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.

Abundance estimate as follows: - = not found, + = single specimen, R = rare (2-5), F = few (6-10), C = common (11 -25), A = abundant (>25) specimens per 27 mm x 46 mm slide.
