A New Method For The Quantitative Determination Of Plankton Hauls, Henry B. Ward
A New Method For The Quantitative Determination Of Plankton Hauls, Henry B. Ward
Studies from the University of Nebraska Zoological Laboratory
Only two methods of estimating the quantity of plankton obtained in a haul of the vertical net are known to me. These two may be called the volumetric and the gravimetric. Both have been used by observers in various parts of the world, but so far as I know have never been comparatively tested in order to ascertain the relative value of results obtained by the two. The experience of the past year has shown some disadvantages in the first method, while the second has certain evident objections which rendered its employment in this case out of the question. In …
