      <mri:abstract>
        <gco:CharacterString>These data represent cumulative information on some physical and chemical attributes of terrestrial ponds within the McMurdo Sounds region of Antarctica. Data have been variously published, with most of the contributing to the paper: https://doi.org/10.1007/s00267-021-01438-1. 

The dataset is ongoing, with some analyses pending, and will be kept updated.
