A meter net is a plankton net with a one meter diameter opening and a mesh size of .333 mm, towed horizontally, obliquely or vertically, also known as a Ring Net.
1M (mouth opening) 5M length 200 µm mesh cone plankton net equipped with a filtering (202 µm mesh) cod-end. The mouth of the net was mounted in a swivel towing frame that allowed the opening of the net to track the water current. A mechanical flow meter (General Oceanics Part# 2030RC) was mounted in the center of the net.
