Some Lab News...
Connect with us at AGU (December 2024)!
Come and discuss our work! You can find us in many places, see below… We are also looking for new members to join our work, at the undergraduate, graduate and postdoctoral levels…
Some new papers... the best place to find out about our work is still google scholar (November 2024)!
Dynamic thickness change over an undulating bed. (a) Ice thickness, grounding line and calving front change over time. Smooth multi-year front retreat causes step changes in the grounding line, temporally matching the periods of faster and slower dynamic thinning. Time series are extracted at the location marked as a red circle in B and C. Colored dots over the grounding line are the same as those dots in panel B but are plotted here to better visualize the retreat distance.

Sources of uncertainty in ISMIP6 Antarctica experiments with high emission scenario forcings during 2015–2300. (a) Uncertainty from the climate model, ice model, inclusion of ice shelf collapse, and interactions between two or more components; the black line shows the total uncertainty. (b) Relative variance of the sources of uncertainty as a proportion of the total variance.

UB Climate-Glaciology Seminar (October 2024)!
Our lab is trying a new idea: we want to learn more from our peers, but we are also conscious about carbon footprint – Thus the UB Climate-Glaciology Seminar allows us to welcome remote speakers that are pursuing a PhD anywhere in the world .
Our first speaker was Andrés Castillo-Llarena, a PhD student at the University of Bremen (Germany), who gave a presentation on the modelling of the Patagonia Ice Sheet during Last Glacial Maximum.
NASA Sea Level Change Team celebrates 10 year (September 2024)!
Sophie N has been a science team member of the NASA Sea Level Change Team (N-SLCT) since its begining - 10 years ago... Time has flown by and the N-SLCT is behind the https://sealevel.nasa.gov/ portal. This time around, Sophie co-leads the WG1, which is tasked to deepen our knowledge of the Earth system interactions that influence relative sea level change and facilitate team wide research on this topic. The photo is the result of a mapping exercise of "whos who" and captures our team expertise...
The lab participates GLY Trick or Treat (September 2024)!
Why are Swedish Fish and Mount candy relevant to our lab?
... Apart from being yummy:
As sea level changes with melting ice, fish may have a different environment... and knowing sea floor topography is super important too :) ...
Our lab had fun welcoming students and faculty in the Geology "Trick or Treat" and talking about our work of understanding the recent, current and future states of the Greenland and Antarctic ice sheets (and hence sea level) using numerical models and observations.
Ana and Sophie N participate in IGS - Northumbria (August 2024)!
The International Symposium on Verification and Validation of Cryospheric Model from the International Glaciology Society was busy: Ana presented her work on Greenland historical initialization and Sophie presented Xiao's ice sheet model weighting work. Sophie co-organized an ISMIP7 workshop and accepted with Tony Payne and Heiko Goelzer the Richardson Medal on behalf of ISMIP6.
The lab plays a key role in ISMIP7 workshop (June 2024)!
The Ice Sheet Model Intercomparison Project for CMIP7 was officially launched in June 2024 at workshop sponsored by the Heising-Simons Foundation. Our lab played a key role in making this workshop a success: from the wifi logistics to organizing and participating in the scientific program. ISMIP7 is a follow to ISMIP6 - the first coordinated effort from the glaciology community to make projections of the sea level contribution arising from the Greenland and Antarctic ice sheets. ISMIP7 is a the ice sheet MIP for CMIP7 and is a targeted activity of CliC. Learn more about ISMIP7 on our wiki and join us!
Very excited to be part of EDGE Science Team (May 2024)!
The Earth Dynamic Geodetic Explorer (EDGE) was selected by NASA to put forward a concept study for a future satellite mission to help better understand how our planet is responding to climate change. Sophie N is the Cryosphere Application lead for EDGE. You can read more about EDGE here and UB research news and UB International.
Sophie N is a speaker and panelist at the "From Ice Sheets to the Coast: Sea-Level Rise Impacts" workshop (University of Houston, April 2024)!
See here for workshop goals... Sophie learned a lot!

Sophie G wins UB "art of research" competition
"Paint with all the colors of a glacier". The Landsat 8 Satellite collects spectral information of the Earth's surface in 11 spectral bands, each spanning a different segment of the electromagnetic spectrum. The aim of conventional cameras is to capture the world as our eyes see it, so they sense in the red, green, and blue wavelengths. Landsat can recreate the surface of the Earth to include to infrared wavelengths, which allow us to detect changes we cannot normally observe optically. In order to visualize these other wavelengths so our eyes can see them, we replace the Red, Green, or Blue channels in an image.
In this suite of images, different band combinations of Helheim glacier in Southwest Greenland are shown. Relative brightness and color in each of these images is due to the surfaces ability to reflect or absorb whatever wavelengths are included in each band composite. A true color or RGB image is located in the top left for comparison.
All of this data is free and publicly available. Landsat 8 Band combinations in increasing order, starting in the top-left corner: 432, 546, 676, 675, 615, 576, 652, 564, 416
ISMIP6 wins IGS Richardson Medal and ISMIP7 starts... (2023)
The entire ISMIP6 team is recognized for its academic and leadership activities in the design and production of future sea-level projections. This was a truly unexpected award for a group that begin in 2014...
Read the full description of the award on the IGS website and find out about ISMIP6 on our wiki!
