Research Cruise M151 - ATHENA. From the 6.October to the 31. October 2018 the RV Meteor explored the slopes of the Azores and its southwestern seamounts, including Great Meteor Seamount, as part of the ATHENA research project. A scientific team composed of marine biologists, geologists, and environmental physicists were on board to collect seawater, sediment and fossil cold-water corals
Preliminary paleoecological reconstruction of long-term
6/1/2016 · It is possible that cool mixed forest steppe dominance was appeared during the Upper Palaeolithic and cool mixed forest dominance was formed in the Epipalaeolithic. The radiocarbon ages cannot show the change of these horizons but it is possible that the process passed off during 13,000 cal BP (11,000 cal BC) years similarly to other data [82, 83].

Results indicate that fire regime follows the Dansgaard-Oeschger climatic variability and its impacts on fuel load. No major disturbance in natural fire regime variability is observed at the time of the arrival of Modern Humans in Europe or during the remainder of the Upper Palaeolithic (40–10 kyr cal BP).

The lower forest subzone on the west -facing slopes of the southern Barguzin Range (456-600 m a.s.l.) comprises larch forests and pine scrubs (Pinus pumila) (Fig. 2A). Scots pine prevails in the subzone of mixed taiga forest (600 -850 m). In the upper forest subzone (850 and 1150 m) the forest c ommunities are formed by Siberian pine

Radiocarbon dating was performed on marine organisms sampled from 10 representative boulders in all the sites. Moreover, three dating samples provided by Biolchi et al. (2016) were recalibrated (Table 4; Fig. 8). Four samples support the hypothesis of recent strong storm events, dating back to post AD 1954.

Metamorphic rocks can, occasionally, be dated, and this may give some limits to the age at which a bed could be laid down. For example, if a bed containing graptolites overlies crystalline basement at some point, dating the crystalline basement will give a maximum age of that fossil assemblage.

The outcome of this speculative analysis is that, based on radiocarbon evidence, Thera could be related to any one of the five volcanoes that have left evidence in ice core and tree ring records between 1650 B. C. and 1595 B. C. With the exception of the GISP2 1623 B.C. layer, none of the others have been searched for tephra from Thera.

Radiocarbon ages on handpicked foraminifera from deep-sea cores are reveal- ing that areas of rapid sediment accumulation are in some cases subject to hiatuses, reworking and perhaps secondary calcite deposition. We present here an extreme example of the impacts of such disturbances.

Radiocarbon Dating. C-14 is made by the interaction of cosmic rays with nitrogen in the upper atmosphere. The radioactive carbon quickly bonds with atmospheric oxygen to form carbon dioxide, which is absorbed by green growing plants during photosynthesis.

The preparation of ice samples follows the procedure according to Jenk et al. (2007). First, samples are decontaminated in a cold room (-20 ∘ C) by removing the outer layer (3 mm) with a pre-cleaned stainless steel band saw (wiped 3 times with acetone, followed by multiple cuts through a frozen block of ultra-pure water, 18 M Ω cm quality), followed by rinsing the samples with ultra-pure
