Brent M. Hall compares water-quality observations from streams in the Greater Mooses Tooth unit of Alaska’s National Petroleum Reserve. The study brings measurements collected in 2023 together with earlier sampling from 2010 to examine conditions in a landscape that includes oil-production infrastructure.
The report describes the sampling locations and methods, compares chemical measurements and considers the limits of drawing conclusions from the available observations. A location map, original field photographs, analytical results and references accompany the discussion. This complete 2024 USGS publication preserves the original data presentation and credits.
