Scotland’s blue carbon: the contribution from seaweed detritus
… more prominent. Introduction of the term ‘blue carbon’ (BC) has drawn attention to natural coastal habitats and their capacity to fix CO2. The overall aim of this thesis was to place the importance of carbon sequestration within the already essential services that macroalgae provide to the …

Spatial analysis of blue carbon in a UK Saltmarsh: Implications of carbon distribution.
… have been found to be significant stores of blue carbon with important links to the global carbon cycle. Saltmarshes have the ability to sequester a significant amount of carbon with long residence times once buried. In this investigation, the spatial distribution of organic carbon of …

Seagrass Carbon Standing Stock in the Northern Gulf of Mexico: The Role of Seagrass Beds in Mississippi as Potential Blue Carbon Sinks
<p>Organic carbon stored in marine ecosystems is known as blue carbon. Seagrass beds have the ability to contribute to global blue carbon standing stocks through the uptake and sequestration of carbon from the water column. Through coastal management and conservation best practices, blue carbon …

Carbon dynamics in coastal vegetated communities: evaluation of anthropogenic impacts, chemical characterization of dissolved organic matter, and its influence on blue carbon sequestration
… was the possibility of capturing and removing carbon through natural ecosystems. In this context, coastal vegetated communities have been noted for their fundamental role in sequestering and storing carbon in the sediment (blue carbon), incorporating carbon dioxide (CO2) and removing it from …

Three essays on environmental valuation: the social value of carbon storage in wetlands, the impact of wind turbines on home prices, and the effect of flood risk on home prices
… aspect of climate change, from the value of a blue carbon sink, the impact of renewable energy technology on property prices, and the effect of changing flood risk and coastal amenities on property prices. ☐ The first essay in this work looks at valuing changes in the economic value of carbon …

Carbon storage and preservation in seagrass meadows
Seagrass meadows are important ‘Blue Carbon’ sinks but many questions remain unaddressed in regards to the organic carbon (OC) sequestration capacity and processes leading to retention and persistence of OC in seagrass sediments. The research summarised in this dissertation examined 37 sediment …

Análise do potencial do sequestro e estoque de carbono em diferentes cenários de manejo pelos manguezais da região metropolitana da Baixada Santista do Litoral Paulista
… eficientes na captura e armazenamento de carbono desempenhando papel fundamental na mitigação das mudanças climáticas. No entanto, a intensificação das atividades humanas e os efeitos do aquecimento global têm comprometido sua integridade e funcionalidade desse ecossistema. Este estudo …

Impact Assessment of Natural Resource Management Policy Research: A case study of the contribution of the Sustainable Wetlands Adaptation and Mitigation Project to the effectiveness of the Indonesian Forest Moratorium
… avoid the release of 10 - 20 million tons of carbon dioxide over the next 15 years, which corresponds to a mean social value of $402 - 805 million using a $40/ton social cost of carbon. With SWAMP's timely knowledge generation on tropical wetland carbon dynamics we estimate that $4.03 - 40.26 …

Spatial and temporal variability of carbon stocks within the River Colne Estuary
Saltmarshes are one of the most significant blue carbon sinks but there is a paucity of information regarding saltmarsh carbon stocks globally, consequently these habitats are not included in the global carbon budget. The aim of this study is therefore to better understand the spatial and temporal …

Capturing dynamics of marine inorganic carbon fluxes from diurnal to decadal timescales
The marine carbon cycle plays an important role in regulating Earth’s climate. The vastness of the open ocean and the large variability in the coastal ocean provide obstacles to accurately quantify storage and transport of inorganic carbon within marine ecosystems and between marine and other earth …

Intertidal Seagrass Meadows in South West England: The Ecology of Expansion
… the spatio-temporal variability of the organic carbon (Corg) stocks through analysis of sediment cores, and the biodiversity of the macrobenthic assemblage within these new meadows through infauna cores, comparing results with samples collected from an established Zostera noltii meadow within …

Carbon and nitrogen cycling in vegetated coastal ecosystems
… play a disproportionate role in greenhouse gas (carbon dioxide (CO2), methane (CH4), and nitrous oxide (N2O)) and nutrient cycling. Vegetated coastal ecosystems (e.g., mangroves, salt marshes, and seagrasses) are key drivers of coastal greenhouse gas and nutrient cycling because of their …

The influence of hydrodynamics on the growth, erosion and biomechanical properties of Laminaria digitata
… macroalgae may be significant contributors to blue carbon as it is estimated that ~90% of carbon fixed by macroalgae is transported by water motion and sequestered in coastal or offshore sediments. Macroalgae such as the kelp Laminaria digitata are found in temperate waters growing in the low …

Electrochemical Tape-and-Paper-Based Sensor for the Quantification of Potassium
… home-use. Our sensing method relies on Prussian blue immobilized on the surface of electrodes as a potassium recognition element. Potassium ions intercalate into the Prussian blue lattice and subsequently changes the electrochemical characteristics of Prussian blue such as the redox peak …

Physiological effects of climate change and estimations of carbon standing stock of southern Salish Sea kelps
… and acidification. Finally, we quantified kelp carbon standing stock across four bull kelp beds in the Salish Sea. The degree to which kelp sequester carbon remains highly debated; before kelp can be included in blue carbon accounting, accurate estimates of carbon standing stock are needed. The …
