For casts #110 - #127, the calibration of the Portasal was shifted after analysi on standby values. An offset of -0.002 was applied to the salinity values. ------------------------------------------------------- An altimeter was mounted below the CTD. At the time the deepest bottle was fired the altimeter indicated it was 2.3m above the bottom. -------------------------------------------------------- Samples 515,516,517 - Nutrient samples were left on bench overnight before analysis. 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. Light hydrocarbon samples are collected in glass serum bottles (120 ml) with no headspace, preserved with mercuric chloride, crimped closed and kept cool until analysis back at IOS. The samples are analyzed using a custom purge and trap GC-FID. The seawater is purged with helium and the hydrocarbons are trapped on a Porasil B adsorbent at -190oC. The trap is then isolated, warmed to 40oC and injected into an Agilent 6890 GC with a 60m GasPro column and an FID. Hydrocarbon identification is by retention time and quantitation is by peak area comparison to a commercial standard calibration gas (BOC). The lowest reportable limit is 0.1 nmol/l with a precision of <4%. A value of 0.0 in the data record designates <0.1. References: 1. Carpenter, J.H. 1965.
