Brief description

Enhancement of Measurements on Ships of Opportunity (SOOP)- Temperate Merchant Vessel TMV collects data from an autonomous marine monitoring system on the Spirit of Tasmania I to monitor long-term climate change indicators and measures of ecosystem health in Bass Strait surface waters and coastal waters of Victoria and Tasmania. TMV maintains an underway sampling Seabird SBE45 thermo-salinograph (TSG), a Wetlabs combination fluorometer and turbidity sensor (ECO-FLNTU), a GPS were deployed in June 2008 on the Spirit of Tasmania I (VLST) for initial trials. Routine data collection commenced on 28 August 2008. Transects are dependent upon Spirit of Tasmania 1 operating schedule. These are typically undertaken 7:30pm to 7am with subsequent in-port monitoring 7am-7:30pm at Port Melbourne and Devonport docks. During summer and holiday periods the vessel undertakes continuous transects with 2-3 hour turnaround at the ports. Transect data files are available through the IMOS OPeNDAP server. Graphic representation of the temperature, salinity, turbidity, chlorophyll-a by distance are also available.

Lineage

Overview of SOOP data 12 hour - Pt Melbourne (Vic) to Devonport (Tas) daily transects of temperature and salinity, Chl-a fluorescence and turbidity, and GPS location(GGA string). Data collected every second and stored as separate sensor files that are all PC time stamped. Data flow 1. Automated Data collection: SBE45, FLNTU and GPS data streams managed through Labview to sample every second and stamped by PCtime. File naming is: SENSOR_RAW_YY-M-DD_HHMM_.lvm. e.g. SBE45_RAW_08-10-02_1619_000001.lvm Date and time in file is the start of the file. 2. 3-4 week service Download Data Sensor clean-determine offsets for before and after clean.

Data Filtering READ_TSG_SPOT_nextstep.m; READ_FLNTU_SPOT.m; READ_GGA_SPOT.m Reads and removes erroneous data. Re-stiches any data overstamped by PCtime.Writes a clean delimited text file. 4. Data Transfer Raw data and Clean delimited txt files transferred to IMOS. Updated offset and calibration files transferred to IMOS. Updated operational log file transferred to IMOS. 5. Data calculation and offsets Apply data calculation to FLNTU Apply offsets correction to data (if required) Apply additional calibration correction factor (if required) 6. Data subset Subset data records into Bass crossing data and in-port data using change in Latitude/Longtitude to indicate ship movement. Filter out 15 minute freshwater flushes (done twice daily before and after transects) * can be checked using low salinity flag (<20 psu). 7. Data melding Match data files by ctime_YYMMDD.txt to PCtimestamps in GGA, SBE45 & FLNTU files. Apply PCtime drift correction (wrt GPStime in UTC) to melded file 8. Data interpolation and averaging Interpolate across data gaps in GGA, SBE45 and FLNTU with simple linear from 5 points averages either side. Average for two file outputs, 10 sec for voyage (12 hours trip) files and 30 seconds for seasonal (3 month) files. 9 Data Packaging Daily transect Devonport to Melbourne (D2M), Melbourne to Devonport (M2D) and in-port files ("DEV" and "MEL") created in NetCDF format daily plots and monthly contours created. 10. Output to database Seasonal, voyage files and plots provided to database for public access.
