Data Collection Form
CM# = number of bottle in chlorophyll maximum (CM0=none noted).

Station	Description
0	CM0.  Niskin 1, oxygen flask 75, sample had large bubble, toss.
1	CM11.  24.6 sigma-theta surface not sampled.  Bottle 10 did not fire because locking mechanism not pushed in.  Bottle 4 air valve was loose.
2	CM10.  
3	CM10.  
4	CM9.  Bottles 7 and 9 had no confirmation mark.  Niskin 12 did not close.  Bottle depths of Bottles 7-12 uncertain.
5	CM8.  
6	CM3.  Secondary chl max at bottle 10 (15m) almost as large as at bottle 3 (77m).
7	CM2.  
8	CM12.  Niskin 12 fired first.
9	CM1.  Nepheloid layer at Niskin 1.  DIC sample taken from Niskin 4.
10	CM0.  
11	CM0.  No discernible chl max.
12	CM0.  No discernible chl max; highest fluorescence. value at bottom.  Larger diameter tubing used for oxygen sample on bottle 4 (due to DOC sample drawn); bubbles noticed in tubing but not in flask.
13	CM1.  no clear-cut chl max; highest values at bottom.
14	CM2.  
15	CM2.  
16	CM0.  No chl max information available (fluorescence off scale).  Bottle 7 spigot leaking; operator error.
17	CM8.  Bottom nepheloid layer at bottle 2.
18	CM9.  Chl max at 75m.  Salinity max ~75-125 m.
19	CM9.  
20	CM10.  
21	CM10.  
22	CM10.  
23	CM10.  
24	CM9.  
25	CM10.  Chl max at 72m; salinity max ~110m.
26	CM9.  Nepheloid layer 165-180m; chl max at 70 m; salinity max at ~80m.
27	CM8.  Chl max at 82m; salinity ma ~91m.
28	CM0.  Water column stable down to 79m; no structure below (sic) 79 m.  No changes in salinity, temperature, transmissometry, density (only 2 density levels available).  Chl max not available; fluorescence scale not on screen; tripping only 6 bottles authorized by John Walpert, "Data Cop".
29	CM2.  Bottom nepheloid layer at 35m - bottom.
30	CM2.  Niskin 7 is surface.
31	CM1.  No real chl max seen, although fluorescence value slightly higher at bottom than at surface.
32	CM0.  No chl max could be determined.  Double trip at surface; not sure 1st closed (#3) so fired a 2nd (#4) to be safe.  Unplanned pigment samples were taken.
33	CM0.  
34	CM4.  Chl max at 7m; another chl peak at 17.5m.
35	CM1.  
36	CM8.  Chl max at 73m.  Bottom nepheloid layer at 120m. Intermediate nepheloid layer at 100m & 80 m.  Bottle 3 leaking from bottom, drew oxygen as soon as we noticed.
37	CM9 & 11.  Xmiss upcast no matching downcast.  No real chl max; not a single peak (2 almost the same)-smaller "peak" at 10m as well.  Bottle 11 had no confirmation mark, but it did close.
38	CM10.  
39	CM10.  
40	CM10.  
41	CM10.  
42	CM9.  Bottle 6 spigot was bumped and some water lost as CTD was retrieved.
43	CM11.  Bottom nepheloid layer at 590m.
44	CM10.  
45	CM9.  
46	CM9.  
47	CM10.  Small fluorescence peak at ~30m--reason?  Sampled bottle 11.
48	CM3.  No discernible chl max on screen (scales not set right); slightly higher value at 63m (bottle 3).
49	CM1.  
50	CM1.  
51	CM1.  
52	CM1.  Transmission and fluorescence minimum at 11m.
53	CM0.  
54	CM2.  Bottle 12 fired first.  Bottom nepheloid layer at 30m.
55	CM6.  Bottle 1 seemed too warm to be bottom bottle; not sure if bottles fired in correct order.
56	CM8.  No confirmation mark on bottle 8.  Bottom nepheloid layer at 180m.
57	CM11.  Bottles 6&7 accidentally tripped at same depth, so the 24.6 sigma-theta surface was not sampled; however, it was close to the chl max (bottle 11).
58	CM11.  Chl max not a peak, but a broad area from ~40-60m.
59	CM10.  
60	CM10.  Delayed confirmation mark on bottle 8.  Bottle 7 air valve was not tight when CTD brought back up.
61	CM10.  
62	CM10.  Chl and salinity max at ~74m.  Intermediate nepheloid layer at 745-945m; Bottom nepheloid layer.
63	CM10.  
64	CM10.  
65	CM9.  Water in bottle 1 warm; bottle 12 must have fired first.
66	CM10.  
67	CM9.  
68	CM5.  
69	CM0.  No defined chl max.
70	CM1.  No true peak for chl, just increased to bottom.
71	CM1.  Station location changed due to very shallow water; Dissolved oxygen taken for USF from bottle 2.
72	CM2.  
73	CM4.  Bottle 2 tripped first; bottle 1 not tripped.  
74	CM3.  
75	CM7.  
76	CM8.  
77	CM11.  
78	CM10.  
79	CM10.  Top lid on bottle 8 did not seal completely because the cable from bottle 7 was stuck underneath.
80	CM10.  
81	CM0.  No real chl max; highest values at surface & just below.
82	CM9.  No real chl max peak; highest apparent value at bottle 9.
83	CM3.  
84	CM0.  Bottle 2 tripped first.
85	CM4.  Bottom nepheloid layer at bottle 1; intermediate nepheloid layer at bottle 3.
86	CM0.  
87	CM2 .  
88	CM0.  No chl max, highest values at surface.  No mid-water sample taken for PM, xmiss off scale on screen so clearest water could not be identified.  Bottle sequence started with bottle 8.
89	CM0.  No chl max, highest values at surface; decreased to bottom.
90	CM4.  
91	CM9.  
92	CM10.  
93	CM10.  
94	CM11.  Nepheloid layer at ~600-800m.  Bottom nepheloid layer ~850-100m.  Dissolved oxygen taken from bottle 12 for USF.
95	CM10.  No confirmation mark for bottle 3.
96	CM12.  
97	CM12.  
98	CM4.  Transmission off the scale.
