Altimeter added on Cast 15. Oxygen to match with bottle data is taken from the downcast, matching on density for the upper 600db and matching on pressure for depths greater than 600db. Temperature was calibrated with the pre-cruise calibrations. Conductivity, Oxygen and Fluorescence were calibrated to water samples. Salinity was recalculated using the corrected conductivity. Transmissometer and Altimeter are not calibrated. Fluorometer notes: Calibration with bottle data performed using bottle chlorophyll values between 0.025 and 0.6 mg/m3. The number of observations used were 75 out of 93 with a standard deviation of 0.02 in the residuals. Coefficients used: Slope: 1.4585, Bias -0.0026. Downcast CTD Fluorometer with bad values replaced with good upcast values for casts 19, 20 30, 34, 37 and 40. Remaining bad data replaced with -99. Oxygen Calibration: Casts 1 to 50 (full cruise) oxygen was calculated from oxygen voltage using the Seabird Owens-Millard algorithm using coefficients: boc: 0, tau: 0, tcor: 0.0015, pcor: 1.3500e-004, voffset: -0.4716, soc: 0.3753. A lag of -6 seconds was applied to oxygen voltage in Seabird data processing step Align. Chemistry Sampling and Analysis Methods: --------------------------------------- For full details see report "Physical and Chemical Data from the Canada Basin, August 2004" cited below. Salinity samples were collected in 200 mL type II glass bottles with disposable plastic inserts and screw caps. Onboard, samples were analyzed in a temperature-controlled lab on a Guildline AutoSalinometer Model 8400A (SN: 49463), which was standardized with IAPSO standard seawater. Onshore, samples were analyzed on the Guildline PortaSalinometer #59724, which was standardized with IAPSO standard seawater. Oxygen samples were collected in glass flasks and analyzed on board on an automated Winkler titration system following the procedures of Carpenter (1965). The titration was performed with a Metrohn Dosimat 665 and end point was detected using a Brinkmann probe Colorimeter PC910. Software written at the Institute of Ocean Sciences, NewAutoOxy.exe, was used to calculate dissolved oxygen (ml/L). Nutrient samples (nitrate plus nitrite, silicate and orthophosphate) were collected in glass and polystyrene test tubes. Samples collected in the Canada Basin were analyzed fresh on board, using a Technicon AAII auto-analyzer following methods described in Barwell-Clarke and Whitney (1996). Samples collected from 15 stations in the Canadian Archipelago were frozen and analyzed on shore using the same method. Total Chlorophyll-a (>0.7um) samples were collected into insulated plastic coolers and analyzed on board. 500 ml samples were filtered onto 25mm GF/F filters using low vacuum filtration. The filters were put into scintillation vials with 10 ml of 90% acetone, labeled and put into a 4 degree C cooler for 24 hours, then brought to room temperature for an hour and chlorophyll-a and phaeo-pigment levels were measured with a Turner Designs fluorometer (model 10-AU-005). The sample was acidified with 1.5N hydrochloric acid to obtain the phaeo-pigment reading. Oxygen Isotopes Samples were collected into 30 ml (approximate) glass vials. Once at room temperature, the caps were retightened and wrapped with electrical tape for storage. Samples were analyzed in May 2005 at Oregon State University using the H2O-CO2 equilibration method on a Finnigan MAT mass spectrometer. Barium samples were collected in ~20 ml plastic vials. Once at room temperature the caps were retightened for storage. Barium was determined at Oregon State University, using isotope-dilution and a VG Thermo Excel Inductively coupled quadrupole mass spectrometer as previously described with minor modifications (Falkner et al., 1994). Phytoplankton and bacterioplankton were collected in 2 ml capacity cryogenic vial and immediately fixed with 0.2 ml of 10% paraformaldehyde by vortex mixing. Samples were maintained for at least 15 min at laboratory temperature to allow fixation, and then stored at -80 degree C until analysis at the Bedford Institute of Oceanography. Cell concentrations of picophytoplankton, nanophytoplankton, and bacterioplankton (i.e. non-autofluorescent picoplankton) in thawed samples were analyzed by flow cytometry (Becton Dickinson FACSort) following protocols in routine use (Li and Dickie, 2001).
