Gaps in sequential photo numbers exist. If camera was triggered accidentally on deck or picture did not come out, it was deleted.
Only the subset of bottom photograph locations occupied during the R/V Connecticut survey 07003 within the Duxbury to Hull survey area have been included in this spatial dataset. Seventy-seven stations were occupied within the study area between Duxbury and Hull. A total of 184 sampling sites were occupied during survey 07003. The bottom photograph locations that are not included in this report are from sites south of Brant Rock, Massachusetts and will be published in a subsequent data release focused on Cape Cod Bay. Any bottom photographs taken in water column or were otherwise not usable were deleted.

Process_Description:
One hundred eighty-four target stations were occupied aboard the R/V Connecticut (USGS survey 07003) with the large SEABOSS (Blackwood and Parolski, 2001) that was equipped with a Van Veen grab sampler, a digital still camera, and a video camera. Seventy-seven of those sites are within the Duxbury to Hull 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 on each Julian Day file creating a comma separated value (CSV) ASCII text file to parse for the GPGGA navigation string and reformatted the file 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 adjustment 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. Camera time for the first Gregorian Day (Sept 7) of surveying was approximately 1 hour off. This was corrected for subsequent survey days however the camera time varied from 5 to twenty-seven seconds from the GPS during other parts of the survey. On the last day of surveying the month was incorrectly set on the camera. Microsoft Excel was used to manually make these time adjustments. The following is a list of offsets (not including the 1 month shift for photos taken in "Download 4": > Download 1, 306 photos @ 4:00 UTC JD251 after sta33 (EOGD 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 (EOJD 251), average offset = photo ahead by 11 sec, original photo directory 090807 > Download 3, 372 photos @ 4:00 UTC JD253 after sta131 (EOGD 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 (EO 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 (DH_SeabossTrackline.shp). The 656 photos from within the Duxbury to Hull 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). 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'), 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. 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.
