                                                     CTD   Fluorescence Notes

1) OC415-1  two fluorometers.
----------------------------------------

There were two  CTD fluorometers during the OC415-1 cruise time.
Fluorometer #1, Voltage 1  - did not work properly;
Starting from station #24 new Fluorometer #2, Voltage 3 has been installed on CTD replacing the Seapoint turbidity meter. 

So, correct Fluorescens data  in CTD data files is:
 # name 7 = upoly1: userpoly 1    Extrnl Volt  3  userpoly 1, flrtd-297, 6/27/05
and is available only starting from the  station #24. Please see CTD data heders:
 
Stations ## 1-23:
# name 6 = upoly0: userpoly 0  Extrnl Volt  1  userpoly 0, afl013, 12/09/2002
# name 7 = seaTurbMtr0: seapoint turbidity meter [FTU]  Extrnl Volt  3  seapoint turbidity meter, 1660

 Stations ## 24-81:
# name 6 = upoly0: userpoly 0   Extrnl Volt  1  userpoly 0, afl013, 12/09/2002
# name 7 = upoly1: userpoly 1    Extrnl Volt  3  userpoly 1, flrtd-297, 6/27/05

Note that 'bad' Fluorometer #1 has not been removed from CTD as well as the related data from CTD data files. 


2) CTD Fluorescence data correction versus Bottles Chlorophyll plus Phaeopigments.
-------------------------------------------------------------------------------------------------------------

OC404-1 and OC404-4 Fluorescence has been corrected opposite Bottles Chlorophyll plus Phaeopigments.
 OC415-1 and OC415-3 Fluorescence has not been corrected in processed data files and can be corrected by computing using Bottles Chlorophyll plus Phaeopigments data.

Note that  OC404-1 and OC404-4 Fluorescence profiles are kind of noisy and there are some surface outliers (~3-10 times of Bottle measurement, e.g. OC404-1 stations ## 2, 5, 12, 22, 23)
