第34届国际湖沼学大会专题6：浮游生物动态对内陆水体甲烷通量和排放的影响（Effects of plankton dynamics on methane fluxes and emissions from inland waters）
第34届 湖沼学大会 浮游生物动态 内陆水体甲烷通量 排放影响
2018/1/20
Natural and man-made inland waters represent globally significant sites of methane production and emit annually about 100 Tg of this potent GHG to the atmosphere. On the other hand, a large fraction o...
Morphological variations of a manganese-oxidizing microorganism Metallogenium observed in the developmental process of cultures collected from Lake Biwa waters
Bacteria Fungus Manganese
2009/4/1
Blackish brown particles of manganese oxide usually derived from the microorganism Metallogenium were observed for the first time in November, 2002 at the center of the north basin of Lake Biwa off Im...
Distribution and speciation of Fe(II) in the waters of Lake Biwa and inflowing rivers
oxic environment inflowing rivers
2009/4/1
The extraction method of Fe(II)-ferrozine complex was modified to achieve detection of nanomolar concentrations of Fe(II) in freshwaters. This method was applied to investigate the distribution of tra...
Metal speciation in natural river waters: measurement by diffusive gradients in thin-films and estimation by chemical equilibrium model
Speciation DGT
2009/4/1
Metal bioavailability of and toxicity to aquatic organisms depend on their speciation. The chemical speciation of Ni, Cu, and Zn in two Japanese rivers was measured by diffusive gradients in thin-film...
Chemical study of river waters in U.S.military central training area of Okinawa Island
river water chemical composition
2009/4/1
Many U.S.military bases are located in the central and northern parts of Okinawa Island. A study on the river waters in such military training areas has been difficult to conduct until now. However th...
Seaborne measurements of near infrared water-leaving reflectance: The similarity spectrum for turbid waters
water-leaving reflectance Seaborne measurements
2014/5/4
Theory and seaborne measurements are presented for the near infrared (NIR: 700-900 nm) water-leaving reflectance in turbid waters. According to theory, the shape of the NIR spectrum is determined larg...
Bloom dynamics in early opening waters of the Arctic Ocean
Bloom dynamics early opening waters
2014/5/4
We measured the isotopic composition and accumulation of particulate organic matter (POM) and the uptake of carbon (C) and nitrogen (N) in an early bloom of the most productive recurring polynya of th...
Photodegradation of strong copper-complexing ligands in organic-rich estuarine waters
copper-complexing organic-rich
2014/5/4
ABSTRACT: Exposure to solar radiation substantially decreased the strong copper-complexing capacity of samples collected from the organic-rich Cape Fear estuary, North Carolina. Samples exposed to nat...
