Glider status on morning of May 30
The morning finds the glider fleet moving well. Overall all five gliders are surveying their respective zones effectively. Discussion will ramp up after the Memorial day weekend on not only piloting the gliders in the water but also plans of where to deploy the new gliders in the coming week. We expect that Scripps, Rutgers, and U Delaware gliders to join the effort next week, and deciding where to deploy will be a big focus. Depending on repairs perhaps Waldo and BASS will return, depending on the ongoing efforts to reconcile the issues encountered last week.
The NAVO gliders (blue dot indicates their area of operations in the map above) continue their survey over Mississippi canyon. Not many changes from the analysis from yesterday, with enhanced CDOM at depth. The values slightly higher then the Florida gliders, however they are collecting data deeper, so it is difficult to assess whether these values are anomalous.
Looking at Seaglider we see good progress.No more deep water CDOM anomalies and confirmation will be interesting. The enhanced CDOM at depth was also associated with enhanced chlorophyll fluorescence. Regardless the Seaglider shows the greatest depth-depend variability of the other four glider systems, which given its proximity to the spill will be a big area of focus in the coming week. The ship data will be invaluable.
SAM is flying well. The general features show a stratified system with a chlorophyll maximum at the thermocline and CDOM values enhanced in the bottom waters.
RU21 is definetely entrained in the eddy, encountering strong southerly flows. The glider has ~18 days of battery left using all instruments. Also given that data within the eddy will nt be useful for this mission, the glider has been given a waypoint east. The glider should fight its way out the eddy, and we will conduct shelf line. The data snapshots this morning are not much different then as we saw yesterday. Particle load, shows a maximum associated with the pycnocline but values are lower than was encountered on the shelf. CDOM values lower in bottom waters below the pycnocline. We track the progress of ru21 over the next day to see the progress getting out of the eddy edge.
