This drowned ridge is located on the Florida Platform in the southeastern Gulf of Mexico about 250 km west of Cape Sable, Florida. This barrier island chain formed during the initial stage of the Holocene marine transgression. These islands were then submerged and left abandoned near the outer edge of the Florida Platform. The southern portion of Pulley Ridge hosts zooxanthellate scleractinian corals, green, red and brown macro algae, and a mix of deep and typically shallow-water tropical fishes. This reef community is in unusually deep water, and its extent and the controls on its distribution were unknown. To address these questions scientists from the U.S. Geological Survey Coastal and Marine Geology Program in cooperation with scientists from the University of South Florida Department of Marine Sciences have completed a detailed mapping of the southernmost 35 km of Pulley Ridge. The area was mapped using multibeam bathymetry, sidescan-sonar imagery, and high-resolution seismic-reflection profiling to define the geologic framework on which the reef is established. Submersible dives, remotely operated vehicle (ROV) transects, and transects of bottom photographs and video were collected to identify the corals and to map their distribution. This extensive suite of data has been compiled and preliminary analysis of the data suggests that the reefs are not tied to the ridge system, but instead are more broadly distributed. Whether reef distribution is controlled by oceanographic conditions or by subtle differences in the substrate that overlies the barrier island system is unclear, and are topics of continued research.This point shapefile represents the locations of each of the bottom photographs acquired during the SUN00030 cruise. Because the shapefile contains information regarding the JPEG bottom photo, a correlation can be made between the JPEG image and it's location in the study area.David C.

For instance, the first part of the first roll of film was placed on CD 2865, while the last part of the last roll of film was placed on CD 2444. Within a roll of film, the CD number increment sequentially.
The separated latitude degrees, decimal minutes and longitude degrees and decimal minutes are recorded for the points where navigation came from the video tapes.
Two depth values exist in the attribute table. One is based on a depth transducer placed on the SeaBOSS system. Because the system is above the seafloor when the image is acquired, this does not reflect water depth - but is probably fairly close. (Attribute: Depth_m_). The other depth attribute (Depth_swat) was derived by extract the grid cell value from the swath bathymetry grid at the point location.20050513Navigation was acquired aboard the boat with a Differential GPS system. This navigation was recorded to a computer, and also as part of the video image. Still photos had a nine digit number recorded on them. The first 3 digits are the image number, the next 2 are the year, the next 2 are the hour, and the final 2 are the minute. The image number recorded on the still photo does not necessarily correspond to the image number given to the digitized image of the photo.Negatives from the still photos are sent to a place in California to be digitized and written to CD. What is returned is a series of CD's, each with about 100 photos on it. A roll of film might span 3 cd's. The naming convention is as follows: IMG0001.PCD, IMG0002.PCD... Each CD starts with IMG0001, therefore there are duplicate filenames, distinguished only by the CD number.An excel spreadsheet was created which included the following information for each photo:
CD#, Roll#, Image# (as appears on the CD), Photo#, year, month, day, hour, minute, dive #. The hour and minute information (read from the photo) could then be used to merge with the navigation data recorded on computer. Navigation is recorded to the second, yet the time on the photos only goes as far as minute. If one photo was taken in a minute, the navigation time used with 30 seconds after the start of the minute. More than one photo per minute, the following seconds of the minute were used:
2 photos: seconds 15 and 45
3 photos: seconds 15, 30, and 45
4 photos: seconds 10, 20, 30, 40
5 photos: seconds 10, 20, 30, 40, 50
This technique was used on dives 13 and 14.
For dives 1-12, navigation was pulled from the video tape based on the presence of the strobe flash associated with a still photo being acquired. This navigation information was entered directly into the excel spreadsheet.The excel spreadsheet was exported as a comma delimited text file and imported into ArcView 3.2a as a table, and subsequently an event theme. Visual inspection of the data points was used to find outliers and fix the navigation in the excel spreadsheet. Based on the time of the photo, and appropriate navigation fix could be pulled from the computer recorded navigation file. In addition to bad fixes, missing navigation information was fixed in the same manner.Once the navigation in the excel spreadsheets was fixed, a new comma delimited text file was exported, imported into ArcView 3.2a as a table, added as an event theme and converted to a shapefile.Additional attribute columns were added and filled.
