Expocode: 45CE20090206 (CE0903), 45CE201 Ship: R/V Celtic Explorer Woce Line: A07E (part), Rockall Trough Note: This is a resubmission of the A07E (part), Rockall Trough cruise data that I sent to CCHDO on 2009-02-06. Bob Key reformatted the data files and changed some flags. Please replace the old files for these two cruises with these ones. Thank you, Alex.
The CTD salinity versus the laboratory salinity results give an r-squared of 0.9996. The precision was calculated as the standard deviation of the absolute value of CTD salinity minus bottle results and the accuracy was calculated as the average of absolute value of CTD salinity minus bottle results. Precision is 0.004 and accuracy is 0.011. Oxygen winkler samples not taken; DO sensor not calibrated. Contact Triona McGrath
Expocode: None Ship: Celtic Explorer Woce Line: None Note: Attached are two CTD files from cruises to the Rockall Trough. These need to be reformatted and can also be used for Argo calibration. CDIAC has already posted the bottle data files ( http://cdiac.esd.ornl.gov/oceans/Coastal/Rockall_Trough.html ) and has some metadata for these two cruises. Contact for these data is Triona McGrath. Below I attach the note from Triona concerning the CTD data precision/accuracy/calibration bob Hi Robert, Here are the CTD files from the two surveys. The CTD salinity versus the laboratory salinity results give an r-squared of 0.9996 for both surveys. The precision was calculated as the standard deviation of the absolute value of CTD salinity minus bottle results and the accuracy was calculated as the average of absolute value of CTD salinity minus bottle results. For CE10002 both accuracy and precision are 0.008. For CE0903 precision is 0.004 and accuracy is 0.011. We did not take oxygen winkler samples in CE0903 and can therefore not calibrate the DO sensor. We did measure them in CE10002, however the sensor data is not corrected. Is this enough information? Regards, Triona
