Talks on GIA
The online seminar series “Talks on GIA” focuses on the broad topics of glacial isostatic adjustment (GIA), cryospheric deformation and their interactions with sea-level change. It aims to be a low-barrier online exchange format for the highly multifaceted community around GIA. The online seminars are an offer for the entire global community and allow the community to exchange without financial barriers. The design of the individual seminars was chosen in such a way that, wherever possible, a tandem of a more experienced researchers and an early career scientists give a coordinated presentation. This makes it possible to offer a stage to early career researchers to present their work and put it up for discussion, alongside people who are already better known in the community. In addition, the presentations in this format allow aspects to be presented in more detail than is possible, for example, with oral presentations at conferences.
