# This file initialized 4/6/07 
# Data from Rios 4/9/07 and 4/9/07 
# Ship: Hesperides 
# Cruise: 29HE091, FICARAM VI 
# Dates: 4/8-4/24/2003 
# EXPOCODE: 29HE20030408 
# Region: ~24N, very sparse section from 65W to 20W then to Gibralter 
# Chief Scientist: A. Rios 
# 7 full depth stations;  with 24 place Rosette 
# Hydro: Who - A. Rios; Status - final 
# 	Notes: 	 
# Nuts/O2: Who - C.Castro; Status - final  
# 	Notes: estimated O2 error of +/-1umol/kg 
# 	Nutrients frozen prior to analysis. Estimated errors: 
# 		+/-0.05 umol/kg for nitrate 
# 		+/-0.05 umol/kg for silicic acid 
# 		+/-0.01 umol/kg for phosphate 
# 	Methods see: Hansen and Grasshoff (1983), 
# 		Mourino and Fraga, 1985; Alvarez-Salgado et al., 1992 
# TCO2: Who - R. Wanninkhof; Status - final 
# 	Notes: file only has a few samples measured ashore for check 
# TA: Who - A. Rios; Status - final 
# 	Notes: potentiometric titrations with hydrochloric acid to 
# 		a final pH of 4.40 (Perez and Fraga, 1987).  
# 		The electrodes were standardised using a buffer of  
# 		pH 4.42 made in CO2 free seawater (Perez et al., 2000) 
# 	CRM batch 54 analysis implied uncertainty of +/-0.7 umol kg-1 
# fCO2: Who - A. Rios; Status - final 
# 	Notes: surface water only 
# pH: Who - A. Rios; Status - final; S Plus -  up to date 
# 	Notes: SWS@25C 
# 	spectrophotometrically following Clayton and Byrne (1993) 
# 	CRM batch 54 analysis implied uncertainty of 0.0002
