Yes, the SeaFET™ pH sensor comes with a flow through cell with fittings that can be plumbed with a pump for flow-through operations. For in situ deployments, we recommend the SBE 5P submersible pump.
GeneralLarge numbers of Sea-Bird conductivity instruments have been used in Arctic and Antarctic programs.Special accommodation to keep temperature, conductivity, oxygen, and optical sensors at or above 0 C is advised. Often, the CTD is brought inside protective doors...
We recommend keeping the connectors on your meter lubricated using a good quality silicone spray lubricant, such as 3M Silicone Spray or Loctite 8021 spray. These can be purchased at your local hardware store. Avoid silicone grease. It is messy and attracts...
The most complete backup system would be another SBE 9plus, to allow for very rapid system swaps. This is important if your stations are close together and there is limited time between CTD casts. However, it is the most expensive option.The next step down would...
The base sensing suite includes a FastCat CTD, a combined fluorescence and turbidity sensor, and a PAR sensor. The current supported list of instruments for Thetis include: CTD: SeaBird FastCat CTD (SBE49) Dissolved oxygen: SeaBird SBE43 or SBE63 Chlorophyll: ...
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...
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...
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,...
The Thetis system uses on board batteries (BlueFin Robotics, 1.5kW) for power.
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...

2022 has been quite the year in ocean science, and here at Sea-Bird Scientific headquarters. The end of the year gives us all an opportunity to reflect on our wins, things we are grateful for, and propels us to take some time to glimpse at what is to come in 2023. We...
On Friday, December 16, we were grateful to host over 30 NOAA Marine Technicians from across the US at our headquarters in Bellevue, Washington, to provide on-site training on various Sea-Bird Scientific technologies and instruments. (Chris Cheshier, Technical Support...
