Journal article showing evidence that saccharides are key player in iron biogeochemistry as they form bioavailable organic form of iron mainly as colloidal iron.

The potential toxicity of elevated selenium (Se) concentrations in aquatic ecosystems has stimulated efforts to measure Se concentrations in benthos, nekton, and waterfowl in San Francisco Bay (SF Bay). In September 1998, ...

Dinoflagellate cysts are well-recognized biological constituents of ships' ballast tanks. They are present in ballast water, sediments and residual water in drained tanks, and in biofilms formed on interior tank surfaces. ...

A ratiometric luminescence intensity imaging approach is presented, which enables spatial O2 measurements in biofilm reactors with transparent planar O2 optodes. Optodes consist of an O2 sensitive luminescent dye immobilized ...

The elemental distribution of trace elements in banded Australian sedimentary opals from the Lightning Ridge region was investigated using secondary ion mass spectrometry (SIMS). Data were acquired using both spot analysis ...

A ground-water model was developed for Miami¿Dade County Florida, which lies within the Southeast Atlantic Coastal Zone, as a predictive tool that will be used to analyze different water-management scenarios, including ...

The combined effects of food concentration and population density on some life history characteristics of the small-bodied cladoceran Ceriodaphnia cf. dubia were studied by examining animals maintained at densities ...

Three environmental change scenarios (the best scenario, the most likely scenario and the worst scenario) were used by the APSIM (Agricultural Production System sIMulator) Wheat module to study the possible impacts of ...

This paper examines changes in isotopic abundances for 18O and deuterium in precipitation over the Amazon basin based on data in the Global Network on Isotopes in Precipitation (GNIP) database from the International Atomic ...
