he amount of Total Organic Carbon (TOC) was measured in both Dunkirk and
Hume samples. TOC was analyzed with a CM 5120 TOC analyzer. This analysis yields
total carbon (i.e. carbon from carbonates and organic matter). To obtain a precise TOC
measurement the Total Inorganic Carbon (TIC) was also measured on the CM 5120 TIC
analyzer and the values were subtracted from the TOC.
