Export of dissolved organic carbon from peatlands under elevated carbon dioxide levels

Nature, 2004
Peatlands represent a vast store of global carbon. Observations of rapidly rising dissolved organic carbon concentrations in rivers draining peatlands have created concerns that those stores are beginning to destabilize. Three main factors have been put forward as potential causal mechanisms, but it appears that two alternatives--warming and increased ...

Antarctic krill vertical migrations modulate seasonal carbon export

Science
Vertical migrations by marine organisms contribute to carbon export by consumption of surface phytoplankton followed by defecation in the deep ocean. However, biogeochemical models lack observational data, leading to oversimplified representation of carbon cycling by migrating organisms, such as Antarctic krill ( Euphausia ...

EXPORTS OF ORGANIC CARBON IN BRITISH RIVERS

Hydrological Processes, 1997
This study provides the first detailed estimate of riverine organic carbon fluxes in British rivers, as well as highlighting major gaps in organic carbon data in national archives. Existing data on organic carbon and suspended solids concentrations collected between 1989 and 1993, during routine monitoring by the River Purification Boards (RPBs) in ...

Coccolithovirus facilitation of carbon export in the North Atlantic

Nature Microbiology, 2018
Marine phytoplankton account for approximately half of global primary productivity 1 , making their fate an important driver of the marine carbon cycle. Viruses are thought to recycle more than one-quarter of oceanic photosynthetically fixed organic carbon 2 , which can stimulate nutrient regeneration, primary production and upper ocean respiration 2 ...

Carbon export from continental shelves, denitrification and atmospheric carbon dioxide

Continental Shelf Research, 1994
Abstract To investigate the long-term role of continental shelves, a global carbon ☐ model which included continental shelf waters and sediments, ocean surface waters, the deep-sea and the atmosphere was constructed. With nitrogen limiting oceanic primary production, the model included balanced nitrogen inputs (from the continents and atmosphere) and

Small Phytoplankton and Carbon Export from the Surface Ocean

Science, 2007
Autotrophic picoplankton dominate primary production over large oceanic regions but are believed to contribute relatively little to carbon export from surface layers. Using analyses of data from the equatorial Pacific Ocean and Arabian Sea, we show that the relative direct and indirect contribution of picoplankton to export is proportional to their ...

Exports And Imports Under A Carbon Tax

2009
Abstract One of the major challenges facing the world is how to deal with pollution. While local and regional pollution has been around since the beginning of civilized society, only in much more recent times have many nations needed to find jointly a means to tackle pollution.
