Salinity data shows duplicate sample for bottles 4 and 5, pressure for sampl April 12, 2001 Joe Linguanti ----------------------------- There was a double trip at 800 dbars(sample 83). The second salinity sample was mistakenly entered at 600 dbars, therefore shifting all the values to the next trip depth. The value at the surface trip was not included. To correct for this, the salinity values were shifted down one trip depth and the surface value was entered from the 'Salinity Analysis' sheets. March 8, 2011 Joe Linguanti --------------------------- Due to the double trip mentioned above, oxygen and nutrient values were offset by one depth above 800m. The 600 and 800 meter values were really the duplicate 800 metre bottles. The nutrient and oxygen values were shifted down one trip depth. The surface nutrient values were added from Frank Whitney's spreadsheet and the oxygen surface value was added from the oxygen analysis files. Collection method: ------------------ A rosette, holding 24 ten-litre water samplers, with a CTD was used. Analysis methods: ----------------- Salinity samples are collected in glass bottles and analyzed on Guildline model 8410 Portasal Salinometers which are standardized with IAPSO standard seawater. Oxygen samples are analyzed on an automated Winkler titration system following the procedures of Carpenter (1965). A Brinkmann model 665 Dosimat and model PC910 Colorimeter is controlled by Visual-Basic program to titrate the oxygen samples. Nutrient samples are analyzed fresh on board using a Technicon AAII auto- analyzer following methods described in Barwell-Clarke and Whitney (1996). Chlorophyll was extracted with 90% acetone and analyzed fluorimetrically. References: 1. Carpenter, J.H. 1965. The Chesapeake Bay Institute Technique for the Winkler Dissolved Oxygen Method.
