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.

Formula used is depth of sample multiplied by 0.159 (diameter of net) multiplied by 0.95. This data has been reviewed against the DASSH Quality Assessment Criteria (http://doi.org/10.17031/64ccec5c7ba72) and been categorised as high quality.
