Tetrapyrrole Pigments in DSDP Leg 38 Sediments

Abstract

Thirty-four cores from eight sites drilled in the Norwegian-Greenland Sea were examined for tetrapyrrole pigment content. (See Table 1 for sample description.) The major thrust of this investigation was to discover the distribution of tetrapyrrole pigments with respect to geologic age and depth of burial. The bulk of the conclusions drawn here is based on the UV-visible absorption data obtained from the core extracts.
