Growth rate of suspended material

The capabilities of this technique are those of the method employed for the determination of an increase in biomass. In the particular example given here, the capabilities are the same as those given for the measurement of particle size spectra see Section IV.12). 

Note Two assumptions are made in the application of the technique as described here. The first is that the growth rate (k) remains constant and the second is that the quantity of detritus (D) remains constant. In addition, any initial living plant material which does not grow subsequently will be counted as detritus.  

Coulter Counter , Model R Several 1-liter clear glass-stoppered bottles in which to incubate sea water. 

Measure the size spectrum of suspended material in sea water as described in Section IV.12.IV.2. 

Incubate a 1-liter sample in a glass-stoppered bottle either at the depth from which the sample was taken or in a light incubator such as is employed in photosynthetic studies.
