While it is well known that forests store large amounts of carbon from greenhouse gases (including carbon dioxide, nitrous oxide, and methane), research indicates that coastal wetlands might capture and store carbon at rates three to five times greater than forests.

Exchange Rates for Carbon, Nitrogen, and Phosphorus in Nueces and San Antonio Bay Marshes [Armstrong, Neal A.] on *FREE* shipping on qualifying offers.

Exchange Rates for Carbon, Nitrogen, and Phosphorus in Nueces and San Antonio Bay MarshesAuthor: Neal A. Armstrong.

Seasonal changes in exchange rates were plotted and discussed. The exchange rates for carbon, nitrogen, and phosphorus for the major plant types were found to be very similar to exchange rates measured previously for similar plant types in Lavaca, Nueces, and San Antonio Bays and the Trinity River delta.

Non-point Source Pollution Assessment of the San Antonio - Nueces Coastal Basin By David R.

Maidment and William K. Saunders Abstract The amount of pollution from non-point sources flowing in the streams of the San Antonio - Nueces coastal basin in South Texas is estimated by a GIS-based met hod using rainfall, runoff and land use data. The stable isotopes of sulfur, nitrogen, and carbon were used to trace organic matter flow in salt marshes and estuarine waters at Sapelo Island, Georgia.

Organic matter inputs from terrestrial sources as detrital input either from forests adjacent to the marshes or from rivers were not detectable by their isotopic signatures in estuarine Cited by: Carbon, nitrogen and phosphorus storage in subtropical seagrass meadows: examples from Florida Bay and Shark Bay James W.

Coastal salt marshes play an important role in maintaining the balance of atmospheric carbon dioxide and serve as carbon sink with an estimated carbon burial rate of g C/m 2 /yr 1.Unlike most Cited by: extensive in Suisun Bay in the northern section of the estu-ary (Fig.

Brackish marshes are floristically distinctive and contain a greater diversity of plant species than either the salt marshes of San Francisco Bay or the freshwater marshes of the Sacramento–San Joaquin Delta (Atwateret al., ).

Part II: This volume contains all hydrographic, nutrient and chlorophyll data collected at discrete sampling depths during in San Antonio Bay and in Nueces/Corpus Christi Bay.

Water samples were normally collected just under the surface by hand and approximately 4 inches above the bottom by a horizontal water sampling by: 3. Nitrogen fixation rates did not consistently vary between natural and restored marshes within a site (Fossei Est, Tezze Fonde, Cenesa) but were negatively related to assayed plant biomass within the acetylene reduction samples collected among all marshes.

Highest nitrogen fixation rates were found at Tezze Fonde, the location closest to the. In coastal ecosystems, C org is called blue carbon, with recent global stock estimates ranging from to Mg C ha −1 (CEC, ), and total sequestration rates exceeding Tg.

Amos. Carbon consumption and nitrogen requirements were estimated for populations of the sandy beach bivalve Donax serra on nine beaches of the west coast of South Africa.

Subtidal populations composed mainly of adult clams were responsible for the bulk of standing stock ( g C m−1), annual carbon consumption (13 g C m−1 yr−1), faeces production ( g C Cited by: For both nitrogen and carbon, higher concentrations were found in the soil surface layers.

Higher soil nitrogen and carbon levels were associated with higher organic matter contents. Most of the nitrogen in the salt marsh occurred in the sediments (0–40 cm) and only ca. –% of the total was found in the by: Corpus Christi Bay is a large saltwater estuary at the mouth of the Nueces River (at 27°46' N, 97°15' W).

It is protected from the waves and storms of the Gulf of Mexico by Mustang Island. The bay is entirely in the jurisdiction of Nueces County, though its northern shoreline is the boundary of San Patricio County.

organic matter and nitrogen with varying success in SFE. Stable nitrogen isotopes were used to demonstrate that groundwater was the primary source of nitrate to the San Joaquin River (Kratzer et al. Stable carbon isotopes were used to trace the source of particulate and dissolved inorganic carbon along the salinity gradient from the Sacra.

Nueces Bay primarily drains the Nueces River Basin, but also drains adjacent portions of the San Antonio–Nueces Coastal Basin to the north and the Nueces Rio Grande Coastal Basin to the south. For this TMDL, the watershed has been delineated as depicted in Figure 2. Runoff from the drainage area upstream of Lake Corpus Christi (Segment ).

Estuaries are among the most productive habitats on the planet. Bacteria in estuary sediments control the turnover of organic carbon and the cycling of nitrogen and sulfur. These communities are complex and primarily made up of uncultured lineages, thus little is known about how ecological and metabolic processes are partitioned in sediments.

De novo Cited by: Introduction. Salt marshes are one of the most powerful carbon (C) sinks on the planet. They bury at a rate ~55 times faster than tropical rainforests (regarded as one of the most significant terrestrial C sinks), and their global carbon burial (up to ± Tg C yr-1 based on preliminary assessments) appears to exceed that of tropical rainforests (53 ± Tg C yr-1).Cited by: Stable carbon and nitrogen isotope composition of aquatic and terrestrial plants of the San Francisco Bay estuarine system James E.

Rates of carbon accumulation vary from the upper to the outer Bay, over which there is a gradient of decreasing tidal range and suspended sediment supply.

In the outer bay, high‐marsh densities are highest ( ± g C cm −3), but carbon accumulation rates over the past 30 years are lowest (76 g C m −2 yr −1).Cited by: carbon storage processes, reducing carbon storage rates to TgC/yr, a – percent change over baseline conditions.

In contrast, inorganic nitrogen (ammonium, nitrate). Soils from Shark Bay had, on average, 21% higher organic carbon content and 35% higher phosphorus content than Florida Bay.
