Ammonium adsorption in marine sediments1
Open accessAbstract
One important reaction which affects dissolved NH 4+ distributions in marine sediments is reversible adsorption on sediment solids. We investigate both the temperature dependency and spatial variability of the NH 4+ linear adsorption coefficient, K, in marine sediments. For a wide range of environments, because of approximately offsetting variations in sediment porosity and properties such as clay mineral and organic matter content, K is nearly constant (1.3 ± 0.1) in terrigenous, surface, marine sediments. The value of K also does not vary significantly as a function of temperature. In biogenic and very high porosity (≳0.95) sediments K may be somewhat lower than for other sedimentary environments. Sediments containing seagrass detritus such as Thalassia may be expected to exhibit relatively high K values.

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.
