Title:
nav2002 - Navigation Tracklines of the Puerto Rico Trench Cruise 02051 (NOAA 0208) September 24 to September 30, 2002
Abstract:
The Puerto Rico trench is a tectonic plate boundary where the North American plate slides by and descends under the Caribbean plate. Although much of the trench lies within the U.S. EEZ, surprisingly few surveys have been conducted there during the past 25 years. This data set shows the tracklines (navigation path) of the U.S. Geological Survey science cruise that was conducted in the year 2002.
