L.E. Osterman, R.Z. Poore, P.W. Swarzenski
2010, Open-File Report 2008-1099
An area of oxygen-depleted bottom- and subsurfacewater (hypoxia = dissolved oxygen < 2 mg per Liter) occurs seasonally on the Louisiana shelf near the Mississippi River. The area of hypoxia, also known as the 'dead zone,' forms when spring and early summer freshwater flow from the Mississippi River supplies a...

2010, Circular 1346
Summary of Major Findings and Implications About 105 million people in the United States-more than one-third of the Nation's population-receive their drinking water from about 140,000 public water systems that use groundwater as their source. Although the quality of finished drinking water (after treatment and before distribution) from these public water...
Isotopic characterization of flight feathers in two pelagic seabirds: Sampling strategies for ecological studies
Anne E. Wiley, Peggy H. Ostrom, Craig A. Stricker, Helen F. James, Hasand Gandhi
2010, The Condor (112) 337-346
We wish to use stable-isotope analysis of flight feathers to understand the feeding behavior of pelagic seabirds, such as the Hawaiian Petrel (Pterodroma sandwichensis) and Newell’s Shearwater (Puffinus auricularis newelli). Analysis of remiges is particularly informative because the sequence and timing of remex molt are often known. The initial step,...
