A 520-year paleolimnological grain size and ITRAX record from Harvey Lake, New Brunswick, Canada

This grain size data was derived from a 250 mm long gravity Glew Maxi core (HL-2017-GC-2) collected from near the mouth of Herbert's Cove, Harvey Lake, New Brunswick Canada (45°43’42.535” N; 67°01’23.739” W) at a water depth of 4.5 m.  The core was subsampled on-site at 2 mm resolution using a Glew core extruder before transport to Carleton University for subsequent analysis. Subsamples were analyzed using a Beckman Coulter LS 13 320 laser diffraction grain size analyzer equipped with a universal liquid module.  The resultant triplicate grain size data were averaged using a script within Matlab which generated the data archived here.  The data was then analyzed using End Member Mixing Analysis and three distinct end members were recognized EM01, Mode = 05 μm; EM02, Mode = 27μm; EM03, Mode = 58 μm). Subsequent radiocarbon dating revealed that deposition spanned the last 520 years of deposition. During this interval there were 12 major storms (EM03) and analysis of precipitation data from...
