“…Typical of hard-water lakes, Zaca Lake undergoes frequent whitings in late spring and summer, during which carbonate compounds precipitate (Koschel et al 1983;Murphy et al 1983;Vanderploeg et al 1987). Zaca Lake whitings contribute substantially to light extinction and have large effects on TN : TP in the euphotic zone (see results).…”

Daphnia manipulation in large enclosures, and whole-lake observations before and after a fishkill, showed that intense Daphnia grazing produces large elevations in particulate N : P ratios (PN : PP) during clear-water periods in a eutrophic lake. The direction of this effect was consistent with expected taxonomic variation among zooplankton in the N : P of excretion.N and P sedimentation (mg m-2 d-l) was reduced during Daphnia-induced, clear-water periods, despite increases in particle sinking velocities. In addition, there was an unexpected difference between seston N : P and the N : P of settled particles during clear water, resulting in a d@zrential increase in average sinking velocity calculated for PP relative to PN.Daphnia effects on N: P later in the season appeared to be opposite to those during clear water. My data suggest that Daphnia grazing can reduce carbonate precipitation (whitings) by controlling algal biomass. Whitings were accompanied by large increases in sedimentary loss rates for total P (TP) and elevated TN: TP in the euphotic zone. Thus, Daphnia grazing may maintain relatively low TN : TP during summer in eutrophic, hard-water lakes.

“…Precipitation of carbonate compounds is commonly associated with increased algal 'uptake of carbon and resultant elevation of pH (Koschel et al 1983;Murphy et al 1983;Vanderploeg et al 1987). In Zaca Lake, the whiting period in both years began only after algal biomass began to increase after the clear-water phase (Fig.…”

“…Our bi-weekly sampling probably prevented full resolution of its occurrence within the individual years. Whiting has been linked to increases in primary production, temperature, or both (Vanderploeg et al 1987;Homa and Chapra 2011). Nucleation sites that kinetically promote the precipitation are critical (Homa and Chapra 2011).…”

The dynamics of light scattering by minerogenic particles in the upper waters of Cayuga Lake, New York, were characterized for the spring-autumn interval of 8 yr (1999)(2000)(2001)(2002)(2003)(2004)(2005)(2006) at pelagic and nearshore sites with a scanning electron microscope interfaced with automated image and x-ray analyses (SAX). SAX results were used to estimate the minerogenic scattering coefficient ( Light scattering by particles, a fundamental process regulating radiative transfer in water (Kirk 2011), is important in determining apparent optical properties (AOPs, depend on geometry of the light field) of interest, including clarity (Preisendorfer 1986) and the remote sensing signal (Woźniak and Stramski 2004). The total scattering coefficient (b; m 21 ), corresponding to the integration of the volume-scattering function over all directions (Kirk 2011), quantifies a central feature of the light-scattering regime. b is an inherent optical property, independent of the geometry of the light field. The magnitude and spectral features of the particulate component of scattering, b p (which greatly exceeds that due to water), depend on multiple attributes of a particle population, including the number concentration (N), the particle size distribution (PSD), the composition of the individual particles and their shapes (Babin et al. 2003).The particle populations of aquatic ecosystems are heterogeneous, varying in time and space and differing greatly among systems in response to an array of drivers (Stramski et al. , 2007Peng and Effler 2011). Protocols for resolving the various components of light scattering are needed to understand these differences and dynamics, and to identify their origins and drivers, objectives that are consistent with the reductionist approach advocated by Stramski and co-workers (Stramski et al. 2001(Stramski et al. , 2007 where V is the sample volume, N m is the number of minerogenic particles in a sampled volume of water, and PA m,i is the projected area (m 2 ) of minerogenic particle i. Q bm,i depends on the complex refractive index (m i , function of composition) and size (d i ) of the particle, and the wavelength of light (l). This SAX-Mie approach supports further partitioning of b m into contributions according to size and particularly composition (e.g., clay minerals, quartz, and calcite) of particles Effler 2010, 2011). Early research with the SAX-Mie approach had appropriately focused first on testing the credibility of the forward estimates of b m for a range of particle assemblage conditions (see

“…No study has yet examined whether mineral ballast reduces the rate of remineralization driven by grazing by marine zooplankton, especially with respect to aggregates, although suspended particles of clay and calcite are known to interfere with feeding by Daphnia sp. in freshwater systems (Vanderploeg et al, 1987;Kirk, 1991).…”

Enhanced rates of particulate organic matter remineralization by microzooplankton are diminished by added ballast minerals

et al. 2013

To examine the potentially competing influences of microzooplankton and calcite mineral ballast on organic matter remineralization, we incubated diatoms in darkness in rolling tanks with and without added calcite minerals (coccoliths) and microzooplankton (rotifers). Concentrations of particulate organic matter (POM in suspension or in aggregates), of dissolved organic matter (DOM), and of dissolved inorganic nutrients were monitored over 8 days. The presence of rotifers enhanced the remineralization of ammonium and phosphate, but not dissolved silicon, from the biogenic particulate matter, up to 40% of which became incorporated into aggregates early in the experiment. Added calcite resulted in rates of excretion of ammonium and phosphate by rotifers that were depressed by 67% and 36%, respectively, demonstrating the potential for minerals to inhibit the destruction of POM by zooplankton in the water column. Lastly, the presence of the rotifers and added calcite minerals resulted in a more rapid initial rate of aggregation, although not a greater overall amount of aggregation during the experiment
