Hypoxia, a growing worldwide problem, has been intermittently present in the modern Baltic
Sea since its formation ca. 8000 cal. yr BP. However, both the spatial extent and intensity of …

Methane (CH 4 ) is produced in many natural systems that are vulnerable to change under a
warming climate, yet current CH 4 budgets, as well as future shifts in CH 4 emissions, have …

Human habitation may significantly affect the chemical soil composition leading to enrichments
and depletions of specific chemical elements and the formation of archaeological soils. …

Nutrient input through submarine groundwater discharge (SGD) rivals river inputs in certain
regions and may play a significant role in nutrient cycling and primary productivity in the …

The exchange of CO 2 between the atmosphere and the global coastal ocean was evaluated
from a compilation of air‐water CO 2 fluxes scaled using a spatially‐explicit global typology …

Iron oxides affect many elemental cycles in aquatic sediments via numerous redox reactions
and their large sorption capacities for phosphate and trace elements. The reactive ferric …

Human activities, especially increased nutrient loads that set in motion a cascading chain of
events related to eutrophication, accelerate development of hypoxia (lower oxygen …

Differential X-ray powder diffraction (DXRD) and extraction procedures were used to
characterize the iron oxides present in four sediments from contrasting environments in the North …
