variations are similar to that of Antarctic lakes, sub-ice . shelf/continental shelf, or an open marine environment (Fig. 1A, Table 2). Determining which environment the Adelie Basin is similar to may aid in assessing which mechanisms affect beryllium isotope varia- tions in the Adelie Basin during the Holocene. We compare our data to

Naturally Occurring Beryllium Isotopes. Beryllium-9 is the only stable isotope found on earth. The smallest traces of the radioactive nuclides 7 Be and 10 Be can be detected as radioisotopes of cosmic origin. The beryllium-11 atom is one of the so-called halo nuclei; it consists of 4 protons and 6 neutrons in the nucleus and a weakly bound ...

A spectral analysis of data on the flux of cosmogenic 10Be in ice core samples from the Central Greenland (project GRIP) over the last 10 thousand years have been carried out. It has been shown that the 10Be flux varies cyclically; the most significant cycle is of about 2300 years. Variations in the position of the virtual geomagnetic pole …

Beryllium isotope records reveal melting of local glaciers associated with higher subglacial erosion between ∼4.1 and ∼3.6 ka BP. Comparison to marine records from the Antarctic continental shelf suggests this was part of a circum-Antarctic phenomena that led to widespread glacial discharge from other sectors of the East and West …
In contrast, changes in 10 Be/ 9 Be ratio caused by small variations in the input of 9 Be might be unresolvable within the precision of the time-corrected ratios. Further evidence for changes in terrigenous input is provided by new Nd isotope data from both planktonic foraminifera and also bulk sediment from the Labrador Sea [45].

There are a few studies on the application of the beryllium isotopes to understand the processes governing the distribution of 10Be from the Indian Ocean. However, limited attempts were made to understand the spatial distribution of beryllium isotopes (Bourles et al., 1989; von Blanckenburg et al., 1996) and temporal variation in …

Their co-variation dictates that excess 50V and 10Be were synthesized through irradiation of refractory dust. Modelling of the production rate of 50V and 10Be demonstrates that the dust was exposed to solar cosmic rays produced by gradual flares for less than 300 years at ≈0.1 au from the protosun. ...

The direct measurement of the ratio of cosmogenic 10Be (T1/2 = 1.5 Ma) to stable terrigenously sourced 9Be in deep seawater or marine deposits can be used to trace water mass movements and to quantify the incorporation of trace metals into the deep sea. In this study a SIMS-based technique has been used to determine the 10Be/9Be ratios of the ...

Protons. A proton is one of three main particles that make up the atom. Protons are found in the nucleus of the atom. This is a tiny, dense region at the center of the atom. Protons have a positive electrical charge of one ( + 1) and a mass of 1 atomic mass unit (amu), which is about 1.67 × 10 − 27 kilograms.
Here we report quasi-weekly data on 10 Be and 7 Be isotopes covering the periods 1983-2000 and 1975-2006 respectively, that show, for the first time, coherent variations reflecting both atmospheric and production effects.

Beryllium-10 is a long-lived radioisotope of the chemical element Beryllium, which, in addition to the element-specific 4 protons, has 6 neutrons in the atomic nucleus, resulting in the mass number 10. 10 Be is the most stable representative of the radioactive Be isotopes with a half-life of 1.387 million years. It is formed in the Earth's atmosphere mainly …
