    Abstract
    The Oxygen Minimum Zone (OMZ) is a potential source of CO<sup>2</sup> to the atmosphere, and the extensive OMZ spread to 1.37 × 10<sup>6</sup> km<sup>2</sup> in the Northern Arabian Sea would be an important contributor to the CO<sup>2</sup> budget. In this perspective, we report here that the Eastern Arabian Sea experienced coeval increase in productivity and denitrification from ~7 to 0 kyr, which coincides with minimum dissolved oxygen levels in bottom waters. In addition, during the same period, an increased calcium carbonate dissolution occurred as evidenced by low CaCO<sup>3</sup> content, decreasing shell weights of planktonic foraminifer species Globigerinoides ruber with well-marked dissolution features on their shells. Therefore, this study has implications on the role of OMZ in governing CaCO<sup>3</sup> dissolution and contributing to an increase in atmospheric CO<sup>2</sup>.
