Challenges To Select Suitable Habitats And Demonstrate ‘Additionality’ In Blue Carbon Projects: A Seagrass Case Study, Anna Lafratta, Oscar Serrano, Pere Masqué, Miguel A. Mateo, Milena Fernandes, Sam Gaylard, Paul S. Lavery

Research outputs 2014 to 2021

© 2020 Elsevier Ltd Seagrass restoration has been suggested as a Blue Carbon (BC) strategy for climate change mitigation. For Nationally Determined Contributions (NDC) and carbon crediting schemes, BC projects need to demonstrate ‘additionality’, that is enhanced CO2 sequestration and/or avoided greenhouse gas emissions following management actions. This typically requires determining soil carbon accumulation rates (CAR), which is often done using radionuclides or surface elevation tables to estimate sedimentation rates. Here we undertook a case study, using 210Pb and 14C dating, to detect possible changes in Corg stocks and CAR following the loss and partial recovery of Posidonia seagrass meadows …

Assessment Of Soil Protein And Refractory Soil Organic Matter Across Two Chronosequences Of Newly Developing Marshes In Coastal Louisiana, Usa, Stuart Alexander Mcclellan

LSU Doctoral Dissertations

The impacts of sea-level rise and hydrologic manipulation are threatening the stability of coastal marshes throughout the world, thereby increasing the potential for re-mineralization of soil organic matter (SOM) in these systems. Such threats have prompted marsh restoration efforts, particularly in coastal Louisiana, yet it is unclear how the slowly decomposing (refractory) and quickly decomposing (labile) fractions of SOM may be differentially affected by different approaches to marsh restoration. Additionally, otherwise labile compounds may accumulate in the soil via a range of protective mechanisms, including rapid burial and association with organic compounds that are thought to enhance soil aggregation, such …

Factors Influencing Carbon Stocks And Accumulation Rates In Eelgrass Meadows Across New England, Usa, A. B. Novak, M. C. Pelletier, P. Colarusso, J. Simpson, M. N. Gutierrez, A. Arias-Ortiz, M. Charpentier, Pere Masque, P. Vella

Research outputs 2014 to 2021

Increasing the protection of coastal vegetated ecosystems has been suggested as one strategy to compensate for increasing carbon dioxide (CO2) in the atmosphere as the capacity of these habitats to sequester and store carbon exceeds that of terrestrial habitats. Seagrasses are a group of foundation species that grow in shallow coastal and estuarine systems and have an exceptional ability to sequester and store large quantities of carbon in biomass and, particularly, in sediments. However, carbon stocks (Corg stocks) and carbon accumulation rates (Corg accumulation) in seagrass meadows are highly variable both spatially and temporally, making it difficult to extrapolate this …

Impact Of Seagrass Establishment, Industrialization And Coastal Infrastructure On Seagrass Biogeochemical Sinks [Dataset], Oscar Serrano, Paul Lavery, James Bongiovanni, Carlos Duarte

Research Datasets

The database compiles published data (in Serrano et al. 2020, Marine Environmental Research, in press) on biogeochemical characteristics (density, organic carbon, stable carbon isotopes, chemical element and sediment grain size) of cores from Posidonia sinuosa soil in Cockburn Sound, Western Australia. Pb-210 concentrations of the first 20 cm are included along with C-14 raw ages.

Duarte, Anna Lafratta, Catherine E. Lovelock, Peter I. Macreadie, Jimena Samper-Villarreal, Cristian Salinas, Christian Sanders, Stacey Trevathan-Tackett, Mary Young, Andy Steven, Oscar Serrano

Research Datasets

This database contains data on top 30 cm soil biogeochemical properties from soil cores (minimum length of 30 cm) sampled in seagrass (n=201 cores) and adjacent unvegetated patches (n=39) around Australia.

Average biogeochemical properties per core along with information about type of environment, biotic characteristics and environmental conditions.

In particular, the variables included in sheet 1 are:

- Core ID (column A): core code

- Location (column B): name of the region of the sampling site.

- Latitude / Longitude (columns C, D): latitude and longitude

- Bioregion (column E): classified the sampling sites according to …

Ecosystem Services And Disservices Of Mangrove Forests And Salt Marshes, Daniel A. Friess, Erik S. Yando, Jahson B. Alemu I, Lynn-Wei Wong, Sasha D. Soto, Natasha Bhatia, S. J. Hawkins (Ed.), A. L.

Coastal wetlands such as mangrove forests and salt marshes provide a range of important benefits to people, broadly defined as ecosystem services. These include provisioning services such as fuelwood and food, regulating services such as carbon sequestration and wave attenuation, and various tangible and intangible cultural services. However, strong negative perceptions of coastal wetlands also exist, often driven by the perceived or actual ecosystem disservices that they also produce. These can include odour, a sense of danger, and their real or perceived role in vector and disease transmission (e.g. malaria). This review provides an introduction to the ecosystem services and …
