FloatViz 4.0 - Apex/ISUS Data Visualization

An ISUS nitrate sensor in a Webb Research Apex profiling float

What's new? Floats 6091, 7557, 7567, 7613, 7614, 9091 (w/pH), 9092 (w/pH), 9031 (w/pH), 9018 (pH, no NO3 or optics), 9095 (w/pH), and 9101(pH, no NO3 or optics) were deployed in the Southern Ocean from R/V Revelle on the US Repeat Hydrography P16S cruise . This project is supported by the US NSF Polar Programs with some floats contributed by NOAA through the US Argo Program.
Float 0276 was deployed in the North Atlantic. 0276 is a Sea-Bird Navis float with nitrate, oxygen and biooptical sensors. Temperature, salinity, oxygen (SBE 63) and optical data (MCOM - chlorophyll fluorescence, backscatter and CDOM) are at 2 meter vertical resolution. Float 8514 was redeployed at the Hawaii Ocean Time series (HOT) station on Jan. 18, 2014. This float had been recovered to repair faults in the pH and O2 sensor electronics.

* 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.
