Metadata: A data product describing Carbon and nitrogen impacts of seaweed and mussel aquaculture estimated using life cycle impact assessment
Abstract:
Estimates of the global warming potential (GWP, carbon impact) and marine eutrophication potential (MEP, nitrogen impact) resulting from seaweed and mussel aquaculture. These data includes outputs on global warming potential (GWP, carbon impact, kg carbon dioxide equivalent) and marine eutrophication potential (MEP, nitrogen impact, kg nitrogen equivalent). Values for the mussel are given per 1 kg live weight. Values for seaweed are given per 1 million tonnes of wet-weight. These data were collected to understand the role that seaweed and bivalve aquaculture can play in achieving Net Zero and eutrophication remediation in England. The life cycle impact assessments (LCIAs) consider rope grown blue mussels (Mytilus edulis) and sugar kelp (Saccharina latissima) in English waters. Mussels are grown for food purposes, while seaweed is grown for production of biochar and biofuel. The data are given as summaries per component of the life cycle impact assessment as csvs, and the models themselves are exported to text files which can be used in SimaPro.

| Title | The title is used to provide a brief and precise description of the dataset such as 'Date', 'Originating organisation/programme', 'Location' and 'Type of survey'. All acronyms and abbreviations should be reproduced in full. | A data product describing Carbon and nitrogen impacts of seaweed and mussel aquaculture estimated using life cycle impact assessment |
| File Identifier | The File Identifier is a code, preferably a GUID, that is globally unique and remains with the same metadata record even if the record is edited or transferred between portals or tools. | CEFAS637a0a3d-6f49-446b-ba31-39b14a97182d |
| Resource Identifier | This is the code assigned by the data owner. | CEFAS22148 |
| Resource type | The resource type will likely be a dataset but could also be a series (collection of datasets with a common specification) or a service. | dataset |
| Start date | This describes the date the resource starts. This may only be the year if month and day are not known | 2022-04-01 |
| End date | This describes the date the resource ends. This may only be the year if month and day are not known | 2025-04-01 |
| Frequency of updates | This describes the frequency with which the resource is modified or updated i.e. a monitoring programme that samples once per year has a frequency that is described as 'annually'. | notPlanned |

| Lineage | Lineage includes the background information, history of the sources of data, data quality statements and methods. | The life cycle assessment (LCA) of both the seaweed and bivalve aquaculture was completed using SimaPro 9.5.0.0. Inputs used the ecoinvent 3.0 database. The life cycle inventories (LCIs) were compiled using a combination of published peer-reviewed literature and grey literature. For the life cycle impact assessment (LCIA) method, ReCiPe 2016 Midpoint (H) V1.08 was chosen, which is the default ReCiPe midpoint method. |
