First records from Laurentia of some middle Cambrian (Series 3) sponge spicules

Peel, J.S., February 2017. First records from Laurentia of some middle Cambrian (Series 3) sponge spicules. Alcheringa 41, 000–000. ISSN 0311-5518.

Spicules of the sponges Silicunculus Bengtson, Australispongia Dong & Knoll and Thoracospongia Mehl are described from the middle Cambrian (Cambrian Series 3) of North Greenland. The occurrences document the first records from the Cambrian of Laurentia of spicules initially reported from Australia. Obese spicules of Thoracospongia are now known to occur in strata of Cambrian Series 2 (Stage 4, Botoman) to Cambrian Series 3 (Stage 5 and Drumian) age in Australia, northern and southeastern Siberia and in the uppermost Henson Gletscher Formation (Cambrian Series 3, Stage 5) of western Peary Land. Morphologically similar obese spicules from the USA, Jordan, Iran and Sweden suggest an evolutionary trend towards armouring of the outer sponge surface during the middle and late Cambrian. New species described are Silicunculus saaqqutit sp. nov., Thoracospongia lacrimiformis sp. nov.

Correlation between modern plant δN values and activity areas of Medieval Norse farms

This further nitrogen isotopic study of Greenlandic Norse archaeological sites provides new evidence of the affect of past human activity on modern plant δ¹⁵N values. Grass samples were taken from a number of spatially defined features at four Norse farms and one site interpreted to be a seasonally occupied herding station (sæter). At the farms, un-naturally high δ¹⁵N values were found for plants from each sampled feature, including those from the likely infields and a churchyard. At the sæter no strong isotopic effect was expected and none was found. Comparing the data from the farms we found that the average plant δ¹⁵N values were similar for features that were functionally alike. We conclude from these observations, that the unusually high plant δ¹⁵N values reflect the strong conservation of the isotopic composition of the nitrogenous materials deposited in the past, and the magnitude of the values reflects the amount of this material admixed in the soil. The results confirm previous exploratory studies of this isotopic effect and further demonstrate its potential value as an archaeological tool.     

Environmental impacts around the time of Norse landnám in the Qorlortoq valley,Eastern Settlement,Greenland

Palynology, radiocarbon dating, and open-section stratigraphies from archaeological trenches are used to examine the impact of human activity around the time of Norse landnám on vegetation and landscape associated with a small farm (Ø34) in the Qorlortoq valley, Eastern Settlement, Greenland (61° N 45° W). Peat deposits from a mire abutting the Norse ruins revealed a discontinuous palaeoenvironmental record containing a possible hiatus from ca. AD 410–1020. Palaeovegetational data were recovered either side of this period. Pollen assemblages suggest that open Salix scrub dominated the landscape during the pre-settlement phase. The later phases of landnám resulted in the creation of hay fields and heavily-grazed grassy heath. Site abandonment is reflected by a re-expansion of Salix. This occurs shortly before the onset of deposition of a Sphagnum peat, dated to cal AD 1420–1630 (2σ) and reflecting an increase in mire surface wetness, probably in response to a deteriorating climate. Radiocarbon dates were obtained on peat and plant macrofossils sampled from either side of the proposed hiatus at two different but closely-spaced (<20 m) locations across the mire. These produced significantly different dates for the cessation of peat formation in the pre-landnám period (cal BC 2130–1770 and cal AD 240–410 respectively), but near-synchronous dates for the recommencement of peat growth (cal AD 890–1150 for peat and a probably more reliable interval of cal AD 1020–1190 based on plant macrofossils). It is suggested that this hiatus may represent the first direct evidence for peat cutting in Norse Greenland.     

A Ticking Clock? Preservation and Management of Greenland’s Archaeological Heritage in the Twenty-First Century

ABSTRACT

Evaluating the rate of deterioration at archaeological sites in the Arctic presents several challenges. In West Greenland, for example, increasing soil temperatures, perennial thaws, coastal erosion, storm surges, changing microbial communities, and pioneer plant species are observed as increasingly detrimental to the survival of organic archaeological deposits found scattered along the country’s littoral zones and extensive inner fjord systems. This article discusses recent efforts by the REMAINS of Greenland project for developing a standardised protocol that defines the archaeological state of preservation, the preservation conditions, and asset value of organic deposits. Special emphasis is given to the degradation of materials such as bone and wood that are historically observed to be well-preserved in Greenland but now currently at risk. The protocol provides a baseline for monitoring future changes and will assist archaeologists in Greenland with a procedure for documenting and predicting areas of increasing vulnerability due to a warming climate.     

