N70 plankton net
My colleague the zooplankton ecologist Peter Ward wanted to compare the old data from the Discovery cruises with modern data. To make this comparison possible he wanted to use an identical net, the scientist used nearly 80 years ago. So he asked me to rebuild such a plankton net. We decided on what they called a N70 plankton net and based on the old drawings and descriptions of the Discovery reports I brought the N70 back into live. The net was then successfully used on one of our research cruises to collect zooplankton the same way, scientist did a on the Discovery cruises.
