Quaternary radiolarians in the western Woodlark Basin, southwest Pacific (ODP Leg 180)

Abstract

Cores from the 11 sites drilled during Leg 180 showed radiolarian assemblages that appear only in the Quaternary sediments. The most diverse and well-preserved assemblages were found in hemipelagic sediments from Holes 1108A, 1110A, and 1115B.

Raman Spectroscopy Analysis of Botryococcene Hydrocarbons from the Green Microalga Botryococcus braunii

“…1A). Once produced, C 30 botryococcene is further metabolized by methylation at carbons 3, 7, 16, and 20 to produce C 31 , C 32 , C 33 , and C 34 botryococcenes (19,43,44), and even further methylated to C 36 and C 37 botryococcenes in some B race strains (22,45). In C 34 botryococcene-producing strains such as the Berkeley (Showa) strain, the majority (Ͼ99%) of the C 34 botryococcenes exist in the extracellular matrix whereas the intracellular oil comprises predominantly the lower carbon number botryococcenes (19,20).…”
