2010, Open-File Report 2009-1275
The Upper Floridan aquifer is contaminated with saltwater in a 2-square-mile area of downtown Brunswick, Georgia. This contamination has limited development of the groundwater supply in the Glynn County area. Hydrologic, geologic, and water-quality data are needed to effectively manage water resources. Since 1959, the U.S. Geological Survey has conducted...

Enumeration of viruses and prokaryotes in deep-sea sediments and cold seeps of the Gulf of Mexico
Christina A. Kellogg
2010, Deep-Sea Research Part II: Topical Studies in Oceanography (57) 2002-2007
Little is known about the distribution and abundance of viruses in deep-sea cold-seep environments. Like hydrothermal vents, seeps support communities of macrofauna that are sustained by chemosynthetic bacteria. Sediments close to these communities are hypothesized to be more microbiologically active and therefore to host higher numbers of viruses than non-seep...
Emergency use of groundwater as a backup supply: Quantifying hydraulic impacts and economic benefits
Eric G. Reichard, Zhen Li, Caroline Hermans
2010, Water Resources Research (46)
Groundwater can play an important role in water‐supply emergency planning. A framework is presented for assessing the hydraulic impacts and associated costs of using groundwater as a backup supply when imported‐water deliveries are disrupted, and for quantifying the emergency benefits of groundwater management strategies that enable better response to such...
Reconnaissance dating: a new radiocarbon method applied to assessing the temporal distribution of Southern Ocean deep-sea corals
Andrea Burke, Laura F. Robinson, Ann P. McNichol, William J. Jenkins, Kathryn M. Scanlon, Dana S. Gerlach
2010, Deep-Sea Research Part I: Oceanographic Research Papers (57) 1510-1520
We have developed a rapid 'reconnaissance' method of preparing graphite for 14C/12C analysis. Carbonate (~15 mg) is combusted using an elemental analyzer and the resulting CO2 is converted to graphite using a sealed tube zinc reduction method. Over 85% (n=45 replicates on twenty-one individual corals) of reconnaissance ages measured on...
Recent ecological divergence despite migration in sockeye salmon (Oncorhynchus nerka)
Scott A. Pavey, Jennifer L. Nielsen, Troy R. Hamon
2010, Evolution (64) 1773-1783
Ecological divergence may result when populations experience different selection regimes, but there is considerable discussion about the role of migration at the beginning stages of divergence before reproductive isolating mechanisms have evolved. However, detection of past migration is difficult in current populations and tools to differentiate genetic similarities due to...

Coral calcification in a changing ocean
Ilsa B. Kuffner
2010, Fact Sheet 2010-3098
Animals and plants that live in the ocean form skeletons and other hard parts by combining calcium ions and carbonate ions to create calcium carbonate. This process is called calcification. In tropical and subtropical oceans, the calcification of corals and other organisms creates reefs that protect islands, produce beautiful white-sand...
