Evidence for bioturbation of luminescence signals in eolian sand on upland ridgetops, southeastern Minnesota, USA

Chronology of dune development in the White River Badlands, northern Great Plains, USA

“…2). The majority of samples were collected using hand augers at depths between 1 and 3m below ground surface to minimize potential effects of bioturbation (Hanson et al, 2015). At auger and exposure localities, sediment was collected by inserting tubes into a full bucket auger or exposure face.…”

Eolian sand and loess deposits indicate west-northwest paleowinds during the Late Pleistocene in western Wisconsin, USA

“…Large-scale, Late Pleistocene transport of loess on generally westerly winds, out of north-south flowing meltwater river valleys, has long been known for this region and is therefore not shown here. Compiled from Arbogast et al (2015Arbogast et al ( , 2017, Campbell et al (2011), Colgan et al (2017, Hanson et al (2015), Kilibarda and Blockland (2011), Krist and Schaetzl (2001), Loope et al (2004), Rawling et al (2008), Schaetzl et al (2014Schaetzl et al ( , 2016, Stanley andSchaetzl (2011), andVader et al (2012). Black arrows indicate data from dunes, gray arrows indicate data from loess, dashed arrows indicate data from spits or other features.…”

Natural and human-induced prehistoric and historical soil erosion and landscape development in Southwestern Tennessee, USA

“…In this paper, the AMS data are presented with the 2s confidence interval. To identify the exact sediment age, we also selected six samples for OSL dating which were collected from a minimum depth of 0.8 m to limit the potential impact of bioturbation (Hanson et al, 2015). Sample preparations and luminescence measurements were conducted at the Luminescence Geochronology Laboratory at the University of Nebraska-Lincoln, NE, USA.…”
