Anny Cazenave(French pronunciation:[anikaznav]ⓘ) is a French spacegeodesistand one of the pioneers insatellite altimetry.She works for the French space agencyCNESand has been deputy director of theLaboratoire d'Etudes en Geophysique et Oceanographie Spatiales[fr](LEGOS) atObservatoire Midi-PyrénéesinToulousesince 1996. Since 2013, she is director of Earth sciences at theInternational Space Science Institute(ISSI), in Bern (Switzerland).

As one of the leading scientists in the joint French/American satellite altimetry missionsTOPEX/Poseidon,Jason-1,and theOcean Surface Topography Mission,she has contributed to a greater understanding ofsea level risecaused byglobal warming.Cazenave is a member of theIntergovernmental Panel on Climate Changeand was the lead author of the sea level sections for their fourth and fifth Assessment Reports.

Early life and education[edit]

Not from an academic background, Cazenave was not destined to work in the sciences.[1]However, she achieved a postgraduate doctorate in fundamental astronomy (Paris, 1969) as well as receiving her Ph.D. in geophysics from theUniversity of Toulousein 1975.[2]

Post-University[edit]

From 1975 until the mid-1990s, Cazenave researched temporal and spatial variations of gravity. She used satellite altimetry data fromSEASAT,ERS-1,andTOPEX/Poseidonto devise gravity models of deep ocean geodynamic processes. The models were used to investigate marine tectonic features such asgeoidheight variations acrossdeep ocean trenchesand fracture zones, lithospheric cooling andsubsidence,and the isostatic compensation ofseamountchains.[3]

Cazenave turned her focus to space oceanography in the 1990s. Using data sets from the satellite altimetry missions TOPEX/Poseidon,Jason-1,and theOcean Surface Topography Missionof Jason-2, she has addressed the problem ofglobal sea level rise.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 theGRACEsatellite system into her analyses. She has also been involved in studying terrestrial bodies of water from space.[3]Cazenave is interested in "measuring temporal changes of the Earth gravity field using spacegravimetryand in applications to ice sheet mass balance and change in total land water storage. "[4]

Cazenave is a member of theIntergovernmental Panel on Climate Changeand was the lead author of the sea level sections of the 2007IPCC Fourth Assessment Reportand the 2014IPCC Fifth Assessment Report.[5]Cazenave has called attention to the effects ofclimate changeon sea level rising. She has indicated that extremely flat regions such asBangladeshcould have their groundwater threatened by sea salinisation.[6]

Cazenave was elected to theFrench Academy of Sciencesin 2004.[7]She was the 2012 recipient of theWilliam Bowie Medal.She is foreign member of the National Academy of Sciences (USA), of the Indian National Academy of sciences (India) and Royal Academy of Belgium.

Selected works[edit]

Cazenave has authored more than 200 scientific articles for international peer-reviewed journals.
