# 4/26/95 Initialized README file  
# Ship: Johan Hjort 
# Cruise: 58JH9308 
# Dates: 7/30 - 8/15/1993 
# EXPOCODE: 58JH19930730 
# Region: Greenland-Norwegian Sea 
# 69 stations with 12 place Rosette 
# Chief Scientist: F. Rey (MRI Bergen, Norway) 
# Hydro: Who - F. Ray; Status - not finally corrected 
# 	Notes: Bottom depths from global topography 
# Nuts/O2: Who - F. Ray; Status - first correction done 
# 	Notes:No oxygen data 
# 	On board analysis with Skalar Autoanalyzer 
# TCO2: Who - T.Johannessen/I.Skjelvan; Status - final 
# 	Notes: Few data, but quality appears ok 
# 	Data show significant scatter and are 10-25umol/kg higher than 1981 TTO values 
# 	Ingunn: Samples collected in 50ml serum bottles, poisoned (0.02% HgCl2) capped with butyl rubber septa, stored dark/cold till analysis within one year.  
# 	CRM used; precision <3.0umol/kg; Recommend mark questionable. 
# TA: Who - T. Johannessen/I.Skjelvan; Status - final 
# 	Notes: 	QC difficult due to limited number of measurements 
# 	CRM not used 
# 	Significant scatter, but no obvious offset relative to TTO. 
# 	Ingunn: samples collected in 500ml brown glass bottles, poisoned and screw capped.  
# 	Some analyzed aboard others stored cold/dark till analyzed ashore (<1yr).  
# 	Closed cell potentiometric titration, with Gran linearization calc.  
# 	Calibrated with Tris buffer in 0.5M NaCl. Precision 9-15umol/kg.
