The impact of the structural framework of the North German Basin on Pleistocene tunnel‐valley formation

open access: yesBoreas, EarlyView.
This study contains a comprehensive regional analysis of the orientations of tunnel valleys, faults and salt structures in the North German Basin, aiming to identify correlations that might indicate a structural control on tunnel‐valley formation. A structural control on tunnel‐valley formation has been repeatedly postulated and correlations have been ...

Subtle relict channels associated with large dolines in an area formerly beneath the Laurentide Ice Sheet, northern Ohio, USA

open access: yesBoreas, EarlyView.
Low‐relief dry channels appear out of place across a glaciated karst landscape in northern Ohio. Channels are only a few metres deep cut into limestone and draped with a veneer of till. Several hypotheses are proposed for explaining the channels. Low‐relief dry channels are observed across the Bellevue‐Castalia Karst Plain of north‐central Ohio, USA ...

Use of LiDAR to derive a new model of glacial hydro‐dynamic events shaping southern Ontario landscapes, Canada

open access: yesBoreas, EarlyView.
High‐resolution LiDAR data with field validation of inferred southern Ontario ice stream terrains indicate that steady‐state ice streaming is difficult to reconcile with our observations. Rather, these new observations show strong evidence of significant fluvial scouring across the area in which meltwater sheet flow overtopped the landscape.

When do extraction rights help forests? Robustness and heterogeneity for linked interventions in the Peruvian Amazon

open access: yesConservation Science and Practice, EarlyView.
We ask whether shifting forest sensors, forest outcomes, and forest contexts adds insights concerning impacts upon forests from uncertified concessions and their eco‐certifications. Forest degradation data extend learning: uncertified concessions did not affect forest‐to‐degraded transitions yet they did lower degraded‐to‐deforested transitions ...
