Dr. Anny Cazenave, ISSI Earth Science Director, Receives the 2020 Vetlesen Prize for her Pioneering Work in Charting Modern Sea Level Change

Dr. Anny Cazenave is to receive the most prestigious Vetlesen Prize 2020 for Achievements in the Earth Sciences.

The Vetlesen Prize is designed to be equivalent to the Nobel prize and will be administered at a ceremony at Colombia University this spring. Cazenave, a geodesist by training,  will be honored for pioneering the use of space satellite data to measure the topography and the rise of the surface of the oceans, together with related changes in ice sheets, glaciers, ocean temperature and land water storage. Her work has linked the sea level rise with climate change.

Sea level rise is seen as one of the most important and threatening consequences of climate change. Two thirds of the sea level rise is now understood as coming from the melting of land ice as a direct consequence of global warming and one third from the expansion of ocean water. That ratio was only half to half when Cazenave started her work.


As director of ISSI’s Earth Science Program Anny Cazenave has supervised the program and has organized a significant number of workshops related to global change. ISSI is proud to have her on the scientific staff.

The Vetlesen Prize is awarded every three years for “scientific achievement resulting in a clearer understanding of the Earth, its history, or its relation to the universe”. The prize was established in 1955 by George Unger Vetlesen, a Norwegian born sailor, naval engineer and shipbuilder in the United States.

International Teams are small groups of scientists involved in space research, working together on data analysis, theories, and models. This call is open to scientists of any nationality, actively involved in any of the following research fields:
1. Space Sciences: Magnetospheric and Space Plasma Physics, Solar-Terrestrial Sciences, Solar and Heliospheric Physics, Planetary Sciences, Astrobiology, Astrophysics, Cosmology, and Fundamental Physics in Space
2. Earth Sciences using Space Data

Letter of Intent Submission Deadline: February 13, 2020

Proposal Submission Deadline: March 25, 2020

Surface Bounded Exospheres and Interactions in the Solar System

Workshop 20-24 January 2020

Studying the evolution of the surfaces and atmospheres of bodies in the solar system is fundamental to our understanding of the present state of the Solar System. The workshop focuses on the large subset of planets, moons and small bodies in the inner heliosphere that are not protected by either strong magnetic fields or thick atmospheres. We refer to these cases as surface-bounded exospheres, since the surface release processes supply the exospheric material, and atoms and molecules collide with the surface far more frequently than with each other.

Applications now open for Alpbach Summer School 2020 "Comparative Plasma Physics in the Universe" 14-23 July 2020

Would you like to use engineering and/or science to solve problems that can be addressed by space missions? If yes, consider applying to the Summer School Alpbach. This year, sixty European engineering and science students will be selected to participate in the 44th edition of the Summer School Alpbach. Participants will be engaged in an in-depth learning experience, attending stimulating lectures on relevant aspects of space science and engineering, and working intensely within four groups to define and design a space mission under the supervision of noted scientific and engineering experts.

Application Deadline: March 31, 2020

What to expect:
• 10 day learning experience, attending lectures and working intensely within groups to defi ne and design a space mission under the supervision of experts
• formulate observational objectives to advance the understanding of the behaviour and the coupling processes of plasma at several astrophysical scales (Earth, Planets, Sun, Across the Universe)
• Presentation of a mission study to an expert review panel on the last day

Ionospheric Multi-Spacecraft Analysis Tools >>

Approaches for Deriving Ionospheric Parameters

edited by

M.W. Dunlop and H. Lühr

This ISSI Scientific Report provides a comprehensive toolbox of analysis techniques for ionospheric multi-satellite missions. The immediate need for this volume was motivated by the ongoing ESA Swarm satellite mission, but the tools that are described are general and can be used for any future ionospheric multi-satellite mission with comparable instrumentation.


Pro ISSI Talk with Anny Cazenave (recorded on October 30, 2019)

Abstract:  It is now well established that the Earth‘s climate is warming and that the main reason is the accumulation inside the atmosphere of green house gases produced by anthropogenic fossil fuel combustion and change in land use. Global warming has already several visible consequences, in particular increase of the Earth’s mean temperature and of ocean heat content, melting of glaciers, and ice mass loss from the Greenland and Antarctica ice sheets. Ocean warming causes thermal expansion of sea waters, hence sea level rise. Similarly, land ice melt that ultimately reaches the oceans, also causes sea level to rise. 

In this presentation, we summarize the most up-to-date knowledge about climate change and associated impacts on ocean warming, land ice melt and sea level rise. We highlight the contribution of space observations, in particular from satellite altimetry and space gravimetry, to measure ice sheet mass loss and sea level rise. We also discuss the various causes of sea level rise at global and regional scales and show that in terms of global average, we are now able to close the sea level budget. Finally, we discuss the importance of measuring sea level change at the coast, as well as the many complex processes at work in such regions (due to natural phenomena and anthropogenic forcing) that cause important adverse effects and significant vulnerability to coastal populations.

Saturn’s moon Mimas, a Snowplough in the Planet’s Rings

The Solar System's second largest planet both in mass and size, Saturn is best known for its rings. These are divided by a wide band, the Cassini Division, whose formation was poorly understood until very recently. Now, researchersfrom the CNRS, the Paris Observatory – PSL and the University of Franche-Comté have shown that Mimas, one of Saturn's moons, acted as a kind of remote snowplough, pushing apart the ice particles that make up the rings.  The findings are the result of two studies supported by the International Space Science Institute and CNES, the French space agency, published simultaneously in June 2019 in Monthly Notices of the Royal Astronomical Society.
