Flux Of Fish Carbon To The Irish Sea Floor (1973-2016)

The data includes carbon fluxes from the Irish Sea EwE model simulation runs. These estimates come from outputs of Ecosim runs linked to offline equations to estimate carbon fluxes by the fish community. The Irish Sea EwE is a peer-reviewed food web model of the Irish Sea developed by Bentley et al. (2019). We used the Irish Sea EwE model and past data (1973- 2016) to simulate two fishing scenarios and used the outputs of Ecosim with offline equations to estimate fish C flux to the seafloor in a continental shelf region. The results quantify carbon flux from the fish community in fish faecal pellets and carcasses. The attenuation of faecal pellets in the water column is accounted for in the calculations. Two scenarios were assessed: the past fishing scenario, as used in the Irish Sea EwE key run and a scenario with no fishing. Irish Sea carbon flux is measured in mgC m -2d -1.  Data is available in .csv format and contains the following variables:  "Year", "Cflux" (Total fish-mediated carbon flux to the seafloor in the reported fishing scenario), "Cflux_nofishing" (Total fish-mediated carbon flux to the seafloor in the no-fishing scenario).
