Variability of the surface energy balance in permafrost-underlain boreal forest [PDF]

Biogeosciences, 2021
Boreal forests in permafrost regions make up around one-third of the global forest cover and are an essential component of regional and global climate patterns.

Carbon–nitrogen interactions in European forests and semi-natural vegetation – Part 1: Fluxes and budgets of carbon, nitrogen and greenhouse gases from ecosystem monitoring and modelling [PDF]

Biogeosciences, 2020
The impact of atmospheric reactive nitrogen (Nr) deposition on carbon (C) sequestration in soils and biomass of unfertilized, natural, semi-natural and forest ecosystems has been much debated.

Long-term trends at the Boknis Eck time series station (Baltic Sea), 1957–2013: does climate change counteract the decline in eutrophication? [PDF]

Biogeosciences, 2014
The Boknis Eck (BE) time series station, initiated in 1957, is one of the longest-operated time series stations worldwide. We present the first statistical evaluation of a data set of nine physical, chemical and biological parameters in the period ...

Quantifying the influence of CO₂ seasonality on future aragonite undersaturation onset [PDF]

Biogeosciences, 2015
Ocean acidification is a predictable consequence of rising atmospheric carbon dioxide (CO2), and is highly likely to impact the entire marine ecosystem – from plankton at the base of the food chain to fish at the top.

Bipolar carbon and hydrogen isotope constraints on the Holocene methane budget [PDF]

Biogeosciences, 2018
Atmospheric methane concentration shows a well-known decrease over the first half of the Holocene following the Northern Hemisphere summer insolation before it started to increase again to preindustrial values.

The Open Climate Campaign - why we need open access to climate science

, 2023
Climate change, and the resulting harm to our global biodiversity, is one of the world's most pressing challenges. While the existence of climate change and the resulting loss of biodiversity is certain, knowledge and data about these global challenges and the possible solutions, mitigations and actions to tackle them is too often not publicly ...

Investigating the effect of El Niño on nitrous oxide distribution in the eastern tropical South Pacific [PDF]

Biogeosciences, 2019
The open ocean is a major source of nitrous oxide (N2O), an atmospheric trace gas attributable to global warming and ozone depletion. Intense sea-to-air N2O fluxes occur in major oceanic upwelling regions such as the eastern tropical South Pacific (ETSP).

Constraints on global oceanic emissions of N₂O from observations and models [PDF]

Biogeosciences, 2018
We estimate the global ocean N2O flux to the atmosphere and its confidence interval using a statistical method based on model perturbation simulations and their fit to a database of ΔpN2O (n =  6136). We evaluate two submodels of N2O production.

Including high-frequency variability in coastal ocean acidification projections [PDF]

Biogeosciences, 2015
Assessing the impacts of anthropogenic ocean acidification requires knowledge of present-day and future environmental conditions. Here, we present a simple model for upwelling margins that projects anthropogenic acidification trajectories by combining ...

Quantifying impacts of the 2018 drought on European ecosystems in comparison to 2003 [PDF]

Biogeosciences, 2020
In recent decades, an increasing persistence of atmospheric circulation patterns has been observed. In the course of the associated long-lasting anticyclonic summer circulations, heatwaves and drought spells often coincide, leading to so-called hotter ...
