Lower than CTD by 0.016psu. 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 samples are collected in duplicate in calibrated polycarbonate bottles (~330ml), then filtered onto 25mm MFS GF/75 filters at <70mmHg vacuum. The filters are placed in glass scintillation vials and immediately frozen at -20ºC until analysis. The chlorophyll is extracted in 10 ml of 90% acetone for 24h at -20ºC, then brought to room temperature and the extract is decanted and measured using a Turner Designs 10-AU-005-CE fluorometer, which has been calibrated with solutions of commercially prepared chlorophyll.

There remains some doubt about the CTD salinity which may be low by up to 0.004psu. ------------------------------------------------------------------- Comments from secondary file: Q:\Cruise_Data\2004-20\CTD\che\2004-20-0036.nuts ------------------------------------------------ Pressure 1001.5 - NO3 poor peak shape Pressure 802.5 - DIC suspect due to large difference between rinse and sample value. *CALIBRATION $TABLE: CORRECTED CHANNELS !Name Units Fmla Pad Coefficients !--------------------- --------------- ---- ------ ------------ Temperature:Primary 'deg C (ITS90)' 10 -99 () (0.1E-02 1) Salinity:T0:C0 PSS-78 11 -99 (Pressure) (-0.8E-03 0.8E-06) Salinity:T1:C1 PSS-78 11 -99 (Pressure) (-0.137E-01 0.6E-06) $END !--1--- ---2---- --3-- ---4--- 5- ---6---- -7-- ---8---- 9 ---10-- 11--12- 13--14- 15--16-- 17--18-- 19---20-- 21---22-- 2 !Pressu Temperat Trans Fluores Bo Salinity Numb Salinity F Oxygen: F Nitra F Silic F Phosph F Chloro F Alkalin F Carbon: F !re ure: missi cence: tt :T0:C0 er_o :Bottle l Dissolv l te_ l ate l ate l phyll: l ity: l Dissolv l !
