The SeaSave data visualization and processing software relies on a few factors in order to establish communications with your CTD and to process your data correctly. Some issues prevent good data from being displayed, while others will prevent communication entirely....
Software & Data Processing
Can my SBE 18 pH sensor be run in a freshwater bath as well as salt water?
Yes, like the HydroCAT EP's glass bulb pH sensor, the SBE 18 pH probe is capable of running in both fresh and salt water. If you have questions about your sensors accuracy or storage recommendations or suspect your sensor has lost accuracy, please contact Sea-Bird...
What is the difference in pressure calibration for a Deep SBE41 versus an SBE61?
The deep SBE41 and SBE61 use the same pressure sensor - a 7000dbar Kistler. And, they are calibrated with the same Paroscientific Digiquartz reference. However, the calibration process is different. A deep SBE41 receives a 2-point sensor only temperature compensation...
How can I change the USER and PWD (password) credential settings on my Navis float?
The menu to configure the factory parameters you are asking about is accessible through the i*? command. The ? argument for this command will give you a list of all of the arguments to change each individual menu. Let me know if you have any questions about the list...
Can I program my SUNA to start at a preferred time?
Unfortunately, users cannot currently program their SUNA to start at a preferred time. As soon as the SUNA is powered, the instrument will begin it’s programmed sampling mode on the hour. Users can use the offset feature to change the start time. For example, an...
How do I use Continuous Mode on my SUNA V2?
The continuous mode setting allows the user to program their SUNA to run continuously for an indefinite amount of time. When power is supplied to the SUNA, it will start data acquisition without an end time or maximum number of frames to measure. In general, we do not...
How do I use Fixed Time Mode on my SUNA?
The fixed time mode setting allows the user to program their SUNA to run continuously for a period of time or specified number of frames. When data acquisition has completed, the sensor will enter a low-power standby mode.
How do I use Periodic (Autonomous) Mode on my SUNA?
The periodic mode setting allows the user to select how often, and how long sample intervals are based on frame-based or time-based operation. For example, if a user would like to program their SUNA to sample every two hours, they would use a sample interval of two...
What is the effect of temperature drift on practical salinity for my CTD?
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 salinity reading...
Why does the specified range of the ECO BB sensors (expressed in m^-1) not match the maximum output calculated from my calibration sheet (expressed in m^-1 sr^-1)?
The back-scattering measurements are a portion of the total beam attenuation coefficient of the water being sampled. The beam attenuation is measured during the back-scattering calibration. Therefore, the range specification on the data sheet for the BB sensor (0 – 3...
