The net is hauled vertically from 40m and the methods used are designed to replicated the methods used by PML at the L4 plankton sampling station.

Hauled from 40m at a rate of 0.2m/sec. Assumes 95% effeciency. Final abundance is calculated as n/m3 but that comes from a count per sample then divided by an estimate of the sample volume, there is also a * 0.95 adjustment added. Formula used is depth of sample multiplied by 0.159 (diameter of net) multiplied by 0.95.
