ALERT: This system is being upgraded on Tuesday December 12. It will not be available
for use for several hours that day while the upgrade is in progress. Deposits to DukeSpace
will be disabled on Monday December 11, so no new items are to be added to the repository
while the upgrade is in progress. Everything should be back to normal by the end of
day, December 12.

Boom and bust carbon-nitrogen dynamics during reforestation
(Ecological Modelling, 2017-09-24)© 2017 Elsevier B.V. Legacies of historical land use strongly shape contemporary ecosystem dynamics. In old-field secondary forests, tree growth embodies a legacy of soil changes affected by previous cultivation. Three patterns ... -
Distinct contributions of eroding and depositional profiles to land-atmosphere CO <inf>2</inf> exchange in two contrasting forests
(Frontiers in Earth Science, 2019-02-26)© 2019 Billings, Richter, Ziegler, Prestegaard and Wade. Lateral movements of soil organic C (SOC) influence Earth's C budgets by transporting organic C across landscapes and by modifying soil-profile fluxes of CO 2 . We ... -
Gully-erosion estimation and terrain reconstruction using analyses of microtopographic roughness and LiDAR
(Catena, 2021-07-01)Gully mapping techniques successfully identify gullies over a large range of breadths and depths in complex landscapes but practices for estimating gully volumes need further development. Gully gap-interpolation for estimation ... -
Human-soil relations are changing rapidly: Proposals from SSSA's cross-divisional soil change working group
(Soil Science Society of America Journal, 2011-11-01)A number of scientists have named our age the Anthropocene because humanity is globally affecting Earth systems, including the soil. Global soil change raises important questions about the future of soil, the environment, ... -
Humanity's transformation of earth's soil: Pedology's new frontier
(Soil Science, 2007-12-01)Pedology was born in the 18th and 19th centuries, when soil was first conceived as a natural body worthy of its own scientific investigation. For well over a century, pedology explored soil as a system developed from a complex ... -
Making the case for a formal Anthropocene Epoch: An analysis of ongoing critiques
(Newsletters on Stratigraphy, 2017-01-01)© 2017 The Authors. A range of published arguments against formalizing the Anthropocene as a geological time unit have variously suggested that it is a misleading term of non-stratigraphic origin and usage, is based ... -
Mercury Sourcing and Sequestration in Weathering Profiles at Six Critical Zone Observatories
(Global Biogeochemical Cycles, 2018-10-01)©2018. American Geophysical Union. All Rights Reserved. Mercury sequestration in regolith (soils + weathered bedrock) is an important ecosystem service of the critical zone. This has largely remained unexplored, due to the ... -
Micro-topographic roughness analysis (MTRA) highlights minimally eroded terrain in a landscape severely impacted by historic agriculture
(Remote Sensing of Environment, 2019-03-01)© 2018 Elsevier Inc. The 190 km2 Calhoun Critical Zone Observatory in the Piedmont region of South Carolina, USA lies in an ancient, highly weathered landscape transformed by historic agricultural erosion. Following the ... -
Stratigraphic and Earth System approaches to defining the Anthropocene
(Earth's Future, 2016-08-01)© 2016 The Authors. Stratigraphy provides insights into the evolution and dynamics of the Earth System over its long history. With recent developments in Earth System science, changes in Earth System dynamics can now be ... -
The Anthropocene: A conspicuous stratigraphical signal of anthropogenic changes in production and consumption across the biosphere
(Earth's Future, 2016-03-01)© 2016 The Authors. Biospheric relationships between production and consumption of biomass have been resilient to changes in the Earth system over billions of years. This relationship has increased in its complexity, from ... -
Topographic variability and the influence of soil erosion on the carbon cycle
(Global Biogeochemical Cycles, 2016-05-01)©2016. American Geophysical Union. All Rights Reserved. Soil erosion, particularly that caused by agriculture, is closely linked to the global carbon (C) cycle. There is a wide range of contrasting global estimates of how ...
