Vessel-generated waves and currents significantly impact coastal and estuarine waterways. In-situ measurements record all relevant physical phenomena that occur under a wide range of conditions and are therefore a valuable resource in the investigation of ship waves. Here we present a comprehensive compound dataset from in-situ ship wave measurement campaigns conducted over several decades in German coastal waterways. The dataset includes measured ship waves heights and currents as well as an attribution of each wave event to ship and nautical parameters responsible for its generation. The dataset is unique in its scope, combining a significant number of data points from multiple sites with different cross-section profiles. Some campaigns feature multiple gauges per cross-section, facilitating the analysis of wave transformation processes. Some locations feature repeat measurements which helps to understand wave load histories due to e.g. changes in shipping fleet structures and navigation practices. This dataset aims to provide a basis to enhance data-driven models to predict and manage the impacts of vessel-generated waves in different topographic settings and fleet structures.

Relic munitions from warfare and intentional dumping contaminate coastal waters worldwide, with an estimated 300,000 tons in the German Baltic Sea alone. These contain toxic conventional explosive chemicals, including 2,4,6-trinitrotoluene (TNT), 1,3,5-trinitro-1,3,5-triazinane (RDX), and 1,3-dinitrobenzene (DNB). Corrosion of metal munition housings in seawater releases these munition chemicals (MCs) to the marine environment.

One group of elements attracting more and more attention are so-called technology-critical elements (TCEs). In comparison with legacy pollutants, the anthropogenic impact of TCEs on the environment might still be minor, but various applications introduce them to the most remote places in the world including the marine environment. One area prone to pollution is the Baltic Sea, partly due to the lack of water exchange with the North Sea.

The amount of methane released to the atmosphere from the Nord Stream subsea pipeline leaks remains uncertain, as reflected in a wide range of estimates. A lack of information regarding the temporal variation in atmospheric emissions has made it challenging to reconcile pipeline volumetric (bottom-up) estimates with measurement-based (top-down) estimates. Here we simulate pipeline rupture emission rates and integrate these with methane dissolution and sea-surface outgassing estimates to model the evolution of atmospheric emissions from the leaks.

The first Neolithic farmers arrived in the Western Mediterranean area from the East. They established settlements in coastal areas and over time migrated to new environments, adapting to changing ecological and climatic conditions. While farming practices and settlements in the Western Mediterranean differ greatly from those known in the Eastern Mediterranean and central Europe, the extent to which these differences are connected to the local environment and climate is unclear.
