Glacial geology of Thomas Island, Bunger Hills, East Antarctica Open
Thomas Island (Bunger Hills, East Antarctica) is a 34 square kilometre, deglaciated area potentially impacted by the East Antarctic ice sheet and Remenchus Glacier from the east, Shackleton Ice Shelf from the north and Edisto Glacier from …

Holocene environmental history of Thomas Island, Bunger Oasis, East Antarctica, inferred from a lake sediment record Open
Over the last decades, climate change led to only moderate changes of the East Antarctic Ice Sheet (EAIS). In recent years, however, modelling approaches and field experiments have shown that also the EAIS is increasingly affected by ice m…

Findings from an in-Depth Annual Tree-Ring Radiocarbon Intercomparison Open
The radiocarbon ( 14 C) calibration curve so far contains annually resolved data only for a short period of time. With accelerator mass spectrometry (AMS) matching the precision of decay counting, it is now possible to efficiently produce …

Annual radiocarbon record indicates 16th century BCE date for the Thera eruption Open
New annual radiocarbon calibration data offer a resolution to controversial dating of the Bronze Age eruption of Thera.

More Rapid <sup>14</sup>C Excursions in the Tree-Ring Record: A Record of Different Kind of Solar Activity at About 800 BC? Open
Two radiocarbon ( 14 C) excursions are caused by an increase of incoming cosmic rays on a short time scale found in the Late Holocene (AD 774–775 and AD 993–994), which are widely explained as due to extreme solar proton events (SPE). In a…

Fluctuating radiocarbon offsets observed in the southern Levant and implications for archaeological chronology debates Open
Significance We observe a substantive and fluctuating offset in measured radiocarbon ages between plant material growing in the southern Levant versus the standard Northern Hemisphere radiocarbon calibration dataset derived from trees grow…

Radiocarbon Dating and Intercomparison of Some Early Historical Radiocarbon Samples Open
We performed a new series of measurements on samples that were part of early measurements on radiocarbon ( 14 C) dating made in 1948–1949. Our results show generally good agreement to the data published in 1949–1951, despite vast changes i…

Large <sup>14</sup> C excursion in 5480 BC indicates an abnormal sun in the mid-Holocene Open
Significance Carbon-14 contents in tree rings tell us information of the past cosmic ray intensities because cosmic rays produce 14 C in the atmosphere. We found a signature of a quite large increase of incoming cosmic ray intensity in the…

Two radiocarbon excursions (AD 774–775 and AD 993–994) occurred due to an increase of incoming cosmic rays on a short timescale. The most plausible cause of these events is considered to be extreme solar proton events (SPE). It is possible…
