This coverage contains data associated with ROPOS dive #235s, conducted in 1993 (this dive was navigated with ship based navigation only). Purpose This is a research product and is not intended as an official publication of the National Oceanic and Atmospheric Administration (NOAA). The data contained in this coverage are intended for scientific research and should not be used for navigational purposes. Supplemental_Information Procedures_Used Procedures used to process data are as follows: 1. ROPOS data originally collected with GPS based navigation. 2. Data were then entered into GIS (see coverage log file for command process specifics). Performed by Andra Bobbitt. Revisions 1. No shifts as of 19960921 Reviews_Applied Data checked for completeness and integrity.

Access_Constraints n/a Use_Constraints The positional accuracy of the data contained in this coverage depends primarily on the accuracy of the navigation employed during data collection. These data were originally collected using GPS (selective availability). Positional accuracy may be variable.

Data_Quality_Information
Attribute_Accuracy Attribute_Accuracy_Report: See Logical_Consistency_Report: Chain-node topology present.Completeness_Report Navigational data were analyzed for erroneous fixes: points that were obvious outliers were removed from the data set. Positional_Accuracy Horizontal_Positional_Accuracy Horizontal_Positional_Accuracy_Report: Horizontal accuracy of data set is largely determined by both the accuracy of the navigation used during data acquisition and the ability to resolve the underwater position of the submersible relative to the ship. Navigational data were collected using GPS (selective availability). GPS with SA generally has an accuracy around 100m.
