Summary. In August-September 1984 a 165 km long, reversed, wide-angle, seismic line was shot along part of the BIRPS WINCH deep seismic reflection profile west of Lewis in the Outer Hebrides. The experiment was recorded using a new type of sea-bottom receiver, the PUMA (Pull-Up Multichannel Array). This consists of an 1100 m long array of hydrophones connected to a sea-bottom recording package. Airgun and explosive shots recorded by the PUMA provide a densely sampled record section, allowing even low amplitude arrivals to be traced across the section. An initial, 1-D interpretation of the data reveals a crustal thickness of 27 km, and confirms that a band of reflectors seen at around 8.6 s TWT on the normal incidence data, and interpreted as the 'reflection Monol, coincide with the Moho determined by wide-angle reflections and refractions. 相似文献

Sediments of the marl lake Malham Tarn located in NW Englandpreserve an environmental record since 12 Ka. Eight Holocene pollen zones wereidentified, and the 13C of total organic carbon (TOC) showsthree stratigraphic divisions. The basal clay unit and overlayingsand/clay/marl unit have 13C of –24which decreases at the base of the principal marl unit to a mean value around–30, whilst the topmost black marl unit 13Cincreases to –28 at the surface. Representative samples of theseunits were selected for analysis of n-alkanes andn-fatty acids and their 13C.Samples of modern Chara and peat were analysed forcomparison. The clay unit has a minor contribution of redeposited matureorganic matter and autochthonous algae, the marl unit a high contribution ofChara, and the dark marl unit has a high contribution fromhigher plants. Compound-specific 13C revealssystematic differences between alkanes and fatty acids of different chainlength. The major shift in 13C in the short and medium chainfatty acids are probably due to the decreasing influence of carbonate rockflour as source of DIC. The major shift in 13C in the longchain n-fatty acids andn-alkanes could reflect the lower atmosphericCO2 concentration at Last Glacial. The negative shift of short chainfatty acids in organic rich dark marls reflects introduction of detrital peatinto the lake. The 13C results show a dramatic change fromdominance of autochthonous plus eroded sources up to Pollen Zone IV, then slowcolonisation of the hinterland by higher plants, followed by constantChara contributions throughout the deposition of the marl,and a further increase of higher plant material after the rise in water levelin 1791. 相似文献

For over a decade the New Right philosophy of Thatcherism has directed the political, economic, and social development of the United Kingdom. The pursuit of market-dominated urban policies has marginalized large sections of the population who have remained untouched by the benefits of national economic growth. The concepts of citizenship and partnership are central to the doctrine of Thatcherism. This paper examines the nature of these concepts in the context of contemporary urban development and considers how redefinition can contribute to the formulation of policies to promote the popular restructuring of urban space. 相似文献

In the U.K., refused asylum seekers who are considered destitute are provided with subsistence‐level financial support through the Azure card, a cashless technology similar to a debit card. In Australia, identical technology is used to quarantine fifty percent of the welfare benefits of mainly Aboriginal residents of the Northern Territory. In this paper, I explore the underlying state logics driving such punitive financial policies directed at these populations, arguing that cashless technologies represent a form of slow violence that employs financial tactics to undermine the provision of care for populations with precarious citizenship status. Financial tactics enact new forms of border securitization, slowly but permanently excluding people with precarious claims to citizenship from participation in the nation 相似文献
