| Definition | A British Antarctic Survey-built version of the Multiple Opening and Closing Net with an Environmental Sensing System (MOCNESS) originally designed by Wiebe et al. (1976) for capturing zooplankton. This version consists of nine nets, which can be towed to a maximum depth of 1000 m. A live data stream allows an operator on the ship to close a net, thus triggering the opening of the next one. The first net is open when the system goes in the water; when the maximum depth is reached, the operator triggers it to close, thus automatically prompting the next one to open. This mode of operation is repeated until all nets have collected samples. This system allows for accurate control over timing and location of samples, which are collected sequentially through the nine nets. The frame also carries a current meter and a CTD system. | |
