| Summary: | Introduction: This study aims to elucidate the role of dissolved calcium (Ca) and potential alkalinity (PA) as tracers for calcium carbonate (CaCO3) cycling in the Southern Ocean. Understanding the dynamics of these key chemical components contributes to a broader comprehension of oceanic carbon cycling and its potential implications for marine ecosystems. Sampling Sites: Samples were collected in the Australian sector of the Southern Ocean during R/V Investigator voyage IN2020_V08, conducted between 4 December 2020 and 15 January 2021. Samples were collected at three primary sites: the Southern Ocean Time Series (SOTS) site (47°S, 141°E), and two southern sites (SS1 and SS2) located within a polar bloom at approximately 55°S, 138°E, and 58°S, 141°E, respectively. Sampling Methodology: Samples were collected using CTD rosettes at various depths to capture vertical profiles of Ca and total alkalinity (TA). The choice of depth range is crucial for understanding the vertical distribution of these tracers. ... |
