TL;DR: A global database of bioturbation rates and patterns is assembled and it is clear that the role of benthic invertebrates in mediating global ecosystem processes is substantial, but the level of uncertainty at the regional level is unacceptably high for much of the globe.

TL;DR: In this paper, high-frequency observations from instrumented moorings deployed in the central North Sea, at Oyster Grounds and on the northern slope of Dogger Bank (North Dogger), revealed the variable nature of summer oxygen depletion at the Oyster grounds.

TL;DR: Biogeochemical processes in the upper layers of sediment, both oxic and suboxic, seemed unaffected by trawling in the long- term, but in deeper anoxic sediment, mineralisation via sulphate reduction may be stimulated by the extra disturbance, at least in areas where tidal energy is slight.

TL;DR: The marine ecosystem response to climate change and demersal trawling was investigated using the coupled hydrodynamic-biogeochemical water column model GOTM-ERSEM-BFM for three contrasting sites in the North Sea as mentioned in this paper.

TL;DR: In this paper, a hydrodynamic model is developed for the Blackwater estuary (UK) and used to estimate nitrate removal by denitrification, and the analysis reveals that carbon and nutrient storage plus habitat creation represent major and quantifiable benefits of realignment.
