SPMD samples Palmyra Atoll 2008 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.

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.

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).

Before sampling, at least three times the water volume in the well casing was purged and field parameters (temperature, dissolved oxygen, specific conductance, and pH) were stable. Two samples from each well were collected into unpreserved 1 L amber bottles and shipped on ice overnight to a commercial lab. The two samples were extracted using dichloromethane (DCM; EPA Method 3510). One sample extract was treated with silica gel cleanup (SGC) column (USEPA method 3630C). Aliquots of the...

This data also describes RFUs of bovine serum albumin standards which were used to convert the RFUs of the cell lysates to protein with which to normalize the RLUs of the cell lysates.
