4. Age constraints of the middle pleistocene till and loess sequence in northeast Missouri, USA, based on pedostratigraphy within a polygenetic paleosol.

Pre-Illinoian (pre-MIS 6) tills in northern Missouri, USA mark the southernmost advances of the early Laurentide Ice Sheet (LIS), so their ages likely correspond to its largest ice volumes. Present age constraints for the two youngest tills in this sequence (Macon and Columbia) are consistent with...

10. Ground magnetic surveying and susceptibility mapping across weathered basalt dikes reveal soil creep and pedoturbation.

Ground magnetic survey profiles across a soil-covered and weathered mafic dike in sedimentary host rock not only permit to delineate the strike, width and burial depth of the intrusive basalt sheet, but also reflect the subsurface deformation of its clayey weathering products. We illustrate this...

15. Modeling root exudate accumulation gradients to estimate net exudation rates by peatland soil depth.

Root exudates accumulate as a radial gradient around the root, yet little is known about variability at the individual root level. Vertical gradients in soil properties are hypothesized to cause greater accumulation of exudates in deeper soil through hindering diffusion, increasing sorption, and...
