Short summary
Potential roles of polythionates as key sulfur cycle intermediates are less appreciated, apparently because, in most of the natural environments, they do not accumulate to easily detectable levels. Our exploration of the eastern Arabian Sea sediment horizons revealed microbe-mediated production and redox transformations of tetrathionate to be important modules of the in situ sulfur cycle, even as high biotic and abiotic reactivity of this polythionate keeps it hidden from geochemical detection.
