Short summary
Short summary
We conducted a survey on the topic of “interdisciplinarity” among early-career researchers in order to learn about their experiences. There are very different views on what interdisciplinarity means and many positive aspects are cited that enhance research, but there are also a few obstacles when it comes to communication, time management, and publication. It is precisely these obstacles that should be given greater consideration in education and research funding.

We investigate the reaction of salt structures on ice sheet transgressions. We used a series of sandbox models that enabled us to experiment with scaled-down versions of salt bodies from northern Germany. The strongest reactions occurred when large salt pillows were partly covered by the ice load. Subsurface salt structures may play an important role in the energy transition, e.g., as energy storage. Thus, it is important to understand all processes that affect their stability.

Short summary
Berlin’s parks are vital for recreation, biodiversity, and climate resilience, yet they face growing challenges from socio-economic inequalities and climate change. Our review examines how factors like gentrification and extreme weather impact access to and sustainability of these parks. By analysing over 200 studies, we highlight the need for inclusive policies, community engagement, and climate-adaptive park designs to ensure that Berlin’s parks remain accessible, resilient, and socially just.

Short summary
Depositional single-grain feldspar luminescence ages reveal the filling of a glacially overdeepened basin during Marine Isotope Stage 8, representing rare evidence of this time frame in the northern Alpine foreland. Reflection seismic surveys revealed two cross-cutting glacial basins. The dated sediments reveal significantly younger ages than previously assumed. This represents a first step in a re-evaluation of the established Quaternary depositional chronology of the Bavarian Alpine foreland.

Short summary
Glacio-lacustrine sediments from the overdeepened lower Salzach Valley were investigated. A 30 m long core retrieved sediments that could be identified as the “Salzburger Seeton”. Single-grain luminescence dating methods were applied on six samples spread over the whole depth of the core. The depositional age of these sediments was calculated to be 18.6 ± 0.9 ka. This time frame suggests that at least some shallow parts were filled by post-LGM (Last Glacial Maximum) lacustrine fine sediments.

Glacier reconstructions provide insights into past climatic conditions and elucidate processes and feedbacks that modulate the climate system both in the past and present. We investigate the transition from the last glacial to the current interglacial and generate beryllium-10 moraine chronologies in glaciated catchments of the eastern European Alps. We find that rapid warming was superimposed by centennial-scale cold phases that appear to have influenced large parts of the Northern Hemisphere.

Short summary
The Last Glacial Maximum (LGM) about 21 kyr ago is known to have been global in extent. Nonetheless, we have limited knowledge during the pre-LGM time in the southern middle latitudes. If we want to understand the causes of the ice ages, the complete glacial period must be addressed. In this paper, we show that the Patagonian Ice Sheet in southern South America reached its full glacial extent also by 57 kyr ago and defies a climate explanation.

Short summary
We investigated the geomorphological and geological characteristics of the archaeological sites Hawelti–Melazo and the surroundings. We performed sedimentological analyses, as well as direct (luminescence) and indirect (radiocarbon) sediment dating, to reconstruct the palaeoenvironmental conditions, which we integrated into the wider context of Tigray.
We investigated the geomorphological and geological characteristics of the archaeological sites...
