Abstract | Arc-en-Sub 2022 cruise ROV VICTOR Navigation (M. Andreani & J. Escartin) The onboard data extracted from the ROV data streams (shipboard navigation), and the post-processed navigations, with files for each individual dive, are also provided for reference. For the final navigation, files with a sampling rate of 1-second and a subsampled 1-minute record are provided. Corrections include: ########################################### Files: AES_ROV_Dives.xlsx ########################################### We provide a 1-s and a 1-m final navigation file, combining all dives in each case, that will be considered as the reference navigation for the cruise, and will provide the location for all samples and observations. The navigation files are named: These files are obtained from the IFREMER renavigated files for the vehicle position, and from shipboard data for other parameters. Corrections include removal of flags (use of NaNs instead), interpolation for short data gaps in the processed files, and the use of shipboard navigation data to fill larger data gaps from the processed files. The vehicle depth and altitude are those from the ROV streams. Both files are text tables with the following columns: ########################################### Individual navigation and ROV data files were created onboard and are provided in a single compressed file: ARCENSUB_Victor_ShipboardNav.zip This file contains a navigation and data file for each dive, named AES_VXXX_2205DDHHMM_victor_nav_sensors.txt where XXX is the absolute dive number, followed by the year (22), month (05), day (DD), hour (HH) and minute (MM) The columns, given in the first line of the file, include at a 0,5s interval: #YEAR MONTH DAY HOUR MIN SEC
########################################### Processed navigation files provided by IFREMER, together with a report, are provided in a single compressed file: ARCENSUB_Victor_ProcessedNav.zip This file includes: - The processing report: 22_128-Compte-rendu-traitement-Mission-AES-V.pdf - Navigation files for each dive named AES_V_XXX_YY.txt where XXX is the absolute dive number and YY the incremental cruise dive number - Map of the navigation for each dive named AES_V_XXX_YY.jpg (naming as above) Each navigation file includes the following parameters acquired every 0.5s: date time |
