Concentration of the radio nuclide beryllium-7, produced by cosmic rays, was measured in waters collected from both the Atlantic and Pacific oceans. This short-lived nuclide is well suited as a tracer for interactions at the air-sea interface and for the measurement of rapid mixing processes in the surface layer of the ocean. 

Measurements of the distribution and behaviour of Beryllium-7 in the natural environment

Beryllium-7 is a cosmogenic radionuclide produced in the atmosphere through the spallation of nitrogen and oxygen nuclei by cosmic-ray-produced neutrons and protons. It is carried in the atmosphere

Oceanic Residence Times of Dissolved Beryllium and Aluminum Deduced from Cosmogenic Tracers 10Be and 26Al

The residence times of the soluble fractions of beryllium and aluminum in seawater are estimated to be 1500 years or more, which are greater by an order of magnitude than the mean residence times and the concentrations of these radionuclides in seaw water estimated from the specific activities of these Radionuclide in an authigenic mineral assembly such as a manganese nodule.

Chapter 5 Meteoric 7 Be and 10 Be as Process Tracers in the Environment

Be (T1/2 1⁄4 53 days) and Be (T1/2 1⁄4 1.4 Ma) form via natural cosmogenic reactions in the atmosphere and are delivered to Earth’s surface by wet and dry deposition. The distinct source term and

210Pb and 7Be as Coupled Flux and Source Tracers for Aerosols in the Pacific Ocean

Deposition of aerosols to the surface ocean is an important factor affecting primary production in the surface ocean. However, the sources and fluxes of aerosols and associated trace elements remain

APPLICATION OF SHORT-LIVED COSMOGENIC RADIONUCLIDES AS TRACERS OF IN-CLOUD SCAVENGING PROCESSES.

Measurements of the cosmogenic radionuclides 38Cl (37.3 min half-life), 39Cl (55 min), and 24Na (15 hours) in consecutive rain water samples during storms have provided a basis for studying

Numerical simulation of the intra-annual evolution of beryllium-7 (7Ве) in the surface layer of the Black Sea

It was revealed that the adsorption of 7Ве on suspended matter is most significant for the evolution of the content of this radionuclide in shelf waters.

It was revealed that variation of both 7Be wet deposition on the sea surface and concentration of suspended matter were the most significant for spatiotemporal variability of 7Be activity in seawater during the study period.
