[{"name":"sjostrom-2024-ireland-1","title":"Peat geochemistry, grain size, organic compounds and vegetation variability in northwestern Ireland during the last 8000 years","summary":"This dataset contains results of multi-proxy analysis of a 487 cm long peat sequence covering the last 8000 years from Roycarter Bog, County Mayo, northwestern Ireland. The chronology was established through AMS (accelerator mass spectrometry) radiocarbon dating of plant macrofossils. The sequence was analysed for bulk density, plant macrofossils, elemental composition, organic compounds, mineral content and grain size distribution.\r\n\r\nThis dataset also contains the results of elemental, grain size and mineral analysis of two beach sediments from Roycarter Beach and Doolough Beach, located nearby (within ~1.5 km) of the bog. The sediment samples were collected to infer the sources of the minerals deposited on Roycarter Bog. \r\n\r\nField-work was conducted in February 2022. The peat sequence was retrieved with a Russian peat corer equipped with a 100\u00d77.5 cm chamber. The sediment beach samples were collected in pits, ca 10 cm below the surface.\r\n\r\nThe data were used to infer past storminess variability during the last 8000 years in north-western Ireland, primarily based on the results of the grain size analysis. The bulk density and organic compound results were used to infer local hydrological variability in the bog during the studied period, also verified by plant macrofossil analysis at selected depths.","citations":"Sj\u00f6str\u00f6m JK, Gyllencreutz R, Mart\u00ednez Cortizas A, Nylund A, Piilo SR, Schenk F, McKeown M, Ryberg EE, Kylander ME (2024) Holocene storminess dynamics in northwestern Ireland: Shifts in storm duration and frequency between the mid- and late Holocene.
