Waldrun. The data were prepared in a spreadsheet that was then converted to IOS Header format. The comments on sampling and analysis below are taken from the document. ---------------------------------------------------------------------------------------------------- SAMPLING METEHODS AND ANALYSIS Water samples were taken with Nansen bottles at the standard depths of 2, 4, 6, 10, 15, 20, 30, 50, 70, 100, 150, 200 and 250 metres or to the maximum depth the bottom would allow. Surface samples were collected with a bucket. Temperatures were obtained, when possible, with paired reversing thermometers at each depth. depth. Surface temperatures were measured in a bucket with a standard 0-30 C surface thermometer. These data were supplemented by continuous temperature records with depth using a bathythermograph. At each station, a Secchi disc reading was taken as a measure of water transparency. Samples were taken at each depth for salinity, dissolved oxygen, pH and alkalinity determinations. Dissolved oxygen, pH and alkalinity determinations were carried out immediately on board ship. Salinity samples were collected in 10-12 oz medicine bottles, sealed tightly with corks and wax or with screw caps lined with polyethylene sealers, and returned to the base laboratory for salinity determination. Salinities were carried out on an Australian (CSIRO)-type of inductive salinometer. Dissolved oxygen was carried out by the modified Winkler method. pH and alkalinity were determined with a Model G or Model GS Beckman pH Meter, according to the procedures described by Strickland and Parsons (1965). Details of the other analyses, are given in the section on observations and methods. ---------------------------------------------------------------------------------------------------- EXPLANATIONS OF CHANNELS Station Designation: The stations are designated by number consecutively in the order they were usua taken. Prefix letters M, Q, O, K, and P of the numbers designate stations in Muchalat Inlet, Quatsin Sound) Cousins Inlet, Kitimat Arm, and Prince Rupert Harbour area, respectively. Depth (of bottom): Sounding obtained from the echo sounder and/or from bottom sampler or lead weight and meter block. Depth (of sample): Distance in metres from the water surface to the sampling bottle, as measured on the meter block. T (C): Temperatures obtained from reversing thermometers are reported to the nearest 0.01 degree Celsius. Surface temperatures measured with an ordinary 0 to 30 C surface thermometer are accurate only to the nearest 0.1 C. Salinity (‰): Salinity expresses the total salt content of the water in parts per thousand (‰) and w usually determined on a salinometer at the base laboratory. These data have an accuracy of ± 0.01‰. Samples with very low salinities were titrated with an accuracy of ± 0.05‰. Sigma_t: Density term at atmospheric pressure and in situ temperature, as defined by: (Density - 1) 1,000. It is a function of salinity and temperature and was determined from nomographs prepared by the U.S. Hydrographic Office. Dissolved Oxygen_mg/L: Concentration of dissolved oxygen in milligrams per litre of water. For conversion to mg-at/l divide by 16 and to mI/l multiply by 0.7. Dissolved Oxygen (% Sat.): Percentage that the observed concentration bears to the total concentrati when the water is saturated with dissolved oxygen at the in situ salinity and temperature. Defined b (Observed concentration ÷ Saturation concentration) x 100 The saturation concentration, as a function of salinity and temperature, was obtained from a nomograph prepared by Tully (1949) from tables given by Whipple and Whipple (1911) . pH: Hydrogen-ion concentration in pH units (1-14) measured to the nearest 0.01 unit on a pH meter an corrected for the in situ temperature and salinity. A Beckman pH Meter (Model G-2 or GS) was general used, with samples first brought to room temperature. The pH was measured within 12 hours whenever possible; but in case of delay, samples were held in a dark cooler. Alkalinity - Total: The number of milliequivalents of hydrogen ion neutralized by 1 litre of sea wat 20 C. It was determined by measuring the pH in 100 ml of sea water treated with 25 ml of 0.01 N hydrochloric acid, using a Beckman pH Meter (Model G-2 or GS) in the laboratory, with samples first brought to room temperature, usually within 12 hours of collection. Alkalinity - Carb: The number of milliequivalents of hydrogen ion neutralized by 1 litre of sea wate C in converting carbonate and bicarbonate ions to carbon dioxide. It was evaluated from the total alkalinity, using the tables given by Strickland and Parsons (1965). !--1--- --2--- --3--- --4--- --5--- --6--- --7--- --8--- --9--- --10-- --11-- !Depth Temper Salini Sigma- Oxygen Oxygen Oxygen Oxygen pH Alkali Alkali ! ature: ty: t : : : :Disso nity: nity: !
