an experiment from the Ice Island T-3. A sensor array of current meters
and thermistors (described later on) was suspended beneath the sea ice of
Colby Bay, T-3,...
Various methods of presenting and mathematically describing particle
size distribution are explained and evaluated. The hyperbolic
distribution is found to be the most practical but the more complex
characteristic vector analysis is the most sensitive to changes in
the shape of the particle size distributions.
Particle size distribution, nutrient concentrations,...
