6. Workshop Mission and Approach

7. Our mission is to understand the Greenland Ice Sheet
Its processes, and the ways it changes: past, present, and future
This workshop is a community space to strategize about that mission
● Identify the steps that our collective community can take to better empower
each of us to meet this Mission
The motivating questions for our workshop are twofold:
● What are the barriers to our collectively understanding the Greenland Ice
Sheet?
● What ought to be done to remove these barriers and accelerate our
understanding?

8. Last year at FOGSS, we identified the challenges to our
research
● Two-thirds of the 2022 workshop time was community generated or
community led
● Asked all participants to share their “big idea” or “grand challenge”
● Breakout sessions focused around sub-disciplinary themes
● Each sub-disciplinary theme identified where they want to be, what they
would like to achieve, what are their obstacles.

● Breakout sessions focused around sub-disciplinary themes
● Each sub-disciplinary theme identified where they want to be, what they
would like to achieve, what are their obstacles.
Each sub-disciplinary theme identified:
• Community interests
• The three biggest challenges our community faces
• Highest priority needs to observe and/or model
• A moonshot
• Immediate and decadal goals
• Desired broader impacts

challenges, that span scientific sub disciplines.
Last year at FOGSS, we identified the challenges to our
research

13. Challenge #1: Decolonizing U.S. research in Greenland
Problem: Current U.S. research in Greenland can run roughshod over local interests, with insufficient
engagement with local communities or attention to local capacity building.
Solutions:
Near-term
● Mandate U.S. participation in Greenlandic research portals (Isaaffik.org, ArcticHub.gl, g-e-m.dk)
● Establish policy guidance from U.S. funders about engagement with Greenlandic science offices.
● Identify and use a central communication hub to determine what different Greenlandic communities
need.
● Identify sustainable infrastructure support and local expertise to foster local networks.
Moonshot
● Establish a permanent U.S. scientific envoy to Greenland to facilitate and coordinate collaborative
U.S.–Greenland research activities for the mutual benefit of local communities.

14. Challenge #2: Better integration of observations and
models
Problem: At present, observational and modeling projects are often distinct, and with limited feedback
between new observations and modeling needs.
Solutions:
Near-term
● Prioritize efforts that tightly integrate observational and modeling approaches (e.g., Dear Colleague
letter).
● Prioritize efforts to test scaling up of individual processes at specific locations to regional or ice-
sheet-wide scales (e.g., terminus position prediction).
Moonshot
● Cloud-supported data structures and modular models, with notebook-style tutorials to facilitate data
and model exploration and experimentation by non-experts, facilitated by user-experience experts
resourced to break down access barriers.

15. Challenge #3: Water remains a unifying unknown
Problem: Increasing ocean heat transport and meltwater flux drives most change in the Greenland Ice
Sheet, yet the processes across these interfaces are hard to observe and not yet well-understood.
Solutions:
Near-term
● Prioritize study of mass and energy fluxes at interfaces (e.g., mélange dynamics and fjord
circulation, rainfall and albedo, firn aquifer evolution).
● Prioritize field observations that ground-truth remote sensing observations and numerical models,
along with databases of those efforts (e.g., a SUMup for Fjord Properties or Surface Meltwater).
Moonshot
● Identify and realize two new Greenland mega-sites as foci for studies of water fluxes, at sites distinct
from Helheim Glacier, e.g., Jakobshavn Isbræ, Petermann Glacier, or Isungata Sermia, in
collaboration with local communities.

16. Problem: Long-term observations of the Greenland Ice Sheet have improved significantly in recent
decades, but many needed observations (e.g., ice thickness, bathymetry, mass change from gravity,
AWS), are only tenuously available, unobservable from space, or insufficiently validated.
Solutions:
Near-term
● Establish a consensus framework for evaluating remote-sensing data with in situ observations
(could this be done via QGreenland?).
● Improved licensing of commercial data for polar observation (e.g., Maxar), with access to non-
governmental institutions.
● Identify at-risk, critical cryospheric observations and formulate plans to mitigate them.
● Request history of open science contributions from PIs, as a component of proposals.
Moonshot
● Community consensus time series of ice and water fluxes (e.g. IMBIE for X, where X is ice surface
velocity, elevation change, runoff) that combine data from multiple platforms and agencies.
Challenge #4: Sustained, open polar observations

17. Challenge #5: Projecting Greenland’s contribution to sea-
level rise
Problem: While ice-sheet models have increased resolution and sophistication, they still do not yet
adequately reproduce recent observed changes in ice-sheet mass balance.
Solutions:
Near-term
● Prioritize research on uncertainty quantification to better identify the best opportunities for
improvement in the performance of diverse models, e.g., do models need better forcings or better
physical process parameterizations?
● Prioritize paleo and modern data acquisition to better constrain paleo/modern ice sheet change.
● Grow the modeler pipeline and treat models as instruments that require maintenance to continue
operation.
Moonshot
● Establish an interagency National Center for Sea Level Change Research.

28. Code of conduct for breakout sessions
● Be excellent to each other
● Take action to hear the voices and perspectives of all participants
● Be generous and adopt a collaborative stance
● Think long-term, broadly, and blue-skies
● Within breakout groups, we recommend that you identify individuals for each of
the several possible roles below:
○ Moderator/Time keeper
○ Note taker (although we suggest that all contribute collaboratively to slides)
○ Reporter (for sharing back to main group, at large)
○ Equity monitor (to ensure that your group is hearing all voices)
