Process_Description:
No specific information is available for cores from this cruise. General analytical techniques for the USGS Menlo Park Sediment Laboratory: Initial splits into size fractions by wet sieving using A.S.T.M. #10 (2mm) and A.S.T.M. #230 (0.063 mm) sieves. Fraction specific techniques for particle size analysis: for the coarse fraction (> 2.0 mm) is by sieve analysis and the medium fraction (2-0.063 mm) by settling tube. The fine fraction (<0.062 mm) is by pipette (Folk, 1968; Carver, 1971), hydrophotometer (Jordan and others, 1971), laser-diffraction (Beckman Coulter), or Sedigraph (Micromeretics), or combinations thereof. Settling tubes are modifications of those described by Theide, Chriss, Clauson and Swift, 1976 and are calibrated using Gibbs, 1971. Since 1998, the fine fraction (silt and clay), and occasionally up to 1 mm, is usually analyzed by the Beckman Coulter LS100Q (1 mm - 0.4 microns) and the LS230 (2 mm to 40 nanometers). Between 1993 and 1998, the fine fraction (0.063 mm to 1 micron) was generally analyzed by SediGraph (Micromeretics 5100. Between 1976 and 1995, the fine fraction was generally analyzed by hydrophotometer (Jordan and others, 1971). Data reduction, size analysis, and statistics performed by the SDSZ computer program (McHendrie, 1988). Carbon analyses by UIC Coulometrics (Joliet, IL) carbon analyzers, using protocols described in the UIC CM5012 and 5014 Coulometer instruction manuals (systems CM130, CM150, or CM250). Total carbon (TC) and total inorganic carbon (TIC) are determined by coulometric titration using Coulometer coupled to an acidification module and furnace apparatus. TC and TIC analyses are conducted separately on sediment samples. TC content is measured by combusting a sample (~20 mg) in a furnace preheated to 1000 degrees C until no more CO2 is evolved (~ five minutes). TIC content is measured using a heated perchloric acid digestion until no more CO2 is evolved (~ five minutes). Total organic carbon (TOC) content in sediments is calculated by difference (TOC = TC - TIC).
