Instructions for
Populating Level 1


  • Level 0

    lowest data form from specific instrument and package, stored data like binary adcp or ascii CTD download or also what is telemetered in real-time (e.g. seahorse and gliders), copy of data from ship cruise CD.
  • Level 1

    Parsed or extracted data from Level 0, maintaining variables by sensor package even if other data like navigation from other sources used, sampled as close to original sampling frequency in time, or depth (some binning may be necessary), and some qc checks, process derived variables, output is format most useful for analysis and contains self-describing data (e.g. netcdf, matlab, MS Excel) -- iterative processing -- such as additional hand edits like file trimming to eliminate sampling when instrument on in position or glider not moving.
  • Level 2

    Field calibration offsets applied to data from Level 1, additional  qc checks, bring values forward even if no calibration applied, output is format most useful for analysis and contains self-describing data (e.g. netcdf, matlab, MS excel).

Ancillary Data

  1. cillat, cillon -- coasts, ilands, and lakes
  2. pbylat, pbylon -- state boundaries (NC, SC, etc)
  3. bdylat, bdylon -- country boundary (US/Canada)

Level 0 Directory Description

/data/long_bay/level0 is divided into platform subdirectories

For more complete descriptions of each cruise see Field Operations. The following descriptions are to help navigate and describe the contents of data in the subdirectories.

  • rvsavannah

  • A subdirectory for each ship cruise contains ADCP, ACROBAT, SCS_CRUISEDATA, and CTD_Stations (profiles and samples)

    • SAV11-27: 8-10 September 2011 – Acrobat tests, some CTD casts, station log sheet needs to be cleaned up
    • SAV11-34: 17-19 October 2011 -- Acrobat tests, test samples for CytoSense (flow cytometer), some CTD casts
    • SAV11-36: 13-16 November 2011 – deployment (and retrieval) of UNC glider (Ramses) near R3 tower; CTD casts; CytoSense samples; net tows
    • SAV11-40: 1-2 December 2011 – deployment of UNC glider (Ramses) near R3 tower; a CTD cast; net tow
    • SAV11-44: 13-16 December 2011 – deployment of UNC bottom mooring at LB3 (171 m); retrieval of UNC glider (Ramses); samples for CytoSense analyses; CTD profiles; net tows
    • SAV12-02: 18-21 January 2012 -- deployment of SKIO Seahorse profiler and bottom frame at LB2 (76 m); deployment of taunt line and bottom frame at LB1 (31 m); 12 CTD stations, starting at 271 m ending at 30 m.  We kept a 5 km spacing from the offshore end until ~45 m.  (Section run from ~1905 EST to 2320 EST on 01/19/12).    
    • SAV12-03: 24 January  - 02 February, 2012 -- Both gliders deployed; Acrobat (towed package) surveys of 3 cross-shelf sections (25 km along-shelf spacing, mid-shelf to upper slope); CTD profiles for hydrography, bio-optical, oxygen; station sampling for chlorophyll, nutrients, flow cytometry;

    • SAV12-05: 13-26 February 2012 -- Both gliders turned-around.   Survey work was conducted using the towed Acrobat package and CTD station section from upper slope to shelf.  Deck incubation experiment for primary production, station sampling for various properties.  Feb 18-26 weather and shaft failure forced ship to return to SkIO along the coast. 
    • SAV12-11: 13-23 March 2012 -- Both gliders turned-around (at LB2).   Acrobat surveys, upper slope to outer shelf CTD surveys, station sampling for water samples and primary productivity experiments (deck incubations and “photosynthetron”).  Attempted to survey a subsurface bloom in the mid-shelf (apparently Phaeocystis).   Acrobat tow cable failed over upper slope and sank -- maybe located for later recovery. 
    • SAV12-14: 02-05 April 2012 -- Recovery of moored instrument packages at LB3, LB2, LB1;  Recovery of gliders;  CTD section from upper slope to outer shelf (stations at 5 km intervals, LB+60 to LB+30, also at LB2 site), with samples for nutrients at selected stations/depths, some chlorophyll samples; Inter-calibration of the ECO FLNTU fluorometer/turbidity instruments after recovery of moorings (mounted on CTD/carousel for co-located sampling at two depths). 
  • ramses

  • A subdirectory for each glider deployment contains comm  [1]  (from-glider binaries, logs, and ascii) and store [2] data (science and flight binaries and ascii)

    • 2011_11: 14-15 November 2011 – aborted sea trial, held at depth by a Remora (?), wire burned
    • 2011_12: 02-15 December 2011 – first sea trial with panty hose, and operational test of GCCS and piloting tools
    • 2012_01: 26 January - 14 February 2012 -- profiled over LB3 from Jan 28 until Feb 09 when strong SW filament current pushed ramses SW about 40 km;
    • 2012_02: 15 February - 14 March 2012 -- Profiled on LB3; Around March 1 Gulf Stream pushed up onto the shelf taking both gliders NE along the GS edge.  Ramses
    • 2012_03: 16 March - 03 April 2012 -- Deployed near LB2; Profiled near LB2 then halfway between LB2-:B3 and then over LB3; onshore cross-section to LB1 as NE currents from strong SW winds blew through then back out to LB3 after subsided; Profiled LB3 until recovered on 03 Apr.

  • pelagia

  • A subdirectory for each glider deployment contains comm  [1]  (sbd and tbd) and store [2] data

    • 2012_01: 26 January - 14 February 2012 -- first sea trial, no transects along cross shelf line; but profiled on a wondering path staying up on the shelf within the study area;  a large (3 foot) loggerhead turtle was riding herd over pelagia when recovered on 14 Feb.
    • 2012_02: 16 February - 08 March 2012 -- Wondering transects, until Around March 1 Gulf Stream pushed up onto the shelf taking both gliders NE along the GS edge.  Pelagia was recovered off Cape Lookout aboard the Capt Stacy III (Head Boat) out of MHC on 08 March. Returned to SKIO via land.
    • 2012_03: 16 March - 04 April 2012 -- Deployed near LB2; Transects between LB1 and 1/2 point to LB3. Recovered off SW of LB1 on 04 April.

    Other Access Points

    The links above are provided to help explain and navigate the directory structure.  However you can access the data directly via http (without NCCOOS web framework). The disk where the data are located is mounted on several web-accessible machines.   The direct HTTP  links available are:

    If you require direct ssh, scp or sftp, please contact Sara Haines or Chris Calloway.


    1. comm -- data received via communication during mission -- This data is transmitted in real time. via Iridium to dockserver (tbd, sbd, and ascii equivalents).
    2. store -- internally stored data -- This data is copied after glider recovery.  This is data from both science and glider persistors (tbd, sbd, dbd, ebd, and ascii equivalents). The store data is further broken down by the two glider persistors:
      • science -- manages scientific instrument sampling Data from the science persistor includes LOGS (ebd, ndb, nlg) and SENTLOGS (tbd) and config. 
      • flight -- flight control and monitoring of the glider.  Data from flight persistor includes LOGS (dbd, mdb, mlg) and SENTLOGS (sbd) and config, mafiles, and missions.
