The water column distribution of carbonate system variables at the ESTOC site from 1995 to 2004 [PDF]
Biogeosciences, 2010 The accelerated rate of increase in atmospheric carbon dioxide and the substantial fraction of anthropogenic CO<sub>2</sub> emissions absorbed by the oceans are affecting the anthropocenic signatures of seawater.

Benthic biomass size spectra in shelf and deep-sea sediments [PDF]
Biogeosciences, 2014 The biomass distributions of marine benthic metazoans (meio- to macro-fauna, 1 μg–32 mg wet weight) across three contrasting sites were investigated to test the hypothesis that allometry can consistently explain observed trends in biomass spectra ...

Side effects and accounting aspects of hypothetical large-scale Southern Ocean iron fertilization [PDF]
Biogeosciences, 2010 Recent suggestions to slow down the increase in atmospheric carbon dioxide have included ocean fertilization by addition of the micronutrient iron to Southern Ocean surface waters, where a number of natural and artificial iron fertilization experiments ...

Environmental correlates of peatland carbon fluxes in a thawing landscape: do transitional thaw stages matter? [PDF]
Biogeosciences, 2015 Peatlands in discontinuous permafrost regions occur as a mosaic of wetland types, each with variable sensitivity to climate change. Permafrost thaw further increases the spatial heterogeneity in ecosystem structure and function in peatlands.

What was the source of the atmospheric CO2 increase during the Holocene? [PDF]
Biogeosciences, 2019 The atmospheric CO2 concentration increased by about 20 ppm from 6000 BCE to the pre-industrial period (1850 CE). Several hypotheses have been proposed to explain mechanisms of this CO2 growth based on either ocean or land carbon ...

Role of jellyfish in the plankton ecosystem revealed using a global ocean biogeochemical model [PDF]
Biogeosciences, 2021 Jellyfish are increasingly recognised as important components of the marine ecosystem, yet their specific role is poorly defined compared to that of other zooplankton groups.

Drivers and uncertainties of future global marine primary production in marine ecosystem models [PDF]
Biogeosciences, 2015 Past model studies have projected a global decrease in marine net primary production (NPP) over the 21st century, but these studies focused on the multi-model mean rather than on the large inter-model differences. Here, we analyze model-simulated changes

Permafrost coverage, watershed area and season control of dissolved carbon and major elements in western Siberian rivers [PDF]
Biogeosciences, 2015 Analysis of organic and inorganic carbon (DOC and DIC, respectively), pH, Na, K, Ca, Mg, Cl, SO4 and Si in ~ 100 large and small rivers (< 10 to ≤ 150 000 km2) of western Siberia sampled in winter, spring, and summer over a more than 1500 km ...

Variable particle size distributions reduce the sensitivity of global export flux to climate change [PDF]
Biogeosciences, 2021 Recent earth system models predict a 10 %–20 % decrease in particulate organic carbon export from the surface ocean by the end of the 21st century due to global climate change. This decline is mainly caused by increased stratification of the upper ocean,

Quantifying the impact of ocean acidification on our future climate [PDF]
Biogeosciences, 2014 Ocean acidification (OA) is the consequence of rising atmospheric CO2 levels, and it is occurring in conjunction with global warming. Observational studies show that OA will impact ocean biogeochemical cycles. Here, we use an Earth system model under the
