Siliceous Microfossils

Very low radiolarian abundance was encountered at both sites. The New Harbour assemblage is dominated by Lithelius nautiloides Popofsky, the remaining taxa being Antarctic strelkovi Petrushevskay, Spongotrochus glacialis Popofsky and Spongodiscus cf. favus Ehrenberg. At Butter Point, Radiolaria were of even lower abundance than at New Harbour. The New Harbour assemblage is dominated by Lithelius nautiloides Popofsky, with Spongotrochus glacialis Popofsky and Antarctissa cf. denticulata (Ehrenberg) present. The diatom taxa, Coscinodiscus lentiginosus McCollum, Eucampia balustrum McCollum, C. sellaris McCollum, Charcotia irregularis Peragallow, Pseudoenotia sp and Denticula sp occur in the Butter Point sample.
