Floro


Density Array Fluorometer summary data



Mounted at a nominal depth of 8m on a cable at the MVCO Air-Sea Interaction Tower along with 3 microcats at 2 meters, 8 meters and 14 meters.  For a more acurate depth, see associated data ucat08_s.


Sensors on density array were Wetlabs FLSB or FLNTU (with backscatter for turbidity)  ... see after table below:


FLNTU


FLSB


Most of the data parameters include values for the mean and median value
as well as the standard deviation of the variable.  The table below shows
the field name suffix used to differentiate amoung the different values:





Field name Description



_mean The mean value of the variable over the averaging period



_m50 The median value of the variable over the averaging period



_std The standard deviation of the variable over the averaging
period



_length The number of valid data points collected over the averaging
period








Here is the list of field names:

Deployed 9/4/07 - 12/9/07 



FLNTUSB-693 (calibrated 3/29/07)


Sf = 0.0059, off = 49 & beta: Sf_b = 1.759e-5, off_b = 48 


maxcounts = 4121


NOTE:  baud rate issues at beginning of deployment






Deployed 12/9/07 - 


FLSB-417 (calibrated 6/1/2007)


Sf = .0079 and off = 87


maxcounts = 16330


NOTE:  deployed 12/9/07, but mininode failed (bad connector), so no data until 1/16/08


NOTE:  mininode failed again (bad Ethernet connector) 2/25/08; replaced by DAC_moxanode 3/13/08
