Reference: Macdonald, R.W., D.W. Macdonald, and P.S. Munroe. 1977. Oceanographic Data Report. Kitimat Arm, Porpoise Harbour. February 1977. Pacific Marine Science Report 78-24. 61p. -------------------------------------------------------------------------------------- Methods: ---------- Hydrocasts were carried out with 1.7L Niskin P.V.C. bottles at standard depths H.O. Publications 1978). Samples were drawn for oxygen analysis, salinity and nutrients. Each bottle was equipped with two reversing protected thermometers and all bottles at depth greater than or equal to 200m had one unprotected thermometer. In all cases, the depth calculated from the unprotected thermometers was within 3m of the depth recorded on the meter block at the time of sampling. Oxygen samples were drawn first into calibrated 125ml stoppered flashes which were immediately fixed with manganous chloride/alkali iodide solution in accordance with the methods outlined in the Reference Manual for Ocean Chemistry Division Sampling Techniques (1976). Analysis was carried out within one day. Oxygen was determined by Micro-Winkler technique (Carpenter, 1965) in accordance with the procedure outlined in the Ocean Chemistry Division reference manual. The percent saturation was calculated using the formula of Weiss (1970) for oxygen solubility as a function of temperature and salinity Salinity samples were stored on deck in tight stoppered salinity bottles with analysis being carried out after returning to the lab. Nutrients were sampled in duplicates (2 glass, 2 plastic) 20ml screw cap test tubes. They were filled ¾ full and frozen in the upright position immediately after sampling. Salinities were analyzed with an Autolab inductive salinometer with duplicate determination being within ±0.003 Analysis for reactive silicate, nitrate and phosphate was carried out on a Technicon II auto-analyzer using the methods outlined in the Reference Manual for Ocean Chemistry Division Sampling Techniques (1976). -------------------------------------------------------------------------------------- !-1- --2-- --3--- --4--- ---5--- --6-- --7-- --8--- --9--- --10-- !Eve Depth Temper Salini Oxygen: Oxyge Oxyge Phosph Silica Nitrat !nt_ : ature: ty: Dissolv n: n:Dis ate te e !Num Nomin Revers Bottle ed Disso ~ved: !ber al ing lved Satur ! ation !--- ----- ------ ------ ------- ----- ----- ------ ------ ------ *END OF HEADER 3 0.0 6.92 29.84 6.660 290.5 95.1 1.72 34.3 20.2 3 10.0 6.92 29.91 6.600 287.9 94.2 1.70 34.6 20.4 3 20.0 7.00 30.34 6.370 277.8 91.4 1.75 34.8 20.6 3 30.0 7.06 30.47 6.330 276.0 91.6 1.71 33.4 20.5 3 50.0 7.38 30.97 6.100 265.9 88.6 1.74 33.4 20.1 3 75.0 7.82 31.48 5.960 259.7 87.8 1.65 30.6 18.8 3 100.0 8.02 31.81 5.890 256.6 87.3 1.59 28.3 17.8 3 150.0 7.99 32.11 5.380 234.3 79.9 1.65 32.0 19.6 3 200.0 7.83 32.31 4.900 213.4 72.6 1.81 35.9 21.4 3 300.0 7.49 32.58 3.950 172.0 58.1 2.06 44.7 26.0 3 400.0 7.26 32.75 3.470 151.0 50.9 2.78 50.0 28.0 3 500.0 7.13 32.79 3.370 146.7 49.3 2.33 52.5 28.6
