The OECD International Programme on Eutrophication has been designed for cross sectional comparison of lakes to provide management with simple tools to evaluate nutrient reduction, particularly phosphorus, necessary to ...

A suitable sampler for taking undisturbed sediment samples was developed. Techniques were worked out for measuring (a) oxygen uptake by intact sediment cores, (b) dehydrogenase activity of sediment bacteria, and (c) their ...

Sediment cores were obtained from 15 lake stations representing the three major basins and the Inshore Zone of Lake Ontario. Cores were sectioned for characterization of the surface sediments according to inorganic P ...

This paper describes MACSYMA’s symbolic ordinary differential equation solver ODE2. Although available in MACSYMA for approximately three years now, a paper describing how to use it had never previously been written. Also, ...
