Weekly vertical net tows are taken from 5 m to surface in the lower West passage of Narragansett Bay, RI (lat. 41 34.2N, long. 71 23.4W). Gelatinous species are collected by two vertical tows taken with a ½ m diameter 1 mm mesh net with a flowmeter. They are combined into a single sample. Sample volume is 1.1 m3. This sample is returned to the laboratory and counted alive immediately to ensure that ctenophores, which do not withstand preservation, can be accurately enumerated. On occasion when there are soo many jellyfish that the net would clog a single vertical tow is taken.
