---DATA SET OVERVIEW:
This data set contains marine sediment chemistry from the Chukchi Sea. Data
are concentrations of metals and organic substances in the surface sediments
(top 1 cm) for 19 metals (Ag, Al, As, Ba, Be, Cd, Cr, Cu, Fe, Hg, Mn, Ni, Pb,
Sb, Se, Sn, Tl, V, Zn), total polycyclic aromatic hydrocarbons (PAH), and 34
individual compounds. These data were collected from 27 July 2009 through 16
August 2010.

The metals concentrations for Ag, As, Ba, Be, Cd, Cr, Cu, Hg, Mn, Ni, Pb, Sb, 
Se, Sn, Tl, V, and Zn are all ppm (µg/g) dry weight. Concentrations of Al, Fe, 
sand, silt+clay (siltclay) and TOC are all percent (%) dry weight. The 
concentrations of all hydrocarbon contaminants are ppb (ng/g) dry weight.

ppm = parts per million
ppb = parts per billion
