(a)=Estimate isotope ratios at low concentrations (H)=Sample was prepped or analyzed beyond the specified holding time mg/L=milligrams per liter µg/L=micrograms per liter DUP=Duplicate *=Samples with ratios of 11C/12C>0.0112372 are positive;<0.0112372 are negative values. %oPDB= The standard is defined as O%o. For carbon,the international standard is Pee Dee Belemnite, a carbonate formation whose generally accepted absolute ratio of 13C/12C is 0.0112372. %oSMOC=The standard is defined as 0%o. SMOC is Standard Mean Ocean Chloride.
