Abstract
Two high-speed plankton samplers (Gulf VII/PRO-NET and MAFF/Guildline) currently in use to sample pelagic eggs and larvae in waters around the UK are described. Both samplers are modifications of Gulf III type samplers and are capable of being towed at speeds of up to 7 knots (3.6 m s−1). The performance of the samplers (flow rates, degree of clogging of the nets and sample depth profiles) can be monitored during deployment. The real-time monitoring packages also provide vertical profiles of temperature, salinity and chlorophyll a fluorescence. Both samplers can be constructed in different sizes to suit the vessel from which the sampler is deployed and the expected concentration of plankton in the sampling area.Keywords
