Multiple measurements of oxygen consumption in a single sea urchin, Heliocidaris erythrogramma, obtained using intermittent flow respirometry. The experiment was conducted at the Sydney Institute of Marine Science in Sydney, Australia. There are a total of 3 replicates showing declining oxygen, separated by flushes where new water was added showing increasing oxygen. Data was collected using a Vernier Optical DO probe (ODO-BTA).
