Determination of the regimes of production in the Antarctic sea-ice during SIPEX 2 using Si, N, and C stable isotope in-situ incubation experiments and 13C and 14C primary production method intercomparison
Overview of the project and objectives: Assessing the contribution of the different N substrates to the primary production process, such as the biogenic silica production and dissolution in the Antarctic sea-ice provides a means to understand the biogeochemical system functioning. In such a semi clo...
