Seismic monitoring to assess performance of structures In near‐real time: Recent progress Seismic monitoring to assess performance of structures In near‐real time: Recent progress
Earlier papers have described how observed data from classical accelerometers deployed in structures or from differential GPS with high sampling ratios deployed at roofs of tall buildings can be configured to establish seismic health monitoring of structures. In these configurations, drift ratios1 are the main parametric indicator of damage condition of a structure or component of a...

Site characterization of Italian strong motion recording stations Site characterization of Italian strong motion recording stations
A dataset of site conditions at 101 Italian ground motion stations with recorded motions has been compiled that includes geologic characteristics and seismic velocities. Geologic characterization is derived principally from local geologic investigations by ENEL that include detailed mapping and cross sections. For sites lacking such detailed geologic characterization, the geology maps of...

Hemlock ecosystem monitoring in southern West Virginia Hemlock ecosystem monitoring in southern West Virginia
We initiated a long-term hemlock ecosystem monitoring study in 1998 on the New River Gorge National River (NERI) and Gauley River National Recreation Area (GARI), in Nicholas, Fayette, and Raleigh counties, West Virginia, to quantify ecosystem response to invasion by the hemlock woolly adelgid (HWA). Hemlock vigor and degree of adelgid infestation were quantified in 1998-2007, vegetation...

Gathering, organizing, and accessing data for use in bird conservation across the Americas Gathering, organizing, and accessing data for use in bird conservation across the Americas
The U.S. North American Bird Conservation Initiative (NABCI) Monitoring Subcommittee (2007) identified the need for a comprehensive plan for integrating and managing bird population monitoring data, and to adapt this as an integral component for improving monitoring activities across North America. While the Subcommittee provided a basic framework to begin development of this data...

Lead isotopes and trace metals in dust at Yucca Mountain Lead isotopes and trace metals in dust at Yucca Mountain
Lead (Pb)-isotope compositions and trace-metal concentrations were determined for samples of dust collected from underground and surface locations at and near the proposed radioactive waste repository at Yucca Mountain, Nevada. Rare earth element concentrations in the dust samples from the underground tunnels are similar to those in wholerock samples of the repository host rocks (Miocene...

Subsurface fate and transport of sulfamethoxazole, 4-nonylphenol, and 17β-estradiol Subsurface fate and transport of sulfamethoxazole, 4-nonylphenol, and 17β-estradiol
Subsurface fate and transport of the antibiotic sulfamethoxazole (SX), the non-ionic surfactant degradation product 4-nonylphenol (NP), and the sex hormone 17β-estradiol (E2) were evaluated in a plume of contaminated groundwater at Cape Cod, Massachusetts, USA. The plume is the result of 60 years of wastewater treatment plant effluent disposal into rapid infiltration beds. Natural...

Use of a groundwater flow model to assess the location, extent, and hydrologic properties of faults in the Rialto-Colton Basin, California Use of a groundwater flow model to assess the location, extent, and hydrologic properties of faults in the Rialto-Colton Basin, California
Faults within a groundwater basin can greatly influence the direction of groundwater flow and contaminant migration. Existing steady-state and transient groundwater flow models were used to assess the location, extent, and hydrologic properties of two alternative fault configurations within the Rialto-Colton basin. Adjustments were made to the hydrologic properties of the faults and the...

A bird community on the edge: habitat use of forest songbirds In eastern Oklahoma A bird community on the edge: habitat use of forest songbirds In eastern Oklahoma
Several species of forest songbirds reach a western limit of their respective distributions in eastern Oklahoma. The relative infl uence of various habitat variables on patterns of occurrence in this region may differ from those same infl uences in the core of species’ ranges. We examined the infl uence of 16 habitat variables on the occurrence and density of a suite of forest songbirds...
