A preliminary investigation of the surficial sediments at the SEALAB III Test Site shows the textural, compositional, and engineering properties to be uniform in both makeup and distribution. Sands and silty sands are the dominant textural grade. Mean diameters range from 0.09 to 0.25 mm. Carbonate content ranges from 55 to 78 percent. The carbonate in the form of biogenic calcite. Detrital silicates (feldspars, quartz, illite, and chlorite) and minor amounts of organic matter are the remaining constituents present. Wet unit weights and water contents (percent dry weight) on individual samples range from 1.56 to 1.71 g/cucm and from 45 to 77 percent, respectively. Direct shear tests were performed on a prepared sediment sample to determine the range of angles of internal friction. (Author).

This partially annotated bibliography contains the first 1000 references from a computerized file of literature on the global ecological implications of carbon cycles and climatic changes. Many early citations originated from the Biogeochemical Ecological Information Center established at Oak Ridge National Laboratory in 1968 and from profiles of computerized files such as Government Research Abstracts (GRA) and Biological Abstracts (BA). Later citations have been extracted from the open literature through 1978 and early 1979, from government reports and impact statements, and from profiles of GRA, BA, and the Energy Data Base of the Department of Energy Technical Information Center, Oak Ridge, Tennessee. The subject categories covered by this bibliography may be divided into two main topics: carbon cycling and climate system analysis. Volume I contains an introduction and overview. Volume 2 contains an alphabetical (by author) listing of citations. Volume 3 provides indexes for author, organization (corporate authority), keywords (or free index terms), taxonomic category, subject category, Chemical Abstracts codes, Biological Abstracts codes (crosscode), and COSATI/Weekly Government Abstracts codes concentrated with permuted title words.
