Some of the casts had bottles tripped on the upcast as well. Dissolved Oxygen : Analyzed at onboard ship by Mary O'Brien using an automated version of the Micro-Winkler Technique as described in : "Carpenter, J. H., 1965. The Chesapeake Bay Institute technique for the Winkler "dissolved oxygen method, Limnol. Oceanogr., 10, 141-3. " The titration is done using a Metrohn Dosimat 665 and the end point was detected using a Brinkmann probe colorimeter PC900. The methodology is described by an internal OSAP document (Dissolved Oxygen Determination Methods and Procedures by Bernard Minkley and George Chase). Pooled standard deviation for duplicates : Sp = 0.015 mL/L; number of duplicates was 40. Range of data is 5.035 to 9.432 mL/L Bottle salinity Samples were brought back to IOS and analyzed using a Portasal (model 8410; Serial number 59724) which was standardized using IAPSO standard seawater (P138; conductivity=0.99994; salinity=34.998). Analysis done by Doug Sieberg. Only 3 duplicate salinities were taken. Pooled standard deviation was 0.008 psu. Duplicates were taken from the same niskin bottle. "Nutrients : (silicate, nitrate plus nitrite and orthophosphate)" Samples were analyzed onboard by Linda White. Nutrients were analyzed using Technicon Autoanalyzer II components. Reactive silicate and nitrate plus nitrite were determined according to Technico "Industrial Methods No. 186-71 W and 158-71 W respectively, and soluble " orthophosphate was determined using a modified Technicon method as described "in : Brynjolfson, S.J., 1973. A modification of the Technicon methodology for "determination of orthophosphate in seawater, Paper presented at Water " "Resources Services, Vancouver, B.C." "The method is also described in an internal document : ""Institute of Ocean " "Sciences Nutrient Methods and Analysis"" by J. Barwell-Clarke and F Whitney " 1996. Note : Nitrate plus nitrite values required correction for contamination of the salt wash water. The carboys used for storing the de-ionized water were the source of the contamination. The salt wash water had a higher concentration of nitrate plus nitrite than the surface samples. Each day's correction was determined by averaging the negative peaks from the surface samples and adding the result to the sample values. Medium check standards were run along with the samples for quality control. Most of the samples were analyzed in duplicate and pooled standard deviations were calculated as follows : Silicate: 281 samples were analyzed in duplicate "Pooled standard deviation for 281 pairs : Sp=0.09, n=281" (range for all data is 1.9 to 33.2 uM) Archived data is the average of the duplicates. Orthophosphate: 281 samples were analyzed in duplicate "Pooled standard deviation for 281 pairs : Sp=0.020, n=281 (range for all data is 0.32 to 1.91 uM) The archived data is the average of the duplicates. Nitrate plus Nitrite: 282 samples were analyzed in duplicate "Pooled standard deviation for 282 pairs: Sp=0.07, n=282 (range for all data is 0.0 to 17.2 uM) Archived data is the average of the duplicates. Clorophyll_a:extracted data analyzed by University of Tennessee.
