Sun glint, the specular reflection of light from water surfaces, is a serious confounding factor for remote sensing of water column properties and benthos. This paper reviews current techniques to estimate and remove the glint radiance component from imagery. Methods for processing of ocean color images use statistical sea surface models to predict the glint from the sun and sensor positions an...

The benthos of Lake Creek, Lincoln County, Montana were sampled in 1984-85 to determine the effects of a 2.5 years old tailings impoundment located adjacent to the stream. Sampling results were compared spatially in the 1984-85 data set, and temporally with a baseline data set collected three years prior to installation of the impoundment. Lack of replication in the baseline sampling design pre...

Ocean productivity largely refers to the production of organic matter by “phytoplankton,” plants suspended in the ocean, most of which are single-celled. Phytoplankton are “photoautotrophs,” harvesting light to convert inorganic to organic carbon, and they supply this organic carbon to diverse “heterotrophs,” organisms that obtain their energy solely from the respiration of organic matter. Open...

This study was conducted at the Hanna Reservoir located in the southwest of Isfahan Province. According to this study, chemical analyses were conducted to evaluate the magnitude and variations of COD, BOD5, O2, NH3+ and NO2-concentrations in the Hanna Reservoir. In the headwaters the magnitude values of BOD5, COD and early morning oxygen minima were quite identical to the recommended optimum le...

Abiotic (water quality) and biotic (Phyto-, zooplankton benthos) factors in the Kantivka fattening pond Khmelnitskrybhosp Private Joint-Stock Company were studied during vegetation seasons 2020. The aquaculture objects are cyprinid fish species (carp, grass carp, silver pike). ecological conditions of evaluated as good enough for purpose. critical water quality parameters following traditional ...
