Testo completoThe medieval Norse colonization of Greenland (986-1450 AD) and the subsequent reestablishment of agriculture in south Greenland, aided by recent climate warming, constitute a conceptual model that is particularly well adapted to understanding the relations between a community and its environment. In this perspective, a multi-parameter sedimentological study was undertaken on the sedimentary sequence of Lake Igaliku (N61°00’22”, W45°26’28”), situated in the heart of the medieval and current agricultural sector. The 4 m long sequence, covering the entire Holocene evolution of the lake (~10 000 years), was studied at high temporal resolution. The analyses included the physico-chemical characterization of the sediments (density, magnetic susceptibility, XRF, X-ray imaging, grain size, carbon, nitrogen, and sulphur content, ICP-AES, δ13C and δ15N isotopic ratios) as well as the biological components of the sediment (pollen, non-pollen palynomorphs, diatoms). 28 radiocarbon dates as well as 210Pb and 137Cs measurements created a precise temporal framework with which to reconstruct the postglacial evolution of the lake and its catchment in terms of isostatic constraints, climatic forcing and anthropogenic impacts. The first phase of basin evolution is primarily controlled by isostasy, with the rapid transition from glaciomarine conditions to a freshwater lake as the basin emerged from the fjord 9500 yr BP. Afterwards, the sedimentary sequence records the paleoclimatic evolution of the region. Paleolimnological and terrestrial proxies suggest an early warm phase likely interrupted by a cold, windy, dry period between 8600 yr BP and 8100 yr BP. A second dry, windy period between 5300 yr BP and 4800 yr BP predated the transition to neoglacial cooling, which is characterised at Igaliku by a switch to humid and perhaps cooler conditions after 4800 BP, and which caused a major shift in both aquatic and terrestrial ecology. Approximately 1000 AD, after the arrival of Norse settlers, the lacustrine system became anthropogenically dominated. Land clearing and domestic herbivores introduction in the lake catchment doubled the rate of soil erosion (from 4 mm century-1 to 8 mm century-1 by 1200 AD) and caused a major modification of the organic carbon influx. On the other hand, diatom assemblages demonstrate that the lake ecology was not strongly impacted by medieval agriculture at this site. After 1325 AD, until the end of the Norse tenure in the mid-15th century, terrestrial vegetation showed signs of rebound and soil erosion decreased. This agricultural diminishment, probably in relation to the beginning of the Little Ice Age, is consistent with an important change in subsistence patterns evidenced by archaeology in this region. The reestablishment of agriculture at the beginning of the 20th century marks the reinvigoration of erosional processes that are similar in intensity to that of the Norse settlement. On the other hand, the intensification and modernization of farming practices during the 1980s is responsible for marked soil erosion (21 mm century-1) and a shift in lake ecology (eutrophication) that is unprecedented in the 9500 yr history of the lake. The combined effects of agriculture and climate warming already underway (initiated in the 1920s at Igaliku) will have large environmental consequences for the future of this region

Testo completoInsight into the relative importance of sheep and goat herding and of the economic significance of each species (i.e., milk vs. meat vs. wool) in Medieval Greenland is obtained through the application of Halstead et al.¿s (2002) criteria for the identification of adult ovicaprine mandibles to faunal assemblages from three Norse farmsteads: Sandnes, V52a, and Ø71S. The economic strategies identified are broadly comparable between the two species and the Eastern and Western Settlement sites examined, and are suggestive of the subsistence production of meat and milk. Comparison with farmsteads elsewhere in Greenland indicates that socio-economic status and/or farmstead size interacted with geographical location in determining the economic strategies employed by the Norse farmers. A broader use of resources and a more varied diet are evident at larger farmsteads in Greenland and this paper suggests that such sites would have been better able than their smaller counterparts to withstand environmental deterioration during the early Middle Ages. These analyses have also confirmed that goats were relatively more common in Norse sites in Greenland than in Norse sites in Iceland, Orkney, or Shetland.

Greenland as the biggest island in the world, has an essential role in the global warming research. The ice covers almost 80 % of Greenland’s surface, and it is the second biggest ice on earth after Antarctica. If all the ice on Greenland melted, it will cause the rising of sea level in the world by 7 meters. We study the ambient seismic noise in Greenland and the surrounding area by using the probability density function – power spectral density (PDF-PSD) method. We have processed 34 seismic recording data during 2016 to 2017 for the Z component into PSD and spectrogram. From this PSD and spectrogram, we can divide the result into the short period band (0.1 – 1 s), secondary microseism band (3 – 10 s) and primary microseism band (10 – 20 s). The secondary microseism band shows a seasonal variation for each station, with the highest power level we can find on the winter season with a peak in February, however the lowest power we could see on summer with a peak in July or August. We classify the PSD level for each station into four clusters, one cluster for the secondary microseism band has a peak at 5 second, and the other clusters have a maximum value of 4 -5 second. The primary microseism level for all the clusters have a similar pattern with the highest value at 15 seconds. The short period band for every cluster has a different level with the period at 0.3 – 0.4 second where cluster 1 has -152 dB, cluster 2 has – 138 dB, cluster 3 has -145 dB and cluster 4 has -123 dB, respectively. As we can see the period (3 – 10 s) band is related to the climate system in Greenland, almost all the stations at cluster 1 located in arctic climate zone and the other clusters located in sub-arctic climate zone. We found that all seismic stations which are located in the central part of Greenland, it showed two peaks of secondary microseism almost the whole year. On the other hand, most seismic stations located on the east and west part showed the two peaks of secondary microseism only for two until four months. This means the stations located in central part of Greenland has a different source of secondary microseism for a whole year. Due to this problem, the investigation was conducted to study the factors which work on secondary microseism in Greenland, including the location of the source of secondary microseism band. This study will also learn the connection between microseism band and climate systems in Greenland.

Testo completoDuring the month of July 1987 an acoustical experiment was conducted by the United States Naval Research Laboratory (NRL) in the East Greenland Sea Marginal Ice Zone (MIZ) . Ambient noise "hot spots" or concentrated areas of relatively high noise levels were found along the ice edge using a towed array. Ambient noise levels were obtained on 27 and 28 July using AN/SSQ-57A and AN/SSQ-57XN5 calibrated sonobuoys . The temperature structure of the area was determined using XBT (ship) and AXBT (P3C aircraft) buoys placed inside and outside the ice edge. The ice edge was determined from coincident satellite photos, 90 GHz microwave imagery and P3 radar ice edge maps. Weather data (sea state and wind speed and direction) were recorded on the ship. The data seem to indicate a correlation between the high ambient noise levels of the hot spots and the presence of a large topographically controlled mesoscale eddy located at the southeastern extent of the MIZ.
