Sediment focusing in Mirror Lake, New Hampshire1
Open accessAbstract
Analyses of multiple sediment cores from Mirror Lake, New Hampshire, dated by 14C and pollen, show that between 14,000 and 11,000 b.p. silts and sands were deposited over 85% of the basin. After 11,000 b.p. organic-rich sediments were focused into the deeper parts of the basin, and no sediment accumulated in water <5 m deep. Late-glacial particulate inorganic inputs were 33 times greater than modern losses from forested watersheds at Hubbard Brook. After trees became established, inorganic inputs fell sharply to modern levels. Late-glacial organic inputs were a half the average during the last 11,000 years. At four of the sites studied, accumulation rates reached a maximum between 7000 and 4000 b.p. The precise date varies from site to site, suggesting that it would be misleading to link peak accumulation in a single core to events in the watershed. After 4000 b.p. organic sediment accumulation rates declined at all four sites. Parallel declines in accumulation rates of both pollen and inorganic sediments suggest that this decline is due to the process of sediment focusing rather than to a change in decomposition rates or in organic inputs related to autochthonous or allochthonous primary production.

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.
