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....
The pH sensor will be shipped dry but was pre-conditioned in seawater (generally from Pacific Ocean waters near Hawaii). While conditioning and evaluating the pH sensor, only expose it filtered, sterilized natural seawater. Do not use seawater CRMs (Certified...
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...
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...
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...
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...
Artificial seawater is problematic because the salts in artificial seawater do not completely dissolve leaving you with a solution that does not completely match the ionic concentration of seawater. This is true for synthetic blends (made for aquariums) or ones made...
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...

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...
Scripps Technical Forum Time: Thursday, April 06, 2023 | 12:00 PM to 1:00 PM Location: Hydraulics Lab Mezzanine Sea-Bird Scientific is grateful for the opportunity to present at a Technical Forum to the Scripps Institute of Oceanography community. In this session,...
