Statement

Tephra were detected / described visually and compositional data is single-glass shard WDS-EPMA, run at the University of Cambridge. Ar-dating was carried out on manually picked K-feldspars and samples irradiated in the CLICIT facility at Oregon State University using the Alder Creek sanidine as neutron fluence monitor. 40Ar/39Ar analyses then conducted at the SUERC National Environmental Isotope Facility, following standard protocols. Age-modelling in BACON (Blaauw and Christen, 2011) combines 210Pb & 14C dates from the 25 kyr-long CHALLACEA record (Blaauw et al., 2011) with in-situ Ar-ages and the age of the YTT tephra (Mark et al., 2017). Diatom O and C isotopes measured by mass spectrometry on purified diatom samples at the British Geological Survey (BGS, Keyworth) and Lancaster University, respectively. TOC and C isotopes measured using IRMS at BGS (Keyworth).
