Model 1015-12 Position 1.2L Bottles and PM-12 Deck Command
Models 1015-12 and 1015-24 Rosette® multibottle arrays - accommodating 12 or 24 bottles - are two- component systems (deck command unit and a submersible bottle mounting array) for remotely actuating (in sequence) General Oceanics water sampling bottles.
Model 1015 series Rosettes are used with models 1010 Niskin , 1080 GO-FLO, or 1010X external spring bottles. The Rosette can be operated either independently, or in conjunction with CTD systems.
Bottles on the Rosette may be fitted with model M1000-3 or M1000-4 reversing thermometer assemblies (number and volume of bottles determine number of thermometer-reversing assemblies). All presently manufactured Rosettes have adaptor plates with a hole pattern to allow the bottles own tripping mechanisms to snap securely in place, and to permit quick attachment or release.
Only a single-conductor hydrographic cable is required, since the CTD is taken off line automatically during the 10-second Rosette sampling sequence.
Polarity of the Rosette can easily be changed by switches in the rack-mountable deck command box and electronic module in the underwater unit. Therefore, any CTD system now on the market can function with a G.O. Rosette system.
Generally, the CTD system is attached with clamps or interconnecting plate just beneath the Rosette and protected by the Rosette stand. However, a number of CTD's have been mounted directly on the Rosette in place of a bottle (attachment supplied by General Oceanics). The engineering department at General Oceanics, Inc. will assist the customer in designing the best mounting configuration.
