My SUNA nitrate sensor is not transmitting or storing valid nitrate concentration data in high sediment, high turbidity, low light transmission environments, or freshwater inrush events. What can I do to mitigate this?

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...

Why did my Navis float unexpectedly start its mission during pre-deployment testing?

There are two ways the Navis float can start a mission without the user explicitly starting pressure activation or mission execute: (1) Not freezing the float: If the float is not frozen (I F command) before the communications dongle is removed, the float controller...

Can my Navis float to report available battery capacity or charge consumed?

No. The Navis does not have charge monitoring capabilities. Typically information of that nature takes a coulomb counter chip, but the overhead with managing the data and powering such a chip is not a current Navis capability and is not expected to be added in the...

How can I determine if an SBE9 or SBE9plus CTD is compatible with a specific SBE11 or SBE11plus deck box?

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"...

In an inductive telemetry system, what is the maximum recommended resistance of the mooring wire and seawater return path that would allow communications to function properly?

We do not specify a maximum line resistance. However, the Inductive Modem systems are very tolerant of the resistivity of seawater. It is typically only a consideration when the system is being deployed in freshwater lakes, etc. where the salinity level is a lot...

Why do we recommend against using Lithium battery packs with pumped 16p CTD’s?

Lithium battery packs are not suitable for use with 16plus units that have the 5T or 5M pumps installed as the drain on the battery is significantly higher. This effect causes deployments to be shorter and is not reflected in the SBE Deployment Endurance software,...

Can my 9p CTD be used in fresh water environments?

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....

My SUNA nitrate sensor is not transmitting or storing valid nitrate concentration data in high sediment, high turbidity, low light transmission environments, or freshwater inrush events. What can I do to mitigate this?

What tests can I do in the field or in my lab to test the functionality of my ECO-PAR? Can I calibrate or validate my readings by myself?

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...
