      Coastal Blue Carbon Program Learn the Basics. Blue carbon is the ability of tidal wetlands and seagrass habitats to capture and store carbon dioxide and other greenhouse gases from the atmosphere, helping to mitigate the effects of climate change. Graham J. Davis has written: 'Organic carbon and deoxygenation in the Pamlico River Estuary' -- subject(s): Carbon cycle (Biogeochemistry), Estuarine ecology Asked in Books and Literature.

      degassing suggests that much of the terrestrial organic car-bon, including that from coastal wetlands, is respired to CO2 during transport through the estuarine zone, though the rel-ative importance of river-supplied CO2 and organic carbon versus those from the coastal wetlands is debatable (Borges and Abril, ; Cai, ). Multiple techniques, including thermal infrared aerial remote sensing, geophysical and geological data, geochemical characterization and radium isotopes, were used to evaluate the role of groundwater as a source of dissolved nutrients, carbon, and trace gases to the Okatee River estuary, South Carolina. Thermal infrared aerial remote sensing surveys illustrated the presence of multiple.

      A numerical simulation of circulation in the Columbia River estuary and plume during the summer of is used to explore the mixing involved as river water is transformed into shelf water. The model is forced with realistic river flow, tides, wind stress, surface heat flux, and ocean boundary conditions.   Deoxygenation also affects major nutrients and carbon in the oceans. There are already several known dead zones — where oxygen levels are at zero — and low-oxygen areas in the oceans. But new research published in Science by Denise Breitburg et al at the Smithsonian Environmental Research Center casts new light on this issue with some.

Get this from a library. Organic carbon and deoxygenation in the Pamlico River Estuary. [Graham J Davis; Mark M Brinson; William A Burke]. The classical outwelling hypothesis states that small coastal embayments (e.g. estuaries, wetlands) export their excess production to inshore marine waters. In line with this notion, the present study tested whether the Swartkops estuary acts as source or sink for carbon.

To this end, concentrations of dissolved inorganic carbon (DIC), dissolved organic carbon (DOC) and particulate organic Cited by: The Pamlico / ˈ p æ m l ɪ k oʊ / River is a tidal river that flows into Pamlico Sound, in North Carolina in the United States.

It is formed by the confluence of the Tar River and Tranters Creek. The historic Tuscarora tribe, an Iroquoian-language group originally from western New York, had been well established in North Carolina, including along the Pamlico River, before European contact.

Dissolved organic carbon (DOC) is one of the largest pools of reactive carbon in the world's oceans (Hedges et al., ).A better understanding of oceanic DOC dynamics as well as biogeochemical processes within and DOC transport through estuaries and coastal seas is essential to better constrain global carbon models Bauer and Druffel,Cauwet et al., Cited by: This organic carbon must be directly or indirectly the main source of fish's food because primary production within the estuary was low as compared with both river and plume area (CAD~E, ).

Although most BC is deposited near the site of production, long-range transport of BC through rivers and the atmosphere is possible.

The sources and sinks (point and non-point) of dissolved organic carbon (DOC), particulate organic carbon (POC) and dissolved inorganic carbon (DIC) are identified for the purposes of simulating.
