Environmental factors influencing benthic communities in the oxygen minimum zones on the Angolan and Namibian margins [PDF]
Thriving benthic communities were observed in the oxygen minimum zones along the southwestern African margin. On the Namibian margin, fossil cold-water coral mounds were overgrown by sponges and bryozoans, while the Angolan margin was characterized by ...

The water column distribution of carbonate system variables at the ESTOC site from 1995 to 2004 [PDF]
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]
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]
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]
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]
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]
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]
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]
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 ...
