| Research Abstract |
Plankton nets have been used for as a method for collecting the plankton. Especially, the NORPAC-NET is widely used in order to keep the compatibility of the data and there are many long-term data based on the NORPAC samples. NORPAC-NET sampling is easy to operate, the wire angles often exceed 40 degrees when sea condition is rough. These would suggest that these samples were estimated over or less than the normal condition. Then, this study investigates the collection characteristic of the NORPAC net and the property of the long-term data set. Furthermore, the present study examines other plankton net, MTD-Net, Bongo-Net and the retention on the survey-net mesh.
