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...
Example Data: Temperature and Conductivity are two of the most important values taken into consideration when our instrument calculates the practical salinity of seawater. When one sees a change in a measured value, such as temperature, that change will affect your...
Whether the tau correction is applied depends on where the system is being deployed.nnIf the system is to be used in shallow, coastal waters where large vertical gradients that change quickly are expected, the tau correction should be applied, as it accounts for the...

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...
There are two ways the N2 can start a mission without the user explicitly starting pressure activation or mission execute.nnNot Freezing the float:nIf the float is not frozen (I F command) and the dongle is removed, the N2 will eventually timeout. This is more of a...
Sea-Bird Scientific was proud to host an Ocean Science Mixer and Networking Event in Seattle, Washington, on June 1, 2023 for World Oceans Day. Following our virtual webinar on Forging Your Career in Academia and Industry in partnership with The Oceanography Society...
On Wednesday, July 12th, the team at Sea-Bird Scientific took time out of their day to go to one of our local beaches and pick up trash. Early July is an especially critical time of year to do beach clean-ups, given the proximity to the 4th of July in the United...
Hands Off and High-Quality Data: Using the HydroCAT-EP V2 to Get the Full Picture of a Dynamic Aquatic Ecosystem “King County, Washington’s mooring program is designed to collect continuous oceanographic and meteorological data every 15 minutes in Central Puget Sound....
