The SBE 17plus V2 Searam provides power to and saves data from the SBE 9plus CTD (and integrated auxiliary sensors), without the need for conducting winch cable. The Searam includes Auto-Fire capability: when integrated with an SBE 32 Carousel Water Sampler, users can collect water samples at pre-programmed depths and record 9plus CTD data with one autonomous system. The Searam is typically installed in the CTD cage with the 9plus CTD; other mounting options are possible for Compact Carousels (SBE 32C) or custom applications.
The Searam’s auto-fire feature monitors pressure data transmitted by the 9plus in real-time, fires bottles on upcast at pre-defined pressures (depths), and records a firing confirmation for each bottle fired.
Each time the Searam is switched on by pushing in the magnetic switch, a file header containing date, time, and cast number is written to memory. The Searam’s memory can record full-rate CTD and 8-channel auxiliary sensor data (24 scans/sec) for approximately 6 hours. When desired, the data is uploaded to a computer. Sea-Bird software converts the raw CTD data and bottle fire confirmations and creates a CTD data file and a bottle data file.
OPTIONS • 6800 m aluminum housing, or 7000 or 10,500 m titanium housing. • XSG or wet-pluggable MCBH connectors. • AC-powered junction box (can provide external power to Searam, permitting setup and data upload without use of battery capacity).
