| Definition | An oceanographic sampler designed to be towed behind a vessel at a rate of 2-4 knots. The sampler includes 7 nets with mouth openings of 10cm internal and 160cms long. The nets are mounted in a removable stainless steel frame, which fits into the main stainless steel sampler frame, and can be changed to suit sampling requirements. The system can be fitted with live codend buckets or codend bags of similar mesh to the sampling nets. The system is pre-programmed using a computer which allocates depths where the sampler will activate.The operator can elect to sample down and up through the water column or only on the down leg or up leg. The main nose cone contains a Marine Scotland titanium flowmeter whose measurements are recorded on a data logger. The system also contains a motor that controls the opening and closing of nets. The system also normally carries 7 water sampling bottles, an optical plankton counter and an SBE911 CTD fitted with transmissometer and fluorometer. The sampler is rated to 1000 m and can carry up to 250kg of other instrumentation. | ||
