Shore

Lake level fluctuations, loose silt bottom, lack of natural anchorages, and on-shore prevailing winds, endangered navigation on the Dead Sea and prevented the long-term planning, construction and maintenance of shore-based harbour installations. A recently discovered artificial stone mound off the northern shore of the Dead Sea is a maritime-related archaeological find exposed by the drying out of the lake. The construction of this site and another site nearby inside the lake away from its historic shore was intended to create an open-water mooring designed to overcome some of the for cited challenges. In turn they allowed the use of this economically and strategically important part of the lake by maritime traffic.

Nel Bacino di Tarquinia (Lazio nord-occidentale) è presente una successione plio-pleistocenica connessa a tre cicli deposizionali trasgressivi. Essa comprende il Sintema di S. Savino (peliti di ambiente circolitorale) del Pliocene inferiore, cui seguono il Sintema di Tarquinia con i due membri eteropici del Macco (calcareniti organogene e sabbie ibride) e delle Sabbie di Poggio Gallinaro (sabbie ibride) del Pliocene medio-superiore e il Sintema di Poggio Martino (sabbie e ghiaie di spiaggia) del Pliocene superiore-Pleistocene inferiore. Quest’ultimo corrisponde al terrazzo marino più antico (circa 175 m s.l.m.) dei cinque individuati nel Quaternario nel Bacino di Tarquinia. Sono stati prelevati 646 ciottoli delle ghiaie del Sintema di Poggio Martino in quattro stazioni di campionamento e divisi in 4 classi granulometriche individuabili attraverso la misura dell’asse medio b (8–16 mm; 16–32 mm; 32–64 mm; 64–128 mm). L’analisi tessiturale ha evidenziato una misura media di b variabile...

In 2006 a palisade enclosure dated to the late Middle Neolithic was excavated at Bunkeflostrand, Malmö, Sweden. The excavation of pits and wells containing flints, animal bones and pottery revealed a wide range of activities at the site, which is exceptional in comparison with most other palisade enclosures of southern Scandinavia. Palisade enclosures have emerged as places of great significance to our understanding of cultural relations traditionally associated with the transition from the Funnel Beaker culture to the Battle Axe culture. The results of the excavation at Bunkeflostrand and other palisade enclosures in the region can be used to understand social relations and cultural change in the Middle Neolithic in southern Scandinavia.

This article focuses on the quantification of retreat rates, geomorphological processes, and hydroclimatic and environmental drivers responsible for the erosion of an unconsolidated fine-sediment cliff along the north shore of the Gulf of St. Lawrence (Quebec, Canada). Annual monitoring using field markers over a period of twenty years, coupled with photo interpretation and historical archive analysis, indicates an average annual erosion rate of 2.2 m per year between 1948 and 2017. An acceleration in retreat occurred during the last 70 years, leading to a maximum between 1997 and 2017 (3.4 m per year) and 2000–2020 (3.3 m per year). Daily observations based on six monitoring cameras installed along the cliff between 2008 and 2012 allowed the identification of mechanisms and geomorphological processes responsible for cliff retreat. Data analysis reveals seasonal activity peaks during winter and spring, which account for 75% of total erosional events. On an annual basis, cryogenic pr...

Shores of eastern Hokkaido rose by perhaps I m a few centuries ago. The uplifted area extended at least 50km along the southern Kuril Trench. It included the estuaries Akkeshi-ko and Hichirippu, on the Pacific coast, and Furen-ko and Onneto, which open to the Okhotsk Sea. At each estuary, intertidal and subtidal flats rose with respect to tide level; wetland plants colonized the emerging land; and peaty wetland deposits thereby covered mud and sand of the former flats. Previous work at Akkeshi-ko and Onneto showed that such emergence occurred at least three times in the past 3000 years. Volcanic-ash layers date the youngest emergence to the seventeenth century AD. New evidence from Akkeshi-ko, Hichirippu and Furen-ko clarifies the age and amount of this youngest emergence. Much of it probably dates from the century's middle decades. Some of the newly emerged land remained above high tides into the middle of the eighteenth century or later. The emergence in the last half of the s...

