The Thetis system uses on board batteries (BlueFin Robotics, 1.5kW) for power.
Field Procedures & Deployment
How many/what kind of spares should I have on ship for my instrument?
Very few Sea-Bird instruments completely fail due to component malfunction or manufacturing defects. However, we see a reasonably large number that require repairs of some sort. Most of these are simply due to the user breaking the equipment through rough handling,...
What location information does the Thetis provide, and are there emergency position locator features for the Thetis?
All Thetis models include an integrated GPS system. GPS acquisition times are typically less than 2 minutes. The GPS is only activated if a break-away condition has been detected.There is an option to integrate an autonomous (self-contained and powered) Iridium...
Does it matter if I deploy my moored instrument, which includes a conductivity sensor, in a horizontal or vertical position?
Yes, vertical is usually preferable. In the presence of consistent currents and suspended sediment, we have seen instances where a horizontal conductivity cell is scoured by the abrasive effect of the flow. When scouring is particularly intense, the electrodes can be...
What is the maximum cable length for real-time RS-232 data?
Cable length is one of the most misunderstood items in the RS-232 world. The RS-232 standard was originally developed decades ago for a 19200 baud rate, and defines the maximum cable length as 50 feet, or the cable length equal to a capacitance of 2500 pF. The...
How can I identify and fix bubble spike failures in my Hydrocycle data?
First off, let’s see what a relatively good Raw Data Plot looks like. The different phases are the pre-flush phase (dark blue), the ambient baseline reading period (red), the sample reagent pump phase (green), the sample read/reaction phase (purple), and finally the...
