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.

Erosion processes below glacier ice have carved large and deep basins in the landscapes surrounding mountain ranges as well as polar regions. With our comparison, we show that these two groups of basins are very similar in their shapes and sizes. However, open questions still remain especially regarding the sediments that later fill up these basins. We aim to stimulate future research and promote exchange between researchers working around the Alps and the northern central European lowlands.

The loess sequence of Köndringen, Upper Rhine Graben, comprises several glacial–interglacial cycles. It has been investigated using a multi-method approach including the measurement of colour, grain size, organic matter, and carbonate content. The analyses reveal that the sequence comprises several fossil soils and layers of reworked soil material. According to luminescence dating, it reaches back more than 500 000 years.

We present an update on the distribution of tunnel valleys in the southeastern North Sea between Amrum and Heligoland based on active seismic data. Our results demonstrate that very dense grids of seismic profiles are needed to understand the distribution and the formation of tunnel valleys in a given region. We also demonstrate that acquiring offshore active seismic data is time- and cost-effective to learn more about the formation and filling of tunnel valleys in different geological settings.

The depositional sequences of all types of coastal sediments which accumulated during the Holocene sea-level rise along the NE German coast and in the inner coastal waters are comprehensively described and classified into four formations and two subformations. Their detailed characterisation and chronostratigraphic correlation are an important addition to the only brief definition given in the LithoLex database of the Federal Institute for Geosciences and Natural Resources (BGR).

In this contribution we highlight as an example the application of a freely available tool for the Google Earth Engine. The software allows cloud-free satellite images to be processed. We show processing examples for the Nile Delta (Egypt) and how the remote sensing images are used to find hints of buried landforms, such as former river branches of the Nile.
