In addition to our bi-weekly M3OCCA seminar lectures, we invited Jürgen Merz to present his “Glacier project”.
He is a photographer specializing in abstract art. Within his “Glacier project”, he documented the fragile beauty and changes of alpine glaciers.

Abstract:
The Antarctic coastline is constantly changing. Three-quarters of the coastline are fringed by ice shelves, the floating extensions of the Antarctic ice sheet. The retreat or disintegration of ice shelves with buttressing forces cause enhanced mass loss of the Antarctic ice sheet increasing global sea level rise. Continuously tracking ice shelves is challenging because manual mapping cannot keep up with growing satellite archives and automated approaches fail due to the complexity of the Antarctic coastline. Recent advances in deep learning and easy access to high performance computing facilitated a fully-automated framework able to regularly monitor Antarctic ice shelf front dynamics. This presentation explores the unprecedented dense time series of calving front change providing new insights into ice shelf front dynamics and establishes links to ice dynamical and environmental controls on ice shelf extents.
The Institute of Geography at FAU Erlangen-Nürnberg will host an invited talk by Dr. Samuel Cook (Univ. Lausanne).

Abstract:
I present my ongoing work using the emulator from the Instructed Glacier Model (IGM) (https://github.com/jouvetg/igm) to invert for ice thickness at the 200,000 glaciers in the world outside the polar ice sheets. The basis of the emulator is a convolutional neural network trained on the outputs of full-Stokes simulations of real glaciers. Provided with surface velocities – taken from the new global dataset compiled by Millan et al. (2022) – and surface DEMs, this emulator can invert for thickness at any glacier in the world with a comparable accuracy to traditional full-Stokes inversion, but at a fraction of the computational cost. This allows us to greatly improve our estimates of global glacier volume, vital both for prediction of sea-level rise, but also for local communities in mountainous areas, who often rely on glacier melt for a large proportion of their water resources. I will discuss the rationale and methods behind my work, as well as preliminary results and the problems I’m currently working on.
In cooperation with the library of FAU, we organized a two days workshop.
It covered various topics like scientific data and literature management as well as open access publishing and bibliometry.
The first annual Retreat within the IDP M3OCCA took place at “Studienzentrum Josefstal” in early November 2022.
During the workshop, all Ph.D. students provided an overview of their individual PhD projects with subsequent discussions.
Additionally, further steps within the IDP M3OOCA program were discussed and defined.
Right to the beginning of the IDP M3OCCA, we organized a “kick-off” workshop at FAU Erlangen in June 2022.
The workshop was the first gathering of all IDP M3OCCA Ph.D. students, including affiliated Ph.D. students. Many subproject supervisors were also around, so the workshop provided the fundament for a fruitful exchange and collaboration between all different institutions involved in the IDP M3OCCA.
