A.2  CRUISE SUMMARY

The Canadian Naval Auxiliary Vessel ENDEAVOUR left Esquimalt on March 26, 1992 
in the midst of a long period of mild spring weather with six IOS scientific 
personnel and one researcher from UBC. Fig. 1 gives the station locations.

The program of planned measurements is shown in Table 1 and included sampling 
of pCO2, TCO2, alkalinity, 13C and oxygen isotopes in addition to the WOCE 
repeat hydrography: CTDs and bottle casts for temperature, salinity, nutrient 
and oxygen analyses. Plankton net trawls, productivity studies and surface 
water samples were undertaken as part of IOS's Climate Chemistry projects 
overseen by Mr. Jinping Wu. Servicing and redeployment of sediment trap 
moorings were scheduled for Station P and the Alaska Gyre station at 550 N and 
1450 W and a free-drifting sediment trap was planned for Station P. Additional 
data down line R (50° 55.7' N, 143° 01' W to 51° 23.5' N, 133° 49.6' W) and 
along connecting cruise tracks was to be undertaken as time permitted.
The first night out saw winds to 40 knots so that Stations P01 and P02 could 
not be occupied safely. However, the morning of the 27th was good enough and 
data collection started at Station P03, continuing to P14 where once again 
strong winds and high seas prevented over-the-side operations. Data collection 
continued from Stn. 15 to Station P where a full depth cast with a full suite 
of chemical samples was obtained using 10 litre Niskin bottles. A drifting 
productivity experiment was deployed and the free drifting sediment trap was 
put out. Attempts to interrogate the sediment trap mooring at Stn. P were 
unsuccessful so the release signal was sent and a surface search was done, 


The ship proceeded north toward Stn. AG but analysis of the problems with the 
Stn. P mooring showed that the battery voltage in the deck unit was too low for 
reliable operation. The ship was therefore turned around and another attempt to 
recover was made in the morning of April 3. After many attempts, the deck unit 
successfully actuated the release and the mooring was recovered around 1900 Z. 
Although only one bottle of sediments was collected, the sediment trap was 
successfully retrieved and prepared for deployment. Data collection along the 
line to Stn. AG was completed. The AG mooring was recovered and the instruments 
and release from Stn. P were moored in its place. The ship then returned to 
Stn. P, completed another bottle cast and deployed a sediment trap mooring 
using components from Stn. AG and some additional sediment traps to complete 
the array. The cruise continued down Line R and approached the southern tip of 
the Queen Charlotte Islands along line J. On the return trip to Esquimalt, 
Stations P01 and P02 were picked up and the ship docked at 0900 hrs on April 
13, 1992.

Cruise Track

Three straight sections were completed. Line P, from the mouth of the Straits 
of Juan de Fuca on the Canadian West Coast (48° 34.5' N, 125° 30' W) to Station 
P (50° N, 145° W). from Station P to Station AG (to 55° N along 145° W).  Lines 
R and J, from Station P to the southern tip of the Queen Charlotte Islands (48° 
34.5N, 125° 30 W).

traps(FDSTAR) and 12-hour duration primary productivity arrays were deployed 
and recovered.

At Station AG, 1 sediment trap mooring was recovered and re-deployed. At 
Station P, 1 sediment trap mooring was recovered and re-deployed.

          All the data that IOS has submitted either for PR05 & 
          PR06, or for P1W and P15N can be made available to the 
          public.  Most of these data are already archived at MEDS 
          and published.  an appendix to the Deep-Sea Res II volume 
          (46) for Canadian JGOFS contains the PR06 T/S, nuts and 
          oxygen data for the upper 1000 m for the 1995-97 period.

          It has always been our plan that data would be available 
          within two years of collection.

06/18/02  Uribe           CTD/SUM       Website Updated  Reformatted 
          data online  CTD and Sumfile have mismatching 
          station/casts. CTD have increasing cast numbers. Sumfile 
          was modified only for the purpose of the conversion to 
          match the values from the CTD files. The cast types CTD 
          from the sumfile were the lines used to match the CTD. For 
          more details please see the README in the original 
          directory. CTD inventory file and netcdf files were made 
          and put in corresponding directory.
          
07/22/02  Uribe           CTD           Website Updated  Cast 
          numbers changed to match SUM file  The increasing cast 
          numbers in the CTD files were changed to 1 to match the 
          sumfile. These changes were made previously for the 
          exchange conversion but it was now decided this change 
          should be kept in the data that's online.
