Considerations of the mortuary behavior at Sunghir concern principally the two elaborate graves, Graves 1 and 2. Although each exhibits patterns evident elsewhere in Mid Upper Paleolithic burials, the combinations of features and the richness of the two graves is truly exceptional. Yet there is additional evidence for mortuary behavior, principally associated with the Sunghir 5 cranium and for the burial above Grave 2 (here designated as Grave 2bis). The Sunghir graves have been described in detail by O.N. Bader (1998), and additional analyses of the associated materials have been done by White (1993, 1999) and Khlopachev (2006). Information on them is available from additional sources (e.g., Bader 1978; Soffer 1985; Abramova 1995; Bader and Bader 2000; Pettitt 2011), as well as from numerous short reports. Of these, the primary sources are those of O.N. Bader from the excavations and excavation analysis and of White and Khlopachev from analysis of the original material in the Vladimir District Regional Museum. The description here is an amalgamation of information from these and other sources. There are some inconsistencies between the different sources, and when possible they have been sorted out using the diagrams, and especially the discussion and in situ photographs, provided by O.N. Bader (1998). In the discussions of the graves and their contents, it should be kept in mind that many of the objects found in the graves and clearly associated with the human remains also occur in reasonable numbers in the cultural layer (cf. Bader 1978). This applies to the ochre, the several varieties of ivory beads, small stone pendants, animal figurines, tubular bones, pierced canines (arctic fox and wolf), and ivory spears (or fragments thereof). Additional decorative objects not found in the burials, such as shell beads and engravings, also derive from the cultural layer. It remains unclear whether these finds from the cultural layer were artifacts and aspects of body decoration that were common among the individuals at Sunghir (some of which happened to be preserved in abundance in the graves), whether their occurrence in the cultural layer is the result of pieces lost in the process of preparing the burials, whether the isolated pieces are from disturbed (unknown) burials, or whether (as suggested by Bader 1978) they come from discarded pieces of clothing.

Abstract Mineralogical and textural variability of ores from different sources commonly leads to processing inefficiencies, particularly when a processing plant is designed to treat ore from a single source (i.e. ore of a relatively uniform composition). The bulk of the Witwatersrand ore in the Klerksdorp goldfield, processed at the AngloGold Ashanti Great Noligwa treatment plant, is derived from the Vaal Reef (>90%), with a comparatively small contribution obtained from the Crystalkop Reef (or C-Reef). Despite the uneven contribution, it is of critical importance to ensure that the processing parameters are optimized for the treatment of both the Vaal and C-Reefs. This paper serves to document the results of a geometallurgical study of the C-Reef at the Great Noligwa gold mine in the Klerksdorp goldfield of South Africa, with the primary aim of assessing the suitability of the processing parameters that are in use at the Great Noligwa plant. The paper also draws comparisons between the C-Reef and the Vaal Reef A-facies (Vaal Reef) and attempts to explain minor differences in the recovery of gold and uranium from these two sources. Three samples of the C-Reef were collected in-situ from the underground operations at Great Noligwa mine for mineralogical analyses and metallurgical tests. Laboratory-scale leach tests for gold (cyanide) and uranium (sulphuric acid) were carried out using dissolution conditions similar to that in use at the Great Noligwa plant, followed by further diagnostic leaching in the case of gold. The gold in the ore was found to be readily leachable with recoveries ranging from 95% to 97% (as opposed to 89% to 93% for the Vaal Reef). Additional recoveries were achieved in the presence of excess cyanide (96% to 98%). The recovery of uranium varied between 72% and 76% (as opposed to 30% to 64% for the Vaal Reef), which is substantially higher than predicted, given the amount of brannerite in the ore, which is generally regarded as refractory. Thus, the higher uranium recoveries from the C-Reef imply that a proportion of the uranium was recovered by the partial dissolution of brannerite. As the Vaal Reef contain high amounts of chlorite (3% to 8%), which is an important acid consumer, it is considered likely that this could have reduced the effectiveness of the H2SO4 leach in the case of the ore of the Vaal Reef. Since the gold and uranium recoveries from the C-Reef were higher than the recoveries from the Vaal Reef, the results demonstrate that the processing parameters used for treatment of the Vaal Reef are equally suited to the treatment of the C-Reef. Moreover, small processing modifications, such as increased milling and leach retention times, may well increase the recovery of gold (particularly when e.g. coarse gold, or unexposed gold, is present).

<p>This presentation discusses a downstream application from Copernicus Services, developed in the framework of the IMPRESSIVE project, for the monitoring of  the oil spill produced after the crash of the ferry “Volcan de Tamasite” in waters of the Canary Islands on the 21<sup>st</sup> of April 2017. The presentation summarizes the findings of [1] that describe a complete monitoring of the diesel fuel spill, well-documented by port authorities. Complementary information supplied by different sources enhances the description of the event. We discuss the performance of very high resolution hydrodynamic models in the area of the Port of Gran Canaria and their ability for describing the evolution of this event. Dynamical systems ideas support the comparison of different models performance. Very high resolution remote sensing products and in situ observation validate the description.</p><p>Authors acknowledge support from IMPRESSIVE a project funded by the European Union’s Horizon 2020 research and innovation programme under grant agreement No 821922.

