Permafrost dynamics play an important role in high-latitude peatland carbon balance and are key to understanding the future response of soil carbon stocks. Permafrost aggradation can control the magnitude of the carbon feedback in peatlands through effects on peat properties. We compiled peatland plant macrofossil records for the northern permafrost zone (515 cores from 280 sites) and classified samples by vegetation type and environmental class (fen, bog, tundra and boreal permafrost, thawed permafrost). We examined differences in peat properties (bulk density, carbon (C), nitrogen (N) and organic matter content, C/N ratio) and C accumulation rates among vegetation types and environmental classes. ... : Supplement to: Treat, Claire C; Jones, Miriam C; Camill, Philip; Gallego-Sala, Angela V; Garneau, Michelle; Harden, Jennifer W; Hugelius, Gustaf; Klein, Eric S; Kokfelt, Ulla; Kuhry, Peter; Loisel, Julie; Mathijssen, Paul J H; O'Donnell, Jonathan A; Oksanen, Pirita O; Ronkainen, Tiina M; Sannel, A Britta K; Talbot, Julie; Tarnocai, Charles; Väliranta, Minna (2016): Effects of permafrost aggradation on peat properties as determined from a pan-Arctic synthesis of plant macrofossils.
