Anny Cazenave is a French space geodesist and one of the pioneers in satellite altimetry. She works for the French space agency CNES and has been deputy director of the Laboratoire d'Etudes en Geophysique et Oceanographie Spatiale (LEGOS) at Observatoire Midi-Pyrénées in Toulouse since 1996. As one of the leading scientists in the joint French/American satellite altimetry missions TOPEX/Poseidon, Jason-1, and the Ocean Surface Topography Mission, she has contributed to a greater understanding of sea level rise caused by global warming. Cazenave is a member of the Intergovernmental Panel on Climate Change and was the lead author of the sea level sections for their fourth and fifth Assessment Reports. ==Biography== Cazenave received her Ph.D in Geophysics from the University of Toulouse in 1975.〔(【引用サイトリンク】url=http://www.academie-sciences.fr/academie/membre/CazenaveA_bio022011_gb.pdf )〕 From 1975 until the mid-1990s, Cazenave researched temporal and spatial variations of gravity. She used satellite altimetry data from SEASAT, ERS-1, and TOPEX/Poseidon to devise gravity models of deep ocean geodynamic processes. The models were used to investigate marine tectonic features such as geoid height variations across deep ocean trenches and fracture zones, lithospheric cooling and subsidence, and the isostatic compensation of seamount chains. Cazenave turned her focus to space oceanography in the 1990s. Using data sets from the satellite altimetry missions TOPEX/Poseidon, Jason-1, and the Ocean Surface Topography Mission of Jason-2, she has addressed the problem of global 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 the GRACE satellite system into her analyses. She has also been involved in studying terrestrial bodies of water from space.〔 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."〔(【引用サイトリンク】url=http://www.nasonline.org/member-directory/members/20007153.html )〕 Cazenave is a member of the Intergovernmental Panel on Climate Change and was the lead author of the sea level sections of the 2007 IPCC Fourth Assessment Report and the 2014 IPCC Fifth Assessment Report. Cazenave has called attention to the effects of climate change on sea level rising. She has indicated that extremely flat regions such as Bangladesh could have their groundwater threatened by sea salinisation. Cazenave was elected to the French Academy of Sciences in 2004.〔(【引用サイトリンク】url=http://www.cnes.fr/web/CNES-en/3025-pr66-2004-anny-cazenave-elected-at-the-french-science-academy.php )〕 She was the 2012 recipient of the William Bowie Medal. 抄文引用元・出典: フリー百科事典『 ウィキペディア（Wikipedia）』 ■ウィキペディアで「Anny Cazenave」の詳細全文を読む スポンサード リンク
