The Minamata Convention, a global and legally binding treaty that entered into force in 2017, aims to protect human health and the environment from harmful mercury (Hg) effects by reducing anthropogenic Hg emissions and environmental levels. The Conference of the Parties is to periodically evaluate the Convention's effectiveness, starting in 2023, using existing monitoring data and observed trends. Monitoring atmospheric Hg levels has been proposed as a key indicator. However, data gaps exist, especially in the Southern Hemisphere. Here, we present over a decade of atmospheric Hg monitoring data at Amsterdam Island (37.80°S, 77.55°E), in the remote southern Indian Ocean. Datasets include gaseous elemental and oxidised Hg species ambient air concentrations from either active/continuous or passive/discrete acquisition methods, and annual total Hg wet deposition fluxes. These datasets are made available to the community to support policy-making and further scientific advancements.
《水俣公约》是一项具有全球约束力的国际公约，于 2017 年生效，旨在通过减少人为汞排放和环境汞水平来保护人类健康和环境免受有害汞影响。缔约方大会应从 2023 年开始，利用现有监测数据和观察到的趋势，定期评估《公约》的有效性。监测大气汞水平已被提议作为一个关键指标。然而，数据空白仍然存在，特别是在南半球。在这里，我们展示了十多年来在遥远的南印度洋阿姆斯特丹岛（南纬 37.80 度，东经 77.55 度）进行的大气汞监测数据。数据集包括气态元素态和氧化态汞物种的环境空气浓度，这些数据来自主动/连续或被动/离散采集方法，以及每年的总汞湿沉降通量。这些数据集提供给社会，以支持决策制定和进一步的科学进步。
