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

2 Overview of radiocarbon calibration 2.1 General principles The term “radiocarbon” is commonly used to denote 14C, an isotope of carbon which is radioactive with a half-life of about 5730years. 14C is produced by cosmic rays in the stratosphere and upper troposphere. It is then distributed throughout the rest of the troposphere, the oceans

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.

Superflare Explained. Superflares are very strong explosions observed on stars with energies up to ten thousand times that of typical solar flares. The stars in this class satisfy conditions which should make them solar analogues, and would be expected to be stable over very long time scales.The original nine candidates were detected by a variety of methods.
