We report here the genome sequence of an ancient human. Obtained from ∼4,000-year-old permafrost-preserved hair, represents a male individual first known culture to settle in Greenland. Sequenced average depth 20×, we recover 79% diploid genome, amount close practical limit current sequencing technologies. identify 353,151 high-confidence single-nucleotide polymorphisms (SNPs), which 6.8% have not been reported previously. estimate raw read contamination be no higher than 0.8%. use...
The New World Arctic, the last region of Americas to be populated by humans, has a relatively well-researched archaeology, but an understanding its genetic history is lacking. We present genome-wide sequence data from ancient and present-day humans Greenland, Arctic Canada, Alaska, Aleutian Islands, Siberia. show that Paleo-Eskimos (~3000 BCE 1300 CE) represent migration pulse into independent both Native American Inuit expansions. Furthermore, continuity characterizing Paleo-Eskimo period...
The Paleo-Eskimo Saqqaq and Independence I cultures, documented from archaeological remains in Northern Canada Greenland, represent the earliest human expansion into New World's northern extremes. However, their origin genetic relationship to later cultures are unknown. We sequenced a mitochondrial genome by using 3400-to 4500-year-old frozen hair excavated an early Greenlandic settlement. sample is distinct modern Native Americans Neo-Eskimos, falling within haplogroup D2a1, group...
Mercury concentrations in hair from 397 Greenland polar bears (Ursus maritimus) sampled between 1892 and 2001 were analyzed for temporal trends. In East the showed a significant (p < 0.0001, n = 27) increase of 3.1%/year period 1892−1973. Northwest Greenland, similar 69) 2.1%/year was found, which continued until 1991, when most recent samples obtained. 0.009, 322) decrease 0.8%/year observed after 1973.

Abstract The 15th century Inuit mummies excavated at Qilakitsoq in Greenland 1978 were exceptionally well preserved and represent the largest find of naturally mummified specimens from Arctic. estimated ages individuals, their distribution between two adjacent graves, results tissue typing, incomplete STR led researchers to conclude that eight formed distinct family groups: A grandmother (I/5), daughters (I/3, I/4), children (I/1, I/2) one grave, sisters (II/6, II/8) a daughter (II/7) them...
The examination of Norse farm sites in Greenland has been taking place for nearly a century, and reasonable picture built up from several disciplines the nature settlements. There has, however, little integration research between various scientists. Using example recent interdisciplinary palaeoecological study at Nipáitsoq Western Settlement, this paper summarizes interrelated results work an archaeologist (C.A.), historian (G.S.), animal bone specialist (T. McG.), entomologists (P.C.B. &...
The plasmasphere (also denoted as the protonosphere) is a large toroidal domain of light ionized particles situated above ionosphere and confined by Earth's magnetic field. While plasmaspheric charge densities are considerably less than those ionosphere, extent can produce significant column densities, or total electron content (TEC), for lines‐of‐sight passing through plasmasphere. A method Self‐Calibration Range Errors (SCORE) has been developed previously both to determine combined bias...
Northwest Greenland formerly supported a population of musk-ox ( Ovibos moschatus ). Radiocarbon dating remains collected on the terrain surface and from archaeological sites has yielded Late Holocene ages, indicating that species was late immigrant to this part Greenland. Musk-ox arrived at time when uninhabited, had least several hundred years expand spread south, before Dorset people began hunt. The main reason did not disperse south West probably because barrier presented by Melville...
Northeast Greenland supports a large indigenous population of musk-oxen ( Ovibos moschatus ). Radiocarbon dating remains this mammal collected on the terrain surface and from archaeological sites has yielded mid- Late Holocene ages. The species probably arrived shortly before part became inhabited by first hunter cultures. Only dates are available southern northeast Greenland, but authors suggest that musk-ox spread south to region at an early date, because there no physical barriers. lack...
The recent mass loss of the Greenland ice sheet (Chen et al. 2006), observed increases in velocity its fast-flowing outlets (Luthcke 2006) and melting permafrost demonstrate profound changes occurring Arctic region as a result global warming (ACIA 2005). This is corroborated by systematic satellite monitoring that shows there has been progressive decrease extent sea over last 30 years, with record low 2007 (Comiso 2008). Forward modelling predicts accelerated rates sea-ice disintegration...
To reveal prehistoric behaviours and modes of conduct from an archaeological assemblage it is necessary to employ more encompassing methodological approaches that bring people's acts thoughts into focus. The following study investigates the lithic assemblage, a fully excavated multiple dwelling site High Arctic Greenland, in attempt demonstrate application chaîne opératoire, with emphasis on problem-oriented refitting, can produce unexpected often surprising outcomes. Furthermore, this...
ABSTRACT Radiocarbon age determinations of 32 walrus ( Odobenus rosmarus ) remains show that the species has been a member Greenland fauna since at least middle Holocene. The oldest date is 7280–7160 calendar years BP. However, most dated come from archaeological sites and are late Holocene
Coal petrographic techniques have been used to trace the origin of coal produce artifacts by Thule people in north-eastern Greenland. The were collected from north-east coast settlements between 76°55'–80°18'N and date back 15th century A.D. data suggest that they a common source, Middle Jurassic coals outcropping south 75°15' It is thus evident local material rather than bringing known “mines” Arctic Canada. also implies contemporaneous groups along east Greenland contact traded.
In Greenland, Palaeoeskimo dwellings are mostly concentrated in the north and northeast parts of island. Some found southeast, west (from Nuuk to Disko Bay), northwest (Inglefield Land Washington Land). During entire period, show an emphasis on axial element. Early period (Saqqaq Independence I) fireplace is a separate square box inside two parallel rows flags or boulders. Cooking and/or seething stones common during Saqqaq rare Dorset. Late Saqqaq, shift dwelling style platform-like...
