Semi-Permeable Membrane Devices (SPMDs) were deployed for approximately 2 weeks at Palmyra Atoll during October and November, 2008. SPMDs passively accumulate organic compounds from the aquatic enviroment, and are then analyzed for various organic compounds. The deployment date, reasons for selecting the particular site, and photograph numbers as links are indicated.

Data set contains individual structures and use-areas identifiable from scanned images of 1944 hand-drawn map of buildings and facilities at Palmyra Atoll during World War II, at which time the atoll served as a training facility for the U.S. Navy. Scanned images were georeferenced against control points identifiable from 2007 QuickBird satellite imagery and on control points for which positional data were gathered during sampling in October and November 2008. Georeferenced image was then used to delineate individual structures and other areas as polygons. Attributes were taken from legend for 1944 map.

Soils and organismal tissue from known and potential sources of contamination at Palmyra Atoll were measured for concentrations of 13 elements using a hand-held X-Ray Flourometer (XRF). Measured elements include; Lead (PB), Arsenic (As), Cobalt (Co), Cromium (Cr), Copper (Cu), Antimony (Sb), Iron (Fe), Titanium (Ti), Zinc (Zn), Nickel (Ni), Manganese (Mn), Sulphur (S) and Phosphorous (P). Concentrations of other elements were excluded because they were below the limit of detection or were sporadically detected; these include Tin (Sn), Cadmium (Cd), Silver (Ag), Strontium (Sr), Ruthenium (Rb), Selenium (Se), Mercury (Hg), Vanadium (V), Scantium (Sc), Calcium (Ca), Potassium (K), and Chlorine (Cl). Attributes for...

ScienceBase brings together the best information it can find about USGS researchers and offices to show connections to publications, projects, and data. We are still working to improve this process and information is by no means complete. If you don't see everything you know is associated with you, a colleague, or your office, please be patient while we work to connect the dots. Feel free to contact sciencebase@usgs.gov.
