Source: These data were sent to NCEI by the NOAA Office of Exploration on three 
MiniDV tapes.


Action(s):
Video data on each Mini DV tape was transferred into Apple Final Cut Pro, from 
which a high-resolution file in the .dv format was exported and copied into the 
subdirectory data/0-data/Cruise_ID-year/.


The .dv files were then transcoded with the command line utility ffmpeg to 
create low-resolution access files in the .mov format, which were copied into 
data/1-data/Cruise_ID-year/.

Files:
about/
This directory contains files generated by NCEI with ancillary information 
about the data submission.

0036668_lonlat.txt - 
  Contains sample locations for these data.  Each row contains the geographical
  position where these data were collected (longitude in the left column and
  latitude in the right column, both in degrees).  NCEI may have corrected 
  geographic positions that seemed to be in error when generating this file.  
  However, NCEI did not change the original data files under the directory 
  data/0-data/.

data/0-data/Canaveral_2005
This directory contains the high resolution videos which were transferred to 
.dv format from the originally submitted MiniDV tapes. 

 JSL1-4910-1_2.dv
 JSL1-4910-2_2.dv

These files use the following  naming convention:
vehicleID_diveNumber_tapeJ_ofN 

data/1-data/Canaveral_2005
This directory contains the low resolution video files which were transcoded by 
NCEI to the .mov format from the NCEI-created .dv files.

  FloridaCoastDeepCorals2005_Dive4910_Tape01_Low.mov
  FloridaCoastDeepCorals2005_Dive4910_Tape02_Low.mov

Unlike the high-res video files in 0-data/, these transcoded files use an 
alternate naming convention for physical media that is consistent with other, 
later video data from the same data provider:
 CruiseID_DiveID_TapeID_Low.mov

In this archival information package, the following mapping indicates which .dv 
file directly corresponds to an equivalent .mov file:

  0-data/Canaveral_2005/JSl1_4910_1_2.dv = 
  1-data/Canaveral_2005/FloridaCoastDeepCorals2005_Dive4910_Tape01_Low.mov


  0-data/Canaveral_2005/JSl1_4910_2_2.dv = 
  1-data/Canaveral_2005/FloridaCoastDeepCorals2005_Dive4910_Tape02_Low.mov
