Underway SOMMA (AOML-2) Operations, Data Reduction and Quality Control:			
			
Operations:			
1. May 7:	Departure from Miami		
2. May 13:	The system hang up at 23:15		
3. May 18:	The system hang up at 9:55 while filling pipette.		
		The system hang up during salinity determination at 21:15.		
4. May 19:	Shut down the system at 23:30 for Lisbon import.		
5. May 20:	Arrival to Lisbon.		

Data Reduction and Quality Control:			
1. The quality of the TSG data seemed to be poor. Therefore a salinity correction was only applied			
    for the sampled which had a default value of 35 (samples collected 5/8 at 13:34-15:26).	
2. CRM correction:	
    CRM Batch #42	
    Average: 		1983.388833
    Stdev: 		2.868968833
    Certified value:	1985.1
    Number of CRMs:	6
    Correction:		1.711166667
3. LAT and  LONG were merged.	
4. Quality control:	
    The following plots were created and used to evaluate the data:	
    TCO2 vs. Julian Time	
    TCO2 vs. LAT	
    TCO2 vs. LONG	
    Chlorophyll  vs. Julian Time	
    Chlorophyll  vs. LAT	
    Chlorophyll  vs. LONG
    Chlorophyll vs. TCO2
    Temperature vs. TCO2
    Salinity vs. TCO2
    fCO2 (water) vs. TCO2
    fCO2 (air) vs. TCO2
