Christina Riesselman is an American paleoceanographer whose research focus is on Southern Ocean response to changing climate.

[1] Following postdoctoral work as a Research Scientist with the US Geological Survey, she moved to the University of Otago, New Zealand in 2013.

[4] Riesselman uses diatom micropaleontology and stable isotope geochemistry in marine sediments to examine the evolution of the Antarctic cryosphere through the Cenozoic.

[7] Riesselman with her husband, Chris Moy, a University of Otago paleoclimatologist, were among the 30 researchers on a 2019 voyage of the JOIDES Resolution.

The aim of the voyage, according to Reisselman, was to figure out how ocean circulation behaved during past warmer climates, up to three million years ago.
