(eds.), Proceedings of the Ocean Drilling Program, Scientific Results, College Station, TX (Ocean Drilling Program) 133 https://doi.org/10.2973/odp.proc.sr.133.222.1993 175-180 Analyses of living benthic ostracodes collected in the Coral Sea show a direct relationship between water temperature and the Mg/Ca ratio in the ostracode shells. Fossil ostracodes from Hole 822A (western edge of the Queensland Trough) were analyzed for their Mg and Ca content, and paleotemperatures are inferred using equations derived from the modern material. The bottom-water temperature record from Site 822, spanning the last 120,000 yr, indicates substantial cooling during glacial periods. It also documents important variations during an interval that is considered to correspond to isotopic stage 5. Although still preliminary, these results show that trace-element analyses of ostracode shells have a great potential for paleoceanographic studies. 146.215 146.215 -16.423 -16.423 146.215 -16.423 1990-09-17T00:00:00 1990-09-20T00:00:00 0.1 27.0 vertical profile ODP Ocean Drilling Program https://www-odp.tamu.edu:443/ Ocean Drilling Program, Texas A&M University ODP http://www-odp.tamu.edu/ https://ror.org/01f5ytq51 133-822 -16.423 146.215 Coral Sea -967.0 1990-09-17T00:00:00 1990-09-20T00:00:00 Leg133 Leg133 1990-08-04T00:00:00 1990-08-04 1990-10-11T00:00:00 1990-10-11 Joides Resolution https://www-odp.tamu.edu:443/resolutn.html McKenzie, Judith A McKenzie, Judith A Davies, Peter J Davies, Peter J doi:10.2973/odp.proc.ir.133.1991 Joides Resolution https://www-odp.tamu.edu:443/resolutn.html Composite Core COMPCORE 433.9 m 387.5 m 47 cores; 433.9 m cored; 0 m drilled; 89.3% recovery 331 CC-BY-3.0 Creative Commons Attribution 3.0 Unported https://creativecommons.org/licenses/by/3.0/ Sediment depth is given in mbsf.
