The answer to this question depends on your budget and your level of confidence that the entire system is functioning properly. When Sea-Bird receives CTDs that have integrated auxiliary sensors produced by other manufacturers, we test the functionality of the entire...
Sea-Bird does not repair or recalibrate other manufacturers’ instruments that have been integrated with Sea-Bird equipment. If an auxiliary sensor needs to be repaired or recalibrated, we recommend that you send it directly to the manufacturer. If you send it to...
Adding the sensor(s) is reasonably straightforward:Mount the sensor; a poor mounting scheme can result in poor data. Note: If the new sensor will be part of a pumped system, the existing plumbing must be modified; consult Sea-Bird for details.Attach the new...
Alkaline batteries can be shipped installed in the instrument. See Shipping Batteries for information on shipping instruments with Lithium or Nickel-Metal Hydride (NiMH) batteries.
On most of our instruments, replacement of the pressure sensor should be performed at Sea-Bird. We cannot extend warranty coverage if you replace the pressure sensor yourself.However, we recognize that you might decide to go ahead and do it yourself because of...
Yes, provided the SeaFETTM sensing elements remain ice-free, the instrument works across the broad temperature range of 0 to 50 deg C. The original SeaFETTM prototypes developed at MBARI and SCRIPPS were deployed extensively in the Antarctic for several...
For SBE 4 conductivity calibrations, Sea-Bird uses natural seawater that has been carefully collected, stored, UV irradiated, and filtered. Artificial seawater is not adequate if calibration errors are to be kept below 0.010 psu. Note: SBE 4 is the...
The difference between downcast and upcast is most likely related to package wake. When the CTD is mounted under a large water sampler, the variation can be on the order of 5 to 8 meters. This is due to the shadowing of the CTD sensors by the water sampler.
One of the reasons that this is not a simple question is that there are several factors to take into consideration regarding the error margin for practical salinity measurements. Salinity itself is a derived measurement from temperature, conductivity, and pressure, so...
The FIRe System measures changes in chlorophyll fluorescence that occur during a short (100 - 400 ?s) but intense (> 20,000 ?mol photons m-2 s-1) flash of light whereas the PAM approach measures the fluorescence induced by a weak modulated light source while using...
The Oceanography Society (TOS) and Sea-Bird Scientific are proud to partner in hosting a webinar focused on sharing insights and advice with current students or recent graduates on how they can transition from their education to a role in academia and/or industry....
Thank you to the Scripps team for hosting us!Earlier this month, experts from the Sea-Bird Scientific team had the pleasure of heading to Scripps Institute of Oceanography to present at an in-person Technical Forum to Scripps faculty and students.With a...
Celebrating Earth Day with Sea-Bird Scientific Sea-Bird Scientific is proud to play a part in protecting and better understanding our oceans, and ultimately our planet. We are so grateful to work collaborators, partners, and customers, who are doing instrumental...
