Sample Number 196: Dimethyl_Sulphide:Bottle - instrument problems - data not reliable. Sample Number 340: Salinity:Bottle - sample bottle leaking - outlier in comparison with Salinity:CTD. Sample Number 574: All samples - it is not certain which Niskin bottle was sampled. Sample Number 598: Chlorophyll:Extracted:Bottle - filtered 18 hours after collection. Sampling Methods are expressed with the following codes ------------------------------------------------------- ROS - Rosette sample collected from approximately 5m depth. LOOP - Sample drawn from a pumped seawater supply provided to the ship laboratory from a nominal depth of 4.5 metres. Analysis methods: ----------------- Chlorophyll samples were analyzed at sea using a Chemistry Turner Designs 10AU fluorometer which was calibrated on May 12, 2009 using pure chlorophyll a. Chlorophyll precision was determined by analyzing replicate samples drawn from one Bottle. For details see file 2009-09_CHL_presicion.pdf. Oxygen samples were analyzed at sea using an automated titration system consisting of a Brinkman Dosimat (model 665) and a PC 950 Colorimeter. For information on precision see file 2009-09_OXY_duplicates.pdf Salinity samples were collected in glass bottles and analyzed at IOS on a Guildline model 8400B Autosal standardized with IAPSO standard seawater. Samples from some casts were analyzed at sea on a Guildline Portasal; there are comments attached to those samples and all were flagged "4". See file 2009-09_SAL_duplicates.pdf for information on Autosal precision. Nutrient samples were collected in plastic tubes and analyzed fresh at sea using an Astoria autoanalyzer following methods described in Barwell-Clarke and Whitney (1996). For details on nutrient duplicates and precision see file 2009-09_NUT_precision.pdf. The minimum detectable level for DMS is 0.10 nM, so “0” values should be interpreted as <0.10. For details on the collection and analysis of the DMS data see file 2009-09_DMS_Report.pdf. References: 1. Carpenter, J.H. 1965.

In August 2010 a study was made of transmissivity that led to a decision to apply post-processing corrections to all cruises between March 2008 and June 2010. Transmissivity data from this cruise were corrected by multiplying the original values by a correction factor, which was based on assumptions that deep offshore transmissivity from a June 2009 cruise should be about 62%/m and that drift was linear with time between March 2008 and July 2009. The corrections produced reasonable results for all cruises in that time period. For details on how the correction factor was derived see Transmissometer_1005DR_Corrections.pdf These data should be considered estimates. ********************************************************************************* $REMARKS Data quality is expressed with the following flags ---------------------------------------------------------------------------- 1 = Sample for this measurement was drawn from water bottle but not analyzed (not normally used). 2 = Acceptable measurement (not normally used). 3 = Questionable measurement (no problem observed in sampling or analysis, but value is not trusted, nonetheless; includes outlyers). 4 = Bad measurement (known problem with sampling or analysis, but not serious enough to completely discard the value). 5 = Not reported (lost sample; unredeemably bad measurement). 6 = Mean of replicate measurements. 7 = Manual chromatographic peak measurement. 8 = Irregular digital chromatographic peak integration. 9 = Sample not drawn for this measurement from this bottle (not normally used). ---------------------------------------------------------------------------- $END !-1- ---2---- --3--- -4-- ----5----- --6-- ---7--- ---8--- --9--- ---10--- ---11--- ---12--- ---13--- ---14--- --15-- ---16-- --17-- ---18--- 19 --20-- 21 --22- 23 --24-- 25 --26- 27 --28-- 29 --30-- 31 !Eve Station_ Sample Samp Date:UTC TIME: Latitud Longitu Pressu Temperat Salinity Sigma-t: Transmis Oxygen: Oxygen Fluores PAR: Salinity Fl Oxygen Fl Nitra Fl Phosph Fl Silic Fl Chloro Fl Dimeth Fl !nt_ Name _ le_ UTC e de re:CTD ure:CTD :CTD CTD sivity: Dissolve : cence: CTD :Bottle ag : ag te_pl ag ate: ag ate: ag phyll: ag yl_ ag !Num Method Numb CTD d:CTD: Dissol CTD ~o Dissol ~o ~Nitr ~o Bottle ~o Bottl ~o Extrac ~o Sulphi ~o !ber er Volume ved:CT tt ved: tt ite:B tt tt e tt ted: tt de: tt !
