Trends in nitrate levels in Iowa's community water systems (2000–2022): Characteristics of systems vulnerable to maximum contaminant level exceedances and future regulatory scenarios

open access: yesJournal of Environmental Quality, Volume 55, Issue 3, May/June 2026.
Abstract This study examines trends in nitrate contamination in Iowa's community water systems (CWS) from 2000 to 2022, focusing on the characteristics of CWS that are most vulnerable to elevated nitrate levels and those likely to be impacted by a lower maximum contaminant level (MCL).

New Tool for Zooarchaeological Analysis: ArcGIS Skeletal Templates for Some Common Mammalian Species

open access: yesInternet Archaeology, 2010
Zooarchaeological results are often best presented in the form of anatomical diagrams, but these can be very time-consuming to produce. This article presents ArcGIS format skeletal templates for six common mammalian species, allowing faunal analysts to ...

Rotary wing brown-out symbology: the DVEST test [PDF]

open access: yes, 2012
Military helicopter operations encounter degraded visual environments (DVE) on a regular basis. A DVE exists when conditions of low visibility, including those caused by rotor downwash in sand/dust ("brown-out"), snow ("whiteout"/ snowball) or water ...

Timing of Metamorphism and Deformation in the Neoarchean Quetico Metasedimentary Belt, Superior Craton, Constrained by Garnet Trace‐Element Mapping and Lu–Hf Geochronology

open access: yesJournal of Metamorphic Geology, Volume 44, Issue 4, Page 265-286, May 2026.
ABSTRACT The Quetico subprovince of the Superior Province is among the largest metasedimentary belts globally and provides evidence of tectonic processes at play during the final stages of Archean cratonization. Although previous studies have shown that deformation and metamorphism of the 2.7‐Ga turbiditic protolith resulted in regional subvertical ...
