Title:
ROV Point Navigation from 2001 in the Pulley Ridge are in the Gulf of Mexico based on 5-min navigation
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.

Why was the data set created?

This polyline shapefile indicates ROV tracks based on 5 minute navigation. These ROV tracklines were acquired in 2001 aboard Florida Institute of Oceanography's R/V Suncoaster and represent the tracks of the Deep Ocean Engineering Phantom S2.

How was the data set created?

  1. From what previous works were the data drawn?
  2. How were the data generated, processed, and modified?
    Date: unknown (process 1 of 7)
    Navigation was logged in the form of an excel spreadsheet at 5 minutes intervals. This spreadsheet was reformatted and exported to a delimited text format.
    Date: unknown (process 2 of 7)
    The delimited text format was imported into ArcView 3.3 as an event theme, and converted to a shapefile.
    Date: unknown (process 3 of 7)
    ArcToolbox (from version 8.3) was used to define the projection.

    Edits to the metadata were made to fix any errors that MP v 2.9.36 flagged. This is necessary to enable the metadata to be successfully harvested for various data catalogs. In some cases, this meant adding text "Information unavailable" or "Information unavailable from original metadata" for those required fields that were left blank. Other minor edits were probably performed (title, publisher, publication place, etc.). Attempted to modify http to https where appropriate. The link to the larger work citation had to be fixed. The standard order process section in the Distribution section was incomplete and had to be modified to meet the standard - which included adding a link to the data. Added ISO 19115 Topic Category keywords. 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.
