In open ocean applications, faster-dissolving minerals can be used for OAE if they dissolve sufficiently rapidly before sinking below the mixed layer.
“In open ocean applications, faster-dissolving minerals can be used for OAE if they dissolve sufficiently rapidly before sinking below the mixed layer. 23”
From A framework for understanding efficiency losses of Ocean Alkalinity Enhancement (2026) · cites this paper as [23]
The Introduction (page unavailable) says ikaite crystals smaller than 300 μm will dissolve within the ocean mixed layer and could contribute to CO2 removal. That supports the claim for ikaite, but the passage does not establish the broader claim about faster-dissolving minerals generally or explicitly discuss dissolution before particles sink below the mixed layer.

About these checks
Registry, retraction, Cites and statistics results are computed, not judged, with one exception: a printed reference that no index lists is read once by a model before it counts as a citation error. Claims are extracted by a model and kept only when their quote appears verbatim in the text; each cited source is then checked, with a model’s help, for whether it says what the claim relies on. Those verdicts can be wrong — read the claim’s quote and the cited source before relying on one.
Statistics and arithmetic are recomputed, not judged.
Confidence bands are shown only for fields calibrated on our annotated test set. None is calibrated yet, so no band is shown.
