Now from the North!
A second toast is in order for the IOOS team to the North. U Mass and Rutgers has launched a glider in the northern grid, and it is making great progress as it is heading south. The glider is carrying both optics and a CTD. A great deal of spatial complexity has been revealed. The glider last night was shipped into shipping lane beavior mode. This means it is will be not be surfacing very often, 12 hours, and when it does it gets a position fix, and heads back on its way. The glider also stays deep so as to pass under the ship traffic.
The salinity data shows a nearshore buoyant plume. Associated with the near-shore low saline water is enhanced concentrations of particles. The particles do not appear to be phytoplankton as the fluorescence showed no significant enhancement in these waters. This suggests that the particulate material is sand, silt, etc. The chlorophyll exhibits a sub surface bloom offshore the low salinity water. The phytoplankton concentrations are very high and given their depth would not be visible in satellite imagery. The phytoplankton concentrations offshore are also seen in enhanced optical backscatter. Hopefully clouds will blow out by the midday satellite passes so we can see if the bloom is visible by satellite.
