Abstract:
Pulley Ridge is a series of drowned barrier islands that extends almost 200 km in 60-100 m water depths. 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.
Purpose:
This polyline shapefile was generated to indicate the location of the Sustainable Seas Expedition dives in the Pulley Ridge area aboard the NOAA ship Gordon Gunter.

Lineage:
Process_Step:
Process_Description:
Converted the SSE navigation from excel spreadsheets to individual point shapefiles for each dive. This was accomplished by exporting the necessary records to a text file and then loading those as an event theme into ArcView and saving as a shapefile.
Process_Step:
Process_Description:
A line shapefile was then generated connecting the points in the order of navigation acquisition. This was done to help more readily spot obvious outliers.
Process_Step:
Process_Description:
In some cases, running a filter over the points helped remove outliers. (This is discussed in the next process step.) Some files had major outliers that needed to be deleted prior to the more automated filter process. This was done by visual inspection and usually just involved a few points. This modified shapefile was saved under a new name.
Process_Step:
Process_Description:
The submarine typically travels very slowly to aid in seafloor observations. In fact, the submarine can't travel extremely fast. Because of this, I was able to write a filter that looked at distance traveled between each navigation point. I could vary the filter values and see which points were selected as acceptable based on the filter values. The visual inspection of what appeared sensible determined if the filter values were accepted.
Process_Step:
Process_Description:
Once a reasonable filter was applied, those selected points were then saved into a new shapefile with the filter values used added as an attribute to the file. The filter works such that the first number is the distance accepted as movement between 2 adjacent points in time. The second number is the increment added to each subsequent time step. This value is smaller than the first otherwise before long very large error values would be accepted.
Process_Step:
Process_Description:
Once the individual dives were processed, these files were then combined into one shapefile using the Geoprocessing wizard in ArcView 3.2a.

Overview_Description:
Entity_and_Attribute_Overview:
The navigation in sse_142 is suspect. There are large apparent jumps in navigation, then no change for an extended time. What appeared to be 2 major outliers bunches were deleted, and that was all the modifications on the original point navigation. Therefore, no actual filter was applied. Since this particular SSE dive falls outside the Pulley Ridge study area, this seemed acceptable.
