The ECO-PAR, due to the nature of PAR sensors, cannot be accurately calibrated outside of the Sea-Bird facility. However, there are some functionality tests that can aid in pre-deployment. A bright flashlight can validate whether the instrument sees light at all. On a...
There are two optional modifications that can be done to your 9p at our facility (during service or as part of your original order) that will allow the 9p CTD to operate in freshwater deployments. The 9p's pump will not operate in freshwater without these options....
The spike seen in the pump out phase is due to the commencement of flow and reagents/material that is outside the optical path initially but is swept through the optical path during flush out. The spike is accepted as normal behavior of the system and does not affect...
Cells that have been contaminated with foreign material generally read low of the actual conductivity. Your zero (in air) conductivity reading is generally unaffected. The conductivity error due to fouling will generally be proportional to the conductivity value....
Oftentimes one will see data in their cast that looks erroneous or out of spec, but reviewing the timeline of each cast and the events which transpired can explain these jumps. If you are starting your cast while your CTD is on deck then the time during which the unit...
The primary maintenance procedures that are outlined in the manual are for the bio-wiper (shutter) installation, the internal battery replacement and the bulkhead connector inspection. The shutter replacement is not always necessary, but, having the copper shutter and...
The temperature and salinity correction for the SUNA can be traced to the experiment outlined in Sakamoto et al. 2009, which is the T/S correction our UCI-based SUNA software uses in post-processing only. Absorption of UV light in seawater is dominated by dissolved...
When your max lamp counts drop below 30,000 during the self test and cannot recover with cleaning, you can send the lamp in for inspection. If your lamp time remaining is less than 25% then it is best to send the SUNA in for a lamp replacement. We will automatically...
There are several considerations when determining whether the deck box and CTD underwater unit will be compatible. (1) In most cases (with the exception being (2), below), instruments with the "-plus" designation are compatible with each other, but the "-plus"...
The measurement range and accuracy of the SBE43 are not defined in discrete units (mL/L, mg/L, µMol/L, etc.) Rather, the range and accuracy specification are expressed as a ratio of the calculated oxygen saturation point. This saturation value depends on the...
We hope to see you at #Oi24 We are excited to return to Oceanology International 2024 again in London, UK from March 12-14. Overview Oceanology International brings together 500+ exhibitors in the only event that links the three key players in the industry:...
We hope to see you at #OSM24 We are excited to return to Ocean Sciences Meeting 2024 in New Orleans, Louisiana from February 18-23 at booth number #527. Overview The Ocean Sciences Meeting 2024 is co-sponsored by the American Geophysical Union, the Association for the...
Come See Us at AGU in San Francisco! Sea-Bird Scientific is excited to exhibit at the upcoming AGU Fall Meeting taking place in San Francisco, California, from December 11 – 15, 2023. Please come see members of our team at booth #604 to get answers to your...
