OOI community workshop begins, I explore the ocean from the back of the room

Quick update as I sit in the back of the room at the OOI community workshop.  We will be re-tasking the gliders based on input from the community here at the workshop.  So a quick check on the progress from last night.  The gliders have made good progress overnight and I believe we will be able to reach the way-points defined by the reachability envelop.  Of course there is variability in the envelops depending on the ocean forecast used and we should get valuable glider  information on which model envelop provided the best representation of the ocean experienced by the gliders.  Yesterday, the ensemble was spot on to the glider location.


Today I am going to be a biologist, once again showing my obsession with the Mid-Atlantic Bight winter bloom.  The bloom appears to be growing in intensity, and there appears to be increasing water column structure.  The phytoplankton appear to inceasingly found in the upper water column, earlier in the deployment the phytoplankton were distributed throughout the water column.  The intensity of the blooms appears to have increased as blooms have segregated int the surface waters.  One of the paradigms is that winter blooms are driven by light regulation.  Historical analysis suggests that the phytoplankton bloom in the winter when winds are low and the water column is somewhat stable allowing the cells to maintained in the upper water column where there is sufficient light to grow.  Looking at the temperature records from the gliders it appears that the water column shows some increased stability as indicated by the evolution of some moderate thermal structure.  The blooms appear to be associated with the changes thermal structure.  The salinity has not changed over the deployment period, with a nearshore slug of low salinity water.
