The SeaFET and SeapHOx systems are designed to sample at a fixed depth. If you want to run discreet samples at depth intervals, you will need to find a way to move the system to a specific depth before each sample interval and stop the descent / ascent for the entire...
An RTC (real time clock) is an electronic component which maintains an accurate time reference for the CTD. In the past, clock chips could be periodically calibrated to account for slow drift. As of the early 2000s, Sea-bird has been using components with improved...
The nominal control voltage for the relay is 12 VDC. However, between 5 - 30 VDC will work, applied to pin 4 relative to the ground pin 2 on the Deep SUNA V2. The voltage can be applied to the relay any time after external power is applied to the instrument for a...
Changing various settings, like the logging mode (moored or profile) or external sensor input channels enabled, will change the bit length of the scans stored in memory. For this reason, the previously stored samples in memory will no longer be interpretable in the...

SUNAs ordered with the 5mm path length coupler as a factory option will perform much better in low light transmission waters due to the shorter length the light needs to travel leading to less absorption. Equipping your SUNA with the factory bio-wiper option will also...
There are two ways the Navis float can start a mission without the user explicitly starting pressure activation or mission execute: (1) Not freezing the float: If the float is not frozen (I F command) before the communications dongle is removed, the float controller...
If all internal systems on the Navis float are functioning within normal parameters, the end of the floats functional life should be caused by the depletion of the main batteries. The only warning of eventual failure is that prior to full battery depletion, the float...
No. The Navis does not have charge monitoring capabilities. Typically information of that nature takes a coulomb counter chip, but the overhead with managing the data and powering such a chip is not a current Navis capability and is not expected to be added in the...
The ISFET has two reference electrodes: an internal reference and an external reference, that give separate reference potentials to the ISFET and show separate pH values (pH Internal and pH External). After the corrections for temperature and salinity are applied, the...
Celebrating and honoring our LGBTQIA+ communities It is in our DNA at Sea-Bird Scientific to embrace community and the beauty in diversity. As during previous Pride Months, we have changed our logo on social media to feature the colors of Pride throughout the month of...
We are pleased to partner with Scripps Institute of Oceanography to showcase a recent study done by Dr. Andrea Kealoha and her team at the University of Hawai’i at Mānoa in monitoring coastal water quality following the devastating wildfire in Lahaina in August of...
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. Using the HydroCAT-EP V2 to Study Coastal Water Quality Following the Lahaina Wildfire We were...
