Deep Culture

Deep Culture

November 16, 2016

Katarzyna Melaniuk, a guest student visiting WHOI scientist Joan Bernhard‘s lab, examines cultures of single-celled foraminifera (forams) collected off Norway. She is investigating whether certain species live in chemosynthetic habitats, such as methane seeps. Melaniuk sets different carbon dioxide and oxygen levels in the culture boxes, mimicking different deep-sea habitats, and feeds the cultures either methane-consuming bacteria or surface-living algae. Analyzing foram growth and shell geochemistry will indicate whether they ate chemosynthetic bacteria and built carbonate shells at methane seeps.
