AGU FALL MEETING
San Francisco, CA, December 9–13, 2013
Abstract Deadline – Tuesday, 6 August 2013
– SESSION P025: SATURN’S NORTHERN SPRING –FROM STORMS TO POLAR VORTICES
Conveners: Brigette Hesman, Kunio Sayanagi, Scott Edgington, and Kevin Baines
This session solicits presentations on new Cassini, Hubble, and ground-based observations and the subsequent analyses of Saturn’s atmosphere. The session will focus in particular on 1) the analysis of the great storm of 2010-2011 and its aftermath; and 2) new observation of Saturn’s north pole, which is in sunlight for the first time since Cassini’s arrival at Saturn.
– SESSION P026 : SHAPE, INTERNAL STRUCTURE, GRAVITY, AND WINDS OF JUPITER AND SATURN The Juno spacecraft is now on its way to Jupiter and the Cassini spacecraft will visit Saturn toward the end of its mission. One of the main scientific objectives of both missions is to understand the internal structure, gravity, and winds of Jupiter and Saturn. We welcome the submission of abstracts on the following topics:
(1) Analytical or numerical models of shape and internal structure of rapidly rotating Jupiter and Saturn;
(2) Relationship between the shape and internal structure of Jupiter and Saturn and their external gravity fields;
(3) Analytical or numerical models of winds/circulations of Jupiter and Saturn; as well as their effects on the zonal gravity coefficients of Jupiter and Saturn;
(4) Analytical or numerical models of convection/dynamo of Jupiter and Saturn;
(5) Any aspects of the Juno and Cassini missions that are related to shape, internal structure, gravity, and winds of Jupiter and Saturn.

– SESSION P033 – TRACKING DOWN LIFE: STAR BIOSIGNATURES, BIOMARKER SYSTEMS OR THE ENSEMBLE CAST?
Please consider submitting an abstract to the “P033 Tracking Down Life: Star Biosignatures, Biomarker Systems or the Ensemble Cast?” session at the AGU 2013 Fall Meeting, San Francisco, 9-12 December.
The session is a really comprehensive one about biosignatures and we have managed to persuade a stellar slate of Invited Abstracts from (in alphabetical order) Dave DesMarais, Danny Glavin, Chris McKay and Everett Shock who variously will give papers on biosignature-related topics (in alphabetical order) Instruments, Outer planets, Planetary analogs and Terrestrial planets.
Star quality biosignatures are unambiguous: preserved biomolecules, not possibly formed abiotically, but are hard to preserve. Mineral biosignatures (MBs), fossil inorganic metabolites, are robust but can be formed inorganically. But new analysis techniques can tackle preservation and origins. Systematic searches for signs of life should include all options. MBs may have biochemicals in them and so act as beacons or pathfinders to fossil ecosystems.
We seek abstracts on planetary analogs; ancient Earth; organic gaseous and mineral biosigs; biomarker systems – including non-Earth-centric; instruments; quantifying biosig distribution & chance of preservation; etc. We want a spectrum – stars, supporting actors or the ensemble.
