These data provide optical observations that will be correlated with bathymetry and acoustic backscatter imagery to develop a benthic habitat map of Tutuila. Refer to supplemental information for description of instrument and survey.

Data format: | Navigation information are recorded as successive lines in a comma-delimited ascii text file, with a .glo extension. Each line of a GLO file includes the following data: the year, day of year, time, latitude, longitude, water column depth, vehicle depth, layback, and wing angle. The field for vehicle depth does not contain useful data. The field for wing angle is only valid for tows TUT1-TUT4. Each GLO file is imported into MS Excel and saved as an Excel spreadsheet, and additional columns are added to the spreadsheet for each navigation file to enable entry of classification information for each photograph. List of navigation files: tut02001a.glo tut02002a.glo tut02003a.glo tut02004a.glo tut02005a.glo tut02006a.glo in format ASCII |

Navigation information is recorded in ascii text .GLO files which are imported into MS Excel and saved as an Excel spreadsheet. Additional columns are added to the spreadsheet for each navigation file to enable entry of classification information for each photograph. Spreadsheets with classification data entered are combined into a single spreadsheet with the data from each stacked vertically in the order in which the data were collected. The name of that file is " TC0201_TUT-TOAD.xls" and it is also exported as tab-delimited ascii text document with the same name, but with a .txt extension. in format MS Excel Spreadsheet |

Data format: | Camera sled navigation data, converted to a single MS Excel spreadsheet with benthic classification information from still photographs added, is exported as a database (.dbf) format file, and then imported into ArcGIS and saved as a shape file. That file, TC0201_TUT-TOAD.shp and its associated Arc files with the same name but different extensions (.dbf, .sbn, sbx, shp.xml, and .shx) contains an attribute table that includes the classification data. Classifications for each still photograph from all camera sled tows conducted around the island during this cruise follow the scheme described in the file "BenthicHabitatClassificationCodes_Metadata.xls." in format ArcGIS shapefile |
