Planetary oceanography is a developing field of study full of opportunities for discovering and understanding new phenomena that might be observed by future missions. I will describe laboratory measurements of sound velocities in simulated icy world ocean solutions at relevant pressures, temperatures, and compositions, leading to self-consistent thermodynamic data sets. Applications of results from this work constrain the configuration of oceans and ices in Ganymede, and provide new insight into the structure of Europa’s ocean and its interaction with the overlying ice.
