[AGU 2026] SESSION EP019: HIDDEN ICE AND FROZEN GROUND - SUBSURFACE
GLACIAL AND PERIGLACIAL PROCESSES ACROSS EARTH AND PLANETARY
ENVIRONMENTS

Buried ice features, including the rock glacier to debris-covered
glacier continuum, have been increasingly recognized for their
significance in high-mountain ecosystems. Due to their higher
resilience to climate change than clean ice, they will be key future
water sources. Additionally, some surface ice may be buried and
preserved as climate change progresses. As a community, we lack
fundamental knowledge about the formation, preservation, mechanics, and
impacts on biological systems of these features. The goal of this
session is to work towards creating a holistic view of buried ice in
cryospheres and its influences on local and downstream environments
through an interdisciplinary session. We welcome presentations on
scientific results or equipment development targeting buried ice in
terrestrial and other planetary environments, such as debris and ice
thickness, sub-debris hydrology, water resource management, glacial
geochemistry, biology, and buried ice features as planetary analogs and
astrobiology studies.

[AGU 2026] SESSION P005: DUAL-SPACECRAFT EXPLORATION OF JUPITER'S ICY
MOONS - SYNERGIES FROM EUROPA CLIPPER AND JUICE

https://agu.confex.com/agu/agu26/prelim.cgi/Session/282402

We herewith invite you to submit an abstract to session P005 on the
synergies of JUICE and Europa Clipper for the upcoming AGU26 Fall
Meeting (San Francisco, CA | December 7-11, 2026). The submission
deadline is Wednesday, August 5, 2026, at 23:59 EDT (Thursday, August 6
at 05:59 CEST / 03:59 UTC).

Jupiter's icy moons are prime targets for understanding the potential
for habitable environments beyond Earth. Europa Clipper and Jupiter Icy
Moons Explorer (JUICE) are designed to address these questions, with
arrivals in the Jovian system in April 2030 and July 2031,
respectively. This session invites contributions aligned with these
missions' objectives, including investigations of surface properties,
internal structures, subsurface ocean dynamics, and implications for
habitability. We also welcome studies of interactions with Jupiter's
space environment and long-term evolution within the Jovian system.
Abstracts on cruise-phase science are also encouraged, including
gravity-assist observations, studies of 3I/ATLAS, and heliophysics
investigations. As we enter an era of dual-spacecraft exploration,
this session will highlight complementary capabilities and the
synergistic science enabled by combined observations.

[AGU 2026] SESSION P022: PROCESSES IN THE PRESENT-DAY ATMOSPHERE OF
MARS

Observations from Mars orbiters, landers, and rovers have been
providing a wealth of information on the Martian atmosphere. Current
assets at Mars include weather stations on Mars rovers as well as Mars
orbiters that provide perspectives from various orbits. Their
measurements cover atmospheric regions from the near surface to the
upper atmosphere and span several Mars years and solar cycles. While
observations have led to considerable progress in understanding the
structure and variability of the Martian atmosphere, the challenges of
today are the identification and quantification of the underlying
dynamical, chemical, and radiative processes that govern the Martian
atmosphere. This session solicits observational and theoretical
contributions that provide deeper insights into these processes in the
present-day atmosphere of Mars. This includes studies on the
connections between the upper and the lower atmospheres and on
processes leading to upper atmospheric escape to space.

Abstracts are due Wednesday, 5 August at 23:59 EDT / 03:59 UTC.
