Seismic gravity-gradient noise in interferometric gravitational-wave detectors [PDF]

, 1998
When ambient seismic waves pass near and under an interferometric gravitational-wave detector, they induce density perturbations in the Earth, which in turn produce fluctuating gravitational forces on the interferometer’s test masses.

Blip glitches in Advanced LIGO data [PDF]

, 2019
Blip glitches are short noise transients present in data from ground-based gravitational-wave observatories. These glitches resemble the gravitational-wave signature of massive binary black hole mergers.

Understanding Contaminant Migration Within a Dynamic River Corridor Through Field Experiments and Reactive Transport Modeling

Frontiers in Water, 2020
The behavior of a persistent uranium plume within an extended river corridor at the DOE Hanford site is dominantly controlled by river stage fluctuations in the adjacent Columbia River.

A multi-scale temperature-based strategy to map hydrologic exchange flows in highly dynamic systems

Frontiers in Earth Science, 2022
Mapping and quantifying hydrologic exchange flows (HEFs) is critical to environmental monitoring and remediation at contaminated sites; however, these objectives are challenging in highly dynamic systems, e.g., along dam-regulated rivers, where HEFs vary

Gravitation Physics at BGPL [PDF]

, 2006
We report progress on a program of gravitational physics experiments using cryogenic torsion pendula undergoing large-amplitude torsion oscillation. This program includes tests of the gravitational inverse square law and of the weak equivalence principle.

Hanford Site Environmental Report 1993 [PDF]

, 1994
The Hanford Site Environmental Report is prepared annually to summarize environmental data and information, describe environmental management performance, and demonstrate the status of compliance with environmental regulations. The report also highlights major environmental programs and efforts.

Fe-phyllosilicate redox cycling organisms from a redox transition zone in Hanford 300 Area sediments

Frontiers in Microbiology, 2013
Microorganisms capable of reducing or oxidizing structural iron (Fe) in Fe-bearing phyllosilicate minerals were enriched and isolated from a subsurface redox transition zone at the Hanford 300 Area site in eastern Washington, USA.

Network sensitivity to geographical configuration [PDF]

, 2001
Gravitational wave astronomy will require the coordinated analysis of data from the global network of gravitational wave observatories. Questions of how to optimally configure the global network arise in this context.
