1. Sea-level fluctuations during the last glacial cycle.

    Nature 423(6942):853 (2003) PMID 12815427

    The last glacial cycle was characterized by substantial millennial-scale climate fluctuations, but the extent of any associated changes in global sea level (or, equivalently, ice volume) remains elusive. Highstands of sea level can be reconstructed from dated fossil coral reef terraces, and thes...
  2. Porphyrin and chlorin distributions in a Late Pliocene lacustrine sediment.

    Geochimica et Cosmochimica Acta 58(17):3691 (1994) PMID 11539149

    The tetrapyrroles in a highly immature Late Pliocene lacustrine sediment (Willershausen, Germany) show a simple distribution of both chlorin and porphyrin components as the free bases. The major components are C32 desoxophylloerythroaetioporphyrin (DPEP), a C33 bicycloalkano porphyrin, the chlo...
