TABLE 10C. Trace-element data for samples from core SB1a, St. Bernard Parish, Louisiana. | ||||||||||||||||
St. Bernard core SB1a (location: 29o58"53' N., 89o55"27' W; sampled 03/18/1996). Percent compaction (applied linearly): 6.8. Element concentrations reported in micrograms per gram (mg/g, equivalent to parts per million [ppm]). Silver (Ag) concentrations were <1 mg/g for all samples, so the data column is not shown. | ||||||||||||||||
