| Summary: | Progress Code: completed Maintenance and Update Frequency: notPlanned Statement: Data source: original field data Data processing and quality control: according to current CMAR Data Centre Underway data processing manuals. Salinity and water temperature data was flagged as bad and set to NAN 15:39:10 12-Apr-2007 - 22:11:30 12-Apr-2007 as there was no water flow through the instruments. The seawater pump had not been restarted after the blackout. The depth data was re picked using Sonar Data's echoview software. It is noted that there seems to be a time lag of 30 seconds between the digital data and the re picked depth data' the instrument's time had been checked and had agreed with 'ship' time onboard. The EA500 was externally triggered by a signal from the EM300 swath mapper. Credit Underway data processed by Bernadette Heaney. This dataset contains the Underway (UWY) data collected on Southern Surveyor voyage SS 03/2007. The voyage took place in the Tasman Sea during 13 to 19 April 2007. This dataset has been processed and archived within the CSIRO Marine and Atmospheric Research Data Centre in Hobart. Additional information regarding this dataset is contained in the voyage plan and voyage summary. The standard Underway (=continuously recorded) dataset from a research voyage includes Navigation (NAV), Sounder, Thermosalinograph (TSG) and Meteorological (MET) data. NAV data includes GPS (Global Positioning System) measurements of latitude, longitude, ship's direction and speed. MET data includes atmospheric temperature, humidity and pressure, wind speed and direction, and incident radiation intensity. Data are recorded at 10 second intervals.
