Holocene vegetation history at Wet Sleddale, Cumbria, UK, including fine-resolution pollen and non-pollen palynomorph analyses at and about the Elm Decline
The vegetation history of Cumbria, in north-west England, has been intensively studied for many years by pollen analysis, particularly in the upland area of the Lake District but also the lowlands of the river Eden valley to the east and the coastal lowlands to the south and north. However, the Shap Fells, an eastern outlier of the upland massif, has so far not been the subject of palynological research despite it being an archaeologically rich a…
Latitude as a Factor Influencing Variability in Vegetational Development in Northeast England During the First (Preboreal) Holocene Millennium
In the North Atlantic region, the transition from the very cold Lateglacial Stadial (GS-1) to the temperate Holocene was abrupt, with a rapid increase in temperature of several degrees, after which the low-stature, cold-tolerant Stadial vegetation was replaced through the immigration and rapid succession of tall herb, heath, and shrub communities towards Betula woodland of varying density. In northeast England, pollen diagrams on a south to north…
Changes in preterm birth and stillbirth during Covid-19 lockdowns in 26 countries
Preterm birth (PTB) is the leading cause of infant mortality worldwide. Changes in PTB rates, ranging from −90% to +30%, were reported in many countries following early COVID-19 pandemic response measures ('lockdowns'). It is unclear whether this variation reflects real differences in lockdown impacts, or perhaps differences in stillbirth rates and/or study designs. Here we present interrupted time series and meta-analyses using harmonized data f…
Skaftafellsjökull, Iceland
A 1:5700 scale map of the recently deglaciated foreland of Skaftafellsjökull, Iceland as it appeared in 2007, depicts a typical active temperate glacial landsystem with a clear pattern of sequentially changing push moraine morphologies, including remarkable hairpin-shaped moraines, indicative of spatial and temporal variability in process-form regimes in glacier sub-marginal settings. Similar to other Icelandic glacier forelands, this demonstrate…
Periglacial geomorphology of summit tors on Bodmin Moor, Cornwall, SW England
Three maps are presented that portray the periglacial geomorphology of the three summit areas of Bodmin Moor, Cornwall, SW England, including Brown Willy (scale 1:2630), Kilmar/Bearah/Sharp tors (scale 1:3335) and Rough/Little Rough/Showery tors (scale 1:2175). Landform elements include castellated tors with well-developed cantilevered or precariously balanced corestones, summit blockfields, rock-fronted lobes thought to record former permafrost …
The glaciated valley landsystem of Morsárjökull, southeast Iceland
A 1:4470 map of the Morsárjökull foreland, southern Iceland shows the spatial distribution of post Little Ice Age glacial sediment–landform associations pertaining to the operation of a typical active temperate outlet glacier of the south Vatnajökull ice cap. The map depicts an exemplar for the debris-charged glaciated valley landsystem, with characteristics further indicative of ‘uncovered alpine glaciers’, such as the uneven distribution of mor…
Snæfellsjökull volcano-centred ice cap landsystem, West Iceland
A 1:10,526 scale map of Snæfellsjökull and its forelands is presented as the first landsystem exemplar of volcano-centred ice caps, for application to understanding glacierized volcanic terrains globally. Mapping of surface materials and landforms was undertaken using orthorectified aerial photographs taken in 2002 and results of ground truth fieldwork in 2010. Nine natural surficial geology units were identified in addition to bedrock, glacier i…
Fláajökull (north lobe), Iceland
A 1:6250 map of the foreland of Fláajökull's north lobe as it appeared in 1989, together with a 1:350 scale map of a sample area of recently exposed glacial landforms from 2014, enables an assessment of the spatial and temporal evolution of glacial landform assemblages at the margin of an active temperate piedmont lobe terminating at ice-marginal thickening till wedges. The pattern of landform development captured in these maps indicates that the…
Eiríksjökull plateau icefield landsystem, Iceland
A 1:9500 scale map of the Eiríksjökull plateau icefield and its post-Little Ice Age (LIA) foreland geomorphology and surficial geology is presented as a modern exemplar of an asymmetrically developed mountain glacier typical of the style of glacierization that dominated during mid-latitude Quaternary cold stages. Features regarded as diagnostic for this setting include (a) ice-cored hummocky terrain, indicative of controlled moraine construction …
Surficial geology and geomorphology of the Kumtor Gold Mine, Kyrgyzstan
A 1:50,000 scale map of the surficial geology and geomorphology of the mountain glacier landsystem and the human impacts of the Kumtor Gold Mine operations in the Akshiirak massif was compiled from a 0.5 m resolution pan-sharpened image from Digital Globe's WorldView-2 platform dated 5 September 2014. The map depicts 11 surficial geology units, 6 of which are classified according to natural genetic origins and 5 relating to recent human interfere…
A train journey through the English health divide
England has some of the largest spatial inequalities in health in Europe – greater, for example, than those that currently exist between the former East and West of Germany (Bambra et al., 2014). People in the North of England are consistently found to be less healthy than those in the South – across all social classes and amongst both men and women (Dorling, 2010). The reasons for this are both compositional and contextual (Macintyre et al., 200…
Heinabergsjökull and Skalafellsjökull, Iceland
A 1:15,000 scale map of the glacial geomorphology and surficial geology of the Heinabergsjökull and Skalafellsjökull glacier forelands in southeast Iceland depicts a landsystem imprint of actively receding temperate glaciers in a mountain terrain with a high glacifluvial sediment yield. The landsystem is characterised by the three diagnostic depositional domains for active temperate glacier systems (marginal morainic; subglacial; glacifluvial/gla…
Satujökull glacial landsystem, Iceland
Please click here to download the map associated with this article. A surficial geology and geomorphology map of the Satujökull foreland of the northern Hofsjökull ice cap in central Iceland provides a clear signature of spatial and temporal change in glacial landsystem signatures as a result of complex glacier behaviour in the historical period. Landsystem 1, indicative of polythermal conditions, comprises a wide arc of ice-cored moraine and con…
Surging glacier landsystem of Tungnaárjökull, Iceland
Please click here to download the map associated with this article. A1:30,000 scale map of the snout and proglacial landscape of the surging Icelandic glacier Tungnaárjökull, based upon aerial photography from 1995, immediately after a surge, allows an assessment of the spatial variability in landform-sediment imprints of catastrophic glacier advance across upland bedrock ridges. The ice-margin parallel alignment of the bedrock ridges locally str…
