Gaps in sequential photo numbers exist. If camera was triggered accidentally on deck or picture did not come out, it was deleted.
A total of 1,329 bottom photographs were taken during survey 07003 covering both the Duxbury to Hull and northern Cape Cod Bay survey areas. Only the 673 bottom photograph locations collected within the northern Cape Cod Bay survey area are included in this spatial dataset. The bottom photographs collected north of Brant Rock, Massachusetts are published in a previous data release (2009-1072) focused on the Duxbury to Hull survey area (Barnhardt and others 2010). Any bottom photographs taken in water column or were otherwise not usable were deleted.

Process_Description:
Target stations were occupied with the large SEABOSS (Blackwood and Parolski, 2001) that is equipped with a Van Veen grab sampler, a digital still camera, and a video camera. One-hundred nine stations are within the northern Cape Cod Bay survey area. The digital photographs were downloaded from the camera and backed-up to a laptop and hard-drive four times during the sampling survey.

Process_Description:
DGPS navigation was logged through a Microsoft HyperTerminal (version 5.1) session on a Dell Latitude D820 laptop computer running Windows XP, SP2. Log files were saved for each sampling watch then reformatted into log files by Julian Day (e.g. nav_sda.251) during post-processing. The AWK script HT_doGPGGA.awk was modified accordingly for each Julian Day and run (using GNU AWK version 3.1.6) on each Julian Day file creating a comma separated value (CSV) ASCII text file. This file was parsed for the GPGGA navigation string and reformatted for input to the Python ground-truth toolset. The individual Julian Day navigation files were concatenated into a single navigation file for the entire sampling survey (07003_allnav_gpgga_formatted.csv). > cat gpgga_out* > 07003_allnav_gpgga_formatted.csv

Process_Description:
Manual adjustments were done to account for a number of time offsets between the time recorded in the JPEG EXIF time "Date Picture Taken" and the GPS time as verified by the SEABOSS video. The date and timestamp on the video is acquired directly from the GPS. The camera time generally varied from 5 to twenty-seven seconds from the GPS during parts of the survey. However, on the first day of the survey, the camera time was almost 1 hour off and on the last day of the survey the month and year were incorrectly set on the camera. Microsoft Excel 2003 was used to manually make these time adjustments in the table that will be used in the next step to create the shapefile. The following is a list of offsets (not including the 1 month and 1 year shift for photos taken in "Download 4"): > Download 1, 306 photos @ 4:00 UTC JD251 after sta33 (end of Gregorian Day 9/7), average offset = photos ahead by 59 min 10 sec (adjust -3550 seconds), original photo directory 090707 > Download 2, 316 photos @ 23:50 UTC JD251 after sta91 (end of Julian Day 251), average offset = photo ahead by 11 sec, original photo directory 090807 > Download 3, 372 photos @ 4:00 UTC JD253 after sta131 (end of Gregorian Day 9/9), average offset = 8 sec for JD252 and 5sec for JD253, original photo directories 090907 and 091007a > Download 4, 344 photos @ 8:30 UTC JD254 after sta175 (end of SEABOSS ops), average offset = photos ahead by 24 sec, original photo directories 091007b and 091107

Process_Description:
In ESRI ArcMap (version 9.3), a spatial join was done to merge the attributes of the bottom photograph locations shapefile (07003_BP_Feb4.shp) with the SEABOSS tracklines shapefile (CCB_SeabossTrackline.shp). The 673 photos from within the northern Cape Cod Bay survey area were selected and XTools Pro (version 5.3.0) for ArcGIS desktop was used to reorganize, delete unnecessary fields and add new fields to the point shapefile's attribute table (Table Operations - Table Restructure). This created a new shapefile of the bottom photograph locations within the Cape Cod Bay survey area. Table attributes for the survey ID ("SURVEYID'), device used to collect the data ('DEVICEID'), survey vessel name ('VEHICLEID'), and year ('YEAR') were added and/or populated using the table editor in ArcMap (version 9.3). The attributes for time ('TIME'), photo name ('PICNAME'), latitude ('LAT'), longitude ('LON'), Julian day ('JULDAY'), hotlink location ('HOTLINK') and SEABOSS station number ('LINENAME') were already populated.

Process_Description:
Edits to the metadata were made to fix any errors that MP v 2.9.30 flagged. This is necessary to enable the metadata to be successfully harvested for various data catalogs. In some cases, this meant adding text "Information unavailable" or "Information unavailable from original metadata" for those required fields that were left blank. Other minor edits were probably performed (title, publisher, publication place, etc.). The metadata date (but not the metadata creator) was edited to reflect the date of these changes. The metadata available from a harvester may supersede metadata bundled within a download file. Compare the metadata dates to determine which metadata file is most recent.
