    Description: Originally issued as Reference No. 66-27, series later renamed WHOI-.
    Description: Largely for reason of limited space, scientific journals can only accept brief articles. Thus full accounts on analytical techniques, data files, and other details are frequently omitted, and pertinent information may be lost. Although this information is only of peripheral interest to the general reader, to the fellow scientist it is of vital significance. In order to serve both the specialist and the general reader, we have prepared a series of manuscripts dealing exclusively with either background information or the actual interpretation and discussion of the data. The present report is aimed chiefly at the specialist interested in calcification processes in biological systems, in molluscan ecology and phylogeny, and in amino acid analyses. It incorporates information on: (a) type, locality, and environment of sample material, (b) analytical techniques, (c) utilization of a digital computer and (d) quantitative amino acid analysis in the form of data sheets, i,e. computer printouts.
    Description: The work was supported by grants from the National Aeronautics and Space Administration (NSR-22-014-001) and the American Chemical Society (PRF-1943-A2).

    Description: Originally issued as Reference No. 68-4, series later renamed WHOI-.
    Description: In February-March 1965, a series of piston cores were taken aboard ATLANTIS II off the coast of Arabia, Pakistan, and India (Figure 1) in water depths of about 3,000 meters. The principal objectives of this program were (a ) to obtain information on the change in petrology of the sediments as a function of geography and depth (b) to study the microfauna in the sediment profiles, and (c) to apply geochemical tools for the elucidation of the diagenetic fate of the organic matter and the history of the sediments. This article presents data on the geochemical part of the project. Principally, we are concerned with the oxygen and carbon isotope distribution in carbonates, the carbon isotope composition of sedimentary organic matter, and the amino acid composition of the sediment material. These studies represent a part of a larger program at our Institute which is concerned with the distribution of (a) stable isotopes and (b) organic compounds such as amino acids, carbohydrates, or hydrocarbons in recent and ancient sediments, natural waters, and marine organisms.

In: Kastens, KA; Mascle, J; et al. (eds.), Proceedings of the Ocean Drilling Program, Scientific Results, College Station, TX (Ocean Drilling Program), 107, 591-602, https://doi.org/10.2973/odp.proc.sr.107.143.1990

    Description: Sediment and interstitial water from Sites 651 and 653 (ODP Leg 107) were investigated by organic geochemical methods to characterize labile organic compound classes (amino compounds and carbohydrates) and to evaluate their progressive diagenetic and thermal degradation in deep-sea sediments. Downhole distribution of dissolved organic carbon (DOC) appears related to redox zones associated with bacterial activity and of diagenetic recrystallization of biogenic tests and not so much to organic matter concentrations in ambient sediments. DOC ranges from 250 to 8300 µmol/L (3-100.1 ppm). Amino acids contribute 10%-0.3% of DOC; carbohydrates range from 78 to 5 µmol/L. Rate of degradation of amino acids by thermal effects and/or bacterial activity at both sites (significantly different in sedimentation rates: average 41 cm/1000 yr in the top 300 m at Site 651, average 3.9 cm/1000 yr in the Pliocene/Quaternary sequence at Site 653 to 220 mbsf) is more dependent on exposure time rather than on the depth within the sediment column. Variability in neutral, acidic, and basic amino acid fractions of total amino acids (with a range of 1.1-0.02 µmol/g sediment; up to 2.5% of organic carbon) varies with carbonate content and by differences in thermal stability of amino acids. Distribution patterns of monosaccharides are interpreted to result from differences in organic matter sources, sedimentation rates, and the degree of organic matter decomposition prior to and subsequent to burial. Total particulate carbohydrates range from 1.82 to 0.21 µmol/g sediment and contribute about 8% to the sedimentary organic matter. Investigation of trace metals in the interstitial waters did not show any correlation of either DOC, amino compounds, or carbohydrates.
