Abstract:
During Leg 119 of the Ocean Drilling Program (ODP), Quaternary sediments of the Southern Ocean were examined for the presence and abundance of Chaetoceros resting spores. Six drill sites were occupied along the Kerguelen Plateau. An additional five drill sites were clustered within Prydz Bay, Antarctica. Chaetoceros resting spores were present at all sites examined. These resting spore assemblages were comprised primarily of Chaetoceros neglectus and several unidentified Chaetoceros species. Resting spore assemblages accounted for approximately 20% of the total diatom assemblage (ranging from 0% to 91.4% of any given sample).
Quantitative estimates of resting spores demonstrated considerable downcore abundance fluctuations, ranging from 0 to 1.82*10*9 valves/g sediment. The highest spore production rates (3.75*10**12 spores/cm/yr) were found on the northern Kerguelen Plateau (Sample 119-736B-1H-3,35-37 cm). A lack of adequate chronological control at all sites prevented proper between-core comparisons. Mean resting spore abundance, however, appeared highest within the sediments of Prydz Bay and across the northern Kerguelen Plateau. Deep-water stations of the southern Kerguelen Plateau demonstrated the lower spore abundances and a reduction in the percentage contribution of spore to the total diatom assemblage.
