Notes: PHOTOS Still photos were acquired from a remotely operated digital camera mounted on a towed camera sled. Photos were taken at the top of every minute, and when significant features were noted. Photos in this KML are reduced to 1/4 of the original resolution. BATHYMETRY AND SHADED RELIEF Shaded relief and bathymetry were generated from multibeam bathymetry data collected in 2001-2002 (survey H11039), downloaded from Illumination azimuth is 300 degrees with an angle of 45 degrees from horizontal. Pixel resolution is 5 meters. VIDEO OBSERVATIONS Video observations were initiated at the top of each minute (startOfEnt field) and recorded for the first ten seconds of each minute. This feature class has the following fields: StartofEnt: (UTC) Date when the entry was created Time: (UTC) Time when the entry was created Latitude: Latitude of observation Longitude2: Longitude of observation Heading: Ship heading at time of observation Course: Course (over ground) at time of observation LogEntry: Information recorded in digital log Req1: Primary substrate Req2: Secondary substrate Req3: Slope category Req4: abiotic complexity Req5: biotic complexity biology fields - The following fields record biota identified in video observations along this trackline. a zero indicates no observation, while a 1 indicates an observation. Biota categories observed along for camera line 17 & 18 include: anemon_sol bivalve bryozoan drift_weed fish fish_a hydroid kelp shell_scat tube_worm tunicate LOG ENTRIES Log entries record data entered into the electronic log. These entries typically record events not captured otherwise, such as start and end of tracklines, start and end of tapes, and other events. SHIP TRACKLINE Shows the ships track during the period when camera and video data were collected.
