Oftentimes one will see data in their cast that looks erroneous or out of spec, but reviewing the timeline of each cast and the events which transpired can explain these jumps. If you are starting your cast while your CTD is on deck then the time during which the unit...
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...
There are several considerations when determining whether the deck box and CTD underwater unit will be compatible.nn(1) In most cases (with the exception being (2), below), instruments with the "-plus" designation are compatible with each other, but the "-plus"...
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...
The only warning of eventual failure is that prior to full battery depletion, the float will typically see a voltage drop with 5-15% of the float life remaining.
This issue can have a few different causes. The most common cause is noise from your Data I/O connector on your CTD. This noise can be caused by a shorted serial deployment cable or water intrusion under the dummy plug on the I/O connector. To solve this issue, we...
Cells that have been contaminated with foreign material generally read low of the actual conductivity. Your zero (in air) conductivity reading is generally unaffected.nnThe conductivity error due to fouling will generally be proportional to the conductivity value....
"The requirements of a GPS to enable data collection with Sea-Bird Scientific's SatView software are: 1. NMEA 0183 Output 2. Serial connection The SAS GPS option includes a prewired Garmin model GPS 17xHVS. This model is designed for marine use,...
