Seabird does not manufacture seacables for scientific winch systems and does not specify or endorse any specific cable material. The entire cable assembly must meet the following criteria: A single or multi-core armored cable up to 10,000 meters (32,800 feet) long; an...
Field Procedures & Deployment
How will cell fouling / contamination affect the conductivity / salinity data of a Sea-bird CTD?
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....
How should I store the ISFET pH probe on my Navis BGC float? What should I do before testing and deploying it?
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...
What is the recommended flow rate for a Sea-bird SBE21 Thermosalinograph flow thru system?
The recommended nominal flow rate is 1 liter/second (15.8 gallons/minute).
What maintenance can a user perform in the field on my ECO sensor’s wiper and optics face?
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; however, having the copper shutter...
Can I collect vertical profile data with my SeaFET V2, SeapHOx V2, or Deep SeapHOx V2 pH sensor?
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...
My Deep SUNA V2 has the optional APF relay feature. What voltage level is recommended to activate the relay? When should I apply power to the relay, and for how long?
The nominal control voltage for the relay is 12 VDC. However, between 5 - 30 VDC will work, applied to pin 4 relative to the ground pin 2 on the Deep SUNA V2. The voltage can be applied to the relay any time after external power is applied to the instrument for a...
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...
