The redox and iron-sulfide geochemistry of Salt Pond and the thermodynamic constraints on native magnetotactic bacteria
… by steep redox gradients at the interface. This chemocline is a habitat for magnetotactic bacteria (MB), and the spatial and temporal distribution of MB in the system along with geochemical (Fe2+, H2S, pH, O2 (aq), etc.) profiles have been analyzed from 2002 - 2005. It has been previously …

Characterizing ancient chemoclines through the use of pigment biomarkers and sedimentary stable isotope signatures
… focuses on identifying and qualifying chemocline dynamics, namely depth and stability, in stratified aquatic systems through the use of sedimentary pigments and the stable carbon and nitrogen isotopes of organic matter. The central aim of the research comprising this volume is to …

In situ Metabolism and Biogeography of Phototrophic Consortia
… consortium "P. roseum" was investigated in the chemocline of a temperate holomictic lake (Lake Dagow, Brandenburg, Germany). Fluorescent in situ hybridization revealed that the brown-colored epibionts of "P. roseum" constituted up to 37 % of total bacterial cell numbers and up to 88 % of all …

The hydrological and limnological characterization of two Canadian water catchments sensitive to anthropogenic influences: Crawford Lake, Ontario and Old Crow Flats, Yukon
… maintaining density stratification across the chemocline. Chemical and isotopic analysis identified a dense, highly conductive groundwater-fed monimolimnion permanently isolated from a less dense, more dilute mixolimnion. High concentrations of dissolved oxygen were measured in the …

Facies, stratigraphy, and mineralogy of the carbonate marker and D marker units, lower Green River Formation, Uinta Basin, Utah
… to be a stratified lake with a well-developed chemocline. Beneath the chemocline waters were dense, highly saline, reducing, and anoxic to dysoxic. As a result, precipitation of analcime cement, ferroan dolomite, and the severe alteration or dissolution of clay species is common in the …

Algal and protozoan response to Holocene climate change and anthropogenic impact: a case study from Sluice Pond, MA
… tricuspis in the deep basin. Above the chemocline however, a diverse difflugiid thecamoebian assemblage is present.

Chlorophyll diagenesis in the water column and sediments of the Black Sea
… The chlorophyll which can be detected below the chemocline of the Black Sea in the form of chlorophyll degradation products will survive to be deposited in surface sediments. Once in sediments, chlorophyll degradation products are found in four different reservoirs: phorbin steryl esters, free …
