Cosmogenic radionuclides (CRN) are rare isotopes created by the collision of high-energy cosmic rays with target atoms present either in the atmosphere producing meteoric CRNs or in mineral grains producing in situ CRNs.

From the point of view of an external observer in orbit around Earth, sea ice is an ultra-thin layer capping the polar oceans. This layer regulates the interactions between the atmosphere and the ocean. However, when taking a closer look, sea ice appears as a heterogeneous material governed by complex dynamic and thermodynamic processes on a wide range of scales.

In the context of our academic work, the publication of our research is crucial. The landscape of scientific publishing is constantly evolving, and it is important to understand the implications of the choices we make as authors. Two major options are available to us: traditional publication in paywalled journals and open access publication.

The excess freshwater in the Arctic due to global warming is causing a weakening of the Atlantic Meridional Overturning Circulation (AMOC). The question of how climate change will impact the stability of the AMOC, however, remains unclear.
