The speed of sound in supercritical, fluid oxygen has been measured up to the freezing points of 6.0 GPa at 30{degree}C and 10.5 GPa at 200{degree}C. The oxygen was contained in a diamond{endash}anvil cell and pressure was measured on the ruby scale. The measurements were used to establish an equation of state. Additionally, the fluid-{beta} phase boundary was determined between 15 and 180{degree}C to a precision of 0.02 GPa. {copyright} {ital 1999 American Institute of Physics.}