New evidence from Akkeshi-ko, Hichirippu and Furen-ko clarifies the age and amount of this youngest emergence. Much of it probably dates from the century's middle decades. Some of the newly emerged land remained above high tides into the middle of the eighteenth century or later. The emergence in the last half of the seventeenth century probably exceeded 0.5 m (inferred from stratigraphy and diatom palaeoecology) without far exceeding I m (estimated by comparing seventeenth-and eighteenth-century descriptions of Akkeshi-ko). The stratigraphy and palaeoecology of the emergence are better explained by tectonic uplift than by bay-mouth blockage, tidal-flat accretion or sea-level fall. Eastern Hokkaido needs occasional uplift, moreover, to help reconcile its raised marine terraces with its chronic twentieth-century subsidence. Because it took place above forearc mantle, eastern Hokkaido's seventeenth-century uplift probably lacks analogy with coseismic uplift that occurs above typical plate-boundary ruptures at subduction zones.

The historical shoreline change from 1978 to 2017 along Odisha coast are studied using toposheet, time-series Landsat, Indian Remote Sensing satellite data, and observed data. Shoreline change at south Odisha coast, Puri, Konark, Paradip and Pentha at different epochs (3–12 yrs) during 1978–2017 shows distinct spatio-temporal variability, which is discussed in relation to cyclonic storms and coastal structures associated with ports and harbours. The study also generated a long-term (1978–2017) shoreline change statistics (EPR, LRR, SCE and NSM) using Digital Shoreline Analysis System (DSAS) at every 500 m interval for the five zones of Odisha coast covering 425 km, identified the hotspots of erosion and accretion and divided the shoreline into five different classes of erosion and accretion. Identified lengths of shoreline with high erosion, low erosion, stable, low accretion and high accretion are respectively, 257.1, 92.2, 25.5, 10.2 and 40 km, based on LRR. The results indicate that erosion is predominant along Odisha coast. Zone-D (Paradip to Pentha) with highest percentage of high erosion is most vulnerable, while Zone-E (Pentha–Balasore) with highest percentage of accretion is least vulnerable. Zone-B (Chilika to Konark) with lowest percentage of high erosion and no high accretion is stable.

This study was conducted to evaluate the impact of human activities on the ecological health and food chain at the shores of four Nile Islands in Great Cairo including El-Qeratten, El-Waraq, El-Zamalek, and El-Manial. Water quality, bacteria, phytoplankton, benthic algae, zooplankton, macrobenthic invertebrates, and bony fishes were examined at each island shore over two seasons including the lowest and the highest flow (February and July 2020, respectively). The obtained results showed that the average values of most of the chemicals in Nile Island’s water were within the Egyptian water quality limits. Discriminant analysis of physicochemical factors revealed a similarity between El-Waraq and El-Qerateen and between El-Manial and El-Zamalek. El-Qeratten was the most polluted island. It has the highest total and fecal coliform bacteria count (3.155 and 3.050 Log MPN/100 mL, respectively). El-Zamalek shores have the highest phytoplankton (33,582 cells × 104 L−1) and zooplankton count...

Abstract: Sand has become such a powerful visual, emotive and experiential component of tourism. This essay ventures an ontological explanation for the Western world's acquired and now gripping fascination with this particularly mundane material, and its robust current connection with the tourism industry. The paper argues that this engagement with sand's materiality is a culturally determined response, an extension of an encounter with what is seen to be real, in the context of a contemporary experience that is increasingly given over to virtual objects and representations. An anthropology of sand-a conjunction of the cultural and material-with a particular focus on beach tourism, offers a complex, multi-layered experience where the real and the fictive are mutually constituted.

New radiocarbon dates obtained from Late Pleistocene and Holocene deposits of the southern, eastern, and northern shores of Lake Baikal in 1995–2001 are presented, and the most important results of paleoenvironmental studies based on C data are discussed. The following paleogeographic events were verified with the help of C dating: 1) first Late Pleistocene glaciation (Early Zyryan); 2) Middle Zyryan interstadial; 3) loess formation during the Late Zyryan (Sartan) deglaciation; 4) warm and cold events in the Late Glacial; and 5) vegetation changes and forest successions during the Late Glacial and Holocene.
