Archaeological applications of airborne lidar topographic data are now well established and documented. However, less well explored by archaeologists and palaeoenvironmentalists are the potential applications of lidar intensity data. Here we explore this potential to remotely determine the differential preservation potential of valley floor sediments, within a temperate, lowland environment, especially where preserved within palaeochannels. We compare airborne lidar intensity data with simultaneously collected terrestrial records of sediment organic content, moisture and stratigraphy. Results suggest that while a correlation exists between lidar intensity values and sediment properties, it is neither linear nor robustly predictable. Nevertheless it is suggested that examination of lidar intensity data serve a useful purpose when assessing valley floor alluvial sediments. 相似文献

Quaternary stratigraphy and sea level changes have been extensively investigated in many areas of the Mediterranean. However, numerical dating of coastal deposits and the associated paleoenvironmental information are limited for the coasts of Cyprus, principally based on radiometric and radiation-exposure geochronological techniques on fossils which bear a range of limitations and uncertainties. As such, optically stimulated luminescence (OSL) dating techniques are deemed to be the most suitable in direct dating of the coastal sediments of Cyprus. In the southeastern Cyprus, coastal dunes (aeolianites) now forming elongated ridges appear as morphological features running parallel to the current shoreline presenting an indicator of sea level and climate changes of great paleoenvironmental significance. We present our first chronological results for the exposed aeolianites and underlying littoral deposits formed along the southeastern coastal Cyprus ranging from 78.4 ± 9.9 to 56.2 ± 7.4 ka. The post-infrared–infrared stimulated luminescence (pIR-IRSL) revealed that dune formation took place during the marine isotope stages (MISs) 3, 4, and possibly 5a. Late Holocene reworking is proposed for a distinctively isolated dune with an age of ~1.3 ka ago. This study also showed that pIR-IRSL dating of feldspars may be a reliable alternative to quartz OSL dating when the quartz luminescence characteristics are unsuitable. 相似文献

Among one of the more significant societal impacts of the COVID-19 pandemic, restrictions on people's movement accelerated, and in some cases outright caused, restaurant closures. By considering people's potential for both driving and walking to restaurants, this study aims to examine how restaurant closures are associated with neighborhood characteristics during the pandemic. To do so, we investigated changes in spatial accessibility to restaurants, identified hot spots of communities with large accessibility reductions, and explored relationships between the reductions and neighborhood characteristics in Leon County, Florida. Analysis showed that the area experiencing the largest reductions in spatial access to restaurants varied by transportation modes and the overall geographic patterns in accessibility reductions significantly differed. Communities with significant reductions in car-based accessibility were areas with a small percentage of the older and non-White populations and a longer distance to the central area. On the other hand, only being a shorter distance to the central area was more related to hot spots of changes in walking accessibility. Findings show geographic patterns of restaurant closures, which interacted with people's modes of transportation. As such, the closures most substantially affected people in more suburban areas who might rely on driving during the pandemic. 相似文献

Presented here are the results of archaeoparasitological analysis of habitation layers at Shag River Mouth, Otago coast. Two types of helminth eggs were identified: The first type is Toxocara canis, associated with the introduced kurī dog (Canis familiaris), which could have adversely affected local people and their dogs. The other type very closely resembles that of Stringopotaenia psittacea, associated with the critically endangered endemic kākāpō (Strigops habroptilus) parrot. The results represent the first South Island archaeo parasitological identifications. There was no starch or associated material in the samples, such as introduced Polynesian crops and indigenous starchy Māori food plants. This lack is consistent with the interpretation of the site as that of a transient village focused on big game hunting. 相似文献

In the context of discipline-wide efforts to produce more inclusive, just, and equitable norms of geographical knowledge production, section editors for Geography Compass identify five concrete practices by which to address systemic inequities, injustices, and exclusions through their editorial work. 相似文献
