, shook much of the eastern United States, producing the first documented surface rupture due to faulting east of the New Madrid seismic zone. The co-seismic surface rupture was identified along a 2-km-long traceable zone of predominantly reverse displacement, with folding and flexure generating a scarp averaging 8-10-cm-high with a maximum observed height of ~25 cm. Widespread deformation sout…

• Passive acoustic monitoring complements traditional methods for assessing marine habitat enhancement outcomes

  Ecosphere · 2021-11-01 · 19 citations

  articleOpen access

  Abstract Habitat enhancement, often accomplished through the introduction of artificial structures, is a common strategy used by marine resource managers to provide habitat subsidies, protect sensitive habitat, and create new fishing opportunities. Traditional monitoring methods for assessing habitat enhancement outcomes face numerous limitations, including dependence on environmental conditions and trade‐offs between sampling frequency and duration. Passive acoustic monitoring (PAM) is not subj…

• Quantification of Eruption Dynamics on the North Rift at Axial Seamount, Juan de Fuca Ridge

  Geochemistry Geophysics Geosystems · 2020 · 18 citations

  Abstract Quantifying eruption dynamics in submarine environments is challenging. During the 2015 eruption of Axial Seamount, the formation of hummocky mounds along the north rift was accompanied by tens of thousands of impulsive acoustic signals generated by the interaction of lava and seawater. A catalog of these sounds was integrated with detailed seafloor mapping to better understand eruptive processes in time and space. Mounds grew over a period of 28 days with average extrusion rates of 22…

• Revised Magmatic Source Models for the 2015 Eruption at Axial Seamount Including Estimates of Fault‐Induced Deformation

  Journal of Geophysical Research Solid Earth · 2020 · 14 citations

  Senior authorCorresponding

  Abstract Axial Seamount is an active submarine volcano located at the intersection of the Cobb hot spot and the Juan de Fuca Ridge (45°57′N, 130°01′W). Bottom pressure recorders captured co‐eruption subsidence of 2.4–3.2 m in 1998, 2011, and 2015, and campaign‐style pressure surveys every 1–2 years have provided a long‐term time series of inter‐eruption re‐inflation. The 2015 eruption occurred shortly after the Ocean Observatories Initiative (OOI) Cabled Array came online providing real‐time sei…
