NEGOM Cruise N6:  Sample Log Notes
17-28 August 1999
CM # = chlorophyll maximum at depth of Niskin bottle #
SBS # = surface bucket salinity flask number

The two lists below contain comments made by the CTD operator and the data sample cop 
at the time of the casts.  These notes were made on the CTD Operator's Log and the Data

Station	Description
A	N6CORE00.  SBS #256.  12 bottles fired (in 33 m water depth); analyses only 
	for bottles 10 (bottom), 11 (middle), and 12 (surface).
0	N6TEST00.  All bottle tripped at same depth (720 m; sq of 27.45).  One bottle 
	fired at 714 m accidentally?  From bottle 8 onward valves were opened ahead 
	of taking oxygen samples.

33	CM 8, 7, and 6.
34	CM 5. SBS #306.
35	CM 4.  SBS #188.  Three bottles tripped at bottom (1, 2, 3) and three at surface 
	(7, 8, 9); Multiple POC samples taken to test variability.  Btl 6 was taken at the 
	beginning of salinity change (rapid increase).
36	CM 2.  SBS #178.
37	SBS #177.
38	SBS #183.  No real Chl max; all 4 bottles showed same line/curve/parameters.
39	SBS #179.  For 02, btl 4 had already been opened before O2 was taken.
40	SBS #263.

	Btl 8 leaks when air valve closed and spigot in (very much like a faucet)!
45	CM 8.  Btl 9 also had chl peak.  Had two bottles open at surface (one expected); 
	btl 11 did not fire-it was not properly set.  Bottle 12 closed on its own twice 
	before starting cast.
46	CM 10.  Salinity max at btl 6.  Btl 12 went down with air valve open.
47	CM 10.

52	CM 11.
53	CM 10.  Btl 10 went down with air valve open.  Btl 11 was also tripped very 
	close to chl max in case #10 is discarded.  There was a small film of oil on the 
	water at this station.
54	CM 8.
55	CM 8.  Btl didn't show going off (being fired) at CTD station, so we eliminated 
	that depth (79.2 m) and shifted all bottles.  Only fired 11 bottles here.

81	CM 7.  SBS #273.  Bottles tripped were Niskins 6-10, not 1-5.
82	CM 11.  SBS #184.  Oxygen flasks 737 and 004 broke.
83	CM 11.
84	CM 9.  Computer showed first 5 bottle fired at 284 m depth!  So readjusted 
	firing numbers; only 12 bottles fired (blt 1 shows as trip 6, btl 2 as 7,...,btl12 as 
	trip 17).  Btl 7 leaked.
85	CM 10.  Btl 9 leaking from bottom of bottle; changed bottom o-ring.
86	CM 11.  Muhlenberg College:  salinity sample flask 327 to compare with 190 
	(Niskin 10); flask 328 to compare with 66 (Niskin 5).