The Impact of Climate Change on an Archaeological Site in the Arctic

Climate change may accelerate the degradation of archaeological sites in the Arctic and lead to a loss of important historical information. This study assesses the current preservation conditions and the processes controlling the physical and chemical stability of the Qajaa kitchen midden in western Greenland. Currently, the site is well protected by low ground temperatures, permafrost and a high water/ice content, keeping the deposits anoxic. Based on 5 years of monitoring data, degradation experiments and model simulation, our results suggest that the combined effects of permafrost thaw, thermal and hydrological erosion and oxygen exposure may lead to substantial loss of archaeological evidence before the end of the 21st century.     

Stable nitrogen isotopic examination of Norse sites in the Western settlement of Greenland

To continue to explore the impact of past human activity on the stable nitrogen isotope ratios of modern vegetation, we have measured the δ¹⁵N values of plants now growing on several ancient farmsteads in the Western Settlement of Norse Greenland. Although this new test area is some 400 km north and in a different ecoregion from the previous study area, the same isotopic effect was observed. A clear isotopic signature was found on the ancient farms which could be directly correlated to past activity areas; in particular, the infields. Further, the magnitude of the δ¹⁵N values was found to be similar between study areas, indicating the same interpretative framework can be applied in widely separate geographic regions. A first test of different plant species showed that although the magnitude differed greatly the same basic information was found for functionally different plants. These observations provide additional information to aid in future archaeological application of this newly observed phenomenon.     

Arctic archaeological sites threatened by climate change: A regional multi-threat assessment of sites in south-west Greenland

Climate change threatens many well-preserved archaeological sites in the Arctic. The paper presents the first Arctic multi-threat assessment focusing on the Nuuk region of Greenland. The results suggest that the majority of the 336 known archaeological sites are already exposed to impacts from microbial degradation, permafrost thaw and vegetation, and that these impacts will increase over the next 80 years. Additional impacts from coastal erosion are only noted at a limited number of sites due to a predominant consolidated and uplifting coast. The applied methods represent an important first step to identify threatened sites and emphasize important data limitations.     

Reproducing the indigenous: John Møller’s studio portraits of Greenlanders in context

Between 1889 and 1922, John Møller (1867–1935), the first professional Greenlandic photographer, produced more than 3000 glass plate negatives documenting life in Western Greenland around the turn of the twentieth century. Rooted in an internal understanding of self, Møller’s photographs played an important part in the formation of a contemporary image of Greenlandic indigenous identity. At the same time, Møller’s photographic practice was arguably entangled in and delimited by a historical reality that was structured by colonial relations of power. This paper examines the social and art-historical contexts of Møller’s work, focusing in particular on a selection of his formal studio portraits. My reading of these portraits suggests a case in which conflicting impulses coincide. On the one hand, Møller produced images that played out the “ethnographic convention”, a European form of representation dating back to the sixteenth century used for the documentation of non-Western indigenous peoples as specimens. However, in acting out that convention, Møller’s photographs hint at a subtle, progressive building-up of identity that reclaimed images of Greenlanders for themselves, and turned an originally negative, external image of indigeneity into a positive sense of self.

Tourism and cultural encounters in ‘the last frontiers’

Host-guest encounters often play a key role within tourist experiences of culture and heritage. However, these encounters have increasingly been seen to shape and negatively influence local culture. In his report from early 2011, Shackel presents an example of the cultural encounter between local residents and one-day tourists arriving to the Eastern Greenlandic village of Kulusuk. While much of his account revolves around the covert resistance of locals, he also critically addresses the validity of authentic tourist experiences. This brief note attempts to elaborate on the concept of authenticity, and suggests some issues to consider when discussing tourist experiences, local resistance and future tourism developments in a place like Kulusuk.
