Dating religious change
Mortuary customs frequently provide the principal archaeological evidence for religious identity. Such customs are often seen as a direct reflection of religion and therefore a change of religion should be expected to result in a change in burial rite. There is growing evidence that the relationship is not so straightforward. In this paper we report results from Viking Age Iceland which challenge the previous view of a relatively clear-cut transi…
The Settlement Date of Iceland Revisited
The settlement time of Iceland has been debated for years as radiocarbon dates of bulk wood samples have been interpreted to set a timing 150–200 yr earlier than indicated by tephrochronology (later than AD 871±2) and the Sagas (AD 874). This early date is also in conflict with the dating results on extensive series of short-lived material such as grain and domestic animal and human bone remains of early settlers. The old-wood effect for the char…
Norse Greenland Dietary Economy ca. AD 980-ca. AD 1450
An initial study of the 13 C values for human bone collagen of 27 Norse Greenlanders in the late 1990s suggested a change in the Norse diet from predominantly terrestrial to predominantly marine food. This shift may well indicate a change in diet; the question left open by the limited initial isotope study was, however, whether the change in diet was a reflection of altered subsistence strategies or altered farming practices. Furthermore, the fir…
An Isotopic Analysis of the Diet of the Greenland Norse
Our understanding of the Norse dietary adaptations to their Greenlandic home comes primarily from sparse historical records, from what is known of the Norse dietary economy in other North Atlantic lands, and from zooarchaeological examinations of the animal bones found in the various excavations of Norse Greenlandic sites which have taken place over the past century. To obtain more detailed information on the diets of the Norse settlers in Greenl…
Successful AMS 14 C Dating of Non-Hydraulic Lime Mortars from the Medieval Churches of the Åland Islands, Finland
Fifteen years of research on accelerator mass spectrometry (AMS) radiocarbon dating of non-hydraulic mortar has now led to the establishment of a chronology for the medieval stone churches of the Åland Islands (Finland), where no contemporary written records could shed light on the first building phases. In contrast to other material for dating, well-preserved mortar is abundantly available from every building stage. We have gathered experience f…
High-Resolution Greenland Ice Core Data Show Abrupt Climate Change Happens in Few Years
The last two abrupt warmings at the onset of our present warm interglacial period, interrupted by the Younger Dryas cooling event, were investigated at high temporal resolution from the North Greenland Ice Core Project ice core. The deuterium excess, a proxy of Greenland precipitation moisture source, switched mode within 1 to 3 years over these transitions and initiated a more gradual change (over 50 years) of the Greenland air temperature, as r…

C Dating of the Settlement of Iceland
The dating of the settlement of Iceland has been debated for many years. According to written sources (sagas) from the early 12th century, the first Norwegian settlers arrived in Iceland in AD 874. However, some 14 C dates from the earliest archaeological sites in Iceland, invariably from samples of birch and other indigenous wood species, have yielded surprisingly old ages, older by 100–150 yr than the historical date, suggesting that the settle…
Oxygen isotope and palaeotemperature records from six Greenland ice‐core stations
Oxygen isotope variations spanning the last glacial cycle and the Holocene derived from ice‐core records for six sites in Greenland (Camp Century, Dye‐3, GRIP, GISP2, Renland and NorthGRIP) show strong similarities. This suggests that the dominant influence on oxygen isotope variations reflected in the ice‐sheet records was regional climatic change. Differences in detail between the records probably reflect the effects of basal deformation in the…
Change of Diet of the Greenland Vikings Determined from Stable Carbon Isotope Analysis and 14 C Dating of Their Bones
Bone samples from the Greenland Viking colony provide us with a unique opportunity to test and use 14 C dating of remains of humans who depended upon food of mixed marine and terrestrial origin. We investigated the skeletons of 27 Greenland Norse people excavated from churchyard burials from the late 10th to the middle 15th century. The stable carbon isotopic composition (δ 13 C) of the bone collagen reveals that the diet of the Greenland Norse c…
C AMS Dating of Icelandic Lake Sediments
We report an age-depth profile for the sediments of the Lake Hesrvatn, southern Iceland, based on 14 C analyses of the organic fraction of bulk sediment samples, molluscs and foraminifera. Our age-depth curve is supported by the occurrence of the well-dated Vedde ash in the lowermost part of the sediments. Comparison of foraminifera dates with the age of the Vedde ash indicates a reservoir age of ca. 400 yr. The results suggest that the sediments…
Origin of 14 C in Icelandic Groundwater
We report the first attempt to date Icelandic groundwater by the radiocarbon dating technique. We propose that boron concentrations of the water samples can be taken as a measure of the amount of dead CO 2 in the groundwater leached from rock. By assuming that the ratio of boron to CO 2 is the same in the rock and groundwater it is possible to correct the 14 C concentration for the contribution of rock-derived carbon in the groundwater and thus c…
Radiocarbon Anomalies Observed for Plants Growing in Icelandic Geothermal Waters
We have studied plant remains in thick beds of lacustrine sediments in the upper part of the Markarfljót drainage area in southern Iceland. We collected small samples of plant species from the same horizon and 14 C dated them at the Aarhus AMS Dating Laboratory. Terrestrial plants yielded an age of 9 ka BP, whereas aquaic moss ( Fontinalis antipyretica Hedw.) yielded the surprisingly old 14 C age of 16 ka bp. We believe the age of the terrestrial…
