Sediment and particulate carbon removal by pipe erosion increase over time in blanket peatlands as a consequence of land drainage [PDF]

, 2006
Land drainage is common in peatlands. Artificially drained blanket peat catchments have been shown to have a significantly greater soil pipe density than intact catchments.

Phantasmic Encounters in the Arctic: Haunting Materialities Beyond the Ghosts of War

Anthropology of Consciousness, EarlyView.
ABSTRACT In the vast north, ghostly experiences are common for locals and outsiders alike. Here, we explore how cultural‐natural attributes, like remoteness and extreme seasonal variation, compound experiences of the haunting in visceral ways. This provides the Arctic region with an unusually pronounced baseline of other‐than‐human agency, which in the

Soil wetting and drying processes influence stone artefact distribution in clay‐rich soils: A case study from Middle Gidley Island in Murujuga, northwest Western Australia

Archaeometry, EarlyView.
Abstract Soils that contain swelling clay minerals (e.g., montmorillonite) expand and contract during wetting and drying, causing movement within the soil profile. This process, known as argilliturbation, can alter artefact distributions, destroy stratigraphy and complicate the interpretation of archaeological deposits.

STUDY OF THE LANDFORMS OF THE IBICUÍ RIVER BASIN WITH USE OF TOPOGRAPHIC POSITION INDEX

Revista Brasileira de Geomorfologia, 2018
The Topographic Position Index (TPI) is an algorithm which calculates the difference of the elevation between a central pixel ( and the mean of the elevation of its surroundings () surroundings defined by of a radius determined by the user. The study was

Assessing the Vulnerability of an Inuit Archaeological Site in a Changing Periglacial Environment: A Novel Multimethod Geophysical Approach in Arctic Geoarchaeology

Archaeometry, EarlyView.
ABSTRACT With northern regions warming at twice the global rate, assessing the state of archaeological sites in these areas is critically important. In this study, we used a multimethod geophysical approach (ERT, GPR, and EMI) to characterize the current geocryological conditions of an Inuit archaeological site on South Aulatsivik Island (Labrador ...

An ecologic study of peat landforms in Canada and Alaska [PDF]

The role of groundwater and surface runoff in controlling the water chemistry and development of peat landforms in northern Minnesota are described. The LANDSAT imagery taken duing spring break-up are particularly valuable in identifying potential zones ...

Map Room Conversations: Mapping Objects

Area, EarlyView.
Short Abstract This article presents reflections on a ‘Map Room Conversation’ session entitled ‘Mapping Objects’ at the RGS International Conference, 2024. The session considered the three dimensional aspects of map‐making, both the objects and methods involved with producing maps, and the construction of maps in three dimensions in the form of relief ...
