    The advent of Accelerator Mass Spectrometer (AMS) enhanced the application of meteoric 10Be (half-life of 1.39 Ma) as a tracer for understanding earth surface processes on thousand to million-year time scales. However, for ...
  • Saxena, Himanshu; Sahoo, Deepika; Khan, Mohammad Atif; Kumar, Sanjeev; Sudheer, A. K.; Singh, Arvind (IOP Publishing, 2020-05)
    Biological dinitrogen (N2) fixation exerts an important control on oceanic primary production by providing bioavailable form of nitrogen (such as ammonium) to photosynthetic microorganisms. N2 fixation is dominant in ...
  • Sahoo, Deepika; Saxena, Himanshu; Tripathi, Nidhi; Khan, Mohammad Atif; Rahman, Abdur; Kumar, Sanjeev; Sudheer, A. K.; Singh, Arvind (Inter Research, 2020-10)
    Nitrogen (N) and phosphorus (P) determine the strength of the oceans biological carbon (C) pump, and variation in the N:P ratio is key to phytoplankton growth. A fixed C:N:P ratio (106:16:1) in organic matter and deep-water ...
  • Sahoo, Deepika; Saxena, Himanshu; Nazirahmed, Sipai; Kumar, Sanjeev; Sudheer, A. K.; Bhushan, Ravi; Sahay, Arvind; Singh, Arvind (Springer Nature, 2021-07)
    Recent observations and numerical simulations have profoundly established that the C:N:P ratios in the ocean deviate from the canonical Redfield Ratio (106:16:1). Physical and biogeochemical processes have been hypothesized ...
