Quick look: Use ‘ProjectAlert’ to keep up with USGS scientists as they respond to floods, droughts, and chemical spills. These alerts are official, yet informal notices that describe flood, drought, or water quality conditions across the country, as well as how USGS field crews are responding to the event....

Quick look: Scientists at the U.S. Geological Survey (USGS) use a range of research approaches to investigate the genetics of native and non-native species that are being managed. This Fact Sheet outlines those approaches and explains the type of information they provide. Genetic research for wildlife and fisheries management - A primer(Released: Tue, 25 Sep 2012 00:00 -0500)
Quick look: This report presents a brief summary of recent fieldwork conducted off Kahekili Beach Park, Maui, Hawaii, the site of the newly established U.S. Coral Reef Task Force priority study area at Kaanapali and the Hawaii Department of Land and Natural Resources, Division of Aquatic Resources, Kahekili Herbivore Fisheries Management Area (HFMA). The goals of this fieldwork are to provide new baseline inf Nearshore morphology, benthic structure, hydrodynamics, and coastal groundwater discharge near Kahekili Beach Park, Maui, Hawaii(Released: Mon, 24 Sep 2012 00:00 -0500)
Quick look: Surface nuclear magnetic resonance, a noninvasive geophysical method, measures a signal directly related to the amount of water in the subsurface. This allows for low-cost quantitative estimates of hydraulic parameters. In practice, however, additional factors influence the signal, complicating interpretation. The U.S. Geological Survey, in cooperation with the Central Platte Natural Resources Dis Quantification of aquifer properties with surface nuclear magnetic resonance in the Platte River valley, central Nebraska, using a novel inversion method(Released: Mon, 24 Sep 2012 00:00 -0500)
