Ongoing acidification of the ocean through uptake of anthropogenic CO2 is known to affect marine biota and ecosystems with largely unknown consequences for marine food webs. Changes in food web structure have the potential to alter trophic transfer,

Influence of Ocean Acidification on a Natural Winter-to-Summer Plankton Succession: First Insights from a Long-Term Mesocosm Study Draw Attention to Periods of Low Nutrient Concentrations.

Publikováno v: PLoS ONE, Vol 11, Iss 8, p e0159068 (2016)

Every year, the oceans absorb about 30% of anthropogenic carbon dioxide (CO2) leading to a re-equilibration of the marine carbonate system and decreasing seawater pH. Today, there is increasing awareness that these changes-summarized by the term ocea

Publikováno v: Biogeosciences. 13:3035-3050

Studies investigating the effect of increasing CO2 levels on the phosphorus cycle in natural waters are lacking although phosphorus often controls phytoplankton development in many aquatic systems. The aim of our study was to analyse effects of eleva

Sediment traps are the most common tool to investigate vertical particle flux in the marine realm. However, the spatial and temporal decoupling between particle formation in the surface ocean and particle collection in sediment traps at depth often h

Effect of elevated CO2 on organic matter pools and fluxes in a summer Baltic Sea plankton community

Autor: Tim Boxhammer, Yves Trense, Lennart T. Bach, Eric P. Achterberg, Ulf Riebesell, Dana Hellemann, Jan Czerny, Allanah J. Paul, Kai G. Schulz, Monika Nausch, Michael Sswat

Publikováno v: Biogeosciences. 12:6181-6203

Ocean acidification is expected to influence plankton community structure and biogeochemical element cycles. To date, the response of plankton communities to elevated CO2 has been studied primarily during nutrient-stimulated blooms. In this CO2 manip

Anthropogenic emissions of carbon dioxide (CO2) and the ongoing accumulation in the surface ocean together with concomitantly decreasing pH and calcium carbonate saturation states have the potential to impact phytoplankton community composition and t

Competitive fitness of a predominant pelagic calcifier impaired by ocean acidification

Autor: Lennart T. Bach, Richard G. J. Bellerby, Aud Larsen, Kai G. Schulz, J. Rafael Bermúdez Monsalve, Jan Czerny, Andrea Ludwig, Tim Boxhammer, Ulf Riebesell

Publikováno v: Nature Geoscience, 10 . pp. 19-23.

Coccolithophores—single-celled calcifying phytoplankton—are an important group of marine primary producers and the dominant builders of calcium carbonate globally. Coccolithophores form extensive blooms and increase the density and sinking speed

Implications of elevated CO2 on pelagic carbon fluxes in an Arctic mesocosm study – an elemental mass balance approach

Recent studies on the impacts of ocean acidification on pelagic communities have identified changes in carbon to nutrient dynamics with related shifts in elemental stoichiometry. In principle, mesocosm experiments provide the opportunity of determini

The volume of water enclosed inside flexible-wall mesocosm bags is hard to estimate using geometrical calculations and can be strongly variable among bags of the same dimensions. Here we present a method for precise water volume determination in meso
