Stable isotopes in opal in the Southern Ocean, supplement to: Jacot des Combes, Hélène; Esper, Oliver; De La Rocha, Christina L; Abelmann, Andrea; Gersonde, Rainer; Yam, Ruth; Shemesh, Aldo (2008): Diatom d13C, d15N, and C/N since the Last Glacial Maximum in the Southern Ocean: Potential impact of species composition. Paleoceanography, 23(4), PA4209
Measurements of delta 13C, delta 15N, and C/N on diatom-bound organic matter were made over the Holocene and Last Glacial Maximum (LGM) from 3 piston cores in the Southern Ocean, one from each of the three sectors. The site in the Scotia Sea differed considerably from the other two sites by having m...
