Changes in Deposition of Phytoplankton Constituents in a Ca2+Polluted Lake
Abstract
Systematic reductions in the deposition rate of organic C, N, P, and chlorophyll (Chl) are documented for Ca2+ polluted, culturally eutrophic, Onondaga Lake, NY, based on analyses of weekly sediment trap collections over the May-October interval for 10 years of the 1980-1992 period. Inputs of both nutrient-rich domestic waste and industrial salt waste (including Ca2+) decreased over this period. Constituent ratios of the collected sediment indicate phytoplankton biomass was the dominant source of the deposited organic C, N, and Chl. Substantial decreases in downward fluxes of these constituents occurred starting in 1987: 37, 42, 25, and 54%, on average, for organic C, N, P, and Chl, respectively. These reductions were driven primarily by the decreases in the lake's salinity and Ca2+ concentration, that resulted from the closure of a soda ash manufacturing facility (1986), rather than decreases in water column P concentrations from reductions in domestic waste loading. Three different mechanisms for the decreased deposition, related to the reductions in salinity and Ca2+ concentration, are considered: (i) decrease in coating of phytoplankton with CaCO3 precipitate, (ii) increased grazing of phytoplankton by large cladocerans, and (iii) decreases in coagulation of phytoplankton. The greater loss of phytoplankton biomass through deposition, driven by salt waste inputs from the industry, exacerbated the lake's problem of high primary production. This response is consistent with e…

High calcium concentrations increased deposition losses of particles (including phytoplankton) from the trophogenic layers of Onondaga Lake.
“and thus increased deposition losses of particles (including phytoplankton) from the trophogenic layers (Effler et al. 2001;Effler and Matthews 2003).”

The closure of the soda ash industry in Onondaga Lake in 1986 resulted in an abrupt decrease in organic carbon deposition, which was likely associated with a similar decrease in primary production.
“The closure of an industry in 1986 resulted in an abrupt decrease in organic carbon deposition that was likely associated with a similar decrease in primary production (Effler et al. 2001(Effler et al. , 2005)).”

The 61% decrease in salinity was accompanied by a 65% decrease in ionic calcium concentration.
“This 61% decrease in S was accompanied by a 65% decrease in [Ca 2+ ] (Effler et al. 2001).”

The leading explanation for the decrease in particulate organic carbon deposition is reduced coagulation and rate of deposition of phytoplankton associated with the decreased calcium concentration.
“The leading explanation for the decrease in POC df is reduced coagulation and rate of deposition of phytoplankton associated with the decreased Ca 2+ concentration (Effler et al. 2001).”

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.
