Soil biodiversity and network complexity jointly drive soil multifunctionality in an open cast coal mine

open access: yesFrontiers in Microbiology
IntroductionIntensive opencast coal mining has severely degraded soil ecosystem structure and function. Although ecological reclamation enhances soil biodiversity and multifunctionality (SMF), the underlying mechanisms—particularly how reclamation ...

Loess Tourism Resource Exploitation Strategy in the Chinese Loess Plateau: A Case Study of White Deer Plateau

open access: yesJournal of Geography and Geology, 2009
As one of the important geologic tourism resources in the world, the Chinese loess landscape tourism has not beendeveloped deeply enough, which can not fulfill tourists’ tourism demands on different levels. Based on many successfuldevelopment experiences about sand tourism and ice snow tourism, according to the feature of loess environment,geographic ...

The Spokane flood controversy [PDF]

open access: yes
An enormous plexus of proglacial channels that eroded into the loess and basalt of the Columbia Plateau, eastern Washington is studied. This channeled scabland contained erosional and depositional features that were unique among fluvial phenomena ...

Out in the cold? A review of Early Middle Palaeolithic settlements in northern Central Europe, age data and geological preconditions for site formation and preservation

open access: yesBoreas, EarlyView.
The characteristics of settlement of Neanderthals in northern Central Europe during the earlier phases of the Middle Palaeolithic (Marine Isotope Stage 8–6) have been a matter of debate for decades, specifically regarding the population dynamics at such latitudes during the coldest phases. In this paper, we review the known archaeological record of the

The spatial variation of Asian dust and marine aerosol contributions to glaciochemical signals in central Asia [PDF]

open access: yes, 1992
Short-term (6 months to 17 years) glaciochemical records have been collected from several glacier basins in the mountains of central Asia. The spatial distribution of snow chemistry in central Asia is controlled by the influx of dust from the large ...

A detailed post-IR IRSL chronology for the last interglacial soil at the Jingbian loess site (northern China) [PDF]

open access: yes, 2015
The chronology of dust deposition and climate during the last interglacial is poorly known on the Chinese Loess Plateau. Here, 51 samples were taken from the similar to 5 m S1 palaeosol (MIS5) at the desert marginal Jingbian site to develop what is ...

Refining the timing of Middle Pleistocene (MIS 12 to MIS 6) ice advances into northern central Europe: sedimentological analysis and single‐grain luminescence dating of glaciotectonic complexes and tunnel‐valley fills

open access: yesBoreas, EarlyView.
We summarize the current state of knowledge on the age of the Middle Pleistocene ice advances into northern central Europe and provide 25 new single‐grain feldspar luminescence ages of Elsterian and Saalian glacigenic sediments to constrain the age of the ice advances and their tentative correlation with marine isotope stages/substages.

Observations of heterogeneous reactions between Asian pollution and mineral dust over the Eastern North Pacific during INTEX-B [PDF]

open access: yes, 2009
In-situ airborne measurements of trace gases, aerosol size distributions, chemistry and optical properties were conducted over Mexico and the Eastern North Pacific during MILAGRO and INTEX-B.

Palaeowinds and depositional conditions from Holocene loess in Sweden and Finland

open access: yesBoreas, EarlyView.
The nature of deglacial and Holocene wind regimes in Fennoscandia is debated, as is the degree to which wind‐blown loess deposits exist in the region. Loess deposits in Fennoscandia are often relatively thin, discontinuous and less well‐sorted than typical loess, and questions remain over the degree of their post‐depositional reworking and the impact ...

Age of the Rotoehu Ash. Comment. [PDF]

open access: yes, 1995
Suggests that the article by Whitehead & Ditchburn (1994), although presenting useful new data on 230Th/232Th analyses, is flawed and misleading in suggesting that the Rotoiti Tephra is considerably younger than c.
