Geomicrobiological Features of Ferruginous Sediments from Lake Towuti, Indonesia
Lake Towuti is a tectonic basin, surrounded by ultramafic rocks. Lateritic soils form through weathering and deliver abundant iron (oxy)hydroxides but very little sulfate to the lake and its sediment. To characterize the sediment biogeochemistry, we collected cores at three sites with increasing water depth and decreasing bottom water oxygen concentrations. Microbial cell densities were highest...
متن کاملCharacterizing clay mineralogy in Lake Towuti, Indonesia, with reflectance spectroscopy
We tested the use of visible to near-infrared (VNIR) reflectance spectroscopy to characterize the relative abundances of clay minerals in sediments from Lake Towuti, a large tectonic lake in Sulawesi, Indonesia. We measured VNIR spectra of lake and river sediments from Lake Towuti and its catchment to identify clay minerals, fit major VNIR absorption features with a modified Gaussian model to e...
متن کاملPreservation and Significance of Extracellular DNA in Ferruginous Sediments from Lake Towuti, Indonesia
Extracellular DNA is ubiquitous in soil and sediment and constitutes a dominant fraction of environmental DNA in aquatic systems. In theory, extracellular DNA is composed of genomic elements persisting at different degrees of preservation produced by processes occurring on land, in the water column and sediment. Extracellular DNA can be taken up as a nutrient source, excreted or degraded by mic...
متن کاملMalaria in North Sulawesi, Indonesia
The incidence and impact of malaria in North Sulawesi have declined both in the short term during the 1990s, and over a much longer timespan (though perhaps less continuously) since the end of the colonial period. The improvement already seems to have been well underway before deliberate vector control activities became extensive in the second half of the 1970s, and environmental changes affect...
متن کاملPaleolake Deposits on Mars: Perspectives on Source-to-sink Mineralogy from Lake Towuti, Indonesia
Introduction: Ancient paleolake basins are amongst the best evidence for surface fluvial activity early in martian history [e.g., 1-3]. Many of these paleolakes contain sedimentary deposits formed when there was standing water within the basin [e.g., 1,2,4]. Study of lacustrine sedimentary deposits on Earth can provide fundamental constraints on martian paleolake deposits, which are largely res...
