Holocene climate change and peatland dynamics in southern Sweden based on tree-ring analysis of subfossil wood from peat deposits
… (Pinus sylvestris L.) buried in South Swedish peat deposits. By cross-dating Swedish bog-pine ring-width (RW) chronologies with corresponding material from North-west Germany, three Swedish RW chronologies were assigned absolute ages and yielded continuous, dated chronologies over the periods …

A case study on the performance of embankments on treated soft ground
… of embankments overlying soft clay and peat deposits with very stringent requirements on the time frame of construction and allowable settlements. A field program of instrumented test embankments, referred to as No-Recess, has compared the performance of five schemes for stabilizing the …

The vegetational and archaeological history of the Ingleborough Massif, North Yorkshire
… using pollen and macrofossil analysis of peat deposits in conjunction with radiocarbon dating. A transect was taken across the massif, running northwest to south-east, and peat deposits were sampled at intervals, as close to the transect as possible. This was to give a range of altitude …

Hydrologic behaviour and hydraulic properties of a patterned fen in Saskatchewan
… in the literature as having been used in peat environments. The combined results of field and laboratory drainage tests were used to obtain a general storativity with water table depth relationship in the upper peat layer. The hydraulic conductivity, measured with slug tests, the loading …

Palaeoecological studies on the Rivington Anglezarke uplands, Lancashire
… while expansive species poor vegetation over peat suggests little has changed over long periods of time. This study seeks insight into such observations by investigation of the vegetational history locked in the peat deposits. Pollen analytical and stratigraphic investigations at 10 sites …

Exploring Sediment Compaction in Experimental Deltas: Towards a Meso-Scale Understanding of Coastal Subsidence Patterns
… stratigraphic reconstruction of ancient sediment deposits. Here I present the first investigation of subsidence due to sediment compaction and consolidation in two laboratory scale river delta experiments. Compactional subsidence rates have never been thoroughly quantified in the experimental …

Composition and facies variations in mid-cretaceous gates formation coals, Northeastern British Columbia : implications for interpretation of paleo-wetland environments and assessment of coalbed methane characteristics
… flooding, to marsh environments. The Gates peats were deposited east of the rising Canadian Cordillera. This leeward position resulted in drier conditions than the humid climate normally associated with peat formation. Inertinite formed as a result of fires during periodic drought, and was …

Sustainable Management of the Historic Environment Resource in Upland Peat: A Study from Exmoor
… monuments, archaeological sites, and within peat deposits. Palaeoenvironmental remains within peat can be used to reconstruct environmental histories throughout the Holocene. Small mires in varied topographic locations can allow detailed local landscape reconstruction, setting archaeological …

A palaeolimnological study of the anthropogenic impact on dissolved organic carbon in South Swedish lakes
… study; one dominated by woodland with abundant peat deposits, and another located nearby with patches of agricultural land in an otherwise mainly forested terrain. A number of palaeolimnological methods were applied to the sediment sequences; decadal-scale variations in TOC concentration in the …

Investigations of temporal changes in climate and the geomagnetic field via high-resolution radiocarbon dating
… Sweden around 2800 cal BP was investigated. The peat record of Undarsmosse in south-west Sweden has previously indicated a change to increased storminess and wet¬ter conditions around this period. The 14C wiggle-match dating technique was applied to constrain the timing of these events. Within …
