She was among the first scientists to use the satellite altimetry data to extrapolate a rate of sea level rise of approximately three mm/year. She addressed the problem of balancing the global sea level budget by incorporating time-dependent gravity field data from the GRACE satellite system into her analyses. She has also been involved in studying terrestrial bodies of water from space.[1] Cazenave is interested in "measuring temporal changes of the Earth gravity field using space gravimetry and in applications to ice sheet mass balance and change in total land water storage."[4]
