Modeling cosmogenic radionuclides
All existing 10 Be records from Greenland and Antarctica show increasing concentrations during the Maunder Minimum period (MM), 1645–1715, when solar activity was very low and the climate was colder (little ice age). In detail, however, the 10 Be records deviate from each other. We investigate to what extent climatic changes influence the 5 10 Be measured in ice by modeling this period using th...
متن کاملCosmogenic Radionuclides in Chondrite Shower from Otway
Introduction. In the 2003/04 season, the ANSMET team recovered 83 meteorites in an elliptical area of 1.6 x 0.2 km from a blue ice field near Otway Massif in the Grosvenor Mountains (Fig. 1). The size distribution of the meteorites within this area suggests they are a well preserved strewnfield, with the largest mass (29 kg) on the East end and the smallest masses (~100 g) on the West end [1]. ...
متن کاملInterplanetary magnetic field during the past 9300 years inferred from cosmogenic radionuclides
[1] We have reconstructed the interplanetary magnetic field (IMF), its radial component, and the open solar magnetic flux using the solar modulation potential derived from cosmogenic Be radionuclide data for a period covering the past 9300 years. Reconstructions using the assumption of both constant and variable solar wind speeds yielded closely similar results. During the Maunder Minimum, the ...
متن کاملCosmogenic Radionuclides in Ureilites from Frontier Mountain, Antarctica: Evidence for a Polymict Breccia
Introduction. The Frontier Mountain (FRO) meteorite collection includes 15 small ureilites with masses of 0.5-35 g. The relatively large number of ureilites (compared to only 2 HED meteorites) suggests that many of these specimens are probably part of a single fall. However, the FRO ureilites show several different lithologies with differences in olivine compositions, olivine/pyroxene ratios, s...
