While a CTD leak can result in a dangerous situation, it is not common. Pressure housings may flood under pressure due to dirty or damaged o-rings, or other failed seals, causing highly compressed air to be trapped inside. For example, a housing that floods at 5000...
Our current depth operating specification for the Thetis Profiler is in water columns ranging from 5 to 100m in depth. The Thetis Profiler has been most rigorously testing in 50 m offshore of Newport, OR, though other systems have been deployed in several other...
Sea-Bird’s CTDs are not directly affected by adjacent objects, unlike some CTDs that shift their calibration due to proximity effects. However, the CTD can only measure the water it sees. There are 2 concerns to keep in mind when mounting the CTD:If the CTD is...
The Thetis system uses on board batteries (BlueFin Robotics, 1.5kW) for power.
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,...
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...
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...
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...
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...
We were excited to partner with the Marine Technology Society (MTS https://www.mtsociety.org/) to bring you a webinar to walk through our new software. We’re excited to release Fathom – the latest in software innovation at Sea-Bird Scientific (SBS). Heather Eberhart,...
Welcome to the Sea-Bird Swell – our monthly newsletter that gives you the latest on what’s happening at Sea-Bird Scientific and the broader oceanographic community. Introducing Our New Software: Fathom Earlier this month, we released our new SBS Fathom software! Our...
Our Moored pH Ocean Monitoring Systems Ocean pH plays a critical role in the health of the global ocean due to the short timescales relevant to biological activity. With recent studies highlighting the impacts of acidification on the carbon cycle as well as on coral,...