Abstract. In situ measurements of snow water equivalent (SWE) – the depth of water that would be produced if all the snow melted – are used in many applications including water management, flood forecasting, climate monitoring, and evaluation of hydrological and land surface models. The Canadian historical SWE dataset (CanSWE) combines manual and automated pan-Canadian SWE observations collected by national, provincial and territorial agencies as well as hydropower companies. Snow depth and derived bulk snow density are also included when available. This new dataset supersedes the previous Canadian Historical Snow Survey (CHSSD) dataset published by Brown et al. (2019), and this paper describes the efforts made to correct metadata, remove duplicate observations, and quality control records. The CanSWE dataset was compiled from 15 different sources and includes SWE information for all provinces and territories that measure SWE. Data were updated to July 2020 and new historical data from the Government of Northwest Territories, Government of Newfoundland and Labrador, Saskatchewan Water Security Agency, and Hydro Quebec were included. CanSWE includes over one million SWE measurements from 2607 different locations across Canada over the period 1928–2020. It is publicly available at https://doi.org/10.5281/zenodo.4734372 (Vionnet et al., 2021).

This paper deals with a possible interpretation value of biochemical methods in comparison with the classic tools of geoarchaeology for the evaluation of formation processes. Organic rich layers from the archaeological site Brandýs nad Labem-Vrábí were tested with the aim to determine the origin of several different types of soil organic material by analyzing the content of different sugars. The studied soil body showed signs of cultural layer, redeposited soils, and in situ developed soil. The analysis of different sugars was highlighted: soil samples taken from these layers were analyzed to assess the ratios of mannose + galactose to arabinose + xylose, and of rhamnose + fucose to arabinose + xylose, content of Corg and different nitrates, as well as different rates of absorbance. The results show that the interpretation values of polysaccharides evaluation didn’t bring significant results itself, but in combination with classical tools of geoarchaeology may bring interpretable and new results.

In addition to the functional, anatomical, and paleopathological reflections of the biology and behavior of the Sunghir humans, it has been possible to make indirect inferences regarding their average dietary profiles. These considerations derive from the mineral compositions of bone samples from Sunghir 1 to 4 (Kozlovskaya 2000d), carbon and nitrogen stable isotope data from the bone collagen of Sunghir 1 to 3 (Richards et al. 2001; Dobrovolskaya et al. 2012), and postcanine buccal microwear for Sunghir 1 to 3 (Pinilla 2012; Pinilla and Trinkaus in press). As noted in chapter 2, the site contained an abundance of large mammal remains, of which the bison, horse, saiga, and especially reindeer remains were undoubtedly brought to the site for human consumption. There was also an abundance of mammoth remains. There has been an ongoing debate as to the extent to which the mammoth remains, found at a number of central and eastern European and Siberian Mid Upper Paleolithic (MUP) sites, reflect human consumption, are largely incidental to the human presence having accumulating along the banks of gullies and streams, and/or were gathered from the landscape for use as raw material and even fuel (e.g., Soffer 1985; Derevianko et al. 2000; Svoboda et al. 2005; Wojtal and Wilczyński 2013). Systematic taphonomic analysis of the Sunghir faunal assemblage has not been undertaken, but Bader (1978) did notice the differential presence of mammoth skeletal elements at Sunghir, suggesting differential transport of body portions presumably for human consumption. Moreover, the mammoth bones were distributed through the cultural layer and apparently did not exist as a bone accumulation on the periphery of the site. At the same time, the faunal profile of the cultural layer contained a diversity of carnivores, of which the cave lions, wolves, and possibly brown bears could have been partially responsible for some of the herbivore remains at the site. It is possible that humans were hunting and eating the bears, given occasional cutmarks on bear bones at other MUP sites (Wojtal 2000; Münzel and Conard 2004).

When evaluating information, we cannot always rely on what has been presented as truth: Different sources might disagree with each other, and sometimes there may be no underlying truth. Accordingly, we must use other cues to evaluate information—perhaps the most salient of which is consensus. But what counts as consensus? Do we attend only to surface-level indications of consensus, or do we also probe deeper and consider why sources agree? Four experiments demonstrated that individuals evaluate consensus only superficially: Participants were equally confident in conclusions drawn from a true consensus (derived from independent primary sources) and a false consensus (derived from only one primary source). This phenomenon was robust, occurring even immediately after participants explicitly stated that a true consensus was more believable than a false consensus. This illusion of consensus reveals a powerful means by which misinformation may spread.
