Extraterrestrial dust as a source of bioavailable iron contributing to the ocean for driving primary productivity
Rudraswami, N.G.; Pandey, M.; Genge, M.J.; Fernandes, D. (Wiley, 2021)Bioavailable Fe is an essential nutrient for phytoplankton that enables the organisms to flourish and draw down atmospheric CO2 thus affecting global climatic conditions. In marine locales, remote from the continents, ... -
Geochemical evaluation of cosmic spherules collected from the Central Indian Ocean Basin
Pandey, M.; Rudraswami, N.G.; Singh, Vijay; Viegas, A. (Elsevier, 2023)Micrometeorites (MMs) significantly contribute to the extraterrestrial material the Earth receives and represent a broader range of precursors than known meteorites. Low sedimentation rates prevalent in the deep-sea regions ... -
Geochemistry of aerodynamically distorted Australasian microtektites: Implications for ejecta on Mars and Venus
Rudraswami, N.G.; Prasad, M.S.; Iyer, S.D.; Pandey, M.; Helo, C.; Panda, D.K. (Springer, 2021)We report microtektites recovered from a large area of the deep seafloor (Central Indian Ocean) that appear to have undergone aerodynamic distortion during re-entry into the atmosphere. Considering the geographic locations, ... -
Glass spherules from Antarctica blue ice and deep-sea sediment of the Central Indian Ocean Basin
Fernandes, Dafilgo; Rudraswami, N.G.; Pandey, M.; Kotha, M. (Springer, 2021)We report the chemical composition of 176 glass spherules obtained from Antarctica blue ice and deep-sea sediments from the Central Indian Ocean Basin. This study compares the chemistry of glass spherules collected from ... -
Oxygen Ablation during Atmospheric Entry: Its Influence on the Isotopic Composition of Micrometeorites
Rudraswami, N.G.; Pandey, M.; Fernandes, D.; Carrillo-Sanchez, J.D.; Feng, W.; Plane, J.M.C.; Singh, Vijay (IOP Publishing, 2022)Micrometeorites (MMs) offer glimpses of the diverse nature of parent bodies that accreted during the first few million years after the formation of the proto-Sun.The present work explores this by evaluating the ablation ... -
Probing the nature of extraterrestrial dust reaching the Earth�s surface collected from the Maitri station, Antarctica
Rudraswami, N.G.; Fernandes, Dafilgo; Pandey, M. (University of Arkansa, 2020)Micrometeorites (MMs) are extraterrestrial dust particles, in the size range of tens of �m to mm, recovered from the Earth�s surface primarily from deep-sea sediments, Antarctica, and also from space. The present collection ...
