Southern Ocean Ligand (SOLt) Collection

An increasing number of studies are considering Fe and ligand concentrations, providing data of trace element availability across the remote Southern Ocean region (Ardiningsih et al., 2021, Gerringa et al., 2020, Hassler et al., 2017, Thuroczy et al., 2012, Thuroczy et al., 2011, Caprara et al., 2016 and references therein). However, studies seldom focus on polar coastal environments which are especially sensitive to climate-induced changes. To anticipate how these changes may impact Fe availability, we must first understand the drivers of ligand supply to the Antarctic coast and offshore.

The newly compiled Southern Ocean Ligand (SOLt) Collection includes all publicly available Fe complexation datasets for the Southern Ocean including dissolved Fe concentrations, Fe-binding ligand concentrations, and complexation capacities for 25 studies between 1995 - 2019.

越来越多的研究已将铁（Fe）与配体（ligand）浓度纳入考量，提供了偏远南大洋（Southern Ocean）区域的痕量元素有效性相关数据（Ardiningsih等，2021；Gerringa等，2020；Hassler等，2017；Thuroczy等，2012；Thuroczy等，2011；Caprara等，2016及相关参考文献）。然而，目前鲜有研究聚焦于对气候诱导变化尤为敏感的极地沿海环境。若要预判此类变化对铁有效性的影响，我们首先需明确南极海岸及近海的配体供给驱动机制。

新整合的南大洋配体数据集（Southern Ocean Ligand Collection, 简称SOLt）涵盖了南大洋所有公开可用的铁络合数据集，包含1995年至2019年间25项研究的溶解铁浓度、铁结合配体浓度及络合容量数据。
