Abstract. Greenhouse gas (GHG) emissions from rivers are globally relevant, but quantification of these comes with considerable uncertainty. Quantification ecosystem-scale is challenged by both spatial and short-term temporal variability. We measured spatio-temporal variability CO2 CH4 fluxes a 1 km long reach the lowland river Elbe in Germany over 3 d to establish which factor more relevant be taken into consideration: small-scale or fluxes. GHG studied were dominated CO2, 90 % total water...
Rivers are significant sources of greenhouse gases (GHGs; e.g., CH 4 and CO 2 ); however, our understanding the large-scale longitudinal patterns GHG emissions from rivers remains incomplete, representing a major challenge in upscaling. Local hotspots moderate heterogeneities may be overlooked by conventional sampling schemes. In August 2020 for first time, we performed continuous (once per minute) measurements surface water during 584-km-long river cruise along German Elbe to explore...
Remote sensing (RS) enables a cost-effective, extensive, continuous and standardized monitoring of traits trait variations geomorphology its processes, from the local to continental scale. To implement better understand RS techniques spectral indicators derived them in geomorphology, this paper presents new perspective for definition recording five characteristics geomorphodiversity with RS, namely: geomorphic genesis diversity, structural taxonomic functional diversity. In respect,...
Design thinking is an approach typically used in product innovation and marketing that puts empathy for the end-user at centre of design process. a human-centred process emphasizes creativity collaboration, leading to facilitation citizen engagement through improved recruitment retention participants. Here we present two case studies use methodologies better understand scientists involved.CityCLIM (a European Union Horizon 2020 funded project) applied stakeholder analysis technique called...
Nutrient and carbon dynamics within the river-estuary-coastal water systems are key processes in understanding flux of matter from terrestrial environment to ocean. Here, we analysed those by following a sampling approach based on travel time an advanced calculation nutrient fluxes tidal part. We started with nearly Lagrangian river (River Elbe, Germany; 580 km 8 days). After subsequent investigation estuary, followed plume raster German Bight (North Sea) using three ships simultaneously. In...
Understanding the motivations and benefits of citizen science (CS) participants is critical to success environmental projects that rely on data collection from engaged citizens. Tailored communication with scientists essential, leading need target specific societal groups for extensive high-quality sets. The purpose study was apply marketing concepts such as stakeholder analysis, value proposition canvas (VPC), key performance indicators (KPIs) CS projects. examined extent which these...
A thorough and reliable assessment of changes in sea surface water temperatures (SSWTs) is essential for understanding the effects global warming on long-term trends marine ecosystems their communities. The first temperature measurements were established almost a century ago, especially coastal areas, some them are still operation. However, while earlier times these done by hand every day, current environmental observation stations (ELTOS) often fully automated integrated cabled underwater...
Recent discussions in many scientific disciplines stress the necessity of “FAIR” data. FAIR data, however, does not necessarily include information on data trustworthiness, where trustworthiness comprises reliability, validity and provenience/provenance. This opens up risk misinterpreting even though all criteria are fulfilled. Especially applications such as secondary processing, blending, joint interpretation or visualization efforts affected. paper intends to start a discussion community...
Abstract Heavy Precipitation Events (HPE) are the result of enormous quantities water vapor being transported to a limited area. HPE rainfall rates and volumes cannot be fully stored on below land surface, often leading floods with short forecast lead times that may cause damage humans, properties, infrastructure. Toward an improved scientific understanding entire process chain from formation flooding at catchment scale, we propose elaborated event-triggered observation concept. It combines...
Seismic borehole tomography with standard seismic sources and receivers provides higher-resolution results compared to alternative conventional surveys. The development of distributed acoustic sensing (DAS) for surveys offers practical advantages over sensors, such as higher spatial resolution, repeatable measurements, time savings. This study details the use DAS in conjunction at Svelvik CO 2 Field Lab conduct P-, SH-, SV-wave crosswell surveys, comparing data obtained from helically wound...

Marketing tools such as stakeholder analysis Value Proposition Canvas (VPC) are recognised valuable CS. Similar customer-focused approach business context, these able improve efficiency,...
Seismic shear waves primarily provide information on the stiffness and elastic properties of soil, rather than directly indicating soil stress history state over-consolidation. However, depending different static states a SH- SV-waves have individual site specific velocities can be used to evaluate dimensions over-consolidation at rest lateral conditions. A cross-hole experiment was carried out measure paired wave velocity profiles (SH SV) which allows determination geotechnical parameters...
<title>Abstract</title> Global warming affects the Earth system in complex ways, often preventing a functional understanding of underlying processes. Disentangling these processes between abiotic drivers and single species or entire communities is, however, essential for an in-depth climate change impacts on ecosystem.

The use of near-surface geothermal energy implying infrastructure increases significantly in Germany [1]. Therefore it becomes an essential subject for impact analysis our groundwater resource. Rock physical properties change through the alteration pore fluid such as temperature. Those alterations happen under influence heat subsurface. Variations geophysical proxies can provide information about subsurface changes. Laboratory measurements by Jaya et al. [2] show that P-wave velocities...
