In addition to net tows, plankton is collected while the research vessel is moving using a Continuous Underway Fish Egg Sampler, or CUFES. Water is pumped aboard the vessel from 3 m depth at 640 liters/min. The water is sent through a concentrator where it passes through a net, and the plankton is diverted to a collector. While CUFES is running, a data logger is recording the date, time, and position for each sample as well as other environmental data from the ship's sensors (e.g. wind speed, direction, SST).
