FloatViz 4.0 Quality Controlled Data- Apex/ISUS Data Visualization
An ISUS nitrate sensor in a Webb Research Apex profiling float
Map of float tracks
Autoscale X & Y axis :
Enter Ranges if Autoscale is Off (Min & max ranges default to 0 and 200 if Autoscale off and box is empty. Depth ranges are entered as negative values on Y axis and as positive values on X axis.)
* These floats have biooptical sensors for chlorophyll and backscatter in addition to nitrate, oxygen and a CTD.
** These were short-term test deployments and the floats were then recovered.
+ These floats have exhausted their batteries and are not operating.
o Oxygen concentration on these floats have have been quality controlled by adjusting raw data to fit Winkler titrations (more coming on process).
$ These floats were deployed near Hawaii between 2002 and 2008 and have all stopped operating. They have only O2 sensors.
$$ These floats either were not deployed with a nitrate sensor or the nitrate sensor has stopped and they have oxygen sensors only.
% These floats are equipped with Durafet pH sensors modified at MBARI to operate at high pressure. pH reported on the Total Proton Scale at in situ T/P and at 25C/1 atm.
