  • The damming of rivers has large impacts on the balance of riverine carbon (C) processes and fluxes to the oceans. Here, the authors use decadal riverine organic C loads and model C transformations to quantify in-reservoir organic C burial, mineralization and assess decreases in riverine exports to the oceans.

  • The authors show that estuarine and coastal vegetation are collectively a greenhouse gas (GHG) sink for the atmosphere, but methane and nitrous oxide emissions counteract the carbon dioxide uptake. Critical coastal GHG sink hotspots are identified in Southeast Asia, North America and Africa.

  • Continental shelves have become a substantial sink of anthropogenic mercury since the onset of the Industrial Revolution. However, human activities and climate-related processes can remobilize mercury-bearing sediment, potentially transforming this mercury sink into a marine source.

  • Bottom-up and top-down approaches are used to quantify global nitrous oxide sources and sinks resulting from both natural and anthropogenic sources, revealing a 30% increase in global human-induced emissions between 1980 and 2016.

  • River damming can harness hydropower, control flooding and store water, but can also alter biogeochemistry in reservoirs and downstream environments. In this Review, the impacts of dams on nutrient cycling and greenhouse production are discussed, emphasizing the need to consider biogeochemical cycling at all stages of dam lifespan.

  • Rivers transport about 1,000 Mg mercury annually to coastal oceans, which is threefold greater than the amount delivered by atmospheric deposition, according to a global analysis of mercury measurements in rivers.

  • A review of current river ecosystem metabolism research quantifies the organic and inorganic carbon flux from land to global rivers and demonstrates that the carbon balance can be influenced by a changing world.
