Abstract

Long‐term trends in the rate of depletion of hypolimnetic dissolved oxygen (DO) are documented for ionically enriched hypereutrophic Onondaga Lake, New York, for the 1978–2002 interval. Depletion rates, represented as areal hypolimnetic oxygen deficits (AHOD, g m−2 d−1), are calculated on the basis of weekly DO profiles of 1‐m resolution and estimates of coincident inputs of DO from overlying layers driven by vertical mixing. Vertical mixing inputs of DO are important in this system, representing from 15% to 37% (mean 25%) of AHOD. Interannual variations in hypolimnetic temperatures have comparatively minor (±6%) effects on AHOD. AHOD decreased 49%, from an average of 2.12 g m−2 d−1 for the 1978–1986 interval, to an average of 1.08 g m−2 d−1 for the 1997–2002 interval. This decrease was driven by an abrupt decrease in the deposition of particulate organic carbon into the hypolimnion starting in 1987. The magnitude of the decrease in AHOD closes reasonably well with decreases in both primary production in the trophogenic zone and organic carbon deposition to the tropholytic zone. The time course of the decrease in AHOD is consistent with localization of oxygen‐demanding processes within the lake sediments, reflecting the progression of sediment diagenesis.

  • Hypolimnetic anoxia eliminated the year-round availability of coldwater habitats in Onondaga Lake; however, dissolved oxygen conditions were sufficient to support seasonal use for coldwater species using the lake as part of their regional, annual home range.

  • In lakes with a long history of eutrophy (i.e., a large pool of unmineralized organics in the sediments), the time to reach a new steady-state hypolimnetic dissolved oxygen depletion rate may be on the order of years to decades.

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.
