Particle size, percent organic carbon, phosphorus, mineralogy, and deposition of sediments in Ham's and Arbuckle lakes

Abstract

Several sediment parameters were examined in a 40 ha lake with a maximum depth of 9 m and in a 950 ha lake, 26 m deep, from May through October, 1977. Particle size was finer at the deeper stations than at the shallower stations in both lakes. Sediments of the shallow stations generally had a more even grain size distribution. Variation in percent organic carbon and phosphorus among stations of different depths was not significant. However, temporal variation of phosphorus was significant as values increased during summer. Kaolinite was the dominant clay particle in both lakes, but the sediments also included quartz, mica, montmorillonite, and a montmorillonite-vermiculite interlayer. Sedimentation rate was inversely related to depth in the larger lake, while variation among stations in the smaller lake was slight.

Particle size distribution and chemical parameters of the sediments of a shallow turbid impoundment

“…Clay & Wilhm (1979) and Frink (1969) also established a good correlation between water depth and particle size in American lakes. Clay & Wilhm (1979) and Frink (1969) also established a good correlation between water depth and particle size in American lakes.…”

“…Clay & Wilhm (1979) found no correlation between organic matter, depth and particle size in their study of the sediments of Hams and Arbuckle Lakes in Oklahoma. However, in the shallow littoral areas, where an extensive macrophyte vegetation occurs (mainly Phragmites), the sediments were found to have a low organic content.…”

The role of submerged macrophyte beds in phosphorus and sediment accumulation in Lake Memphremagog, Quebec, Canada

“…This finding is particularly relevant because small particles with their large surface area to volume ratio disproportionately sorb P (Clay and Wilhm 1979). An analysis of surficial sediment (0-5 cm) water content allows for a comparison of macrophyte bed sediments with profundal and bare littoral sediments, as water content is an excellent predictor of mean surface sediment particle size (Phi ϭ Ϫ0.93 ϩ 0.09 ϫ water content, r 2 ϭ 0.93; Rowan et al 1992a).…”

“…Submerged macrophytes not only influence sedimentation rates (Benoy and Kalff 1999) but also surficial sediment particle-size distribution, with plant surface area a significant predictor of surface sediment clay content (Petticrew and Kalff 1992). This finding is particularly relevant because small particles with their large surface area to volume ratio disproportionately sorb P (Clay and Wilhm 1979). An analysis of surficial sediment (0-5 cm) water content allows for a comparison of macrophyte bed sediments with profundal and bare littoral sediments, as water content is an excellent predictor of mean surface sediment particle size (Phi ϭ Ϫ0.93 ϩ 0.09 ϫ water content, r 2 ϭ 0.93; Rowan et al 1992a).…”

Distribuição vertical e fracionamento químico de fósforo em sedimentos do Rio Tiete (região de Pirapora do Bom Jesus, São Paulo)

“…A partir dos dados obtidos pode-se inferir que nas partes mais profundas do rio Estas observações também foram constatadas por Keulder (1982) em sedimentos da represa de Wuras (África do Sul) e em lagos americanos (Estados Unidos) por Clay & Wilhm (1979) e Frink (1969). Estes pesquisadores estabeleceram correlaçöes sign¡ficat¡vas entre a profundidade da coluna d'água do lago e o tamanho das partículas do sedimento.…”
