There is 1.6m of 5cm pipe from the hull to the Moyno 2L6 SSQ pump and the water is then pumped approximately 26 metres through a 3.8cm stainless steel pipe up to the main lab. The system pressure is regulated by a 3.8cm Singer 106RPS valve. In the lab, the seawater flows directly through the Seabird model 21 Sea-cat thermosalinograph and the exhaust goes directly overboard. TSG Data Processing ------------------- There was no loop sampling, intake temperature sensor or flow rate meter. A comparison of temperature and salinity was made with co-incident CTD casts. The temperature in the lab was found to be higher than the CTD casts by a median value of 0.13C degrees. A proxy intake temperature was created by subtracting 0.13 C degrees from the lab temperature. The TSG salinity was lower than that from the CTD salinity with a median difference of about 0.30psu compared to CTD data from 2m and 3m. This difference may be due to small bubbles in the loop. Salinity:T0:C0: Salinity was recalibrated based on the comparison with CTD data. Temperature:Primary - The temperature data from the lab were recalibrated based on comparison with CTD data to create a proxy for intake temperature. Temperature:Lab - These are uncorrected temperature data from the TSG. See document 2018-029-Processing_Report.doc for more details. ---------------------------------------------------------------------------------- WARNING: THESE DATA SHOULD BE USED WITH CAUTION AS THE CALIBRATION OF THE TEMPERATURE AND CONDUCTIVITY SENSORS IS BASED ON A COMPARISON WITH CTD CASTS AND THERE WAS A LOT OF SCATTER IN THAT COMPARISON. DATA ARE REPORTED WITH FEWER SIGNIFICANT FIGURES THAN USUAL TO REFLECT UNCERTAINTY IN CALIBRATION. THE PERFORMANCE OF THE TSG MAY DIFFER WHEN THE SHIP IS IN MOTION. ---------------------------------------------------------------------------------- *CALIBRATION $TABLE: CORRECTED CHANNELS !Name Units Fmla Pad Coefficients !--------------------- --------------- ---- ------ ------------ Temperature:Primary 'deg C (ITS90)' 10 -99 () (-0.13 1) Salinity:T0:C0 PSS-78 10 -99 () (0.3 1) $END !----1----- ---2---- ---3--- ---4--- --5--- ----6----- ----7---- ----8----- -----9----- !
